LETTER TO OUR SHAREHOLDERS
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

Financial markets over the six-months ended September 30, 2006, were driven by a
widely anticipated "soft-landing" in the U.S. economy. This "goldilocks"
scenario had economic growth slowing, inflation and interest rates coming down
and the Federal Reserve ("Fed") ending its protracted string of increases. In
this environment, stocks rallied as corporate earnings continued to grow at
double digit rates without competition from higher interest rates. The icing on
the cake was relief from higher energy prices, which had risen relentlessly
since 2005.

While the rally in stocks was fairly broad-based, it definitely exhibited a
defensive bias. Large caps, value stocks and traditionally defensive sectors
generally outperformed small caps, growth stocks and more aggressive sectors.
This pattern is perfectly in keeping with the "late cycle" nature of the stock
market rally. Investors wanted to ride prices up, but wanted to hedge their bets
at the same time.

The large-cap nature of the rally was clearly evident in the performance of the
major averages. The home of the country's industrial giants--the Dow Jones
Industrial Average(SM)--returned 6.34%, followed by the broader S&P 500(R)
Index, which returned 4.14%. If we look at the extremes of the capitalization
spectrum, the large-cap bias becomes more evident as the Russell Top 50(TM)
Index returned 7.13% for the six month period versus a LOSS of 4.61% for the
small-cap Russell 2000(R) Index.

In a defensive rally, investors are often wary of overpaying for stocks. That
was certainly true as the Russell 1000(R) Value Index returned 5.5% versus a
0.7% decline for the Russell 1000(R) Growth Index. Although developed market
international stocks did well as the MSCI EAFE Index gained 3.2%, emerging
market stocks fared poorly as the MSCI EM Index fell 1.2%.

A major catalyst for the rally in stocks was the rally in bonds. While yields on
the short end of the curve actually rose, longer dated maturities rallied with
the yield on the benchmark 10-Year Treasury note declining to 4.63% from 4.85%
during the six-month period. The catalyst for falling rates was the decline in
inflation and the Fed's pause from its extended interest rate increases. The
result was a steeply inverted yield curve. Historically, inverted yield curves
presage an economic slowdown or recession. While that remains a possibility, the
decline in long-term rates also signals the market's anticipation of an eventual
easing campaign by the Fed.

The performance of stocks at the sector level highlighted the defensive bias
towards the gains in stock prices over the past six months. The S&P 500
Utilities sector led the way with a gain of 10.2%. Although telecommunications
services, a more aggressive sector, was number two with a gain of 8.1%, consumer
staples and financials were the next best performers, gaining 7.5% and 6.5%,
respectively. It is worth noting that falling interest rates also helped both
financials and utilities. Sectors that typically perform well in a rapidly
expanding economic environment, specifically materials, industrials and
technology declined between 1.0% and 2.3% as the economy slowed.

Going into the fourth quarter, we expect that Gross Domestic Product will pick
up slightly, the Fed will remain on hold and equities will remain range-bound.
As we head into 2007, we also see the appetite for risk continuing to decline.

We appreciate the trust you have placed in our firm by investing with us.

Sincerely,


/s/ David C. Reilly

A BRIEF NOTE ON THE COMPOUNDING OF RETURNS  (UNAUDITED)
- --------------------------------------------------------------------------------

Many of the Rydex Funds described in this report are benchmarked daily to
leveraged or inverse versions of published indices. To properly evaluate the
performance of these funds, it is essential to understand the effect of
mathematical compounding on their respective returns.

Because of the nonlinear effects of leverage applied over time, it is possible
for a fund to perform in line with its benchmark for several individual periods
in a row, yet seem to trail the benchmark over the entire period. It is also
possible that a fund that performs in-line with its benchmark on a daily basis
may seem to outperform its benchmark over longer periods.

AN EXAMPLE OF COMPOUNDING

For example, consider a hypothetical fund that is designed to produce returns
that correspond to 150% of an index. On the first day of a period, the index
rises from a level of 100 to a level of 106, producing a 6% gain and an
expectation that the fund will rise by 9%. On the same day, the fund's net asset
value ("NAV") increases from $10.00 to $10.90 for a gain of 9.0%-in line with
its benchmark.

On day two, assume the index falls from 106 to 99 for a loss of about 6.6%. The
fund, as expected, falls 9.9% to a price of $9.82. On each day, the fund
performed exactly in line with its benchmark, but for the two-day period, the
fund was down 1.8%, while the index was down only 1.0%. Without taking into
account the daily compounding of returns, one would expect the fund to lose 1.5%
and would see the fund as trailing by 0.3% when in fact it had performed
perfectly. This example is summarized in the table below.



              INDEX        INDEX         FUND                      FUND
              LEVEL     PERFORMANCE   EXPECTATION    FUND NAV   PERFORMANCE    ASSESSMENT
- ------------------------------------------------------------------------------------------
                                                              
Start         100                                     $10.00
Day 1         106          6.00%         9.00%        $10.90      9.00%         In line
Day 2          99         -6.60%        -9.90%        $ 9.82     -9.90%         In line
Cumulative                -1.00%        -1.50%                   -1.80%         -0.30%
- ------------------------------------------------------------------------------------------


As illustrated by this simple example, the effect of leverage can make it
difficult to form expectations or judgments about fund performance given only
the returns of the unleveraged index.

In general, any change in direction in an index will produce compounding that
seems to work against an investor. Were the index to move in the same direction
(either up or down) for two or more periods in a row, the compounding of those
returns would work in an investor's favor, causing the fund to seemingly beat
its benchmark.

As a general rule of thumb, more leverage in a fund will magnify the compounding
effect, while less leverage will generally produce results that are more in line
with expectations. In addition, periods of high volatility in an underlying
index will also cause the effects of compounding to be more pronounced, while
lower volatility will produce a more muted effect.

ABOUT SHAREHOLDERS' FUND EXPENSES  (UNAUDITED)
- --------------------------------------------------------------------------------

All mutual funds have operating expenses and it is important for our
shareholders to understand the impact of costs on their investments. As a
shareholder of the fund, you incur two types of costs: (i) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (ii) ongoing costs,
including management fees, administrative services, and shareholder reports,
among others. These ongoing costs, or operating expenses, are deducted from a
fund's gross income and reduce the investment return of the fund.

A fund's expenses are expressed as a percentage of its average net assets, which
is known as the expense ratio. The following examples are intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
The examples are based on an investment of $1,000 made at the beginning of the
period and held for the entire six-month period beginning March 31, 2006 and
ending September 30, 2006.

The following tables illustrate your fund's costs in two ways:

TABLE 1. BASED ON ACTUAL FUND RETURN. This section helps you estimate the actual
    expenses that you paid over the period. The "Ending Account Value" shown
    is derived from the fund's actual return, and the fourth column shows the
    dollar amount that would have been paid by an investor who started with
    $1,000 in the fund. You may use the information here, together with the
    amount you invested, to estimate the expenses that you paid over the
    period. Simply divide your account value by $1,000 (for example, an $8,600
    account value divided by $1,000 = 8.6), then multiply the result by the
    number given for your fund under the heading "Expenses Paid During
    Period."

TABLE 2. BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help you
    compare your fund's cost with those of other mutual funds. The table
    provides information about hypothetical account values and hypothetical
    expenses based on the Fund's actual expense ratio and an assumed rate of
    return of 5% per year before expenses, which is not the Fund's actual
    return. The hypothetical account values and expenses may not be used to
    estimate the actual ending account balance or expenses you paid during the
    period. The example is useful in making comparisons because the U.S.
    Securities and Exchange Commission (the "SEC") requires all mutual funds
    to calculate expenses based on the 5% return. You can assess your fund's
    costs by comparing this hypothetical example with the hypothetical
    examples that appear in shareholder reports of other funds.

Certain retirement plans such as IRA, Roth IRA and 403(b) accounts are charged
an annual $15 maintenance fee. Upon liquidating your retirement account, a $15
account-closing fee will be taken from the proceeds of your redemption.

The calculations above assume no shares were bought or sold during the period.
Your actual costs may have been higher or lower, depending on the amount of your
investment and the timing of any purchases or redemptions.

Note that the expenses shown in the table are meant to highlight and help you
compare ongoing costs only and do not reflect any transactional costs which may
be incurred by some of the Fund's classes. These costs may include, but are not
limited to, sales charges (loads), redemption fees, and exchange fees.

You can find more information about the Fund's expenses, including annual
expense ratios for the past five years, in the Financial Highlights section of
this report. For additional information on operating expenses and other
shareholder costs, please refer to the appropriate Fund prospectus.

MASTER-FEEDER ARRANGEMENT
- --------------------------------------------------------------------------------

Nova Fund, Inverse S&P 500 Fund, Inverse OTC Fund and Inverse Government Long
Bond Fund are operating under a `master-feeder arrangement'. Under a
master-feeder arrangement, a Feeder Fund ("feeder") invests substantially all of
its assets in the Master Portfolio ("master"), a separate open-ended investment
company that has the same investment objectives as the feeder, e.g., the Nova
Fund would act as a feeder, holding shares of the Nova Master Portfolio as its
only investment. The Master Portfolio, in turn, invests in securities and
derivatives to meet its investment objective.

The Feeder Fund is the sole shareholder of the Master Portfolio and is the only
part of the master-feeder relationship in which shareholders can invest. As a
shareholder of a Feeder Fund, you have indirect ownership of the investments of
the corresponding Master Portfolio. Therefore, the Schedules of Investments of
the masters are provided here to illustrate securities in which the masters
invest and, indirectly, what the feeders hold. Please see Notes to Financial
Statements for more information about the master-feeder arrangement.

MASTER-FEEDER ARRANGEMENT
- --------------------------------------------------------------------------------

Nova Fund, Inverse S&P 500 Fund, Inverse OTC Fund and Inverse Government Long
Bond Fund are operating under a 'master-feeder arrangement'. Under a
master-feeder arrangement, a Feeder Fund ("feeder") invests substantially all of
its assets in the Master Portfolio ("master"), a separate open-ended investment
company that has the same investment objectives as the feeder, e.g., the Nova
Fund would act as a feeder, holding shares of the Nova Master Portfolio as its
only investment. The Master Portfolio, in turn, invests in securities and
derivatives to meet its investment objective.

The following statements represent the Feeder Funds, which is the part of the
master-feeder arrangement in which shareholders invest. Please see Notes to
Financial Statements for more information about the master-feeder arrangement.

MASTER-FEEDER ARRANGEMENT
- --------------------------------------------------------------------------------

Nova Fund, Inverse S&P 500 Fund, Inverse OTC Fund and Inverse Government Long
Bond Fund are operating under a `master-feeder arrangement'. Under a
master-feeder arrangement, a Feeder Fund ("feeder") invests substantially all of
its assets in the Master Portfolio ("master"), a separate open-ended investment
company that has the same investment objectives as the feeder, e.g., the Nova
Fund would act as a feeder, holding shares of the Nova Master Portfolio as its
only investment. The Master Portfolio, in turn, invests in securities and
derivatives to meet its investment objective.

The following statements represent the Master Portfolios, which is the part of
the master-feeder arrangement in which Feeder Funds invest. Please see Notes to
Financial Statements for more information about the master-feeder arrangement.

1. SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the SEC under the
Investment Company Act of 1940 (the "1940 Act") as a non-diversified, open-ended
investment company, and is authorized to issue an unlimited number of no par
value shares. The Trust offers five separate classes of shares, Investor Class
Shares, Advisor Class Shares, A-Class Shares, C-Class Shares, and H-Class
Shares. C-Class Shares have a 1% Contingent Deferred Sales Charge ("CDSC") if
Shares are redeemed within 12 months of purchase. Sales of shares of each Class
are made without a sales charge at the net asset value per share, with the
exception of A-Class Shares. A-Class Shares are sold at net asset value, plus
the applicable front-end sales charge. The sales charge varies depending on the
amount of your purchase, but will not exceed 4.75%. A-Class Share purchases of
$1 million or more have a 1% CDSC if Shares are redeemed within 18 months of
purchase. The current sales charge rates are as follows:

                                            SALES CHARGE          SALES CHARGE

At September 30, 2006, the Trust consisted of fifty-three separate series:
twenty-six Benchmark Funds, one Money Market Fund, four Alternative Strategy
Funds, and three Essential Portfolio Funds. This report covers the twenty-six
Benchmark Funds and the Money Market Fund (the "Funds"), while the Sector Funds,
the Alternative Strategy Funds, and the Essential Portfolio Funds are contained
in separate reports.

The following significant accounting policies are in conformity with accounting
principles generally accepted in the United States of America and are
consistently followed by the Trust.

A. Effective May 31, 2006, the Trust began calculating a net asset value per
share ("NAV") twice each business day, first in the morning and again in the
afternoon for the Russell 2000 Fund and the S&P 500 Fund. All other Funds in the
Trust will price at the afternoon NAV. The morning NAV is calculated at 10:45
a.m., Eastern Time, and the afternoon NAV is calculated at the close of the New
York Stock Exchange ("NYSE"), usually 4:00 p.m., Eastern Time. The NAV is
calculated using the current market value of each Fund's total assets as of the
respective time of calculation. These financial statements are based on the
September 30, 2006 afternoon NAV.

B. All equity securities for the morning NAV are valued at the current sales
price as of 10:45 a.m., Eastern Time, on the valuation date. Equity securities
listed on an exchange (New York Stock Exchange ("NYSE") or American Stock
Exchange) are valued at the last quoted sales price as of the close of business
on the NYSE, usually 4:00 p.m., Eastern Time, on the valuation date for the
afternoon NAV. Equity securities listed on the Nasdaq market system are valued
at the Nasdaq Official Closing Price, usually as of 4:00 p.m., Eastern Time, on
the valuation date. Listed options held by the Trust are valued at the Official
Settlement Price listed by the exchange, usually as of 4:00 p.m., Eastern Time.
Over-the-Counter options held by the Trust are valued using the average bid
price obtained from one or more security dealers. The value of futures contracts
purchased and sold by the Trust are accounted for using the unrealized gain or
loss on the contracts that is determined by marking the contracts to their
current realized settlement prices. Financial futures contracts are valued as of
10:45 a.m., Eastern Time, on the valuation date for the morning pricing cycle.
Financial futures contracts are valued at the last quoted sales price, usually
as of 4:00 p.m., Eastern Time, on the valuation date for the afternoon NAV
cycle. In the event that the exchange for a specific futures contract closes
earlier than 4:00 p.m., Eastern Time, the futures contract is valued at the
Official Settlement Price of the exchange. However, the underlying securities
from which the futures contract value is derived are monitored until 4:00 p.m.,
Eastern Time, to determine if fair valuation would provide a more accurate
valuation. Short-term securities, if any, are valued at amortized cost, which
approximates market value.

The value of domestic equity index swap agreements entered into by a Fund is
accounted for using the unrealized gain or loss on the agreements that is
determined by marking the agreements to the last quoted value of the index that
the swap pertains to at 10:45 a.m., Eastern Time, for the morning NAV, and at
the close of the NYSE, usually 4:00 p.m., Eastern Time, for the afternoon NAV.
The swap's market value is then adjusted to include dividends accrued, financing
charges and/or interest associated with the swap agreements.

The value of foreign equity index, commodity index, and currency index swap
agreements entered into by a Fund is accounted for using the unrealized gain or
loss on the agreements that is determined by marking the agreements to the price
at which orders are being filled at the close of the NYSE, usually 4:00 p.m.,
Eastern Time. In the event that no order is filled at 4:00 p.m., Eastern Time,
the security dealer provides a fair value quote at which the swap agreement is
valued. The swap's market value is then adjusted to include

NOTES TO FINANCIAL STATEMENTS  (UNAUDITED) (CONTINUED)

dividends accrued, financing charges and/or interest associated with the swap
agreements.

Investments for which market quotations are not readily available are valued at
fair value as determined in good faith by Rydex Investments (the "Advisor"), an
affiliated entity under direction of the Board of Trustees using methods
established or ratified by the Board of Trustees. These methods include, but are
not limited to: (i) general information as to how these securities and assets
trade; (ii) in connection with futures contracts and options thereupon, and
other derivative investments, information as to how (a) these contracts and
other derivative investments trade in the futures or other derivative markets,
respectively, and (b) the securities underlying these contracts and other
derivative investments trade in the cash market; and (iii) other information and
considerations, including current values in related markets. The shares of the
Master Portfolios held by the Feeder Funds are valued at their respective daily
Net Asset Value.

C. Securities transactions are recorded on the trade date for financial
reporting purposes. Realized gains and losses from securities transactions are
recorded using the identified cost basis. Proceeds from lawsuits related to
investment holdings are recorded as realized gains in the respective Fund.
Dividend income is recorded on the ex-dividend date, net of applicable taxes
withheld by foreign countries. Interest income, including amortization of
premiums and accretion of discount, is accrued on a daily basis.

D. Net investment income is computed and dividends are declared daily in the
Government Long Bond Advantage Fund and the U.S. Government Money Market Fund.
Income dividends in these Funds are paid daily. Dividends are reinvested in
additional shares unless shareholders request payment in cash. Distributions of
net investment income in the remaining Benchmark Funds and distributions of net
realized capital gains in all Funds are recorded on the ex-dividend date and are
determined in accordance with income tax regulations which may differ from
accounting principles generally accepted in the United States of America. These
differences are primarily due to differing treatments for items such as deferral
of wash sales and post-October losses and regulated futures contracts and
options. Net investment income and loss, net realized gains and losses, and net
assets are not affected by these differences.

E. When a Fund engages in a short sale, an amount equal to the proceeds is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked-to-market to reflect the market value of the short sale.
The Fund maintains a segregated account of cash and/or securities as collateral
for short sales. The Fund is exposed to market risk based on the amount, if any,
that the market value of the security exceeds the market value of the securities
in the segregated account. Fees, if any, paid to brokers to borrow securities in
connection with short sales are considered part of the cost of short sale
transactions. In addition, the Fund must pay out the dividend rate of the equity
or coupon rate of the treasury obligation to the purchaser and records this as
an expense. Short Dividends or Interest Expense is a cost associated with the
investment objective of short sales transactions, rather than an operational
cost associated with the day-to-day management of any mutual fund. Currently,
the Inverse Government Long Bond Master Portfolio is the only fund practicing
the use of short sales.

F. Upon the purchase of an option by a Fund, the premium paid is recorded as an
investment, the value of which is marked-to-market daily. When a purchased
option expires, the Fund will realize a loss in the amount of the cost of the
option. When the Fund enters into a closing sale transaction, the Fund will
realize a gain or loss depending on whether the proceeds from the closing sale
transaction are greater or less than the cost of the option. When a Fund
exercises a put option, it will realize a gain or loss from the sale of the
underlying security and the proceeds from such sale will be decreased by the
premium originally paid. When a Fund exercises a call option, the cost of the
security that the Fund purchases upon exercise will be increased by the premium
originally paid. When a Fund writes (sells) an option, an amount equal to the
premium received is entered in the Trust's accounting records as an asset and
equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current value of the option written. When a
written option expires, or if the Fund enters into a closing purchase
transaction, the Fund realizes a gain (or loss if the cost of a closing purchase
transaction exceeds the premium received when the option was sold).

G. The Trust may purchase or sell stock and bond index futures contracts and
options on such futures contracts. Futures contracts are contracts for delayed
delivery of securities at a specified future delivery date and at a specific
price. Upon entering into a contract, a Fund deposits and maintains as
collateral such initial margin as required by the exchange on which the
transaction is effected. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the contract is
closed, the Fund records a realized gain or loss equal to the difference between
the


126 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS  (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

value of the contract at the time it was opened and the value at the time it was
closed.

