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

DEAR SHAREHOLDER:

The U.S. economy reached a more mature phase of the business cycle during the
six-month period ending September 30, 2004. This phenomenon was marked by lower
realized and forecasted gross domestic product (GDP) growth rates, reduced
forecasts for future corporate earnings growth and a cumulative reported one
million jobs created during the period. The Federal Reserve (Fed), observing
these changes, raised the Fed Funds rate three times between June 30 and
September 21. Inflation, as measured both by the Consumer Price Index (+1.7%)
and Producer Price Index (+1.9%), rose during this time period.

Equity markets moved in a tight trading range over the period. Most broad-based
equity indices ended the period with slightly negative returns. The S&P 500(R)
Index was down slightly, returning -0.18% over the period. Large-cap stocks
tended to outperform small-cap stocks and the S&P 500 outperformed the S&P
MidCap 400 TM and Russell 2000(R) indices, which returned -1.15% and -2.40%,
respectively. Political and economic uncertainty led investors to return to the
relative safety of large-cap stocks. The S&P 500 also outperformed the Nasdaq
100 Index(R), which posted a return of -1.79%.

There was good news, though. Between the end of March and September, the
unemployment rate experienced a slight decline, moving from 5.6% to 5.4%.The
improvement was driven in part by a 2.8% rebound in manufacturing payrolls.

RYDEX VALUE AND GROWTH FUNDS

During a period that demonstrated no clear direction for the economy, investors
gravitated toward the generally perceived less risky value stocks, which
outperformed growth stocks. For large-cap stocks, the S&P 500/Barra Value Index
rose 0.81%, 3.70% more than the S&P 500/Barra Growth Index, which slid
- -2.89%.The S&P MidCap 400/Barra Value Index fell 0.39% during the period,
outpacing the -2.64% return of the S&P MidCap 400/Barra Growth Index. Likewise,
the S&P SmallCap 600/Barra Value Index outperformed the S&P SmallCap 600/Barra
Growth Index by 1.54%, with both indices returning 2.51% and 0.97%,
respectively. In line with the market trend of value outperforming growth, Rydex
Small-Cap Value Fund H-Class returned a positive 2.54%, while Rydex Large-Cap
Growth Fund H-Class returned -3.60%.

RYDEX INTERNATIONAL FUNDS

International stocks were mixed as European stocks rose and Japanese stocks fell
during the past six months. Stronger growth prospects and controlled inflation
helped to increase stock prices in Europe. Japanese stocks sold off in May when
the market became concerned about a possible slow down in China's economy. The
Dow Jones Stoxx SM 50 Index rose 0.20% in U.S. dollar terms while the Topix 100
Index fell 7.82% in U.S. dollar terms. Returns in Europe benefited from a 1%
appreciation of the euro while Japanese returns were hurt by a 5% depreciation
of the yen. Rydex Large-Cap Europe Fund H-Class was up 2.74% and Rydex Large-Cap
Japan Fund H-Class closed the period down -17.14%.

RYDEX BOND FUNDS

The price of the Long Bond fell during April and May, raising the yield to a
high of 5.56%, as an increase in inflation led investors to anticipate higher
yields long term. In mid-June, core CPI came in below forecasts for the first
time this year and Fed Chairman Alan Greenspan strongly reiterated the Fed's
stance to raise rates at a "measured pace," removing inflationary pressures from
the market. This outlook, along with increasing oil prices, prompted the Long
Bond to rally and the yield to tumble to a low of 4.77% on September 27, 2004,
and move up slightly to 4.90% to close out the period. With the rise in price of
the Long Bond and the corresponding drop in yield, Rydex Juno Fund Investor
Class, which seeks to provide total returns that will inversely correlate to the
current LongTreasury Bond, turned from positive to negative and closed out the
period with a total return of -1.21%. As the price of the bond moved higher,
Rydex U.S. Government Bond Fund Investor Class did an about-face from its
negative position, returning a positive 0.45%.

As always, we appreciate the trust you have placed in our firm's quality and
integrity by investing with us.

