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

DEAR SHAREHOLDER:

The equity market rise that began shortly after the depths of the financial
crisis in 2008 continued through the six months ending April 30, 2011. Investors
appeared hopeful the economic recovery was becoming self-sustaining, in spite of
an assortment of first quarter 2011 shocks that ranged from higher oil prices to
turmoil in the Mid East to the effects of the natural disaster in Japan.
Assurance from the Fed that it was not going to immediately reverse its loose
monetary policy, and that inflation was transitory, helped drive stocks at
April's end to their highest level since just before the Lehman Brothers
collapse in September 2008.

Clouding the picture, however, were reports of a slower rate of U.S. output and
uncertainty over the expected conclusion of the Fed's quantitative easing
program in June. The infusion of liquidity helped stocks rise 30% since last
August and 20% over six months ending in April. As investors searching for
higher yields increasingly took on credit risk over the past year, many bond
sectors also benefited, particularly investment grade corporate bonds and high-
yield bonds. Yields on the benchmark 10-year Treasury, meanwhile, have been
sliding since December, reflecting increasingly weaker economic data and the
potential for Treasuries to benefit from the end of the Fed's bond buying. In
April, Standard & Poor's cut its outlook for U.S. sovereign debt for the first
time since it started rating it 70 years ago, highlighting the hit to U.S.
creditworthiness brought about by unfunded government tax cuts and spending
programs, along with fiscal stimulus during the recession that have added
significantly to the nation's debt.

April meeting minutes revealed that the Fed's next moves to maintain the economy
would be to reduce its balance sheet and then consider whether to begin raising
rates. But it also indicated it was in no hurry to make a move, particularly
since it believed the recent run-up in commodity prices would not lead to a
sustained increase in inflation. It has held short-term rates near zero since
December 2008.

Some analysts believe the end of quantitative easing could lead to more caution
in the markets, a view supported by weaker-than-expected U.S. GDP figures in
late April that showed the economy grew at an annual rate of 1.8% in the first
quarter of 2011, compared with estimates of around 2%. The rate was 3.1% for the
fourth quarter of 2010. Although some corners of the economy are showing
strength, such as job creation and export growth, stronger gains may be needed
to help encourage households to spend freely. Unemployment remains stubbornly
high at around 9%, while the prices of houses keep falling and sales are down,
keeping consumers on edge.

Investors in global markets, meanwhile, are increasingly concerned about the
potential for soaring food and energy prices to derail global economic recovery.
The International Monetary Fund said global economic growth would slow to 4.5%
this year, down from 5% last year. Through the first four months of 2011, stocks
in overseas developed markets have risen less than counterparts in the U.S.,
while emerging markets stocks have also underperformed. Central banks throughout
the emerging world have begun hiking rates in an effort to slow inflation, while
China has been tapping the brakes on too-fast growth in its economy. Such moves
contributed to a slowing in commodity price rises at the beginning of May, after
a rapid rise over the prior 12 months.

The price of a barrel of oil rose above $100 in the first quarter of 2011 for
the first time since 2008. The higher price of oil as a production cost caused
the prices of many metals to slip in early 2011, aided by a pullback in demand
due to the Japanese earthquake or China's efforts to slow lending. Gold spent
much of the first quarter of 2011 in negative territory, but has turned in a
spectacular climb over the past 12 months, rising above $1,500 an ounce in mid-
April for the first time. Gold traders said bullion bets have increased as
investors question central banks' ability to successfully manage the withdrawal
of stimulus policies put in place during the financial crisis.

Helped largely by the Fed's liberal monetary policy, the dollar has lost value
against most every other global currency over the past few months, as the value
of the dollar against a basket of other currencies fell to a four-decade low.
Some strategists believe the dollar may be poised to rally, benefiting from
hints at possible Fed tightening.

U.S. economic growth, while not robust, has proven strong enough to overcome
some major shocks in the past year. Many market observers, citing recent data on
unemployment, housing and inflation, say the economy remains fragile. Others
believe the economy is moving into a more mature phase and will continue to
expand, although at a lower level than is customary after a major recession.
Despite indicators of slowing in the U.S. and Europe, a new recession in Japan
and renewed worries about sovereign debt in the eurozone, equity markets are
still being buoyed by solid earnings, reasonable valuations and accommodative
monetary policy.

FEES AND EXPENSES (Unaudited)
--------------------------------------------------------------------------------

SHAREHOLDER EXPENSE EXAMPLE
As a shareholder of the Rydex ETF Trust, you incur transaction costs such as
creation and redemption fees or brokerage charges, and ongoing costs including
advisory fees, trustee fees and, if applicable, distribution fees. All other
Trust expenses are paid by the advisor. This Example is intended to help you
understand your ongoing costs (in dollars) of investing in a Fund and to compare
these costs with the ongoing costs of investing in other mutual funds.