H. The Trust may enter into swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified equity security, basket of equity
securities, equity index, commodity index, or U.S. Dollar index, in return for
periodic payments based on a fixed or variable interest rate or the change in
market value of a different equity security, basket of equity securities, equity
index, commodity index, or U.S. Dollar index. Swap agreements are used to obtain
exposure to an equity or market without owning or taking physical custody of
securities.

I. Investment securities and other assets and liabilities denominated in foreign
currencies are translated into U.S. dollar amounts at the date of valuation.
Purchases and sales of investment securities and income and expense items
denominated in foreign currencies are translated into U.S. dollar amounts on the
respective dates of such transactions. The Trust does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments from the fluctuations arising from changes in market prices of
securities held. Such fluctuations are included with the net realized and
unrealized gain and loss from investments.

Reported net realized foreign exchange gains or losses arise from sales of
foreign currencies and currency gains or losses realized between the trade and
settlement dates on investment transactions. Net unrealized exchange gains and
losses arise from changes in the fair values of assets and liabilities other
than investments in securities at the fiscal period end, resulting from changes
in exchange rates.

J. The Trust may enter into forward currency contracts primarily to hedge
against foreign currency exchange rate risks on its non-U.S. dollar denominated
investment securities. When entering into a forward currency contract, a Fund
agrees to receive or deliver a fixed quantity of foreign currency for an
agreed-upon price on an agreed future date. These contracts are valued daily and
the corresponding unrealized gain or loss on the contracts, as measured by the
difference between the forward foreign exchange rates at the dates of entry into
the contracts and the forward rates at the reporting date, is included in the
Statement of Assets and Liabilities. Realized and unrealized gains and losses
are included in the Statement of Operations.

K. The Funds may also purchase American Depository Receipts, U.S. Government
securities, enter into repurchase agreements, and engage in futures, options and
swap transactions.

L. The Funds may leave cash overnight in their cash account with the custodian,
U.S. Bancorp. Periodically, a Fund may have cash due to custodian bank as an
overdraft balance. A fee is incurred on this overdraft, calculated by
multiplying the overdraft by a rate based on the federal funds rate. Segregated
cash with the broker is held as collateral for investments in derivative
instruments such as futures contracts and index swap agreements.

M. Certain U.S. Government and Agency Obligations are traded on a discount
basis; the interest rates shown on the Schedules of Investments reflect the
discount rates paid at the time of purchase by a Fund. Other securities bear
interest at the rates shown, payable at fixed dates through maturity.

N. Interest and dividend income, most expenses, all realized gains and losses,
and all unrealized gains and losses are allocated to the Classes based upon the
value of the outstanding shares in each Class. Certain costs, such as
distribution fees relating to Advisor Class Shares, A-Class Shares and H-Class
Shares and service and distribution fees related to C-Class Shares, are charged
directly to specific Classes. In addition, certain expenses have been allocated
to the individual Funds in the Trust on a pro rata basis upon the respective
aggregate net asset value of each Fund included in the Trust.

O. The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amount of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from these
estimates.

2. FINANCIAL INSTRUMENTS

As part of its investment strategy, the Trust may utilize a variety of
derivative instruments, including options, futures, options on futures, swap
agreements, and short sales. These investments involve, to varying degrees,
elements of market risk and risks in excess of the amounts recognized in the
Statements of Assets and Liabilities.

In the normal course of business, the Funds enter into contracts that contain a
variety of representations and warranties, which provide general
indemnifications. The Funds' maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Funds
and/or its affiliates that have not yet occurred. However, based on experience,
the Funds expect the risk of loss to be remote.

The risk associated with purchasing options is limited to the premium originally
paid. Options written by a Fund


                                 THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT | 127


NOTES TO FINANCIAL STATEMENTS  (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

involve, to varying degrees, risk of loss in excess of the option value
reflected in the Statements of Assets and Liabilities. The risk in writing a
covered call option is that a Fund may forego the opportunity for profit if the
market price of the underlying security increases and the option is exercised.
The risk in writing a covered put option is that a Fund may incur a loss if the
market price of the underlying security decreases and the option is exercised.
In addition, there is the risk that a Fund may not be able to enter into a
closing transaction because of an illiquid secondary market or, for
over-the-counter options, because of the counterparty's inability to perform.
The Trust has established strict counterparty credit guidelines and enters into
transactions only with financial institutions of investment grade or better.

There are several risks in connection with the use of futures contracts. Futures
contracts involve, to varying degrees, risk of loss in excess of amounts
reflected in the financial statements. Risks may be caused by an imperfect
correlation between movements in the price of the instruments and the price of
the underlying securities. In addition, there is the risk that a Fund may not be
able to enter into a closing transaction because of an illiquid secondary
market.

The use of equity swaps and commodity linked notes involves risks that are
different from those associated with ordinary portfolio securities transactions.
Swap agreements may be considered to be illiquid. Although the Trust will not
enter into any swap agreement unless the Advisor believes that the other party
to the transaction is creditworthy, the Funds bear the risk of loss of the
amount expected to be received under a swap agreement in the event of the
default or bankruptcy of the agreement counterparty. The Trust has established
strict counterparty credit guidelines and enters into transactions only with
financial institutions of investment grade or better.

Short sales are transactions in which a Fund sells a security it does not own.
If the security the Fund sold short goes down in price between the time the Fund
sells the security and closes its short position, the Fund will realize a gain
on the transaction. Conversely, if the security goes up in price during the
period, the Fund will realize a loss on the transaction. The risk of such price
increases is the principal risk of engaging in short sales.

In conjunction with the use of options, futures, options on futures, swap
agreements, as well as short sales of securities, the Funds are required to
maintain collateral in various forms. The Funds use, where appropriate,
depending on the financial instrument utilized and the broker involved, margin
deposits at the broker, cash and/or securities segregated at the custodian bank,
discount notes, or the repurchase agreements allocated to each Fund.

The risks inherent in the use of options, futures contracts, options on futures
contracts, swap agreements, as well as short sales of securities, include i)
adverse changes in the value of such instruments; ii) imperfect correlation
between the price of the instruments and movements in the price of the
underlying securities, indices, or futures contracts; iii) the possible absence
of a liquid secondary market for any particular instrument at any time; and iv)
the potential of counterparty default.

3. MASTER-FEEDER ARRANGEMENT

Currently, the Nova Fund, the Inverse S&P 500 Fund, the Inverse Government Long
Bond Fund, and the Inverse OTC Fund are operating under a "master-feeder
arrangement." Under a master-feeder arrangement, a Fund invests substantially
all of its assets in the Master Portfolio, a separate open-ended investment
company that has the same investment objectives as the Fund, e.g., the Nova Fund
would act as a "feeder fund, "holding shares of its Master Portfolio as its only
investment. As a result, the Fund has an indirect interest in all of the
securities owned by the Master Portfolio. Because of this indirect interest, the
Fund's investment returns should be the same as those of the Master Portfolio,
adjusted for Fund expenses. The financial statements of the Master Portfolios,
including the Schedule of Investments, are included in this report and should be
read in conjunction with the Funds' financial statements. The percentage of Nova
Master Portfolio, Inverse S&P 500 Master Portfolio, Inverse OTC Master
Portfolio, and Inverse Government Long Bond Master Portfolio owned by the Nova
Fund, the Inverse S&P 500 Fund, the Inverse OTC Fund, and the Inverse Government
Long Bond Fund, respectively, at September 30, 2006, was 100 percent. The Funds
record their investments in the Master Portfolio at fair value. Valuation of
securities held by the Master Portfolio is discussed in Note 1, Significant
Accounting Policies.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of an investment advisory contract, the Trust pays the Advisor,
an affiliated entity, investment advisory fees calculated at an annualized rate
of 0.50% of the average daily net assets of the Government Long Bond Advantage
Fund and the U.S. Government Money Market Fund; 0.75% of the average daily net
assets of the S&P 500 Fund, the OTC Fund, the Russell 2000(R) Fund, the
Small-Cap Value Fund, the Mid-Cap Value Fund, the Large-Cap Value Fund, the
Small-Cap Growth Fund, the Mid-Cap Growth Fund, the Large-Cap Growth Fund, and
the Nova Master Portfolio; and 0.90% of the average daily net assets of the
Mid-Cap Advantage Fund, the Inverse Mid-Cap Fund, the Russell 2000(R) Advantage
Fund, the Inverse Russell 2000(R) Fund, the


128 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS  (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

Europe Advantage Fund, the Japan Advantage Fund, the Dynamic Strengthening
Dollar Fund, the Dynamic Weakening Dollar Fund, the Inverse S&P 500 Master
Portfolio, the Inverse OTC Master Portfolio, and the Inverse Government Long
Bond Master Portfolio. Certain officers and trustees of the Trust are also
officers of the Advisor.

Rydex Investments, an affiliated entity, provides transfer agent and
administrative services to the Trust for fees calculated at an annualized rate
of 0.20% of the average daily net assets of the Government Long Bond Advantage
Fund and the U.S. Government Money Market Fund; and 0.25% of the average daily
net assets of the Nova Fund, the S&P 500 Fund, the Inverse S&P 500 Fund, the OTC
Fund, the Inverse OTC Fund, the Mid-Cap Advantage Fund, the Inverse Mid-Cap
Fund, the Russell 2000(R) Advantage Fund, the Russell 2000(R) Fund, the Inverse
Russell 2000(R) Fund, the Inverse Government Long Bond Fund, the Europe
Advantage Fund, the Japan Advantage Fund, the Small-Cap Value Fund, the Mid-Cap
Value Fund, the Large-Cap Value Fund, the Small-Cap Growth Fund, the Mid-Cap
Growth Fund, and the Large-Cap Growth Fund, the Dynamic Strengthening Dollar
Fund, and the Dynamic Weakening Dollar Fund.

Rydex Investments also provides accounting services to the Trust calculated at
an annualized rate of 0.10% on the first $250 million of the average daily net
assets, 0.075% on the next $250 million of the average daily net assets, 0.05%
on the next $250 million of the average daily net assets, and 0.03% on the
average daily net assets over $750 million of each of the Funds. Certain
officers and trustees of the Trust are also officers of Rydex Investments.

Rydex Investments also provides other necessary services to the Trust, such as
accounting and auditing services, legal services, printing and mailing, etc., on
a pass-through basis. Such expenses vary from Fund to Fund and are allocated to
the Funds based on relative net assets. The Trust has adopted a Distribution and
Shareholder Services Plan applicable to Advisor Class Shares and a Distribution
Plan applicable to A-Class Shares and H-Class Shares for which Rydex
Distributors, Inc. (the "Distributor"), an affiliated entity, and other firms
that provide distribution and/or shareholder services ("Service Providers") may
receive compensation. If a Service Provider provides distribution services, the
Trust will pay distribution fees to the Distributor at an annual rate not to
exceed 0.25% of average daily net assets, pursuant to Rule 12b-1 of the 1940
Act. The Distributor, in turn, will pay the Service Provider out of its fees.
The Distributor may, at its discretion, retain a portion of such payments to
compensate itself for distribution services. With regard to Advisor Class Shares
only, if a Service Provider provides shareholders services, the Distributor will
receive shareholder servicing fees from the Trust at an annual rate not to
exceed 0.25% of average daily net assets. The Distributor, in turn, will pay the
Service Provider out of its fees.

The Trust has adopted a separate Distribution and Shareholder Services Plan
applicable to its C-Class Shares that allows the Funds to pay annual
distribution and service fees of 1.00% of the Funds' C-Class Shares average
daily net assets. The annual 0.25% service fee compensates the shareholder's
financial advisor for providing on-going services to the shareholder. The annual
0.75% distribution fee reimburses the Distributor for paying the shareholder's
financial advisor an ongoing sales commission. The Distributor advances the
first year's service and distribution fees to the Financial Advisor. The
Distributor retains the service and distribution fees on accounts with no
authorized dealer of record. Certain officers and trustees of the Trust are also
officers of the Distributor.

5. FEDERAL INCOME TAX INFORMATION

The Funds intend to comply with the provisions of the Internal Revenue Code
applicable to regulated investment companies and will distribute all net
investment income and capital gains to shareholders. Therefore, no Federal
income tax provision is required.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. These differences are primarily due to
differing treatments for derivatives, foreign currency transactions, losses
deferred due to wash sales, losses deferred due to post-October losses, and
excise tax regulations.

Permanent book and tax basis differences, if any, relating to shareholder
distributions will result in reclassifications to paid-in capital. This includes
net operating losses not utilized during the current period, net operating
losses offset with short-term capital gains, capital loss carryforward expired,
and the utilization of earnings and profits distributed to the shareholders on
redemption of shares as part of the dividends paid deduction for income tax
purposes. These reclassifications have no effect on net assets or net asset
values per share. Any taxable gain remaining at fiscal year end is distributed
in the following year.

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN
48). FIN 48 provides guidance for how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be


                                 THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT | 129


NOTES TO FINANCIAL STATEMENTS  (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

taken in the course of preparing the Fund's tax returns to determine whether the
tax positions are "more-likely-than-not" of being sustained by the applicable
tax authority. Tax positions not deemed to meet the more-likely-than-not
threshold would be recorded as a tax benefit or expense in the current year.
Adoption of FIN 48 is required for fiscal years beginning after December 15,
2006 and is to be applied to all open tax years as of the effective date. At
this time, management is evaluating the implications of FIN 48 and its impact in
the financial statements has not yet been determined.

At September 30, 2006, the cost of securities for Federal income tax purposes,
the aggregate gross unrealized gain for all securities for which there was an
excess of value over tax cost and the aggregate gross unrealized loss for all
securities for which there was an excess of tax cost over value were as follows:



                                                               TAX   TAX UNREALIZED   TAX UNREALIZED    NET UNREALIZED

6. REPURCHASE AGREEMENTS

The Funds transfer uninvested cash balances into a single joint account, along
with uninvested cash balances of the Absolute Return Strategies Fund, the Hedged
Equity Fund and the Multi-Cap Core Equity Fund (all included in the Trust, but
contained in separate reports). The daily aggregate balance is invested in one
or more repurchase agreements collateralized by obligations of the U.S.
Treasury. The collateral is in the possession of the Trust's custodian and is
evaluated daily to ensure that its market value exceeds by, at a minimum, 102%
of the delivery value of the repurchase agreement at maturity.

The repurchase agreements executed by the joint account and outstanding as of
September 30, 2006, were as follows:

In the event of counterparty default, the Trust has the right to collect the
collateral to offset losses incurred. There is potential loss to the Trust in
the event the Trust is delayed or prevented from exercising its rights to
dispose of the collateral securities, including the risk of a possible decline
in the value of the underlying securities during the period while the Trust
seeks to assert its rights. The Trust's investment advisor, acting under the
supervision of the Board of Trustees, reviews the value of the collateral and
the credit worthiness of those banks and dealers with which the Trust enters
into repurchase agreements to evaluate potential risks.

9. PORTFOLIO SECURITIES LOANED

The Trust lends its securities to approved brokers to earn additional income.
Security lending income shown on the statement of operations is shown net of
rebates paid to borrowers and earnings on cash collateral investments shared
with the lending agent. Within this arrangement, the Trust acts as the lender,
U.S. Bancorp acts as the agent, and other approved registered broker dealers act
as the borrowers. The Trust receives cash collateral, valued at 100% of the
value of the securities on loan, which is initially held in a segregated account
at U.S. Bancorp. As agent, U.S. Bancorp may, for investment purposes, pool the
Trust's collateral in joint accounts with cash collateral from one or more other
securities lending customers of U.S. Bancorp. Under the terms of the Trust's
securities lending agreement with U.S. Bancorp, cash collateral may be invested
by U.S. Bancorp in certain high quality, liquid investments. At September 30,
2006, the pooled cash collateral investments consisted of repurchase agreements
(46.60%), commercial paper (34.12%), fixed income securities (15.48%),
guaranteed investment contract (3.67%), and mutual funds (0.13%). Collateral is
maintained over the life of the loan in an amount not less than the value of
loaned securities, as determined at the close of fund business each day; any
additional collateral required due to changes in security values is delivered to
the Fund the next business day. Although the collateral mitigates risk, the
Trust could experience a delay in recovering its securities and a possible loss
of income or value if the borrower fails to return the securities. The Trust has
the right under the securities lending agreement to recover the securities from
the borrower on demand.

The following represents a breakdown of the collateral, its rates, and
maturities.

10. CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board has selected Ernst & Young LLP ("E&Y") to serve as the Funds'
independent registered public accounting firm for the fiscal year ended March
31, 2007. The decision to select E&Y was recommended by the Audit Committee and
was approved by the Board on September 25, 2006. During the Funds' fiscal years
ended March 31, 2006 and March 31, 2005, none of the Funds, their portfolios nor
anyone on their behalf consulted with E&Y on items which (i) concerned the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Funds' financial statements; or (ii) concerned the subject of a disagreement
(as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable
events (as described in paragraph (a)(1)(iv) of said Item 304).

The selection of E&Y does not reflect any disagreements with or dissatisfaction
by the Funds or the Board with the performance of the Funds' prior auditor,
PricewaterhouseCoopers LLP ("PwC"). The decision to dismiss PwC effective upon
its completion of its audits for the fiscal year ended March 31, 2006 and to
select E&Y was recommended by the Funds' Audit Committee and approved by the
Funds' Board of Trustees. PwC's report on the Funds' financial statements for
the fiscal years ended March 31, 2006 and 2005 contained no adverse opinion or
disclaimer of opinion nor were they qualified or modified as to uncertainty,
audit scope or accounting principles. During the Funds' fiscal years ended March
31, 2006

and March 31, 2005, (i) there were no disagreements with PwC on any matter of
accounting principles or practices, financial statement disclosure or auditing
scope or procedure, which disagreements, if not resolved to the satisfaction of
PwC, would have caused it to make reference to the subject matter of the
disagreements in connection with its report on the Funds' financial statements
for such years, and (ii) there were no "reportable events" of the kind described
in Item 304(a)(1)(v) of Regulation SK under the Securities and Exchange Act of
1934, as amended.

RYDEX INVESTMENTS BOARD REVIEW AND APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

The Investment Company Act of 1940 (the "1940 Act") requires that the initial
approval of, as well as the continuation of, a fund's investment advisory
agreement be specifically approved (1) by the vote of the trustees or by a vote
of the shareholders of the fund, and (2) by the vote of a majority of the
trustees who are not parties to the investment advisory agreement or "interested
persons" of any party (the "Independent Trustees"), cast in person at a meeting
called for the purpose of voting on such approval. In connection with such
approvals, the fund's trustees must request and evaluate, and the investment
adviser is required to furnish, such information as may be reasonably necessary
to evaluate the terms of the advisory agreement. In addition, the Securities and
Exchange Commission (the "SEC") takes the position that, as part of their
fiduciary duties with respect to fund fees, fund boards are required to evaluate
the material factors applicable to a decision to approve an investment advisory
agreement.

Consistent with these responsibilities, the Rydex Series Funds Board of Trustees
(the "Board") calls and holds one meeting each year that is dedicated to
considering whether to renew the investment advisory agreement between Rydex
Series Funds (the "Trust") and PADCO Advisors, Inc., which does business under
the name Rydex Investments ("Rydex Investments"), (the "Advisory Agreement")
with respect to existing funds in the Trust, including the funds discussed in
this Semi-Annual Report (each a "Fund" and collectively, the "Funds"), and to
reviewing certain other agreements pursuant to which Rydex Investments provides
investment advisory services to certain other registered investment companies.
In preparation for the meeting, the Board requests and reviews a wide variety of
materials provided by Rydex Investments, including information about Rydex
Investments' affiliates, personnel and operations. The Board also receives data
provided by third parties. This information is in addition to the detailed
information about the Funds that the Board reviews during the course of each
year, including information that relates to Fund operations and performance. The
Board also receives a memorandum from Fund counsel regarding the
responsibilities of the Board for the approval of investment advisory
agreements. In addition, the Independent Trustees receive advice from
independent counsel to the Independent Trustees, meet in executive session
outside the presence of fund management, and participate in question and answer
sessions with representatives of Rydex Investments.