Sincerely,


/s/ Carl G. Verboncoeur

ABOUT SHAREHOLDERS FUND'S EXPENSES
- --------------------------------------------------------------------------------

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 may incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments, reinvested
dividends, or other distributions; redemption fees; and exchange fees; and (2)
ongoing costs, including management fees, administrative services, and
shareholder reports, among others. Operating expenses, which are deducted from a
fund's gross income, 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, 2004
and ending September 30, 2004.

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."

   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.

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. In addition, 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
   example is useful in making comparisons because the Securities Exchange
   Commission 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.

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.

See Notes to Financial Statements.

104 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



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

1.   SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the Securities and
Exchange Commission 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 six separate classes
of shares, Investor Class Shares, Advisor Class Shares, A-Class Shares, C-Class
Shares, H-Class Shares and Institutional Class Shares. 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. C-Class Shares have a 1% Contingent Deferred Sales
Charge ("CDSC") if Shares are redeemed within 12 months of purchase. 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% Contingent
Deferred Sales Charge ("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
AMOUNT OF INVESTMENT                      OFFERING PRICE    AMOUNT INVESTED

At September 30, 2004, the Trust consisted of forty-three separate series:
twenty-two Benchmark Funds, one Money Market Fund, eighteen Sector Funds and two
Strategic Funds. This report covers the twenty-two Benchmark Funds and the Money
Market Fund (the "Funds"), while the Sector Funds and the Strategic 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. 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 their last bid
price. 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.

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 agreement.

The value of foreign 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 average price at which orders are
being filled (the "average fill price") 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
agreement.

Short-term securities, if any, are valued at amortized cost, which approximates
market value. Securities and assets, including index options, for which market
quotations are not readily available, are valued at fair value as determined in
good faith by or under direction of the Board of Trustees or by the Advisor
using methods established or ratified by the Board of Trustees. The shares of
the Master Portfolios held by the Feeder Funds are valued at their respective
daily Net Asset Value.

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. 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. Net investment income is computed and dividends are declared daily in the
U.S. Government Bond Fund and the U.S. Government Money Market Fund. Income
dividends in these funds are paid monthly. 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.
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. 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.

D. 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 securities as collateral for short
sales. The Fund is exposed to market risk based on the amount, if any, that

                                 THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT | 105



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

the market value of the stock exceeds the market value of the securities in the
segregated account.

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 a 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, the 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 a 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 equity index 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.

H. 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.

I. 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, the 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.

J. Segregated Cash with 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 fund. Other securities bear
interest at the rates shown, payable at fixed dates through maturity.

L. 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 based upon the
respective aggregate net assets value of each Fund included in the Trust.

M. 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, 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.

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 equity swaps involves risks that are different from those associated
with ordinary portfolio securities transactions. Swap agreements may be
considered to be illiquid. Although a fund 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.

In conjunction with the use of options, futures, options on futures and 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 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, and swap agreements include 1) adverse changes in the value of such
instruments; 2) imperfect correlation between the price of the instruments and
movements in the price of the underlying securities, indices, or futures
contracts; 3) the possible absence of a liquid secondary market for any
particular instrument at any time; and 4) the potential of counterparty default.

3. MASTER-FEEDER ARRANGEMENT

Currently, the Nova Fund, the Ursa Fund, the Juno Fund, and the Arktos 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-end 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 its 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, Ursa
Master Portfolio, Arktos Master Portfolio, and Juno Master Portfolio owned by
the Nova Fund, the Ursa Fund, the Arktos Fund, and the Juno Fund, respectively,
at September 30, 2004, 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 Rydex Global
Advisors (the "Advisor"), an affiliated entity, investment advisory fees
calculated at an annualized rate of 0.50% of the average daily net assets of the
U.S. Government Bond Fund and the U.S. Government Money Market Fund; 0.75% of
the average daily net assets of the OTC 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 Medius Fund, the Mekros Fund,
the Large-Cap Europe Fund, the Large-Cap Japan Fund, the Inverse Small-Cap Fund,
the Inverse Mid-Cap Fund, the Ursa Master Portfolio, the Arktos Master
Portfolio, and the Juno Master Portfolio. For the period ending September 30,
2004, the Advisor voluntarily reimbursed $25,896 of miscellaneous expenses in
the Institutional Class of the U.S. Government Money Market Fund. These fees are
permanently reimbursed and are not subject to recapture by the Advisor. Certain
officers and trustees of the Trust are also officers of Rydex Global Advisors.