At a meeting held on August 27 and 28, 2006, the Board approved the selection of
Rydex Investments and the continuance of the Advisory Agreement for an
additional one-year period, based on its review of qualitative and quantitative
information provided by Rydex Investments. The Board's approval of the Advisory
Agreement was based on consideration and evaluation of a variety of specific
factors discussed at that meeting and at prior meetings, including:

      NATURE, EXTENT AND QUALITY OF SERVICES PROVIDED BY RYDEX INVESTMENTS

      The Board reviewed the scope of services to be provided by Rydex
      Investments under the Advisory Agreement and noted that there would be no
      significant differences between the scope of services required to be
      provided by Rydex Investments for the past year and the scope of services
      required to be provided by Rydex Investments for the upcoming year. In
      reviewing the scope of services provided to the Funds by Rydex
      Investments, the Board reviewed and discussed Rydex Investments'
      investment experience, noting that Rydex Investments and its affiliates
      have committed significant resources over time to the support of the
      Funds. The Board also considered Rydex Investments' compliance program and
      its compliance record with respect to the Funds. In that regard, the Board
      noted that Rydex Investments provides information regarding the portfolio
      management and compliance to the Board on a periodic basis in connection
      with regularly scheduled meetings of the Board. In addition to the above
      considerations, the Board reviewed and considered Rydex Investments'
      investment processes and strategies, and matters related to Rydex
      Investments' portfolio


                                 THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT | 137


OTHER INFORMATION  (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      transaction policies and procedures. In particular, the Board noted the
      substantial volume of portfolio trades and shareholder transaction
      activity, in general, processed by Rydex Investments due to the unlimited
      exchange policy of the majority of the Funds. The Board further noted that
      the Funds have met their investment objectives consistently since their
      relevant inception dates. Based on this review, the Board concluded that
      the nature, extent and quality of services to be provided by Rydex
      Investments to the Funds under the Advisory Agreement were appropriate and
      continued to support the Board's original selection of Rydex Investments
      as investment adviser to the Funds.

      FUND EXPENSES AND PERFORMANCE OF THE FUNDS AND RYDEX INVESTMENTS

      The Board reviewed statistical information prepared by Rydex Investments
      regarding the expense ratio components, including actual advisory fees,
      waivers/reimbursements, and gross and net total expenses of each Fund in
      comparison with the same information for other funds registered under the
      1940 Act determined by Rydex Investments to comprise each Fund's
      applicable peer group. Because few funds seek to provide unlimited
      exchange privileges similar to those of the Funds (other than the
      Commodities Fund, Multi-Cap Core Equity Fund, Sector Rotation Fund,
      Absolute Return Strategies Fund, and Hedged Equity Fund), each Fund's
      applicable peer group is generally limited to the funds of two
      unaffiliated mutual fund families. In addition, the Board reviewed
      statistical information prepared by Rydex Investments relating to the
      performance of each Fund, as well as each Fund's ability to successfully
      track its benchmark over time, and a comparison of each Fund's performance
      to funds with similar investment objectives for the same periods and to
      appropriate indices/benchmarks, in light of total return, yield and market
      trends. The Board further noted that despite the unique nature of the
      Funds, the peer fund information presented to the Board was meaningful
      because the peer funds' investment objectives and strategies were closely
      aligned with those of the Funds. The Board noted that most of the Funds
      either outperformed their peer funds or performed in line with them over
      relevant periods. The Board also noted that the investment advisory fees
      and overall expenses for the Funds were generally lower than or in line
      with the investment advisory fee rates and overall expenses of the peer
      funds. Based on this review, the Board concluded that the investment
      advisory fees and expense levels and the historical performance of the
      Funds, as managed by Rydex Investments, as compared to the investment
      advisory fees and expense levels and performance of the peer funds, were
      satisfactory for the purposes of approving the continuance of the Advisory
      Agreement.

      COSTS OF SERVICES PROVIDED TO THE FUNDS AND PROFITS REALIZED BY RYDEX
      INVESTMENTS AND ITS AFFILIATES

      The Board reviewed information about the profitability of the Funds to
      Rydex Investments based on the advisory fees payable under the Advisory
      Agreement for the last calendar year. Rydex Investments also presented the
      Board with material discussing its methodology for determining the level
      of advisory fees assessable to the Funds. The Board analyzed the Funds'
      expenses, including the investment advisory fees paid to Rydex
      Investments. The Board also reviewed information regarding direct revenue
      received by Rydex Investments and ancillary revenue received by Rydex
      Investments and/or its affiliates in connection with the services provided
      to the Funds by Rydex Investments (as discussed below) and/or its
      affiliates. The Board also discussed Rydex Investments' profit margin as
      reflected in Rydex Investments' profitability analysis and reviewed
      information regarding economies of scale (as discussed below). Based on
      this review, the Board concluded that the profits to be realized by Rydex
      Investments and its affiliates under the Advisory Agreement and from other
      relationships between the Funds and Rydex Investments and/or its
      affiliates, if any, were within the range the Board considered reasonable
      and appropriate.

      ECONOMIES OF SCALE

      In connection with its review of the Funds' profitability analysis, the
      Board reviewed information regarding economies of scale or other
      efficiencies that may result from increases in the Funds' asset levels.
      The Board noted that the Advisory Agreement for the Funds did not provide
      for any breakpoints in the investment advisory fee rates as a result of
      increases in the asset levels of such Funds. The Board also noted that
      though Rydex Investments' assets under management were significant, the
      amount is spread among more than 95 Funds. Further limiting the
      realization of economies of scale is the ability of shareholders of a
      majority of the Funds to engage in unlimited trading. The Board also
      reviewed Rydex Investments' historic profitability as investment adviser
      to the Funds and determined that reductions in fee rates or additions of
      breakpoints were not warranted at this juncture. Based on this review, the
      Board, recognizing its responsibility to consider this issue at least
      annually, concluded that there are limited economies of scale to share
      with the Funds' shareholders.

      OTHER BENEFITS TO RYDEX INVESTMENTS AND/OR ITS AFFILIATES

      In addition to evaluating the services provided by Rydex Investments, the
      Board also considered the nature, extent, quality and cost of the
      administrative, distribution, and shareholder services performed by Rydex
      Investments' affiliates under separate agreements. The Board noted that
      Rydex Investments reports its use of soft dollars to the Board on a
      quarterly basis, as well as any portfolio transactions on behalf of the
      Funds placed through an affiliate of the Funds or Rydex Investments
      pursuant to Rule 17e-1 under the 1940 Act. Based on its review, the Board
      concluded that the nature and quality of the services provided by Rydex
      Investments' affiliates to the Trust will benefit the Funds' shareholders,
      and that any ancillary benefits would not be disadvantageous to the Funds'
      shareholders, particularly in light of the Board's view that the Funds'
      shareholders benefit from investing in a fund that is part of a large
      family of funds offering a variety of investment strategies and services.

Based on the above analysis, the Board determined that the Advisory Agreement,
including the investment advisory fee rates thereunder, are fair and reasonable
in light of all relevant circumstances and concluded that it is in the best
interest of the Funds and their shareholders to continue the Advisory Agreement.

DEAR SHAREHOLDER:

Financial markets over the six-months ended September 30, 2006, were driven by a
widely anticipated "soft-landing" in the U.S. economy. This "goldilocks"
scenario had economic growth slowing, inflation and interest rates coming down
and the Federal Reserve ("Fed") ending its protracted string of increases. In
this environment, stocks rallied as corporate earnings continued to grow at
double digit rates without competition from higher interest rates. The icing on
the cake was relief from higher energy prices, which had risen relentlessly
since 2005.

While the rally in stocks was fairly broad-based, it definitely exhibited a
defensive bias. Large caps, value stocks and traditionally defensive sectors
generally outperformed small caps, growth stocks and more aggressive sectors.
This pattern is perfectly in keeping with the "late cycle" nature of the stock
market rally. Investors wanted to ride prices up, but wanted to hedge their bets
at the same time.

The large-cap nature of the rally was clearly evident in the performance of the
major averages. The home of the country's industrial giants--the Dow Jones
Industrial Average(SM)--returned 6.34%, followed by the broader S&P 500(R),
which returned 4.14%. If we look at the extremes of the capitalization spectrum,
the large-cap bias becomes more evident as the Russell Top 50(TM) Index returned
7.13% for the six month period versus a loss of 4.61% for the small-cap Russell
2000(R) Index.

In a defensive rally, investors are often wary of overpaying for stocks. That
was certainly true as the Russell 1000(R) Value Index returned 5.5% versus a
0.7% decline for the Russell 1000(R) Growth Index. Although developed market
international stocks did well as the MSCI EAFE Index gained 3.2%, emerging
market stocks fared poorly as the MSCI EM Index fell 1.2%.

A major catalyst for the rally in stocks was the rally in bonds. While yields on
the short end of the curve actually rose, longer dated maturities rallied with
the yield on the benchmark 10-Year Treasury note declining to 4.63% from 4.85%
during the six-month period. The catalyst for falling rates was the decline in
inflation and the Fed's pause from its extended interest rate increases. The
result was a steeply inverted yield curve. Historically, inverted yield curves
presage an economic slowdown or recession. While that remains a possibility, the
decline in long-term rates also signals the market's anticipation of an eventual
easing campaign by the Fed.

The performance of stocks at the sector level highlighted the defensive bias
towards the gains in stock prices over the past six months. The S&P 500
Utilities sector led the way with a gain of 10.2%. Although telecommunications
services, a more aggressive sector, was number two with a gain of 8.1%, consumer
staples and financials were the next best performers, gaining 7.5% and 6.5%,
respectively. It is worth noting that falling interest rates also helped both
financials and utilities. Sectors that typically perform well in a rapidly
expanding economic environment, specifically materials, industrials and
technology declined between 1.0% and 2.3% as the economy slowed.

Going into the fourth quarter, we expect that Gross Domestic Product will pick
up slightly, the Fed will remain on hold and equities will remain range-bound.
As we head into 2007, we also see the appetite for risk continuing to decline.

We appreciate the trust you have placed in our firm by investing with us.

Sincerely,

/s/ David C. Reilly

ABOUT SHAREHOLDERS' FUND EXPENSES (UNAUDITED)
- --------------------------------------------------------------------------------

All mutual funds have operating expenses and it is important for our
shareholders to understand the impact of costs on their investments. As a
shareholder of the fund, you incur two types of costs: (i) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (ii) ongoing costs,
including management fees, administrative services, and shareholder reports,
among others. These ongoing costs, or operating expenses, are deducted from a
fund's gross income and reduce the investment return of the fund.

A fund's expenses are expressed as a percentage of its average net assets, which
is known as the expense ratio. The following examples are intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
The examples are based on an investment of $1,000 made at the beginning of the
period and held for the entire six-month period beginning March 31, 2006 and
ending September 30, 2006.

The following tables illustrate your fund's costs in two ways:

TABLE 1. BASED ON ACTUAL FUND RETURN. This section helps you estimate the actual
   expenses that you paid over the period. The "Ending Account Value" shown is
   derived from the fund's actual return, and the fourth column shows the dollar
   amount that would have been paid by an investor who started with $1,000 in
   the fund. You may use the information here, together with the amount you
   invested, to estimate the expenses that you paid over the period. Simply
   divide your account value by $1,000 (for example, an $8,600 account value
   divided by $1,000 = 8.6), then multiply the result by the number given for
   your fund under the heading "Expenses Paid During Period."

TABLE 2. BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help you
   compare your fund's cost with those of other mutual funds. The table provides
   information about hypothetical account values and hypothetical expenses based
   on the Fund's actual expense ratio and an assumed rate of return of 5% per
   year before expenses, which is not the Fund's actual return. The hypothetical
   account values and expenses may not be used to estimate the actual ending
   account balance or expenses you paid during the period. The example is useful
   in making comparisons because the U.S. Securities and Exchange Commission
   (the "SEC") requires all mutual funds to calculate expenses based on the 5%
   return. You can assess your fund's costs by comparing this hypothetical
   example with the hypothetical examples that appear in shareholder reports of
   other funds.

   Certain retirement plans such as IRA, Roth IRA and 403(b) accounts are
   charged an annual $15 maintenance fee. Upon liquidating your retirement
   account, a $15 account-closing fee will be taken from the proceeds of your
   redemption.

The calculations above assume no shares were bought or sold during the period.
Your actual costs may have been higher or lower, depending on the amount of your
investment and the timing of any purchases or redemptions.

Note that the expenses shown in the table are meant to highlight and help you
compare ongoing costs only and do not reflect any transactional costs which may
be incurred by some of the Fund's classes. These costs may include, but are not
limited to, sales charges (loads), redemption fees, and exchange fees.

You can find more information about the Fund's expenses, including annual
expense ratios for the past five years, in the Financial Highlights section of
this report. For additional information on operating expenses and other
shareholder costs, please refer to the appropriate Fund prospectus.

1. SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the SEC under the
Investment Company Act of 1940 (the "1940 Act") as a non-diversified, open-ended
investment company, and is authorized to issue an unlimited number of no par
value shares. The Trust offers five separate classes of shares, Investor Class
Shares, Advisor Class Shares, A-Class Shares, C-Class Shares, and H-Class
Shares. C-Class Shares have a 1% Contingent Deferred Sales Charge ("CDSC") if
Shares are redeemed within 12 months of purchase. Sales of shares of each Class
are made without a sales charge at the net asset value per share, with the
exception of A-Class Shares. A-Class Shares are sold at net asset value, plus
the applicable front-end sales charge. The sales charge varies depending on the
amount of your purchase, but will not exceed 4.75%.

A-Class Share purchases of $1 million or more have a 1% CDSC if Shares are
redeemed within 18 months of purchase. The current sales charge rates are as
follows:

                                            SALES CHARGE       SALES CHARGE
                                              AS % OF           AS % OF NET

$500,000 but less than
  $1,000,000                                   1.60%               1.63%

At September 30, 2006, the Trust consisted of fifty-three separate series:
twenty-six Benchmark Funds, one Money Market Fund, four Alternative Strategies
Funds, nineteen Sector Funds, and three Essential Portfolio Funds. This report
covers the nineteen Sector Funds (the "Funds"), while the Money Market Fund, the
Benchmark Funds, the Alternative Strategies Funds and the Essential Portfolio
Funds are contained in separate reports. At a meeting on September 25, 2006, the
Board of Trustees approved redemption fees of 1% on redemptions of shares held
for less than 30 days for all share classes of the Commodities Fund. These fees
will be effective on January 1, 2007. For the period October 1, 2006 through
December 31, 2006, shareholders will be restricted to one substantive redemption
out of the Fund followed by a purchase of the Fund during the period.

The following significant accounting policies are in conformity with accounting
principles generally accepted in the United States of America and are
consistently followed by the Trust.

A. Equity securities listed on an exchange (New York Stock Exchange ("NYSE") or
American Stock Exchange) are valued at the last quoted sales price as of close
of business on the NYSE, usually 4:00 p.m., Eastern Time, on the valuation date.
Equity securities listed on the Nasdaq market system are valued at the Nasdaq
Official Closing Price, usually as of 4:00 p.m., Eastern Time, on the valuation
date. Listed options held by the Trust are valued at the Official Settlement
Price listed by the exchange, usually as of 4:00 p.m., Eastern Time.
Over-the-Counter options held by the Trust are valued using the average bid
price obtained from one or more security dealers. The value of futures contracts
purchased and sold by the Trust are accounted for using the unrealized gain or
loss on the contracts that is determined by marking the contracts to their
current realized settlement prices. Financial futures contracts are valued at
the last quoted sales price, usually as of 4:00 p.m., Eastern Time, on the
valuation date. In the event that the exchange for a specific futures contract
closes earlier than 4:00 p.m., Eastern Time, the futures contract is valued at
the Official Settlement Price of the exchange. However, the underlying
securities from which the futures contract value is derived are monitored until
4:00 p.m., Eastern Time, to determine if fair valuation would provide a more
accurate valuation. Short-term securities, if any, are valued at amortized cost,
which approximates market value.

Structured notes are valued in accordance with the terms of their agreement at
the value of the underlying index close, usually 4:00 p.m., Eastern Time,
adjusted for any interest accruals and financing charges. If the securities
comprising the underlying index cease trading before the fund's close of
business, the index will be fair valued with the use of an appropriate market
indicator.

The value of domestic equity index swap agreements entered into by the Funds is
accounted for using the unrealized gain or loss on the agreements that is
determined by marking the agreements to the last quoted value of the index that
the swap pertains to at the close of the NYSE, usually 4:00 p.m., Eastern Time.
The swap's market value is then adjusted to include dividends accrued, financing
charges and/or interest associated with the swap agreements.

The value of foreign equity index, commodity index, and currency index swap
agreements entered into by the Funds are accounted for using the unrealized gain
or loss on the agreements that is determined by marking the agreements to the
price at which orders are being filled at the close of the NYSE, usually 4:00
p.m., Eastern Time. In the event that no order is filled at 4:00 p.m., Eastern
Time, the security dealer provides a fair value quote at which the swap
agreement is valued. The swap's market value is then adjusted to include


74 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

dividends accrued, financing charges and/or interest associated with the swap
agreements.

Investments, including structured notes, for which market quotations are not
readily available are valued at fair value as determined in good faith by Rydex
Investments (the "Advisor"), an affiliated entity, under direction of the Board
of Trustees using methods established or ratified by the Board of Trustees.
These methods include, but are not limited to: (i) general information as to how
these securities and assets trade; (ii) in connection with futures contracts and
options thereupon, and other derivative investments, information as to how (a)
these contracts and other derivative investments trade in the futures or other
derivative markets, respectively, and (b) the securities underlying these
contracts and other derivative investments trade in the cash market; and (iii)
other information and considerations, including current values in related
markets.

B. Securities transactions are recorded on the trade date for financial
reporting purposes. Realized gains and losses from securities transactions are
recorded using the identified cost basis. Proceeds from lawsuits related to
investment holdings are recorded as realized gains in the respective Fund.
Dividend income is recorded on the ex-dividend date, net of applicable taxes
withheld by foreign countries. Interest income, including amortization of
premiums and accretion of discount, is accrued on a daily basis.

C. Distributions of net investment income and net realized capital gains are
recorded on the ex-dividend date. Distributions from net investment income and
net realized capital gains are determined in accordance with income tax
regulations which may differ from accounting principles generally accepted in
the United States of America. These differences are primarily due to differing
treatments for items such as deferral of wash sales and post-October losses and
regulated futures contracts and options. Net investment income and loss, net
realized gains and losses, and net assets are not affected by these differences.

D. The Funds seek capital appreciation and invest substantially all of their
assets in equity securities of companies involved in their sector, with the
exception of the Commodities Fund, which invests primarily in "commodity
related" derivative instruments.