Rydex Fund Services, Inc. (the "Servicer"), 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 U.S.
Government Bond Fund and the U.S. Government Money Market Fund; and 0.25% of the
average daily net assets of the Nova Fund, the Ursa Fund, the OTC Fund, the
Arktos Fund, the Medius Fund, the Inverse Mid-Cap Fund, the Mekros Fund, the
Inverse Small-Cap Fund, the Juno Fund, the Large-Cap Europe Fund, the Large-Cap
Japan 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. For the
period ended September 30, 2004, the Sevicer voluntarily waived transfer agent
service fees in the amount of $50,000 in the Institutional Class of the U.S.
Government Money Market Fund. These fees are permanently waived and not subject
to recapture by the Servicer.

The Servicer 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. For the period
ended September 30, 2004, the Servicer voluntarily waived accounting fees in the
amount of $12,702 in the Institutional Class of the U.S. Government Money Market
Fund. These fees are permanently waived and not subject to recapture by the
Servicer . Certain officers and trustees of the Trust are also officers of Rydex
Fund Services, Inc.

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. For the
period ended September 30, 2004, the Distributor voluntarily waived $283,204 of
12b-1 expenses in the Advisor Class and $23 of 12b-1 expenses in the A-Class of
the U.S. Government Money Market Fund. These fees are permanently waived and are
not subject to recapture by the Distributor.

The Trust has adopted a separate Distribution and Shareholder Services Plan (the
"C-Class 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 on-going sales commission. The
Distributor advances the first year's service and distribution fees. The
Distributor retains the service and distribution fees on accounts with no
authorized dealer of record. For the period ended September 30, 2004, the
Distributor waived $569,947 of C-Class Plan expenses in the C-Class of the U.S.
Government Money Market Fund. These fees are permanently waived and not subject
to recapture by the Distributor. Certain officers and trustees of the Trust are
also officers of Rydex Distributors, Inc.

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
the utilization of earnings and profits distributed to shareholders on
redemption of shares as part of the dividends paid deduction for income tax
purposes, net operating losses not utilized during the current year, and
differences in the treatment of certain notional principal contracts. 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.

The Funds transfer uninvested cash balances into a single joint account, along
with the uninvested cash balance of the Core Equity Fund (included in the Trust,
but contained in a separate report). 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 Trusts' custodian and is
evaluated daily to ensure that its market value exceeds the delivery value of
the repurchase agreement at maturity.

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.

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

9. 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. Bank acts as the
agent, and other approved registered broker dealers act as the borrowers. The
Trust receives cash collateral, valued at 102% of the value of the securities on
loan, which is initially held in a segregated account at U.S. Bank. As agent,
U.S. Bank 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. Bank. Under the terms of the Trust's securities lending
agreement with U.S. Bank, cash collateral may be invested by U.S. Bank in
certain high quality, liquid investments. At September 30, 2004, the pooled cash
collateral investments consisted of repurchase agreements (41.98%), commercial
paper (27.65%), fixed income notes (24.41%), corporate bonds (5.95%) and mutual
funds (0.01%). 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.

At September 30, 2004 the following funds participated in securities lending and
received cash collateral:

                                                             VALUE OF

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

DEAR SHAREHOLDER:

The U.S. economy reached a more mature phase of the business cycle during the
six-month period ending September 30, 2004. This phenomenon was marked by lower
realized and forecasted gross domestic product (GDP) growth rates, reduced
forecasts for future corporate earnings growth and a cumulative reported one
million jobs created during the period. The Federal Reserve (Fed), observing
these changes, raised the Fed Funds rate three times between June 30 and
September 21.

Equity investors reacted to slowing growth by shifting their style preference
from high-growth to value stocks. As a result of investors' shift toward value
stocks, the information technology sector suffered significant price declines in
all industries but most acutely in semiconductors. Correspondingly, Rydex
Electronics Fund Investor Class and Rydex Technology Fund Investor Class
returned -27.40% and -13.33%, respectively, during the semi-annual period.

Equity markets moved in a tight trading range over the period. Most broad-based
equity indices ended the period with slightly negative returns. The S&P 500(R)
Index was down slightly, returning -0.18% over the period. Large-cap stocks
tended to outperform small-cap stocks and the S&P 500 outperformed the S&P
MidCap 400(TM) and Russell 2000(R) indices, which returned -1.15% and -2.40%,
respectively. Political and economic uncertainty led investors to return to the
relative safety of large-cap stocks. The S&P 500 also outperformed the Nasdaq
100 Index(R), which posted a return of -1.79%.

There was good news, though. Between the end of March and September, the
unemployment rate experienced a slight decline, moving from 5.6% to 5.4%. The
improvement was driven in part by a 2.8% rebound in manufacturing payrolls.

Oil prices increased almost 40% in the last six months. Despite the threat this
development poses to continued stable economic growth, market reactions were
muted. Implied volatility in financial markets, as measured by the VIX--which
measures the volatility of the U.S. equity market--reached the lowest levels
seen since 1995.

While the longer-term broad market reaction to oil prices was reserved,
individual sectors responded dramatically. Year-over-year energy sector earnings
grew 60% during the quarterly period ending June 2004. Investors responded by
marking up energy stocks significantly. The sector, which returned 19.4% for the
period, greatly outperformed the S&P 500. Rydex Energy Services Fund Investor
Class and Rydex Energy Fund Investor Class benefited significantly as well,
returning 18.63% and 18.34%, respectively.

Industrials also performed well, up 8.4%. Other sectors that performed well
included basic materials, which was up 6.2%, telecommunication services (5.4%)
and utilities (5.1%). Information technology and consumer staples experienced
some difficult times, finishing down 7.3% and down 5.1%, respectively. Health
care (-2.8%), financials (-2%) and consumer discretionary (-1.5%) also
underperformed the S&P 500.

Though five sectors had positive returns and five sectors had negative returns,
investors should not assume that sector investing was flat. Not only was the
spread between the best and worst sector fairly large (26.7%), but the sectors
that outperformed only represent 27% of the S&P 500's market capitalization.

As always, we appreciate the trust you have placed in our firm's quality and
integrity by investing with us.

Sincerely,


/s/ Carl G. Verboncoeur

2 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


ABOUT SHAREHOLDERS FUND'S EXPENSES
- --------------------------------------------------------------------------------

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 may incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments, reinvested
dividends, or other distributions; redemption fees; and exchange fees; and (2)
ongoing costs, including management fees, administrative services, and
shareholder reports, among others. Operating expenses, which are deducted from a
fund's gross income, 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, 2004 and
ending September 30, 2004.

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."

      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.

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. In addition, 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 example is useful in
      making comparisons because the Securities Exchange Commission 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.

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.

68 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


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

1. SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the Securities and
Exchange Commission under the Investment Company Act of 1940 (the "1940 Act") as
a nondiversified, open-ended investment company, and is authorized to issue an
unlimited number of no par value shares. The Trust offers six separate classes
of shares, Investor Class Shares, Advisor Class Shares, A-Class Shares, C-Class
Shares, H-Class Shares and Institutional Class Shares. 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. C-Class Shares have a 1% Contingent Deferred Sales
Charge ("CDSC") if Shares are redeemed within 12 months of purchase. 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% Contingent
Deferred Sales Charge ("CDSC") if Shares are redeemed within 18 months of
purchase. The current sales charge rates are as follows:

                               SALES CHARGE AS % OF     SALES CHARGE AS % OF NET
AMOUNT OF INVESTMENT              OFFERING PRICE             AMOUNT INVESTED
- --------------------------------------------------------------------------------

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%
Greater than $1,000,000                0.00%                      0.00%

At September 30, 2004, the Trust consisted of forty-three separate series:
twenty-two Benchmark Funds, one Money Market Fund, eighteen Sector Funds, and
two Strategic Funds. This report covers the eighteen Sector Funds (the "Funds"),
while the Money Market Fund, the Benchmark Funds and the Strategic Funds are
contained in separate reports. At September 30, 2004, none of the Funds have
issued Institutional Class Shares.