E. Upon the purchase of an option by a Fund, the premium paid is recorded as an
investment, the value of which is marked-to-market daily. When a purchased
option expires, the Fund will realize a loss in the amount of the cost of the
option. When the Fund enters into a closing sale transaction, the Fund will
realize a gain or loss depending on whether the proceeds from the closing sale
transaction are greater or less than the cost of the option. When a Fund
exercises a put option, it will realize a gain or loss from the sale of the
underlying security and the proceeds from such sale will be decreased by the
premium originally paid. When a Fund exercises a call option, the cost of the
security that the Fund purchases upon exercise will be increased by the premium
originally paid. When a Fund writes (sells) an option, an amount equal to the
premium received is entered in the Trust's accounting records as an asset and
equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current value of the option written. When a
written option expires, or if the Fund enters into a closing purchase
transaction, the Fund realizes a gain (or loss if the cost of a closing purchase
transaction exceeds the premium received when the option was sold).

F. The Trust may purchase or sell stock and bond index futures contracts and
options on such futures contracts. Futures contracts are contracts for delayed
delivery of securities at a specified future delivery date and at a specific
price. Upon entering into a contract, a Fund deposits and maintains as
collateral such initial margin as required by the exchange on which the
transaction is effected. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the contract is
closed, the Fund records a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time it
was closed.

G. The Trust may enter into swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified equity security, basket of equity
securities, equity index, commodity index, or U.S. Dollar index, in return for
periodic payments based on a fixed or variable interest rate or the change in
market value of a different equity security, basket of equity securities, equity
index, commodity index, or U.S. Dollar index. Swap agreements are used to obtain
exposure to an equity or market without owning or taking physical custody of
securities. In accordance with a Revenue Ruling issued by the Internal Revenue
Service (the "IRS"), the Trust will not invest in commodity index swaps after
September 30, 2006.

H. The Trust may invest in structured notes, which are over-the-counter
contracts linked to the performance of an underlying benchmark such as interest
rates, equity


                                  THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT | 75



NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

markets, equity indices, commodities indices, corporate credits or foreign
exchange markets. A structured note is a type of bond in which an issuer borrows
money from investors and pays back the principal, adjusted for performance of
the underlying benchmark, at a specified maturity date. In addition, the
contract may require periodic interest payments. Structured notes are used to
obtain exposure to a market without owning or taking physical custody of
securities or commodities.

I. The Funds may also purchase American Depository Receipts, U.S. Government
securities, enter into repurchase agreements, and engage in futures, options and
swap transactions.

J. The Fund may leave Cash in Custodian Bank overnight in its cash account with
the custodian, U.S. Bancorp. Periodically, a Fund may have Cash Payable to
Custodian Bank as an overdraft balance. A fee is incurred on this overdraft,
calculated by multiplying the overdraft by a rate based on the federal funds
rate.

K. Interest and dividend income, most expenses, all realized gains and losses,
and all unrealized gains and losses are allocated to the Classes based upon the
value of the outstanding shares in each Class. Certain costs, such as
distribution fees relating to Advisor Class Shares, A-Class Shares and H-Class
Shares and service and distribution fees related to C-Class Shares, are charged
directly to specific Classes. In addition, certain expenses have been allocated
to the individual Funds in the Trust on a pro rata basis upon the respective
aggregate net asset value of each Fund included in the Trust.

L. The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amount of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from these
estimates.

2. FINANCIAL INSTRUMENTS

As part of its investment strategy, the Trust may utilize a variety of
derivative instruments, including options, futures, options on futures,
structured notes, swap agreements, and short sales. These investments involve,
to varying degrees, elements of market risk and risks in excess of the amounts
recognized in the Statements of Assets and Liabilities.

In the normal course of business, the Funds enter into contracts that contain a
variety of representations and warranties, which provide general
indemnifications. The Funds' maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Funds
and/or its affiliates that have not yet occurred. However, based on experience,
the Funds expect the risk of loss to be remote.

The risk associated with purchasing options is limited to the premium originally
paid. Options written by a Fund involve, to varying degrees, risk of loss in
excess of the option value reflected in the Statements of Assets and
Liabilities. The risk in writing a covered call option is that a Fund may forego
the opportunity for profit if the market price of the underlying security
increases and the option is exercised. The risk in writing a covered put option
is that a Fund may incur a loss if the market price of the underlying security
decreases and the option is exercised. In addition, there is the risk that a
Fund may not be able to enter into a closing transaction because of an illiquid
secondary market or, for over-the-counter options, because of the counterparty's
inability to perform. The Trust has established strict counterparty credit
guidelines and enters into transactions only with financial institutions of
investment grade or better.

There are several risks in connection with the use of futures contracts. Futures
contracts involve, to varying degrees, risk of loss in excess of amounts
reflected in the financial statements. Risks may be caused by an imperfect
correlation between movements in the price of the instruments and the price of
the underlying securities. In addition, there is the risk that a Fund may not be
able to enter into a closing transaction because of an illiquid secondary
market.

There are several risks associated with the use of structured notes. Structured
securities are leveraged, providing an exposure to the underlying benchmark of
three times the face amount and increasing the volatility of each note relative
to the change in the underlying linked financial instrument. A highly liquid
secondary market may not exist for the structured notes a Fund invests in which
may make it difficult for the Fund to sell the structured notes it holds at an
acceptable price or to accurately value them. In addition, structured notes are
subject to the risk that the counterparty to the instrument, or issuer, might
not pay interest when due or repay principal at maturity of the obligation.
Although the Trust will not invest in any structured notes unless the Advisor
believes that the issuer is creditworthy, a Fund does bear the risk of loss of
the amount expected to be received in the event of the default or bankruptcy of
the issuer. The Trust has established strict counterparty credit guidelines and
enters into transactions only with financial institutions of investment grade or
better.

The use of equity swaps involves risks that are different from those associated
with ordinary portfolio securities


76 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

transactions. Swap agreements may be considered to be illiquid. Although the
Trust will not enter into any swap agreement unless the Advisor believes that
the other party to the transaction is creditworthy, a Fund does bear the risk of
loss of the amount expected to be received under a swap agreement in the event
of the default or bankruptcy of the agreement counterparty. The Trust has
established strict counterparty credit guidelines and enters into transactions
only with financial institutions of investment grade or better.

Short sales are transactions in which a Fund sells a security it does not own.
If the security the Fund sold short goes down in price between the time the Fund
sells the security and closes its short position, the Fund will realize a gain
on the transaction. Conversely, if the security goes up in price during the
period, the Fund will realize a loss on the transaction. The risk of such price
increases is the principal risk of engaging in short sales.

In conjunction with the use of options, futures, options on futures, swap
agreements, as well as short sales of securities, the Funds are required to
maintain collateral in various forms. The Funds use, where appropriate,
depending on the financial instrument utilized and the broker involved, margin
deposits at the broker, cash and/or securities segregated at the custodian bank,
discount notes, or the repurchase agreements allocated to each of the Funds.

The risks inherent in the use of options, futures contracts, options on futures
contracts, structured notes, swap agreements, as well as short sales of
securities include i) adverse changes in the value of such instruments; ii)
imperfect correlation between the price of the instruments and movements in the
price of the underlying securities, indices, or futures contracts; iii) the
possible absence of a liquid secondary market for any particular instrument at
any time; and iv) the potential of counterparty default.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of an investment advisory contract, the Trust pays the Advisor,
an affiliated entity, investment advisory fees calculated at an annualized rate
of 0.85% of the average daily net assets of each of the Funds, except the
Precious Metals Fund, which is 0.75% of the average daily net assets. Effective
May 1, 2006, the Advisor has contractually agreed to waive its 0.75% management
fee to the extent necessary to limit the ordinary operating expenses of the
Commodities Fund (but excluding interest expenses, brokerage commissions, and
extraordinary expenses) to not more than 1.20%, 1.95%, and 1.20% per annum of
the average monthly net assets of the A-Class, C-Class, and H-Class of the Fund,
respectively (the "Contractual Fee Waiver"). The Contractual Fee Waiver may not
be modified or eliminated prior to August 1, 2007, except with the approval of
the Board of Trustees. There is no guarantee that the Contractual Fee Waiver
will continue beyond August 1, 2007. Certain officers and trustees of the Trust
are also officers of the Advisor. Rydex Investments, an affiliated entity,
provides transfer agent and administrative services to the Trust for fees
calculated at an annualized rate of 0.25% of the average daily net assets of
each of the Sector Funds.

Rydex Investments also provides accounting services to the Trust calculated at
an annualized rate of 0.10% on the first $250 million of the average daily net
assets, 0.075% on the next $250 million of the average daily net assets, 0.05%
on the next $250 million of the average daily net assets, and 0.03% on the
average daily net assets over $750 million of each of the Sector Funds. Certain
officers and trustees of the Trust are also officers of Rydex Investments.

Rydex Investments also provides other necessary services to the Trust, such as
accounting and auditing services, legal services, printing and mailing, etc., on
a pass-through basis. Such expenses vary from Fund to Fund and are allocated to
the Funds based on relative net assets.

The Trust has adopted a Distribution Plan and Shareholder Services Plan
applicable to its Advisor Class Shares and a Distribution Plan applicable to
A-Class Shares and H-Class Shares for which Rydex Distributors, Inc. (the
"Distributor"), an affiliated entity, and other firms that provide distribution
and/or shareholder services ("Service Providers") may receive compensation. If a
Service Provider provides distribution services, the Trust will pay distribution
fees to the Distributor at an annual rate not to exceed 0.25% of average daily
net assets, pursuant to Rule 12b-1 of the 1940 Act. The Distributor, in turn,
will pay the Service Provider out of its fees. The Distributor may, at its
discretion, retain a portion of such payments to compensate itself for
distribution services. With regard to Advisor Class Shares only, if a Service
Provider provides shareholder services, the Distributor will receive shareholder
servicing fees from the Trust at an annual rate not to exceed 0.25% of average
daily net assets. The Distributor, in turn, will pay the Service Provider out of
its fees.

The Trust has adopted a separate Distribution and Shareholder Services Plan
applicable to its C-Class Shares that allows the Funds to pay annual
distribution and service fees of 1.00% of the Funds' C-Class Shares average

annual 0.75% distribution fee reimburses the Distributor for paying the
shareholder's financial advisor an ongoing sales commission. The Distributor
advances the first year's service and distribution fees to the Financial
Advisor. The Distributor retains the service and distribution fees on accounts
with no authorized dealer of record. Certain officers and trustees of the Trust
are also officers of the Distributor.

4. FEDERAL INCOME TAX INFORMATION

The Funds intend to comply with the provisions of the Internal Revenue Code
applicable to regulated investment companies and will distribute all net
investment income and capital gains to shareholders. Therefore, no Federal
income tax provision is required.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. These differences are primarily due to
differing treatments for derivatives, foreign currency transactions, losses
deferred due to wash sales, losses deferred due to post-October losses, and
excise tax regulations.

Permanent book and tax basis differences, if any, relating to shareholder
distributions will result in reclassifications to paid-in capital. This includes
net operating losses not utilized during the current year, reclasses of swap
related income and gains, and the utilization of earnings and profits
distributed to the shareholders on redemption of shares as part of the dividend
paid deduction for income tax purposes. These reclassifications have no effect
on net assets or net asset values per share. Any taxable gain remaining at
fiscal year end is distributed in the following year.

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN
48). FIN 48 provides guidance for how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax positions not deemed to meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the current year. Adoption of
FIN 48 is required for fiscal years beginning after December 15, 2006 and is to
be applied to all open tax years as of the effective date. At this time,
management is evaluating the implications of FIN 48 and its impact in the
financial statements has not yet been determined.

At September 30, 2006, the cost of securities for Federal income tax purposes,
the aggregate gross unrealized gain for all securities for which there was an
excess of value over tax cost and the aggregate gross unrealized loss for all
securities for which there was an excess of tax cost over value, were as
follows:



                                                          TAX            TAX               NET

5. REPURCHASE AGREEMENTS

The Trust transfers uninvested cash balances into a single joint account, the
daily aggregate balance of which is invested in one or more repurchase
agreements collateralized by obligations of the U.S. Treasury. The collateral is
in the possession of the Trust's custodian and is evaluated daily to ensure that
its market value exceeds by, at a minimum, 102% of the delivery value of the
repurchase agreement at maturity.

The repurchase agreements executed by the joint account and outstanding as of
September 30, 2006, were as follows:



COUNTERPARTY                 TERMS OF AGREEMENT     FACE VALUE   MARKET VALUE   MATURITY VALUE

- ----------------------------------------------------------------------------------------------


As of September 30, 2006, the collateral for the repurchase agreements in the
joint account was as follows:

SECURITY TYPE                RANGE OF RATES          PAR VALUE      MARKET VALUE
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

In the event of counterparty default, the Trust has the right to collect the
collateral to offset losses incurred. There is potential loss to the Trust in
the event the Trust is delayed or prevented from exercising its rights to
dispose of the collateral securities, including the risk of a possible decline
in the value of the underlying securities during the period while the Trust
seeks to assert its rights. The Trust's investment advisor, acting under the
supervision of the Board of Trustees, reviews the value of the collateral and
the credit worthiness of those banks and dealers with which the Trust enters
into repurchase agreements to evaluate potential risks.

6. SECURITIES TRANSACTIONS

During the period ended September 30, 2006, purchases and sales of investment

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

8. PORTFOLIO SECURITIES LOANED

The Trust lends its securities to approved brokers to earn additional income.
Security lending income shown on the statement of operations is shown net of
rebates paid to borrowers and earnings on cash collateral investments shared
with the lending agent. Within this arrangement, the Trust acts as the lender,
U.S. Bancorp acts as the agent, and other approved registered broker dealers act
as the borrowers. The Trust receives cash collateral, valued at 100% of the
value of the securities on loan, which is initially held in a segregated account
at U.S. Bancorp. As agent, U.S. Bancorp may, for investment purposes, pool the
Trust's collateral in joint accounts with cash collateral from one or more other
securities lending customers of U.S. Bancorp. Under the terms of the Trust's
securities lending agreement with U.S. Bancorp, cash collateral may be invested
by U.S. Bancorp in certain high quality, liquid investments. At September 30,
2006, the pooled cash collateral investments consisted of repurchase agreements
(46.60%), commercial paper (34.12%), fixed income securities (15.48%),
guaranteed investment contract (3.67%), and mutual funds (0.13%). Collateral is
maintained over the life of the loan in an amount not less than the value of
loaned securities, as determined at the close of fund business each day; any
additional collateral required due to changes in security values is delivered to
the Fund the next business day. Although the collateral mitigates risk, the
Trust could experience a delay in recovering its securities and a possible loss
of income or value if the borrower fails to return the securities. The Trust has
the right under the securities lending agreement to recover the securities from
the borrower on demand.

The following represents a breakdown of the collateral, its rates, and
maturities:



COLLATERAL TYPE                                               RATES                     MATURITY

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONCLUDED)

9. CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board has selected Ernst & Young LLP (E&Y) to serve as the Funds'
independent registered public accounting firm for the fiscal year ended March
31, 2007. The decision to select E&Y was recommended by the Audit Committee and
was approved by the Board on September 25, 2006. During the Funds' fiscal years
ended March 31, 2006 and March 31, 2005, none of the Funds, their portfolios nor
anyone on their behalf consulted with E&Y on items which (i) concerned the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Funds' financial statements; or (ii) concerned the subject of a disagreement
(as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable
events (as described in paragraph (a)(1)(iv) of said Item 304).

The selection of E&Y does not reflect any disagreements with or dissatisfaction
by the Funds or the Board with the performance of the Funds' prior auditor,
PricewaterhouseCoopers LLP (PwC). The decision to dismiss PwC effective upon its
completion of its audits for the fiscal year ended March 31, 2006 and to select
E&Y was recommended by the Funds' Audit Committee and approved by the Funds'
Board of Trustees. PwC's report on the Funds' financial statements for the
fiscal years ended March 31, 2006 and 2005 contained no adverse opinion or
disclaimer of opinion nor were they qualified or modified as to uncertainty,
audit scope or accounting principles. During the Funds' fiscal years ended March
31, 2006 and March 31, 2005, (i) there were no disagreements with PwC on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedure, which disagreements, if not resolved to the
satisfaction of PwC, would have caused it to make reference to the subject
matter of the disagreements in connection with its report on the Funds'
financial statements for such years, and (ii) there were no "reportable events"
of the kind described in Item 304(a)(1)(v) of Regulation SK under the Securities
and Exchange Act of 1934, as amended.

RYDEX INVESTMENTS BOARD REVIEW AND APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

The Investment Company Act of 1940 (the "1940 Act") requires that the initial
approval of, as well as the continuation of, a fund's investment advisory
agreement be specifically approved (1) by the vote of the trustees or by a vote
of the shareholders of the fund, and (2) by the vote of a majority of the
trustees who are not parties to the investment advisory agreement or "interested
persons" of any party (the "Independent Trustees"), cast in person at a meeting
called for the purpose of voting on such approval. In connection with such
approvals, the fund's trustees must request and evaluate, and the investment
adviser is required to furnish, such information as may be reasonably necessary
to evaluate the terms of the advisory agreement. In addition, the Securities and
Exchange Commission (the "SEC") takes the position that, as part of their
fiduciary duties with respect to fund fees, fund boards are required to evaluate
the material factors applicable to a decision to approve an investment advisory
agreement.

Consistent with these responsibilities, the Rydex Series Funds Board of Trustees
(the "Board") calls and holds one meeting each year that is dedicated to
considering whether to renew the investment advisory agreement between Rydex
Series Funds (the "Trust") and PADCO Advisors, Inc., which does business under
the name Rydex Investments ("Rydex Investments"), (the "Advisory Agreement")
with respect to existing funds in the Trust, including the funds discussed in
this Semi-Annual Report (each a "Fund" and collectively, the "Funds"), and to
reviewing certain other agreements pursuant to which Rydex Investments provides
investment advisory services to certain other registered investment companies.
In preparation for the meeting, the Board requests and reviews a wide variety of
materials provided by Rydex Investments, including information about Rydex
Investments' affiliates, personnel and operations. The Board also receives data
provided by third parties. This information is in addition to the detailed
information about the Funds that the Board reviews during the course of each
year, including information that relates to Fund operations and performance. The
Board also receives a memorandum from Fund counsel regarding the
responsibilities of the Board for the approval of investment advisory
agreements. In addition, the Independent Trustees receive advice from
independent counsel to the Independent Trustees, meet in executive session
outside the presence of fund management, and participate in question and answer
sessions with representatives of Rydex Investments.

At a meeting held on August 27 and 28, 2006, the Board approved the selection of
Rydex Investments and the continuance of the Advisory Agreement for an
additional one-year period, based on its review of qualitative and quantitative
information provided by Rydex Investments. The Board's approval of the Advisory
Agreement was based on consideration and evaluation of a variety of specific
factors discussed at that meeting and at prior meetings, including:

      NATURE, EXTENT AND QUALITY OF SERVICES PROVIDED BY RYDEX INVESTMENTS

      The Board reviewed the scope of services to be provided by Rydex
      Investments under the Advisory Agreement and noted that there would be no
      significant differences between the scope of services required to be
      provided by Rydex Investments for the past year and the scope of services
      required to be provided by Rydex Investments for the upcoming year. In
      reviewing the scope of services provided to the Funds by Rydex
      Investments, the Board reviewed and discussed Rydex Investments'
      investment experience, noting that Rydex Investments and its affiliates
      have committed significant resources over time to the support of the
      Funds. The Board also considered Rydex Investments' compliance program and
      its compliance record with respect to the Funds. In that regard, the Board
      noted that Rydex Investments provides information regarding the portfolio
      management and compliance to the Board on a periodic basis in connection
      with regularly scheduled meetings of the Board. In addition to the above
      considerations, the Board reviewed and considered

OTHER INFORMATION (UNAUDITED) (CONTINUED)
- -------------------------------------------------------------------------------

      Rydex Investments' investment processes and strategies, and matters
      related to Rydex Investments' portfolio transaction policies and
      procedures. In particular, the Board noted the substantial volume of
      portfolio trades and shareholder transaction activity, in general,
      processed by Rydex Investments due to the unlimited exchange policy of the
      majority of the Funds. The Board further noted that the Funds have met
      their investment objectives consistently since their relevant inception
      dates. Based on this review, the Board concluded that the nature, extent
      and quality of services to be provided by Rydex Investments to the Funds
      under the Advisory Agreement were appropriate and continued to support the
      Board's original selection of Rydex Investments as investment adviser to
      the Funds.

      FUND EXPENSES AND PERFORMANCE OF THE FUNDS AND RYDEX INVESTMENTS

      The Board reviewed statistical information prepared by Rydex Investments
      regarding the expense ratio components, including actual advisory fees,
      waivers/reimbursements, and gross and net total expenses of each Fund in
      comparison with the same information for other funds registered under the
      1940 Act determined by Rydex Investments to comprise each Fund's
      applicable peer group. Because few funds seek to provide unlimited
      exchange privileges similar to those of the Funds (other than the
      Commodities Fund, Multi-Cap Core Equity Fund, Sector Rotation Fund,
      Absolute Return Strategies Fund, and Hedged Equity Fund), each Fund's
      applicable peer group is generally limited to the funds of two
      unaffiliated mutual fund families. In addition, the Board reviewed
      statistical information prepared by Rydex Investments relating to the
      performance of each Fund, as well as each Fund's ability to successfully
      track its benchmark over time, and a comparison of each Fund's performance
      to funds with similar investment objectives for the same periods and to
      appropriate indices/benchmarks, in light of total return, yield and market
      trends. The Board further noted that despite the unique nature of the
      Funds, the peer fund information presented to the Board was meaningful
      because the peer funds' investment objectives and strategies were closely
      aligned with those of the Funds. The Board noted that most of the Funds
      either outperformed their peer funds or performed in line with them over
      relevant periods. The Board also noted that the investment advisory fees
      and overall expenses for the Funds were generally lower than or in line
      with the investment advisory fee rates and overall expenses of the peer
      funds. Based on this review, the Board concluded that the investment
      advisory fees and expense levels and the historical performance of the
      Funds, as managed by Rydex Investments, as compared to the investment
      advisory fees and expense levels and performance of the peer funds, were
      satisfactory for the purposes of approving the continuance of the Advisory
      Agreement.

      COSTS OF SERVICES PROVIDED TO THE FUNDS AND PROFITS REALIZED BY RYDEX
      INVESTMENTS AND ITS AFFILIATES

      The Board reviewed information about the profitability of the Funds to
      Rydex Investments based on the advisory fees payable under the Advisory
      Agreement for the last calendar year. Rydex Investments also presented the
      Board with material discussing its methodology for determining the level
      of advisory fees assessable to the Funds. The Board analyzed the Funds'
      expenses, including the investment advisory fees paid to Rydex
      Investments. The Board also reviewed information regarding direct revenue
      received by Rydex Investments and ancillary revenue received by Rydex
      Investments and/or its affiliates in connection with the services provided
      to the Funds by Rydex Investments (as discussed below) and/or its
      affiliates. The Board also discussed Rydex Investments' profit margin as
      reflected in Rydex Investments' profitability analysis and reviewed
      information regarding economies of scale (as discussed below). Based on
      this review, the Board concluded that the profits to be realized by Rydex
      Investments and its affiliates under the Advisory Agreement and from other
      relationships between the Funds and Rydex Investments and/or its
      affiliates, if any, were within the range the Board considered reasonable
      and appropriate.

      ECONOMIES OF SCALE

      In connection with its review of the Funds' profitability analysis, the
      Board reviewed information regarding economies of scale or other
      efficiencies that may result from increases in the Funds' asset levels.
      The Board noted that the Advisory Agreement for the Funds did not provide
      for any breakpoints in the investment advisory fee rates as a result of
      increases in the asset levels of such Funds. The Board also noted that
      though Rydex Investments' assets under management were significant, the
      amount is spread among more than 95 Funds. Further limiting the
      realization of economies of scale is the ability of shareholders of a
      majority of the Funds to engage in unlimited trading. The Board also
      reviewed Rydex Investments' historic profitability as investment adviser
      to the Funds and determined that reductions in fee rates or additions of
      breakpoints were not warranted at this juncture. Based on this review, the
      Board, recognizing its responsibility to consider this issue at least
      annually, concluded that there are limited economies of scale to share
      with the Funds' shareholders.

OTHER INFORMATION (UNAUDITED) (CONCLUDED)
- --------------------------------------------------------------------------------

      OTHER BENEFITS TO RYDEX INVESTMENTS AND/OR ITS AFFILIATES

      In addition to evaluating the services provided by Rydex Investments, the
      Board also considered the nature, extent, quality and cost of the
      administrative, distribution, and shareholder services performed by Rydex
      Investments' affiliates under separate agreements. The Board noted that
      Rydex Investments reports its use of soft dollars to the Board on a
      quarterly basis, as well as any portfolio transactions on behalf of the
      Funds placed through an affiliate of the Funds or Rydex Investments
      pursuant to Rule 17e-1 under the 1940 Act. Based on its review, the Board
      concluded that the nature and quality of the services provided by Rydex
      Investments' affiliates to the Trust will benefit the Funds' shareholders,
      and that any ancillary benefits would not be disadvantageous to the Funds'
      shareholders, particularly in light of the Board's view that the Funds'
      shareholders benefit from investing in a fund that is part of a large
      family of funds offering a variety of investment strategies and services.

Based on the above analysis, the Board determined that the Advisory Agreement,
including the investment advisory fee rates thereunder, are fair and reasonable
in light of all relevant circumstances and concluded that it is in the best
interest of the Funds and their shareholders to continue the Advisory Agreement.

LETTER TO OUR SHAREHOLDERS
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

Financial markets over the six-months ended September 30, 2006, were driven by a
widely anticipated "soft-landing" in the U.S. economy. This "goldilocks"
scenario had economic growth slowing, inflation and interest rates coming down
and the Federal Reserve ("Fed") ending its protracted string of increases. In
this environment, stocks rallied as corporate earnings continued to grow at
double digit rates without competition from higher interest rates. The icing on
the cake was relief from higher energy prices, which had risen relentlessly
since 2005.

While the rally in stocks was fairly broad-based, it definitely exhibited a
defensive bias. Large caps, value stocks and traditionally defensive sectors
generally outperformed small caps, growth stocks and more aggressive sectors.
This pattern is perfectly in keeping with the "late cycle" nature of the stock
market rally. Investors wanted to ride prices up, but wanted to hedge their bets
at the same time.

The large-cap nature of the rally was clearly evident in the performance of the
major averages. The home of the country's industrial giants--the Dow Jones
Industrial Average(SM)--returned 6.34%, followed by the broader S&P 500(R)
Index, which returned 4.14%. If we look at the extremes of the capitalization
spectrum, the large-cap bias becomes more evident as the Russell Top 50(TM)
Index returned 7.13% for the six month period versus a LOSS of 4.61% for the
small-cap Russell 2000(R) Index.

In a defensive rally, investors are often wary of overpaying for stocks. That
was certainly true as the Russell 1000(R) Value Index returned 5.5% versus a
0.7% decline for the Russell 1000(R) Growth Index. Although developed market
international stocks did well as the MSCI EAFE Index gained 3.2%, emerging
market stocks fared poorly as the MSCI EM Index fell 1.2%.

A major catalyst for the rally in stocks was the rally in bonds. While yields on
the short end of the curve actually rose, longer dated maturities rallied with
the yield on the benchmark 10-Year Treasury note declining to 4.63% from 4.85%
during the six-month period. The catalyst for falling rates was the decline in
inflation and the Fed's pause from its extended interest rate increases. The
result was a steeply inverted yield curve. Historically, inverted yield curves
presage an economic slowdown or recession. While that remains a possibility, the
decline in long-term rates also signals the market's anticipation of an eventual
easing campaign by the Fed.

The performance of stocks at the sector level highlighted the defensive bias
towards the gains in stock prices over the past six months. The S&P 500
Utilities sector led the way with a gain of 10.2%. Although telecommunications
services, a more aggressive sector, was number two with a gain of 8.1%, consumer
staples and financials were the next best performers, gaining 7.5% and 6.5%,
respectively. It is worth noting that falling interest rates also helped both
financials and utilities. Sectors that typically perform well in a rapidly
expanding economic environment, specifically materials, industrials and
technology declined between 1.0% and 2.3% as the economy slowed.

Going into the fourth quarter, we expect that Gross Domestic Product will pick
up slightly, the Fed will remain on hold and equities will remain range-bound.
As we head into 2007, we also see the appetite for risk continuing to decline.

We appreciate the trust you have placed in our firm by investing with us.

Sincerely,

/s/ David C. Reilly

David C. Reilly, CFA
Director of Investment Strategy

ABOUT SHAREHOLDERS' FUND EXPENSES (UNAUDITED)
- --------------------------------------------------------------------------------

All mutual funds have operating expenses and it is important for our
shareholders to understand the impact of costs on their investments. As a
shareholder of the fund, you incur two types of costs: (i) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (ii) ongoing costs,
including management fees, administrative services, and shareholder reports,
among others. These ongoing costs, or operating expenses, are deducted from a
fund's gross income and reduce the investment return of the fund.

A fund's expenses are expressed as a percentage of its average net assets, which
is known as the expense ratio. The following examples are intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
The examples are based on an investment of $1,000 made at the beginning of the
period and held for the entire six-month period beginning March 31, 2006 and
ending September 30, 2006.

The following tables illustrate your fund's costs in two ways:

TABLE 1. BASED ON ACTUAL FUND RETURN. This section helps you estimate the actual
      expenses that you paid over the period. The "Ending Account Value" shown
      is derived from the Fund's actual return, and the fourth column shows the
      dollar amount that would have been paid by an investor who started with
      $1,000 in the Fund. You may use the information here, together with the
      amount you invested, to estimate the expenses that you paid over the
      period. Simply divide your account value by $1,000 (for example, an $8,600
      account value divided by $1,000 = 8.6), then multiply the result by the
      number given for your fund under the heading "Expenses Paid During
      Period."

TABLE 2. BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help you
      compare your fund's cost with those of other mutual funds. The table
      provides information about hypothetical account values and hypothetical
      expenses based on the Fund's actual expense ratio and an assumed rate of
      return of 5% per year before expenses, which is not the Fund's actual
      return. The hypothetical account values and expenses may not be used to
      estimate the actual ending account balance or expenses you paid during the
      period. The example is useful in making comparisons because the U.S.
      Securities and Exchange Commission (the "SEC") requires all mutual funds
      to calculate expenses based on the 5% return. You can assess your fund's
      costs by comparing this hypothetical example with the hypothetical
      examples that appear in shareholder reports of other funds.

      Certain retirement plans such as IRA, Roth IRA and 403(b) accounts are
      charged an annual $15 maintenance fee. Upon liquidating your retirement
      account, a $15 account-closing fee will be taken from the proceeds of your
      redemption.

The calculations above assume no shares were bought or sold during the period.
Your actual costs may have been higher or lower, depending on the amount of your
investment and the timing of any purchases or redemptions.

Note that the expenses shown in the table are meant to highlight and help you
compare ongoing costs only and do not reflect any transactional costs which may
be incurred by some of the Fund's classes. These costs may include, but are not
limited to, sales charges (loads), redemption fees, and exchange fees.

You can find more information about the Fund's expenses, including annual
expense ratios for the past five years, in the Financial Highlights section of
this report. For additional information on operating expenses and other
shareholder costs, please refer to the appropriate Fund prospectus.

1. SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the SEC under the
Investment Company Act of 1940 (the "1940 Act") as a non-diversified, open-ended
investment company, and is authorized to issue an unlimited number of no par
value shares. The Trust offers five separate classes of shares, Investor Class
Shares, Advisor Class Shares, A-Class Shares, C-Class Shares, and H-Class
Shares. C-Class Shares have a 1% Contingent Deferred Sales Charge ("CDSC") if
Shares are redeemed within 12 months of purchase. Sales of shares of each Class
are made without a sales charge at the net asset value per share, with the
exception of A-Class Shares. A-Class Shares are sold at net asset value, plus
the applicable front-end sales charge. The sales charge varies depending on the
amount of your purchase, but will not exceed 4.75%. A-Class Share purchases of
$1 million or more have a 1% CDSC if Shares are redeemed within 18 months of
purchase. The current sales charge rates are as follows:

                                            SALES CHARGE       SALES CHARGE
                                               AS % OF          AS % OF NET

Less than $100,000                             4.75%               4.99%
$100,000 but less than
  $250,000                                     3.75%               3.90%
$250,000 but less than
  $500,000                                     2.75%               2.83%
$500,000 but less than
  $1,000,000                                   1.60%               1.63%
$1,000,000 or greater                          0.00%               0.00%

At September 30, 2006, the Trust consisted of fifty-three separate series:
twenty-six Benchmark Funds, one Money Market Fund, nineteen Sector Funds, four
Alternative Strategy Funds and three Essential Portfolio Funds. This report
covers the Alternative Strategy Funds (the "Funds"), while the Money Market
Fund, the Benchmark Funds, the Sector Funds and the Essential Portfolio Funds
are contained in separate reports. As of September 30, 2006, only A-Class,
C-Class and H-Class Shares had been issued in the Alternative Strategy Funds.
All share classes of the Absolute Return Strategies Fund and the Hedged Equity
Fund are subject to a 1% redemption fee when shares are redeemed after being
held for less than 30 days. At a meeting on September 25, 2006, the Board of
Trustees approved redemption fees of 1% on redemptions of shares held for less
than 30 days for all share classes of the Multi-Cap Core Equity Fund and the
Sector Rotation Fund. These fees will be effective on January 1, 2007. For the
period October 1, 2006 through December 31, 2006, shareholders will be
restricted to one substantive redemption out of the Fund followed by a purchase
of the Fund during the period.

The following significant accounting policies are in conformity with accounting
principles generally accepted in the United States of America and are
consistently followed by the Trust.

A. Equity securities listed on an exchange (New York Stock Exchange ("NYSE") or
American Stock Exchange) are valued at the last quoted sales price as of close
of business on the NYSE, usually 4:00 p.m., Eastern Time, on the valuation date.
Equity securities listed on the NASDAQ market system are valued at the NASDAQ
Official Closing Price, usually as of 4:00 p.m., Eastern Time, on the valuation
date. Listed options held by the Trust are valued at the Official Settlement
Price listed by the exchange, usually as of 4:00 p.m., Eastern Time. In the
event that a settlement price is not available, fair valuation is enacted.
Over-the-counter options held by the Trust are valued using the average bid
price obtained from one or more security dealers. The value of futures contracts
purchased and sold by the Trust are accounted for using the unrealized gain or
loss on the contracts that is determined by marking the contracts to their
current realized settlement prices. Financial futures contracts are valued at
the last quoted sales price, usually as of 4:00 p.m., Eastern Time, on the
valuation date. In the event that the exchange for a specific futures contract
closes earlier than 4:00 p.m., Eastern Time, the futures contract is valued at
the Official Settlement Price of the exchange. However, the underlying
securities from which the futures contract value is derived are monitored until
4:00 p.m., Eastern Time, to determine if fair valuation would provide a more
accurate valuation. Short-term securities, if any, are valued at amortized cost,
which approximates market value.

The value of domestic equity index and credit default swap agreements entered
into by the Funds is accounted for using the unrealized gain or loss on the
agreements that is determined by marking the agreements to the last quoted value
of the index that the swap pertains to at the close of the NYSE, usally 4:00
p.m., Eastern Time. The swap's market value is then adjusted to include
dividends accrued, financing charges and/or interest associated with the swap
agreements.

Investments for which market quotations are not readily available, are valued at
fair value as determined in good faith by Rydex Investments (the "Advisor")
under direction of the Board of Trustees using methods established or ratified
by the Board of Trustees. These methods include, but are not limited to: (i)
general information as to how these securities and assets trade; (ii) in
connection with futures contracts and options thereupon, and other derivative
investments, information as to how (a) these contracts and other derivative
investments trade in the futures or other derivative markets, respectively, and


42 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

(b) the securities underlying these contracts and other derivative investments
trade in the cash market; and (iii) other information and considerations,
including current values in related-markets.

B. Securities transactions are recorded on the trade date for financial
reporting purposes. Realized gains and losses from securities transactions are
recorded using the identified cost basis. Proceeds from lawsuits related to
investment holdings are recorded as realized gains in the respective Fund.
Dividend income is recorded on the ex-dividend date, net of applicable taxes
withheld by foreign countries. Interest income, including amortization of
premiums and accretion of discount, is accrued on a daily basis.

C. Interest and dividend income, most expenses, all realized gains and losses,
and all unrealized gains and losses are allocated to the Classes based upon the
value of the outstanding shares in each Class. Certain costs, such as
distribution fees relating to A-Class Shares and H-Class Shares and service and
distribution fees related to C-Class Shares, are charged directly to specific
Classes. In addition, certain expenses have been allocated to the individual
Funds in the Trust on a pro rata basis upon the respective aggregate net asset
value of each Fund included in the Trust.

D. Distributions of net investment income and net realized capital gains are
recorded on the ex-dividend date and are determined in accordance with income
tax regulations which may differ from accounting principles generally accepted
in the United States of America. These differences are primarily due to
differing treatments for items such as deferral of wash sales and post-October
losses and regulated futures contracts and options. Net investment income and
loss, net realized gains and losses, and net assets are not affected by these
differences.

E. When a Fund engages in short sales, an amount equal to the proceeds is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked-to-market to reflect the market value of the short sale.
A segregated account of cash and/or securities is maintained as collateral for
short sales. The Funds are exposed to market risk based on the amount, if any,
that the market value of the security exceeds the market value of the securities
in the segregated account. Fees, if any, paid to brokers to borrow securities in
connection with short sales are considered part of the cost of short sale
transactions. In addition, the Funds must pay out the dividend rate of the
equity or coupon rate of the treasury obligation to the purchaser and record
this as an expense. Short Dividends or Interest Expense is a cost associated
with the investment objective of short sales transactions, rather than an
operational cost associated with the day-to-day management of any mutual fund.

F. Upon the purchase of an option by a Fund, the premium paid is recorded as an
investment, the value of which is marked-to-market daily. When a purchased
option expires, the Fund will realize a loss in the amount of the cost of the
option. When the Fund enters into a closing sale transaction, the Fund will
realize a gain or loss depending on whether the proceeds from the closing sale
transaction are greater or less than the cost of the option. When a Fund
exercises a put option, it will realize a gain or loss from the sale of the
underlying security and the proceeds from such sale will be decreased by the
premium originally paid. When a Fund exercises a call option, the cost of the
security that the Fund purchases upon exercise will be increased by the premium
originally paid. When a Fund writes (sells) an option, an amount equal to the
premium received is entered in the Trust's accounting records as an asset and
equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current value of the option written. When a
written option expires, or if the Fund enters into a closing purchase
transaction, the Fund realizes a gain (or loss if the cost of a closing purchase
transaction exceeds the premium received when the option was sold).

G. The Trust may purchase or sell stock and bond index futures contracts and
options on such futures contracts. Futures contracts are contracts for delayed
delivery of securities at a specified future delivery date and at a specific
price. Upon entering into a contract, a Fund deposits and maintains as
collateral such initial margin as required by the exchange on which the
transaction is effected. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the contract is
closed, the Fund records a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time it
was closed.