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 their last bid
price. 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 is 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.

Short-term securities, if any, are valued at amortized cost, which approximates
market value. Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under
direction of the Board of Trustees or by the Advisor using methods established
or ratified by the Board of Trustees.

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. 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 the 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.

D. Distributions to shareholders 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, post-October losses and regulated futures contracts and options.

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

E. Each Fund seeks capital appreciation and invests substantially all of its
assets in equity securities of companies involved in its sector. The Funds may
also purchase American Depository Receipts ("ADRs") and U.S. Government
securities, enter into repurchase agreements, and engage in futures, options and
equity swap transactions. The risks inherent in the use of futures, options and
swaps agreements include 1) adverse changes in the value of such instruments; 2)
imperfect correlation between the price of the instruments and movements in the
price of the underlying securities; 3) the possible absence of a liquid
secondary market for any particular instrument at any time; and 4) the potential
of counterparty default.

F. 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. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of an investment advisory contract, the Trust pays Rydex Global
Advisors, (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. Certain officers and trustees of the Trust are also
officers of Rydex Global Advisors.

Rydex Fund Services, Inc. (the "Servicer"), 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
Funds.

The Servicer 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 Fund Services.

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
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 on-going sales commission. The Distributor advances the
first year's service and distribution fees. 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 Rydex Distributors, Inc.

3. 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.


70 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


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

Permanent book and tax basis differences, if any, relating to shareholder
distributions will result in reclassifications to paid-in capital. This
includes the utilization of earnings and profits distributed to shareholders on
redemption of shares as part of the dividends paid deduction for income tax
purposes, net operating losses not utilized during the current year, and
differences in the treatment of certain notional principal contracts. 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.

TAX BASIS UNREALIZED GAIN (LOSS) ON INVESTMENTS AND DISTRIBUTIONS

At September 30, 2004, 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

4. REPURCHASE AGREEMENTS

The Funds transfer uninvested cash balances into a single joint account, along
with uninvested cash balances of the Sector Rotation Fund (included in the
Trust, but contained in a separate report) and the Rydex Dynamic Funds (the
Titan Master Portfolio, the Tempest Master Portfolio, the Venture Master
Portfolio, the Dynamic Dow Master Portfolio, and the Inverse Dynamic Dow Master
Portfolio), a separate Trust. 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 Trusts' custodian and is evaluated
daily to ensure that its market value exceeds the delivery value of the
repurchase agreement at maturity.

The repurchase agreements that were executed by the joint account and
outstanding as of September 30, 2004 are as follows:

======================================================================================================


As of September 30, 2004, the collateral for the repurchase agreements in the
joint account was 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

7. 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. Bank acts as the
agent, and other approved registered broker dealers act as the borrowers. The
Trust receives cash collateral, valued at 102% of the value of the securities on
loan, which is initially held in a segregated account at U.S. Bank. As agent,
U.S. Bank 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. Bank. Under the terms of the Trust's securities lending
agreement with U.S. Bank, cash collateral may be invested by U.S. Bank in
certain high quality, liquid investments. At September 30, 2004, the pooled cash
collateral investments consisted of repurchase agreements (41.98%), commercial
paper (27.65%), fixed income notes (24.41%), corporate bonds (5.95%) and mutual
funds (0.01%). 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.

At September 30, 2004 the following funds participated in securities lending and
received cash collateral:

                                                                        VALUE OF

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

DEAR SHAREHOLDER:

The U.S. economy reached a more mature phase of the business cycle during the
six-month period ending September 30, 2004. This phenomenon was marked by lower
realized and forecasted gross domestic product (GDP) growth rates, reduced
forecasts for future corporate earnings growth and a cumulative reported one
million jobs created during the period. The Federal Reserve (Fed), observing
these changes, raised the Fed Funds rate three times between June 30 and
September 21. Inflation, as measured both by the Consumer Price Index (+1.7%)
and Producer Price Index (+1.9%), rose during this time period.