H. The Trust may enter into swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified equity security, basket of equity
securities, or equity index in return for periodic payments based on a fixed or
variable interest rate or the change in market value of a different equity
security, basket of equity securities, or equity index. Swap agreements are used
to obtain exposure to an equity or market without owning or taking physical
custody of securities.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

I. The Funds seek long-term capital appreciation and respond to the dynamically
changing economy by moving their investments among different sectors or
industries. The Funds may also purchase American Depository Receipts, U.S.
Government securities, enter into repurchase agreements, and engage in futures,
options and swap transactions.

J. The Funds may leave cash overnight in their cash account with the custodian,
U.S. Bancorp. Periodically, a Fund may have cash due to custodian bank as an
overdraft balance. A fee is incurred on this overdraft, calculated by
multiplying the overdraft by a rate based on the federal funds rate. Segregated
cash with the broker is held as collateral for investments in derivative
instruments such as futures contracts and equity index swap agreements.

K. Certain U.S. Government and Agency Obligations are traded on a discount
basis; the interest rates shown on the Schedules of Investments reflect the
discount rates paid at the time of purchase by the Funds. Other securities bear
interest at the rates shown, payable at fixed dates through maturity.

L. The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amount of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from these
estimates.

2. FINANCIAL INSTRUMENTS

As part of its investment strategy, the Trust may utilize a variety of
derivative instruments, including options, futures, options on futures, and swap
agreements. These investments involve, to varying degrees, elements of market
risk and risks in excess of the amounts recognized in the Statements of Assets
and Liabilities.

In the normal course of business, the Funds enter into contracts that contain a
variety of representations and warranties, which provide general
indemnifications. The Funds' maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Funds
and/or its affiliates that have not yet occurred. However, based on experience,
the Funds expect the risk of loss to be remote.

The risk associated with purchasing options is limited to the premium originally
paid. Options written by a Fund involve, to varying degrees, risk of loss in
excess of the option value reflected in the Statements of Assets and
Liabilities. The risk in writing a covered call option is that a Fund may forego
the opportunity for profit if the market price of the underlying security
increases and the option is exercised. The risk in writing a covered put option
is that a Fund may incur a loss if the market price of the underlying security
decreases and the option is exercised. In addition, there is the risk that a
Fund may not be able to enter into a closing transaction because of an illiquid
secondary market or, for over-the-counter options, because of the counterparty's
inability to perform. The Trust has established strict counterparty credit
guidelines and enters into transactions only with financial institutions of
investment grade or better.

There are several risks in connection with the use of futures contracts. Futures
contracts involve, to varying degrees, risk of loss in excess of amounts
reflected in the financial statements. Risks may be caused by an imperfect
correlation between movements in the price of the instruments and the price of
the underlying securities. In addition, there is the risk that a Fund may not be
able to enter into a closing transaction because of an illiquid secondary
market.

The use of swaps involves risks that are different from those associated with
ordinary portfolio securities transactions. Swap agreements may be considered to
be illiquid. Although the Trust will not enter into any swap agreement unless
the Advisor believes that the other party to the transaction is creditworthy,
the Funds bear the risk of loss of the amount expected to be received under a
swap agreement in the event of the default or bankruptcy of the agreement
counterparty. The Trust has established strict counterparty credit guidelines
and enters into transactions only with financial institutions of investment
grade or better.

Short sales are transactions in which a Fund sells a security it does not own.
If the security the Fund sold short goes down in price between the time the Fund
sells the security and closes its short position, the Fund will realize a gain
on the transaction. Conversely, if the security goes up in price during the
period, the Fund will realize a loss on the transaction. The risk of such price
increases is the principal risk of engaging in short sales.

In conjunction with the use of options, futures, options on futures, swap
agreements, as well as short sales of securities, the Funds are required to
maintain collateral in various forms. The Funds use, where appropriate,
depending on the financial instrument utilized and the broker involved, margin
deposits at the broker, cash and/or securities segregated at the custodian bank,
discount notes, or the repurchase agreements allocated to each Fund.

The risks inherent in the use of options, futures contracts, options on futures
contracts, swap agreements, as well as short sales of securities include i)
adverse


44 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

changes in the value of such instruments; ii) imperfect correlation between the
price of the instruments and movements in the price of the underlying
securities, indices, or futures contracts; iii) the possible absence of a liquid
secondary market for any particular instrument at any time; and iv) the
potential of counterparty default.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of an investment advisory contract, the Trust pays the Advisor,
an affiliated entity, investment advisory fees calculated at an annualized rate
of 0.90% of the average daily net assets of the Sector Rotation Fund and 1.15%
of the average daily net assets of the Absolute Return Strategies Fund and the
Hedged Equity Fund. As part of its agreement with the Trust, the Advisor will
pay all expenses of the Absolute Return Strategies Fund and Hedged Equity Fund,
including the cost of transfer agency, custody, fund administration, legal,
audit and other services, except interest expense, taxes (expected to be de
minimis), brokerage commissions and other expenses connected with execution of
portfolio transactions, short dividend expenses, and extraordinary expenses.

Also under the terms of the investment advisory contract, the Trustees voted to
implement a performance adjustment for the Multi-Cap Core Equity Fund. The Trust
pays the Advisor investment advisory fees calculated at a basic annual fee rate
of 0.70% of the average daily net assets of this Fund, adding or subtracting a
performance rate up to 0.20%. The basic annual fee rate, along with the
performance adjustment allows the total fee to increase to a maximum of 0.90% or
decrease to a minimum of 0.50%, depending on the investment performance of the
Fund relative to the Russell 3000 Index (the "Index"). The performance
comparison will be made for a rolling 12-month period, with performance
adjustments made at the end of each month. Because the performance adjustment is
applied relative to the performance of the Index, the Advisor could receive a
positive performance adjustment even during periods where the Fund's performance
is negative. At September 30, 2006, the effective management fee was 0.50% of
the Fund's average daily net assets. Certain officers and trustees of the Trust
are also officers of the Advisor.

Rydex Investments, an affiliated entity, provides transfer agent and
administrative services to the Multi-Cap Core Equity Fund and Sector Rotation
Fund for fees calculated at an annualized rate of 0.25% of the average daily net
assets of these Funds. The Servicer also provides transfer agent and
administrative services to the Absolute Return Strategies Fund and the Hedged
Equity Fund, however the related fees are paid by the Advisor as noted above.

Rydex Investments provides accounting services to the Multi-Cap Core Equity Fund
and Sector Rotation Fund calculated at an annualized rate of 0.10% on the first
$250 million of the average daily net assets, 0.075% on the next $250 million of
the average daily net assets, 0.05% on the next $250 million of the average
daily net assets, and 0.03% on the average daily net assets over $750 million of
these Funds. Rydex Investments also provides accounting services to the Absolute
Return Strategies Fund and the Hedged Equity Fund, however the related fees are
paid by the Advisor, as noted above. Certain officers and trustees of the Trust
are also officers of Rydex Investments.

Rydex Investments also provides other necessary services to the Trust, such as
accounting and auditing services, legal services, printing and mailing, etc., on
a passthrough basis. Such expenses vary from Fund to Fund and are allocated to
the Funds based on relative net assets. Any of these expenses allocated to the
Absolute Return Strategies Fund and the Hedged Equity Fund are paid by the
Advisor, as noted above. Organizational and setup costs for new funds are paid
by the Trust.

The Trust has adopted a Distribution Plan applicable to its A-Class Shares and
H-Class Shares for which Rydex Distributors, Inc. (the "Distributor"), an
affiliated entity, and other firms that provide distribution and/or shareholder
services ("Service Providers") may receive compensation. If a Service Provider
provides distribution services, the Trust will pay distribution fees to the
Distributor at an annual rate not to exceed 0.25% of average daily net assets,
pursuant to Rule 12b-1 of the 1940 Act. The Distributor, in turn, will pay the
Service Provider out of its fees.

The Trust has adopted a separate Distribution and Shareholder Services Plan
applicable to its C-Class Shares that allows the Funds to pay annual
distribution and service fees of 1.00% of the Funds' C-Class Shares average
daily net assets. The annual 0.25% service fee compensates the shareholder's
financial advisor for providing ongoing services to the shareholder. The annual
0.75% distribution fee reimburses the Distributor for paying the shareholder's
financial advisor an on-going sales commission. The Distributor advances the
first year's service and distribution fees to the Financial Advisor. The
Distributor retains the service and distribution fees on accounts with no
authorized dealer of record. Certain officers and trustees of the Trust are also
officers of the Distributor.

4. FEDERAL INCOME TAX INFORMATION

The Funds intend to comply with the provisions of the Internal Revenue Code
applicable to regulated investment companies and will distribute all net
investment income and capital gains to shareholders. Therefore, no Federal
income tax provision is required.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. These differences are primarily due to
differing treatments for derivatives, foreign currency transactions, losses
deferred due to wash sales, losses deferred due to post-October losses, and
excise tax regulations.

Permanent book and tax basis differences, if any, relating to shareholder
distributions will result in reclassifications to paid-in capital. This includes
net operating losses not utilized during the current period, capital loss
carryforward expired, and the utilization of earnings and profits distributed to
the shareholders on redemption of shares as part of the dividends paid deduction
for income tax purposes. These reclassifications have no effect on net assets or
net asset values per share. Any taxable gain remaining at fiscal year end is
distributed in the following year.

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions are
"more-likely-than-not" of being sustained by the applicable tax authority. Tax
positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006 and is to be applied
to all open tax years as of the effective date. At this time, management is
evaluating the implications of FIN 48 and its impact in the financial statements
has not yet been determined.

At September 30, 2006, the cost of securities for Federal income tax purposes,
the aggregate gross unrealized gain for all securities for which there was an
excess of value over tax cost and the aggregate gross unrealized loss for all
securities for which there was an excess of tax cost over value, were as
follows:



                                                            TAX           NET           TAX

In the event of counterparty default, the Trust has the right to collect the
collateral to offset losses incurred. There is potential loss to the Trust in
the event the Trust is delayed or prevented from exercising its rights to
dispose of the collateral securities, including the risk of a possible decline
in the value of the underlying securities during the period while the Trust
seeks to assert its rights. The Trust's investment advisor, acting under the
supervision of the Board of Trustees, reviews the value of the collateral and
the credit worthiness of those banks and dealers with which the Trust enters
into repurchase agreements to evaluate potential risks.

8. PORTFOLIO SECURITIES LOANED

The Trust lends its securities to approved brokers to earn additional income.
Within this arrangement, the Trust acts as the lender, U.S. Bancorp acts as the
agent, and other approved registered broker dealers act as the borrowers. The
Trust receives cash collateral, valued at 100% of the value of the securities on
loan, which is initially held in a segregated account at U.S. Bancorp. As agent,
U.S. Bancorp may, for investment purposes, pool the Trust's collateral in joint
accounts with cash collateral from one or more other securities lending
customers of U.S. Bancorp. Under the terms of the Trust's securities lending
agreement with U.S. Bancorp, cash collateral may be invested by U.S. Bancorp in
certain high quality, liquid investments. At September 30, 2006, the pooled cash
collateral investments consisted of repurchase agreements (46.60%), commercial
paper (34.12%), fixed income securities (15.48%), guaranteed investment contract
(3.67%) and mutual funds (0.13%). Collateral is maintained over the life of the
loan in an amount not less than the value of loaned securities, as determined at
the close of fund business each day; any additional collateral required due to
changes in security values is delivered to the Fund the next business day.
Although the collateral mitigates risk, the Trust could experience a delay in
recovering its securities and a possible loss of income or value if the borrower
fails to return the securities. The Trust has the right under the securities
lending agreement to recover the securities from the borrower on demand.

The following represents a breakdown of the collateral, its rates, and
maturities:



COLLATERAL TYPE                                               RATES                      MATURITY

9. CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM:

The Board has selected Ernst & Young LLP ("E&Y") to serve as the Funds'
independent registered public accounting firm for the fiscal year ended March
31, 2007. The decision to select E&Y was recommended by the Audit Committee and
was approved by the Board on September 25, 2006. During the Funds' fiscal years
ended March 31, 2006 and March 31, 2005, none of the Funds, their portfolios nor
anyone on their behalf consulted with E&Y on items which (i) concerned the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Funds' financial statements; or (ii) concerned the subject of a disagreement
(as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable
events (as described in paragraph (a)(1)(iv) of said Item 304).

The selection of E&Y does not reflect any disagreements with or dissatisfaction
by the Funds or the Board with the performance of the Funds' prior auditor,
PricewaterhouseCoopers LLP ("PwC"). The decision to dismiss PwC effective upon
its completion of its audits for the fiscal year ended March 31, 2006 and to
select E&Y was recommended by the Funds' Audit Committee and approved by the
Funds' Board of Trustees. PwC's report on the Funds' financial statements for
the fiscal years ended March 31, 2006 and 2005 contained no adverse opinion or

RYDEX INVESTMENTS BOARD REVIEW AND APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

The Investment Company Act of 1940 (the "1940 Act") requires that the initial
approval of, as well as the continuation of, a fund's investment advisory
agreement be specifically approved (1) by the vote of the trustees or by a vote
of the shareholders of the fund, and (2) by the vote of a majority of the
trustees who are not parties to the investment advisory agreement or "interested
persons" of any party (the "Independent Trustees"), cast in person at a meeting
called for the purpose of voting on such approval. In connection with such
approvals, the fund's trustees must request and evaluate, and the investment
adviser is required to furnish, such information as may be reasonably necessary
to evaluate the terms of the advisory agreement. In addition, the Securities and
Exchange Commission (the "SEC") takes the position that, as part of their
fiduciary duties with respect to fund fees, fund boards are required to evaluate
the material factors applicable to a decision to approve an investment advisory
agreement.

Consistent with these responsibilities, the Rydex Series Funds Board of Trustees
(the "Board") calls and holds one meeting each year that is dedicated to
considering whether to renew the investment advisory agreement between Rydex
Series Funds (the "Trust") and PADCO Advisors, Inc., which does business under
the name Rydex Investments ("Rydex Investments"), (the "Advisory Agreement")
with respect to existing funds in the Trust, including the funds discussed in
this Semi-Annual Report (each a "Fund" and collectively, the "Funds"), and to
reviewing certain other agreements pursuant to which Rydex Investments provides
investment advisory services to certain other registered investment companies.
In preparation for the meeting, the Board requests and reviews a wide variety of
materials provided by Rydex Investments, including information about Rydex
Investments' affiliates, personnel and operations. The Board also receives data
provided by third parties. This information is in addition to the detailed
information about the Funds that the Board reviews during the course of each
year, including information that relates to Fund operations and performance. The
Board also receives a memorandum from Fund counsel regarding the
responsibilities of the Board for the approval of investment advisory
agreements. In addition, the Independent Trustees receive advice from
independent counsel to the Independent Trustees, meet in executive session
outside the presence of fund management, and participate in question and answer
sessions with representatives of Rydex Investments.

At a meeting held on August 27 and 28, 2006, the Board approved the selection of
Rydex Investments and the continuance of the Advisory Agreement for an
additional one-year period, based on its review of qualitative and quantitative
information provided by Rydex Investments. The Board's approval of the Advisory
Agreement was based on consideration and evaluation of a variety of specific
factors discussed at that meeting and at prior meetings, including:

      NATURE, EXTENT AND QUALITY OF SERVICES PROVIDED BY RYDEX INVESTMENTS

      The Board reviewed the scope of services to be provided by Rydex
      Investments under the Advisory Agreement and noted that there would be no
      significant differences between the scope of services required to be
      provided by Rydex Investments for the past year and the scope of services
      required to be provided by Rydex Investments for the upcoming year. In
      reviewing the scope of services provided to the Funds by Rydex
      Investments, the Board reviewed and discussed Rydex Investments'
      investment experience, noting that Rydex Investments and its affiliates
      have committed significant resources over time to the support of the
      Funds. The Board also considered Rydex Investments' compliance program and
      its compliance record with respect to the Funds. In that regard, the Board
      noted that Rydex Investments provides information regarding the portfolio
      management and compliance to the Board on a periodic basis in connection
      with regularly scheduled meetings of the Board. In addition to the above
      considerations, the Board reviewed and considered Rydex Investments'
      investment processes and strategies, and matters related to Rydex
      Investments' portfolio transaction policies and procedures. In particular,
      the Board noted the substantial volume of portfolio trades and


50 |  THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



OTHER INFORMATION  (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      shareholder transaction activity, in general, processed by Rydex
      Investments due to the unlimited exchange policy of the majority of the
      Funds. The Board further noted that the Funds have met their investment
      objectives consistently since their relevant inception dates. Based on
      this review, the Board concluded that the nature, extent and quality of
      services to be provided by Rydex Investments to the Funds under the
      Advisory Agreement were appropriate and continued to support the Board's
      original selection of Rydex Investments as investment adviser to the
      Funds.

      FUND EXPENSES AND PERFORMANCE OF THE FUNDS AND RYDEX INVESTMENTS

      The Board reviewed statistical information prepared by Rydex Investments
      regarding the expense ratio components, including actual advisory fees,
      waivers/reimbursements, and gross and net total expenses of each Fund in
      comparison with the same information for other funds registered under the
      1940 Act determined by Rydex Investments to comprise each Fund's
      applicable peer group. Because few funds seek to provide unlimited
      exchange privileges similar to those of the Funds (other than the
      Commodities Fund, Multi-Cap Core Equity Fund, Sector Rotation Fund,
      Absolute Return Strategies Fund, Hedged Equity Fund), each Fund's
      applicable peer group is generally limited to the funds of two
      unaffiliated mutual fund families. In addition, the Board reviewed
      statistical information prepared by Rydex Investments relating to the
      performance of each Fund, as well as each Fund's ability to successfully
      track its benchmark over time, and a comparison of each Fund's performance
      to funds with similar investment objectives for the same periods and to
      appropriate indices/benchmarks, in light of total return, yield and market
      trends. The Board further noted that despite the unique nature of the
      Funds, the peer fund information presented to the Board was meaningful
      because the peer funds' investment objectives and strategies were closely
      aligned with those of the Funds. The Board noted that most of the Funds
      either outperformed their peer funds or performed in line with them over
      relevant periods. The Board also noted that the investment advisory fees
      and overall expenses for the Funds were generally lower than or in line
      with the investment advisory fee rates and overall expenses of the peer
      funds. Based on this review, the Board concluded that the investment
      advisory fees and expense levels and the historical performance of the
      Funds, as managed by Rydex Investments, as compared to the investment
      advisory fees and expense levels and performance of the peer funds, were
      satisfactory for the purposes of approving the continuance of the Advisory
      Agreement.

      COSTS OF SERVICES PROVIDED TO THE FUNDS AND PROFITS REALIZED BY RYDEX
      INVESTMENTS AND ITS AFFILIATES

      The Board reviewed information about the profitability of the Funds to
      Rydex Investments based on the advisory fees payable under the Advisory
      Agreement for the last calendar year. Rydex Investments also presented the
      Board with material discussing its methodology for determining the level
      of advisory fees assessable to the Funds. The Board analyzed the Funds'
      expenses, including the investment advisory fees paid to Rydex
      Investments. The Board also reviewed information regarding direct revenue
      received by Rydex Investments and ancillary revenue received by Rydex
      Investments and/or its affiliates in connection with the services provided
      to the Funds by Rydex Investments (as discussed below) and/or its
      affiliates. The Board also discussed Rydex Investments' profit margin as
      reflected in Rydex Investments' profitability analysis and reviewed
      information regarding economies of scale (as discussed below). Based on
      this review, the Board concluded that the profits to be realized by Rydex
      Investments and its affiliates under the Advisory Agreement and from other
      relationships between the Funds and Rydex Investments and/or its
      affiliates, if any, were within the range the Board considered reasonable
      and appropriate.

      ECONOMIES OF SCALE

      In connection with its review of the Funds' profitability analysis, the
      Board reviewed information regarding economies of scale or other
      efficiencies that may result from increases in the Funds' asset levels.
      The Board noted that the Advisory Agreement for the Funds did not provide
      for any breakpoints in the investment advisory fee rates as a result of
      increases in the asset levels of such Funds. The Board also noted that
      though Rydex Investments' assets under management were significant, the
      amount is spread among more than 95 Funds. Further limiting the
      realization of economies of scale is the ability of shareholders of a
      majority of the Funds to engage in unlimited trading. The Board also
      reviewed Rydex Investments' historic profitability as investment adviser
      to the Funds and determined that reductions in fee rates or additions of
      breakpoints were not warranted at this juncture. Based on this review, the
      Board, recognizing its responsibility to consider this issue at least
      annually, concluded that there are limited economies of scale to share
      with the Funds' shareholders.

- --------------------------------------------------------------------------------

      OTHER BENEFITS TO RYDEX INVESTMENTS AND/OR ITS AFFILIATES

      In addition to evaluating the services provided by Rydex Investments, the
      Board also considered the nature, extent, quality and cost of the
      administrative, distribution, and shareholder services performed by Rydex
      Investments' affiliates under separate agreements. The Board noted that
      Rydex Investments reports its use of soft dollars to the Board on a
      quarterly basis, as well as any portfolio transactions on behalf of the
      Funds placed through an affiliate of the Funds or Rydex Investments
      pursuant to Rule 17e-1 under the 1940 Act. Based on its review, the Board
      concluded that the nature and quality of the services provided by Rydex
      Investments' affiliates to the Trust will benefit the Funds' shareholders,
      and that any ancillary benefits would not be disadvantageous to the Funds'
      shareholders, particularly in light of the Board's view that the Funds'
      shareholders benefit from investing in a fund that is part of a large
      family of funds offering a variety of investment strategies and services.

Based on the above analysis, the Board determined that the Advisory Agreement,
including the investment advisory fee rates thereunder, are fair and reasonable
in light of all relevant circumstances and concluded that it is in the best
interest of the Funds and their shareholders to continue the Advisory Agreement.

LETTER TO OUR SHAREHOLDERS
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

Financial markets over the six-months ended September 30, 2006, were driven by a
widely anticipated "soft-landing" in the U.S. economy. This "goldilocks"
scenario had economic growth slowing, inflation and interest rates coming down
and the Federal Reserve ("Fed") ending its protracted string of increases. In
this environment, stocks rallied as corporate earnings continued to grow at
double digit rates without competition from higher interest rates. The icing on
the cake was relief from higher energy prices, which had risen relentlessly
since 2005.

While the rally in stocks was fairly broad-based, it definitely exhibited a
defensive bias. Large caps, value stocks and traditionally defensive sectors
generally outperformed small caps, growth stocks and more aggressive sectors.
This pattern is perfectly in keeping with the "late cycle" nature of the stock
market rally. Investors wanted to ride prices up, but wanted to hedge their bets
at the same time.

The large-cap nature of the rally was clearly evident in the performance of the
major averages. The home of the country's industrial giants--the Dow Jones
Industrial Average(SM)--returned 6.34%, followed by the broader S&P 500(R),
which returned 4.14%. If we look at the extremes of the capitalization spectrum,
the large-cap bias becomes more evident as the Russell Top 50(TM) Index returned
7.13% for the six month period versus a LOSS of 4.61% for the small-cap Russell
2000(R) Index.

In a defensive rally, investors are often wary of overpaying for stocks. That
was certainly true as the Russell 1000(R) Value Index returned 5.5% versus a
0.7% decline for the Russell 1000(R) Growth Index. Although developed market
international stocks did well as the MSCI EAFE Index gained 3.2%, emerging
market stocks fared poorly as the MSCI EM Index fell 1.2%.

A major catalyst for the rally in stocks was the rally in bonds. While yields on
the short end of the curve actually rose, longer dated maturities rallied with
the yield on the benchmark 10-Year Treasury note declining to 4.63% from 4.85%
during the six-month period. The catalyst for falling rates was the decline in
inflation and the Fed's pause from its extended interest rate increases. The
result was a steeply inverted yield curve. Historically, inverted yield curves
presage an economic slowdown or recession. While that remains a possibility, the
decline in long-term rates also signals the market's anticipation of an eventual
easing campaign by the Fed.

The performance of stocks at the sector level highlighted the defensive bias
towards the gains in stock prices over the past six months. The S&P 500
Utilities sector led the way with a gain of 10.2%. Although telecommunications
services, a more aggressive sector, was number two with a gain of 8.1%, consumer
staples and financials were the next best performers, gaining 7.5% and 6.5%,
respectively. It is worth noting that falling interest rates also helped both
financials and utilities. Sectors that typically perform well in a rapidly
expanding economic environment, specifically materials, industrials and
technology declined between 1.0% and 2.3% as the economy slowed.

Going into the fourth quarter, we expect that Gross Domestic Product will pick
up slightly, the Fed will remain on hold and equities will remain range-bound.
As we head into 2007, we also see the appetite for risk continuing to decline.

We appreciate the trust you have placed in our firm by investing with us.

Sincerely,


/s/ David C. Reilly

David C. Reilly, CFA
Director of Investment Strategy

ABOUT SHAREHOLDERS' FUND EXPENSES (UNAUDITED)
- --------------------------------------------------------------------------------

All mutual funds have operating expenses and it is important for our
shareholders to understand the impact of costs on their investments. As a
shareholder of the fund, you incur two types of costs: (i) transaction costs,
including sales charges (loads) on purchase payments, reinvested dividends, or
other distributions; redemption fees; and exchange fees; and (ii) ongoing costs,
including management fees, administrative services, and shareholder reports,
among others. These ongoing costs, or operating expenses, are deducted from a
fund's gross income and reduce the investment return of the fund.

A fund's expenses are expressed as a percentage of its average net assets, which
is known as the expense ratio. The following examples are intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
The examples are based on an investment of $1,000 made at the beginning of the
period and held for the entire six-month period beginning March 31, 2006 and
ending September 30, 2006.

The following tables illustrate your fund's costs in two ways:

TABLE 1. BASED ON ACTUAL FUND RETURN. This section helps you estimate the actual
    expenses that you paid over the period. The "Ending Account Value" shown is
    derived from the fund's actual return, and the fourth column shows the
    dollar amount that would have been paid by an investor who started with
    $1,000 in the fund. You may use the information here, together with the
    amount you invested, to estimate the expenses that you paid over the period.
    Simply divide your account value by $1,000 (for example, an $8,600 account
    value divided by $1,000 = 8.6), then multiply the result by the number given
    for your fund under the heading "Expenses Paid During Period."

TABLE 2. BASED ON HYPOTHETICAL 5% RETURN. This section is intended to help you
    compare your fund's cost with those of other mutual funds. The table
    provides information about hypothetical account values and hypothetical
    expenses based on the Fund's actual expense ratio and an assumed rate of
    return of 5% per year before expenses, which is not the Fund's actual
    return. The hypothetical account values and expenses may not be used to
    estimate the actual ending account balance or expenses you paid during the
    period. The example is useful in making comparisons because the U.S.
    Securities and Exchange Commission (the "SEC") requires all mutual funds to
    calculate expenses based on the 5% return. You can assess your fund's costs
    by comparing this hypothetical example with the hypothetical examples that
    appear in shareholder reports of other funds.

    Certain retirement plans such as IRA, Roth IRA and 403(b) accounts are
    charged an annual $15 maintenance fee. Upon liquidating your retirement
    account, a $15 account-closing fee will be taken from the proceeds of your
    redemption.

The calculations above assume no shares were bought or sold during the period.
Your actual costs may have been higher or lower, depending on the amount of your
investment and the timing of any purchases or redemptions.

Note that the expenses shown in the table are meant to highlight and help you
compare ongoing costs only and do not reflect any transactional costs which may
be incurred by some of the Fund's classes. These costs may include, but are not
limited to, sales charges (loads), redemption fees, and exchange fees.

You can find more information about the Fund's expenses, including annual
expense ratios for the past five years, in the Financial Highlights section of
this report. For additional information on operating expenses and other
shareholder costs, please refer to the appropriate Fund prospectus.

1. SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the SEC under the
Investment Company Act of 1940 (the "1940 Act") as a non-diversified, open-ended
investment company, and is authorized to issue an unlimited number of no par
value shares. The Trust offers five separate classes of shares, Investor Class
Shares, Advisor Class Shares, A-Class Shares, C-Class Shares, and H-Class
Shares. C-Class Shares have a 1% Contingent Deferred Sales Charge ("CDSC") if
Shares are redeemed within 12 months of purchase. Sales of shares of each Class
are made without a sales charge at the net asset value per share, with the
exception of A-Class Shares. A-Class Shares are sold at net asset value, plus
the applicable front-end sales charge. The sales charge varies depending on the
amount of your purchase, but will not exceed 4.75%. A-Class Share purchases of
$1 million or more have a 1% CDSC if Shares are redeemed within 18 months of
purchase. The current sales charge rates are as follows:

                                               SALES CHARGE       SALES CHARGE

At September 30, 2006, the Trust consisted of fifty-three separate series:
twenty-six Benchmark Funds, one Money Market Fund, nineteen Sector Funds, four
Alternative Strategy Funds, and three Essential Portfolio Funds. This report
covers the Essential Portfolio Funds (the "Funds"), while the Benchmark Funds,
the Money Market Fund, the Sector Funds, and the Alternative Strategy Funds are
contained in separate reports. Each Essential Portfolio Fund is a "fund of
funds," which means that each Fund seeks to achieve its investment objective by
investing primarily in other Rydex mutual funds (the "underlying funds") instead
of in individual securities. At September 30, 2006, only A-Class, C-Class and
H-Class Shares had been issued by the Funds. All share classes of the funds are
subject to a 1% redemption fee when shares are redeemed after being held for
less than 30 days.

The following significant accounting policies are in conformity with accounting
principles generally accepted in the United States of America and are
consistently followed by the Trust.

A. Traditional open-end investment companies ("Mutual Funds") are valued at
their Net Asset Value (the "NAV") as of the close of business, usually 4:00
p.m., Eastern Time, on the valuation date. Exchange Traded Funds ("ETFs"), and
closed-end investment companies ("closed-end funds") are valued at the last
quoted sales price.

Equity securities of the underlying Funds listed on an exchange (New York Stock
Exchange ("NYSE") or American Stock Exchange) are valued at the last quoted
sales price as of close of business on the NYSE, usually 4:00 p.m., Eastern
Time, on the valuation date. Equity securities of the underlying Funds listed on
the Nasdaq market system are valued at the Nasdaq Official Closing Price,
usually as of 4:00 p.m., Eastern Time, on the valuation date. Listed options
held by the underlying funds are valued at the Official Settlement Price listed
by the exchange, usually as of 4:00 p.m., Eastern Time. Over-the-Counter options
held by the underlying funds are valued using the average bid price obtained
from one or more security dealers. The value of futures contracts purchased and
sold by the underlying funds are accounted for using the unrealized gain or loss
on the contracts that is determined by marking the contracts to their current
realized settlement prices. Financial futures contracts held by the underlying
funds are valued at the last quoted sales price, usually as of 4:00 p.m.,
Eastern Time, on the valuation date. In the event that the exchange for a
specific futures contract closes earlier than 4:00 p.m., Eastern Time, the
futures contract is valued at the Official Settlement Price of the exchange.
However, the underlying securities from which the futures contract value is
derived are monitored until 4:00 p.m., Eastern Time, to determine if fair
valuation would provide a more accurate valuation. Short-term securities held by
the underlying funds are valued at amortized cost, which approximates market
value.

The value of domestic equity index and credit default swap agreements entered
into by the underlying funds is accounted for using the unrealized gain or loss
on the agreements that is determined by marking the agreements to the last
quoted value of the index that the swap pertains to at the close of the NYSE,
usually 4:00 p.m., Eastern Time. The swap's market value is then adjusted to
include dividends accrued, financing charges and/or interest associated with the
swap agreements.

The value of foreign equity index, commodity index, and currency index swap
agreements entered into by an underlying fund is accounted for using the
unrealized


14 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

gain or loss on the agreements that is determined by marking the agreements to
the price at which orders are being filled at the close of the NYSE, usually
4:00 p.m., Eastern Time. In the event that no order is filled at 4:00 p.m.,
Eastern Time, the security dealer provides a fair value quote at which the swap
agreement is valued. The swap's market value is then adjusted to include
dividends accrued, financing charges and/or interest associated with the swap
agreements.

Investments of the underlying funds, including structured notes, for which
market quotations are not readily available are valued at fair value as
determined in good faith by Rydex Investments (the "Advisor"), an affiliated
entity under direction of the Board of Trustees using methods established or
ratified by the Board of Trustees. These methods include, but are not limited
to: (i) general information as to how these securities and assets trade; (ii) in
connection with futures contracts and options thereupon, and other derivative
investments, information as to how (a) these contracts and other derivative
investments trade in the futures or other derivative markets, respectively, and
(b) the securities underlying these contracts and other derivative investments
trade in the cash market; and (iii) other information and considerations,
including current values in related markets.

B. Securities transactions are recorded on the trade date for financial
reporting purposes. Realized gains and losses from securities transactions are
recorded using the identified cost basis. Proceeds from lawsuits related to
investment holdings of the underlying funds are recorded as realized gains in
the respective fund. Dividend income is recorded on the ex-dividend date, net of
applicable taxes withheld by foreign countries. Interest income, including
amortization of premiums and accretion of discount, is accrued on a daily basis.

C. Distributions of net investment income and distributions of net realized
capital gains are recorded on the ex-dividend date and are determined in
accordance with income tax regulations which may differ from accounting
principles generally accepted in the United States of America. These differences
are primarily due to differing treatments for items such as deferral of wash
sales and post-October losses. Net investment income and loss, net realized
gains and losses, and net assets are not affected by these differences.

D. When a Fund, or an underlying Absolute Return Strategies Fund, and/or Hedged
Equity Fund engages in a short sale, an amount equal to the proceeds is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked-to-market to reflect the market value of the short sale.
The Fund and/or underlying funds maintain a segregated account of cash and/or
securities as collateral for short sales. The Fund and/or underlying funds are
exposed to market risk based on the amount, if any, that the market value of the
security exceeds the market value of the securities in the segregated account.
Fees, if any, paid to brokers to borrow securities in connection with short
sales are considered part of the cost of short sale transactions. In addition,
the Fund and/or underlying funds must pay out the dividend rate of the equity or
coupon rate of the treasury obligation to the purchaser and records this as an
expense. Short Dividends or Interest Expense is a cost associated with the
investment objective of short sales transactions, rather than an operational
cost associated with the day-to-day management of any mutual fund.

E. Upon the purchase of an option by an underlying fund, the premium paid is
recorded as an investment, the value of which is marked-to-market daily. When a
purchased option expires, the underlying fund will realize a loss in the amount
of the cost of the option. When the underlying fund enters into a closing sale
transaction, the underlying fund will realize a gain or loss depending on
whether the proceeds from the closing sale transaction are greater or less than
the cost of the option. When an underlying fund exercises a put option, it will
realize a gain or loss from the sale of the underlying security and the proceeds
from such sale will be decreased by the premium originally paid. When an
underlying fund exercises a call option, the cost of the security that the
underlying fund purchases upon exercise will be increased by the premium
originally paid. When an underlying fund writes (sells) an option, an amount
equal to the premium received is entered in the Trust's accounting records as an
asset and equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current value of the option written. When a
written option expires, or if the underlying fund enters into a closing purchase
transaction, the underlying fund realizes a gain (or loss if the cost of a
closing purchase transaction exceeds the premium received when the option was
sold).

F. The underlying funds may purchase or sell stock and bond index futures
contracts and options on such futures contracts. Futures contracts are contracts
for delayed delivery of securities at a specified future delivery date and at a
specific price. Upon entering into a contract, an underlying fund deposits and
maintains as collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the underlying fund
agrees to receive from or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are known as
variation margin and

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

are recorded by the underlying fund as unrealized gains or losses. When the
contract is closed, the underlying fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

G. The underlying funds may enter into swap agreements, which are
over-the-counter contracts in which one party agrees to make periodic payments
based on the change in market value of a specified equity security, basket of
equity securities, or equity index in return for periodic payments based on a
fixed or variable interest rate or the change in market value of a different
equity security, basket of equity securities, equity index, or commodity index.
Swap agreements are used to obtain exposure to an equity or market without
owning or taking physical custody of securities. In accordance with a Revenue
Ruling issued by the Internal Revenue Service (the "IRS"), the underlying
Commodity Fund will not invest in commodity index swaps after September 30,
2006.

H. The underlying funds may invest in structured notes, which are
over-the-counter contracts linked to the performance of an underlying benchmark
such as interest rates, equity markets, equity indices, commodities indices,
corporate credits or foreign exchange markets. A structured note is a type of
bond in which an issuer borrows money from investors and pays back the
principal, adjusted for performance of the underlying benchmark, at a specified
maturity date. In addition, the contract may require periodic interest payments.
Structured notes are used to obtain exposure to a market without owning or
taking physical custody of securities or commodities.

I. The underlying funds' investment securities and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollar amounts at the
date of valuation. Purchases and sales of investment securities and income and
expense items denominated in foreign currencies are translated into U.S. dollar
amounts on the respective dates of such transactions. The underlying funds do
not isolate that portion of the results of operations resulting from changes in
foreign exchange rates on investments from the fluctuations arising from changes
in market prices of securities held. Such fluctuations are included with the net
realized and unrealized gain and loss from investments.

Reported net realized foreign exchange gains or losses arise from sales of
foreign currencies and currency gains or losses realized between the trade and
settlement dates on investment transactions. Net unrealized exchange gains and
losses arise from changes in the fair values of assets and liabilities other
than investments in securities at the fiscal period end, resulting from changes
in exchange rates.

J. The underlying funds may enter into forward currency contracts primarily to
hedge against foreign currency exchange rate risks on its non-U.S. dollar
denominated investment securities. When entering into a forward currency
contract, an underlying fund agrees to receive or deliver a fixed quantity of
foreign currency for an agreed-upon price on an agreed future date. These
contracts are valued daily and the corresponding unrealized gain or loss on the
contracts is measured by the difference between the forward foreign exchange
rates at the dates of entry into the contracts and the forward rates at the
reporting date.

K. The underlying funds may also purchase American Depository Receipts, U.S.
Government securities, enter into repurchase agreements, and engage in futures,
options and swap transactions.

L. The Funds and/or underlying funds may leave cash overnight in their cash
account with the custodian, U.S. Bancorp. Periodically, a Fund or underlying
fund may have cash due to custodian bank as an overdraft balance. A fee is
incurred on this overdraft, calculated by multiplying the overdraft by a rate
based on the federal funds rate. Segregated cash with the broker is held as
collateral for investments in derivative instruments such as futures contracts
and index swap agreements.

M. Certain U.S. Government and Agency Obligations are traded on a discount
basis; the interest rates reflect the discount rates paid at the time of
purchase by the underlying funds. Other securities bear interest payable at
fixed dates through maturity.

N. The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amount of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from these
estimates.

2. FINANCIAL INSTRUMENTS

As part of their investment strategies, the underlying funds may utilize a
variety of derivative instruments, including options, futures, options on
futures, structured notes, swap agreements, and short sales. These investments
involve, to varying degrees, elements of market risk and risks in excess of the
amounts recognized in the Statements of Assets and Liabilities.