Equity markets moved in a tight trading range over the period. Most broad-based
equity indices ended the period with slightly negative returns. The S&P 500(R)
Index was down slightly, returning -0.18% over the period. Large-cap stocks
tended to outperform small-cap stocks and the S&P 500 outperformed the S&P
MidCap 400(TM) and Russell 2000(R) indices, which returned -1.15% and -2.40%,
respectively. Political and economic uncertainty led investors to return to the
relative safety of large-cap stocks. The S&P 500 also outperformed the Nasdaq
100 Index(R), which posted a return of -1.79%.

There was good news, though. Between the end of March and September, the
unemployment rate experienced a slight decline, moving from 5.6% to 5.4%. The
improvement was driven in part by a 2.8% rebound in manufacturing payrolls.

RYDEX CORE EQUITY FUND

During the last two quarters, the S&P 500 meandered in an extremely tight
trading range (+2% to -5%) before finishing the period down 0.18%. A lack of
strong conviction in market direction was also seen in VIX, a measure of market
volatility, as it decreased over 20% in the last half of the year. Growth
outperformed value (1.5% vs. 0.3%) in the second quarter, but those roles
reversed (-5.5% vs. 0.8%) in the third quarter. During the last two quarters,
the Russell 3000 Value Index was up 1.12% while the Russell 3000 Growth Index
was down 4.06%. Unfortunately, Rydex Core Equity Fund H-Class (-1.18%) was
unable to brave all of these style influences and ended up underperforming the
Russell 3000 Index (-0.59%) by 0.59%.

RYDEX SECTOR ROTATION FUND

On the backs of oil prices--which increased almost 40% in the last six
months--the energy sector (+19.4%) greatly outperformed the S&P 500. Industrials
finished a distant second, up 8.4%. Other sectors that performed well included
basic materials, which was up 6.2%, telecommunication services (+5.4%) and
utilities (+5.1%). Information technology and consumer staples experienced some
difficult times, finishing down 7.3% and down 5.1%, respectively. Health care
(-2.8%), financials (-2%) and consumer discretionary (-1.5%) also underperformed
the S&P 500.

Though five sectors had positive returns and five sectors had negative returns,
investors should not assume that sector investing was flat. Not only was the
spread between the best and worst sector (26.7%) fairly large, but the sectors
that outperformed only represent 27% of the S&P 500's market capitalization.

Rydex Sector Rotation Fund H-Class, which uses a momentum strategy to pick the
best industries in which to invest, underperformed the S&P 500 by 3.55% despite
having a large overweight in the energy sector. The underperformance was largely
due to a non-trending range market that rendered momentum strategies temporarily
ineffective.

As always, we appreciate the trust you have placed in our firm's quality and
integrity by investing with us.

Sincerely,


/s/ CARL G. VERBONCOEUR

Carl G. Verboncoeur
President

ABOUT SHAREHOLDERS FUND'S EXPENSES
- --------------------------------------------------------------------------------

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 may incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments, reinvested
dividends, or other distributions; redemption fees; and exchange fees; and (2)
ongoing costs, including management fees, administrative services, and
shareholder reports, among others. Operating expenses, which are deducted from a
fund's gross income, 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, 2004 and
ending September 30, 2004.

The following table illustrates your fund's costs in two ways:

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."

      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.

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. In addition, 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 example is useful in
      making comparisons because the Securities Exchange Commission 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.

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.

22 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT


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

1. SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Funds (the "Trust") is registered with the Securities and
Exchange Commission 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 six separate classes
of shares, Investor Class Shares, Advisor Class Shares, A-Class Shares, C-Class
Shares, H-Class Shares and Institutional Class Shares. 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. C-Class Shares have a 1% Contingent Deferred Sales
Charge ("CDSC") if shares are redeemed within 12 months of purchase. 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% Contingent
Deferred Sales Charge ("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
AMOUNT OF INVESTMENT                         OFFERING PRICE     AMOUNT INVESTED
- --------------------------------------------------------------------------------
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%
Greater than $1,000,000                           0.00%              0.00%

At September 30, 2004, the Trust consisted of forty-three separate series:
twenty-two Benchmark Funds, one Money Market Fund, eighteen Sector Funds, and
two Strategic Funds. This report covers the Strategic Funds (the "Funds"), while
the Money Market Fund, the Benchmark Funds and the Sector Funds are contained in
separate reports. As of September 30, 2004, only A-Class, C-Class and H-Class
Shares had been issued in the Strategic Funds.