16 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

In the normal course of business, the underlying funds enter into contracts that
contain a variety of representations and warranties, which provide general
indemnifications. The underlying funds' maximum exposure under these
arrangements is unknown, as this would involve future claims that may be made
against the underlying funds and/or its affiliates that have not yet occurred.
However, based on experience, the underlying funds expect the risk of loss to be
remote.

The risk associated with purchasing options is limited to the premium originally
paid. Options written by an underlying fund involve, to varying degrees, risk of
loss in excess of the option value reflected in the Statements of Assets and
Liabilities. The risk in writing a covered call option is that an underlying
fund may forego the opportunity for profit if the market price of the underlying
security increases and the option is exercised. The risk in writing a covered
put option is that an underlying fund may incur a loss if the market price of
the underlying security decreases and the option is exercised. In addition,
there is the risk that an underlying fund may not be able to enter into a
closing transaction because of an illiquid secondary market or, for
over-the-counter options, because of the counterparty's inability to perform.
The Trust has established strict counterparty credit guidelines and enters into
transactions only with financial institutions of investment grade or better.

There are several risks in connection with the use of futures contracts. Futures
contracts involve, to varying degrees, risk of loss in excess of amounts
reflected in the financial statements. Risks may be caused by an imperfect
correlation between movements in the price of the instruments and the price of
the underlying securities. In addition, there is the risk that an underlying
fund may not be able to enter into a closing transaction because of an illiquid
secondary market.

There are several risks associated with the use of structured notes. Structured
securities are leveraged, providing an exposure to the underlying benchmark of
three times the face amount and increasing the volatility of each note relative
to the change in the underlying linked financial instrument. A highly liquid
secondary market may not exist for the structured notes an underlying fund
invests in which may make it difficult for the underlying fund to sell the
structured notes it holds at an acceptable price or to accurately value them. In
addition, structured notes are subject to the risk that the counterparty to the
instrument, or issuer, might not pay interest when due or repay principal at
maturity of the obligation. Although the Trust will not invest in any structured
notes unless the Advisor believes that the issuer is creditworthy, an underlying
fund does bear the risk of loss of the amount expected to be received in the
event of the default or bankruptcy of the issuer. The Trust has established
strict counterparty credit guidelines and enters into transactions only with
financial institutions of investment grade or better.

The use of swaps involves risks that are different from those associated with
ordinary portfolio securities transactions. Swap agreements may be considered to
be illiquid. Although the Trust will not enter into any swap agreement unless
the Advisor believes that the other party to the transaction is creditworthy,
the underlying funds bear the risk of loss of the amount expected to be received
under a swap agreement in the event of the default or bankruptcy of the
agreement counterparty. The Trust has established strict counterparty credit
guidelines and enters into transactions only with financial institutions of
investment grade or better.

Short sales are transactions in which a Fund or an underlying Absolute Return
Strategies Fund, and/or Hedged Equity Fund sells a security it does not own. If
the security the Fund and/or underlying funds sold short goes down in price
between the time the Fund and/or underlying funds sell the security and closes
its short position, the Fund and/or underlying funds will realize a gain on the
transaction. Conversely, if the security goes up in price during the period, the
Fund and/or underlying funds will realize a loss on the transaction. The risk of
such price increases is the principal risk of engaging in short sales.

In conjunction with the use of options, futures, options on futures, swap
agreements, as well as short sales of securities, the underlying funds are
required to maintain collateral in various forms. The underlying funds use,
where appropriate, depending on the financial instrument utilized and the broker
involved, margin deposits at the broker, cash and/or securities segregated at
the custodian bank, discount notes, or the repurchase agreements allocated to
each underlying fund.

The risks inherent in the use of options, futures contracts, options on futures
contracts, structured notes, swap agreements, as well as short sales of
securities include i) adverse changes in the value of such instruments; ii)
imperfect correlation between the price of the instruments and movements in the
price of the underlying securities, indices, or futures contracts; iii) the
possible absence of a liquid secondary market for any particular instrument at
any time; and iv) the potential of counterparty default.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

As part of its agreement with the Trust, the Advisor will pay all expenses of
the Essential Portfolios, including the cost of transfer agency, fund
administration, audit and other services, excluding interest expense, taxes
(expected to be de minimis), brokerage commissions and other expenses connected
with the execution of portfolio transactions, short dividend expenses, and
extraordinary expenses.

Each Fund will also indirectly bear a proportionate share of the total operating
expenses (including investment management, shareholder servicing, custody,
transfer agency, audit and other underlying fund expenses) of the underlying
funds in which the Funds invest. In addition, some underlying funds charge
redemption fees if a shareholder, including a Fund, redeems shares before the
end of the funds' requisite holding period. Therefore, if a Fund sells shares of
an underlying fund that are subject to a redemption fee, the Fund will be
responsible for paying the redemption fee to the underlying fund.

Rydex Investments, an affiliated entity, provides transfer agent and
administrative services to the Funds. However, the related fees are paid by the
Advisor, as noted above.

Rydex Investments also provides accounting services to the Funds. However, the
related fees are paid by the Advisor, as noted above. Certain officers and
trustees of the Trust are also officers of Rydex Investments.

The Funds have not adopted a Distribution Plan and a Shareholder Services Plan
with respect to A-Class Shares and H-Class Shares. Instead, the Funds invest in
underlying funds that have a distribution plan that allows the underlying funds
to pay distribution fees to the Distributor and other firms that provide
distribution services ("Service Providers"). The underlying funds will pay
distribution fees to the Distributor at an annual rate not to exceed 0.25% of
average daily net assets, pursuant to Rule 12b-1 under the 1940 Act, as amended.
If a Service Provider provides distribution or shareholder services, the
Distributor will, in turn, pay the Service Provider for the services it provides
at an annual rate not to exceed 0.25% of the average daily net assets of a Fund.

The Funds have adopted a Distribution Plan and a Shareholder Services Plan
pursuant to Rule 12b-1 under the 1940 Act, as amended, applicable to C-Class
Shares that allows the Funds to pay annual distribution and service fees of
0.75% of the Funds' average daily net assets. The annual 0.50% distribution fee
reimburses the Distributor for paying the shareholders' financial advisors an
on-going sales commission. The annual 0.25% service fee compensates the
shareholders' financials advisors for providing ongoing services to the
shareholders. The Distributor advances the first year's distribution and service
fees, and retains the distribution and service fees on accounts with no
authorized intermediary of record.

4. FEDERAL INCOME TAX INFORMATION

The Funds intend to comply with the provisions of the Internal Revenue Code
applicable to regulated investment companies and will distribute all net
investment income and capital gains to shareholders. Therefore, no Federal
income tax provision is required.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. These differences are primarily due to
differing treatments for losses deferred due to wash sales, losses deferred due
to post-October losses, and excise tax regulations.

Permanent book and tax basis differences, if any, relating to shareholder
distributions will result in reclassifications to paid-in capital. This includes
net operating losses not utilized during the current year, capital loss
carryforward expired, and the utilization of earnings and profits distributed to
the shareholders on redemption of shares as part of the dividends paid deduction
for income tax purposes. These reclassifications have no effect on net assets or
net asset values per share. Any taxable gain remaining at fiscal year end is
distributed in the following year.

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the fund's tax returns to determine whether the tax positions are
"more-likely-than-not" of being sustained by the applicable tax authority. Tax
positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006 and is to be applied
to all open tax years as of the effective date. At this time, management is
evaluating the implications of FIN 48 and its impact in the financial statements
has not yet been determined.

7. CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board has selected Ernst & Young LLP (E&Y) to serve as the Funds'
independent registered public accounting firm for the fiscal year ended March
31, 2007. The decision to select E&Y was recommended by the Audit Committee and
was approved by the Board on September 25, 2006. During the Funds' fiscal years
ended March 31, 2006 and March 31, 2005, none of the Funds, their portfolios nor
anyone on their behalf consulted with E&Y on items which (i) concerned the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Funds' financial statements; or (ii) concerned the subject of a disagreement
(as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable
events (as described in paragraph (a)(1)(iv) of said Item 304).

The selection of E&Y does not reflect any disagreements with or dissatisfaction
by the Funds or the Board with the performance of the Funds' prior auditor,
PricewaterhouseCoopers LLP (PwC). The decision to dismiss PwC effective upon its
completion of its audits for the fiscal year ended March 31, 2006 and to select
E&Y was recommended by the Funds' Audit Committee and approved by the Funds'
Board of Trustees. PwC's report on the Funds' financial statements for the
fiscal years ended March 31, 2006 and 2005 contained no adverse opinion or
disclaimer of opinion nor were they qualified or modified as to uncertainty,
audit scope or accounting principles. During the Funds' fiscal years ended March
31, 2006 and March 31, 2005, (i) there were no disagreements with PwC on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedure, which disagreements, if not resolved to the
satisfaction of PwC, would have caused it to make reference to the subject
matter of the disagreements in connection with its report on the Funds'
financial statements for such years, and (ii) there were no "reportable events"
of the kind described in Item 304(a)(1)(v) of Regulation SK under the Securities
and Exchange Act of 1934, as amended.

RYDEX INVESTMENTS BOARD REVIEW AND APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

The Investment Company Act of 1940 (the "1940 Act") requires that the initial
approval of, as well as the continuation of, a fund's investment advisory
agreement be specifically approved (1) by the vote of the trustees or by a vote
of the shareholders of the fund, and (2) by the vote of a majority of the
trustees who are not parties to the investment advisory agreement or "interested
persons" of any party (the "Independent Trustees"), cast in person at a meeting
called for the purpose of voting on such approval. In connection with such
approvals, the fund's trustees must request and evaluate, and the investment
adviser is required to furnish, such information as may be reasonably necessary
to evaluate the terms of the advisory agreement. In addition, the Securities and
Exchange Commission (the "SEC") takes the position that, as part of their
fiduciary duties with respect to fund fees, fund boards are required to evaluate
the material factors applicable to a decision to approve an investment advisory
agreement.

Consistent with these responsibilities, the Rydex Series Funds Board of Trustees
(the "Board") calls and holds one meeting each year that is dedicated to
considering whether to renew the investment advisory agreement between Rydex
Series Funds (the "Trust") and PADCO Advisors, Inc., which does business under
the name Rydex Investments ("Rydex Investments"), (the "Advisory Agreement")
with respect to existing funds in the Trust, including the funds discussed in
this Semi-Annual Report (each a "Fund" and collectively, the "Funds"), and to
reviewing certain other agreements pursuant to which Rydex Investments provides
investment advisory services to certain other registered investment companies.
In preparation for the meeting, the Board requests and reviews a wide variety of
materials provided by Rydex Investments, including information about Rydex
Investments' affiliates, personnel and operations. The Board also receives data
provided by third parties. This information is in addition to the detailed
information about the Funds that the Board reviews during the course of each
year, including information that relates to Fund operations and performance. The
Board also receives a memorandum from Fund counsel regarding the
responsibilities of the Board for the approval of investment advisory
agreements. In addition, the Independent Trustees receive advice from
independent counsel to the Independent Trustees, meet in executive session
outside the presence of fund management, and participate in question and answer
sessions with representatives of Rydex Investments.

At a meeting held on August 27 and 28, 2006, the Board approved the selection of
Rydex Investments and the continuance of the Advisory Agreement for an
additional one-year period, based on its review of qualitative and quantitative
information provided by Rydex Investments. The Board's approval of the Advisory
Agreement was based on consideration and evaluation of a variety of specific
factors discussed at that meeting and at prior meetings, including:

      NATURE, EXTENT AND QUALITY OF SERVICES PROVIDED BY RYDEX INVESTMENTS

      The Board reviewed the scope of services to be provided by Rydex
      Investments under the Advisory Agreement and noted that there would be no
      significant differences between the scope of services required to be
      provided by Rydex Investments for the past year and the scope of services
      required to be provided by Rydex Investments for the upcoming year. In
      reviewing the scope of services provided to the Funds by Rydex
      Investments, the Board reviewed and discussed Rydex Investments'
      investment experience, noting that Rydex Investments and its affiliates
      have committed significant resources over time to the support of the
      Funds. The Board also considered Rydex Investments' compliance program and
      its compliance record with respect to the Funds. In that regard, the Board
      noted that Rydex Investments provides information regarding the portfolio
      management and compliance to the Board on a periodic basis in connection
      with regularly scheduled meetings of the Board. In addition to the above
      considerations, the Board reviewed and considered Rydex Investments'
      investment processes and strategies, and matters related to


22 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


OTHER INFORMATION (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

      Rydex Investments' portfolio transaction policies and procedures. In
      particular, the Board noted the substantial volume of portfolio trades and
      shareholder transaction activity, in general, processed by Rydex
      Investments due to the unlimited exchange policy of the majority of the
      Funds. The Board further noted that the Funds have met their investment
      objectives consistently since their relevant inception dates. Based on
      this review, the Board concluded that the nature, extent and quality of
      services to be provided by Rydex Investments to the Funds under the
      Advisory Agreement were appropriate and continued to support the Board's
      original selection of Rydex Investments as investment adviser to the
      Funds.

      FUND EXPENSES AND PERFORMANCE OF THE FUNDS AND RYDEX INVESTMENTS

      The Board reviewed statistical information prepared by Rydex Investments
      regarding the expense ratio components, including actual advisory fees,
      waivers/reimbursements, and gross and net total expenses of each Fund in
      comparison with the same information for other funds registered under the
      1940 Act determined by Rydex Investments to comprise each Fund's
      applicable peer group. Because few funds seek to provide unlimited
      exchange privileges similar to those of the Funds (other than the
      Commodities Fund, Multi-Cap Core Equity Fund, Sector Rotation Fund,
      Absolute Return Strategies Fund, and Hedged Equity Fund), each Fund's
      applicable peer group is generally limited to the funds of two
      unaffiliated mutual fund families. In addition, the Board reviewed
      statistical information prepared by Rydex Investments relating to the
      performance of each Fund, as well as each Fund's ability to successfully
      track its benchmark over time, and a comparison of each Fund's performance
      to funds with similar investment objectives for the same periods and to
      appropriate indices/benchmarks, in light of total return, yield and market
      trends. The Board further noted that despite the unique nature of the
      Funds, the peer fund information presented to the Board was meaningful
      because the peer funds' investment objectives and strategies were closely
      aligned with those of the Funds. The Board noted that most of the Funds
      either outperformed their peer funds or performed in line with them over
      relevant periods. The Board also noted that the investment advisory fees
      and overall expenses for the Funds were generally lower than or in line
      with the investment advisory fee rates and overall expenses of the peer
      funds. Based on this review, the Board concluded that the investment
      advisory fees and expense levels and the historical performance of the
      Funds, as managed by Rydex Investments, as compared to the investment
      advisory fees and expense levels and performance of the peer funds, were
      satisfactory for the purposes of approving the continuance of the Advisory
      Agreement.

      COSTS OF SERVICES PROVIDED TO THE FUNDS AND PROFITS REALIZED BY RYDEX
      INVESTMENTS AND ITS AFFILIATES

      The Board reviewed information about the profitability of the Funds to
      Rydex Investments based on the advisory fees payable under the Advisory
      Agreement for the last calendar year. Rydex Investments also presented the
      Board with material discussing its methodology for determining the level
      of advisory fees assessable to the Funds. The Board analyzed the Funds'
      expenses, including the investment advisory fees paid to Rydex
      Investments. The Board also reviewed information regarding direct revenue
      received by Rydex Investments and ancillary revenue received by Rydex
      Investments and/or its affiliates in connection with the services provided
      to the Funds by Rydex Investments (as discussed below) and/or its
      affiliates. The Board also discussed Rydex Investments' profit margin as
      reflected in Rydex Investments' profitability analysis and reviewed
      information regarding economies of scale (as discussed below). Based on
      this review, the Board concluded that the profits to be realized by Rydex
      Investments and its affiliates under the Advisory Agreement and from other
      relationships between the Funds and Rydex Investments and/or its
      affiliates, if any, were within the range the Board considered reasonable
      and appropriate.

      ECONOMIES OF SCALE

      In connection with its review of the Funds' profitability analysis, the
      Board reviewed information regarding economies of scale or other
      efficiencies that may result from increases in the Funds' asset levels.
      The Board noted that the Advisory Agreement for the Funds did not provide
      for any breakpoints in the investment advisory fee rates as a result of
      increases in the asset levels of such Funds. The Board also noted that
      though Rydex Investments' assets under management were significant, the
      amount is spread among more than 95 Funds. Further limiting the
      realization of economies of scale is the ability of shareholders of a
      majority of the Funds to engage in unlimited trading. The Board also
      reviewed Rydex Investments' historic profitability as investment adviser
      to the Funds and determined that reductions in fee rates or additions of
      breakpoints were not warranted at this juncture. Based on this review, the
      Board, recognizing its responsibility to consider this issue at least
      annually, concluded that there are limited economies of scale to share
      with the Funds' shareholders.

OTHER INFORMATION (UNAUDITED) (CONCLUDED)
- --------------------------------------------------------------------------------

      OTHER BENEFITS TO RYDEX INVESTMENTS AND/OR ITS AFFILIATES

      In addition to evaluating the services provided by Rydex Investments, the
      Board also considered the nature, extent, quality and cost of the
      administrative, distribution, and shareholder services performed by Rydex
      Investments' affiliates under separate agreements. The Board noted that
      Rydex Investments reports its use of soft dollars to the Board on a
      quarterly basis, as well as any portfolio transactions on behalf of the
      Funds placed through an affiliate of the Funds or Rydex Investments
      pursuant to Rule 17e-1 under the 1940 Act. Based on its review, the Board
      concluded that the nature and quality of the services provided by Rydex
      Investments' affiliates to the Trust will benefit the Funds' shareholders,
      and that any ancillary benefits would not be disadvantageous to the Funds'
      shareholders, particularly in light of the Board's view that the Funds'
      shareholders benefit from investing in a fund that is part of a large
      family of funds offering a variety of investment strategies and services.

Based on the above analysis, the Board determined that the Advisory Agreement,
including the investment advisory fee rates thereunder, are fair and reasonable
in light of all relevant circumstances and concluded that it is in the best
interest of the Funds and their shareholders to continue the Advisory Agreement.

Item 11. Controls and Procedures.

(a) Based on their evaluation on December 7, 2006, the President (principal
executive officer) and the Treasurer (principal financial officer) of the Rydex
Series Funds (the "Trust") believe that there were no significant deficiencies
in the design or operation of the internal controls of the Trust or Rydex
Investments ("RI"), the investment advisor and manager of the Trust, or Rydex
Distributors, Inc. ("RD"), which acts as distributor for the Trust, including
disclosure controls and procedures (as defined in Rule 30a-3(c) under the
Investment Company Act of 1940) which would have adversely affected the ability
of the Trust or RGA on behalf of the Trust, to record, process, summarize, and
report the subject matter contained in this Report, and the President and
Treasurer of the Trust have identified no material weaknesses in such internal
controls on behalf of the Trust.

There was no fraud, whether or not material, involving officers or employees of
RI, RD or the Trust who have a significant role in the Trust's internal
controls, including disclosure controls and procedures (as defined in Rule
30a-3(c) under the Investment Company Act of 1940) that has come to the
attention of the Advisor or the officers of the Trust, including its President
and Treasurer.

(b) There were no significant changes in the Trust's or RI's internal controls
over financial reporting, (as defined in Rule 30a-3(d) under the Investment
Company Act of 1940) that occurred during the second fiscal quarter of the
period covered by this report that has materially affected, or is reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