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 their last bid price.
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 is 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.

Short-term securities, if any, are valued at amortized cost, which approximates
market value. Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under
direction of the Board of Trustees or by the Advisor using methods established
or ratified by the Board of Trustees.

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. 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 to shareholders 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.

E. Each Strategic Fund seeks long-term capital appreciation and to respond to
the dynamically changing economy by moving its investments among different
sectors or industries. The Funds may also purchase ADRs and U.S. Government
securities, enter into repurchase agreements, and engage in futures, options and
equity swap transactions. The risks inherent in the use of futures, options and
equity swap agreements include 1) adverse changes in the value of such
instruments; 2) imperfect correlation between the price of the instruments and
movements in the price of the underlying securities; 3) the possible absence of
a liquid secondary market for any particular instrument at any time; and 4) the
potential of counterparty default.

F. 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

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

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, 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.

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 equity swaps involves risks that are different from those associated
with ordinary portfolio securities transactions. Swap agreements may be
considered to be illiquid. Although a fund 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.

In conjunction with the use of options, futures, options on futures and 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 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, and swap agreements include 1) adverse changes in the value of such
instruments; 2) imperfect correlation between the price of the instruments and
movements in the price of the underlying securities, indices, or futures
contracts; 3) the possible absence of a liquid secondary market for any
particular instrument at any time; and 4) the potential of counterparty default.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of an investment advisory contract, the Trust pays Rydex Global
Advisors, 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. Effective July 1, 2003, the Trustees voted to reduce Core Equity's base
management fee to 0.70% of the Fund's average daily net assets and implement a
performance adjustment, adding or subtracting a performance rate up to 0.20%,
allowing 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(R) 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 beginning June 30, 2004. At September 30, 2004, the effective
management fee was 0.90% of the Fund's average daily net assets. Certain
officers and trustees of the Trust are also officers of Rydex Global Advisors.

Rydex Fund Services, Inc. (the "Servicer"), 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
Strategic Funds.

The Servicer 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 Strategic Funds.
Certain officers and trustees of the Trust are also officers of Rydex Fund
Services, Inc.

The Trust has adopted a Distribution Plan (the "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 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.


24 | THE RYDEX SERIES FUNDS SEMI-ANNUAL REPORT



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

The Trust has adopted a separate Distribution and Shareholder Services Plan (the
"C-Class Plan") applicable to its C-Class Shares that allows the Funds to pay
annual distribution and service fees of 1.00% of the Fund's 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 on-going sales commission. The
Distributor advances the first year's service and distribution fees to your
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 Rydex Distributors, Inc.

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
the utilization of earnings and profits distributed to shareholders on
redemption of shares as part of the dividends paid deduction for income tax
purposes, net operating losses not utilized during the current year, and
differences in the treatment of certain notional principal contracts. 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.

TAX BASIS UNREALIZED GAIN (LOSS) ON INVESTMENTS AND DISTRIBUTIONS

At September 30, 2004, 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:

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. Bank acts as the
agent, and other approved registered broker dealers act as the borrowers. The
Trust receives cash collateral, valued at 102% of the value of the securities on
loan, which is initially held in a segregated account at U.S. Bank. As agent,
U.S. Bank 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. Bank. Under the terms of the Trust's securities lending
agreement with U.S. Bank, cash collateral may be invested by U.S. Bank in
certain high quality, liquid investments. At September 30, 2004, the pooled cash
collateral investments consisted of repurchase agreements (41.98%), commercial
paper (27.65%), fixed income notes (24.41%), corporate bonds (5.95%) and mutual
funds (0.01%). 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.

At September 30, 2004 the following funds participated in securities lending and
received cash collateral:

                                                                        VALUE OF