The example in the table is based on an investment of $1,000 invested on October
31, 2010 and held for the six months ended April 30, 2011.

ACTUAL EXPENSES
The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you incurred 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 in the first
table under the heading entitled "Expenses Paid During the Six-Month Period" to
estimate the expenses attributable to your investment during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second table below provides information about hypothetical account values
and hypothetical expenses based on a Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not a Fund's actual
return. Thus, you should not use the hypothetical account values and expenses to
estimate the actual ending account balance or your expenses for the period.
Rather, these figures are provided to enable you to compare the ongoing costs of
investing in a Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as creation
and redemption fees, or brokerage charges. Therefore, the second table is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these transaction costs
were included, your costs would have been higher.

PREMIUM AND DISCOUNT INFORMATION (Unaudited)
--------------------------------------------------------------------------------

The tables that follow present information about the differences between the
daily market price on secondary markets for shares of the Funds and each Fund's
NAV. Net Asset Value, or "NAV," is the price per share at which a Fund issues
and redeems shares. It is calculated in accordance with the standard formula for
valuing mutual fund shares. The "Market Price" of a Fund generally is determined
using the midpoint between the highest bid and the lowest offer on the Exchange
on which the Fund is listed for trading, as of the time the Fund's NAV is
calculated. A Fund's Market Price may be at, above or below its NAV. The NAV of
a Fund will fluctuate with changes in the market value of its portfolio
holdings. The Market Price of a Fund will fluctuate in accordance with changes
in its NAV, as well as market supply of and demand for shares of the Funds.

Premiums or discounts are the differences (generally expressed as a percentage)
between the NAV and Market Price of a Fund on a given day, generally at the time
NAV is calculated. A premium is the amount that a Fund is trading above the
reported NAV, expressed as a positive percentage of the NAV. A discount is the
amount that a Fund is trading below the reported NAV, expressed as a negative
percentage of the NAV.

The following information shows the frequency distribution of premiums and
discounts for the Funds. The information shown for each Fund is for the period
from inception to April 30, 2011.

Each line in the table shows the number of trading days in which the Funds
traded within the premium/discount range indicated. The number of trading days
in each premium/discount range is also shown as a percentage of the total number
of trading days in the period covered by the table. All data presented here
represents past performance, which cannot be used to predict future results.

NOTES TO FINANCIAL STATEMENTS (Unaudited)                         April 30, 2011
--------------------------------------------------------------------------------

1.  ORGANIZATION

Rydex ETF Trust (the "Trust") is an open-end, management investment company
registered under the Investment Company Act of 1940 (the "1940 Act"). The Trust
was organized as a Delaware statutory trust on November 22, 2002. As of April
30, 2011, the Trust offers twenty-five portfolios, each of which represents a
separate series of beneficial interest in the Trust (each a "Fund", and
collectively, the "Funds"). The financial statements herein relate to the
following funds: Rydex S&P 500 Equal Weight ETF and Rydex Russell Top 50 ETF.
Rydex S&P 500 Equal Weight ETF commenced operations on April 24, 2003 and the
Rydex Russell Top 50 ETF commenced operations on May 4, 2005.

The Funds' investment objective is to replicate as closely as possible, before
fees and expenses, the daily performance of an index representing publicly
traded equity securities (the "Underlying Index"). Rydex S&P 500 Equal Weight
ETF tracks the S&P 500 Equal Weight Total Return Index. Rydex Russell Top 50 ETF
tracks the Russell Top 50(TM) Index. The Funds seek to achieve their objective
by investing in common stocks that comprise the Underlying Index. The Funds use
a "replication" strategy to track the Underlying Index. "Replication" refers to
investing in substantially all of the securities in the Underlying Index in
approximately the same proportions as in the Underlying Index.

The Funds operate as index funds and are not actively managed. Adverse
performance of a security in the Funds' portfolio will ordinarily not result in
the elimination of the security from the Funds' portfolio.

The Funds issue and redeem shares on a continuous basis, at Net Asset Value per
share ("NAV"), only in aggregation of 50,000 shares called a "Creation Unit".
Creation Units are issued and redeemed principally in-kind for securities
included in the Underlying Index.

2.  SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and
disclosures at the date of the financial statements and accompanying notes and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Management believes that the estimates utilized in
preparing the Funds' financial statements are reasonable and prudent; however,
actual results could differ from these estimates.

A. SECURITY VALUATION

Securities listed on a domestic securities exchange are valued based on the last
sale price as of the close of regular trading hours on the New York Stock
Exchange ("NYSE") or, in the absence of recorded sales, are valued at the most
recent bid price. Securities for which the primary market is the National
Association of Securities Dealers Automated Quotations National Market System
("NASDAQ") are valued at the NASDAQ Official Closing Price. The Funds invest in
money market mutual funds, which are valued at their NAV.

Securities, for which market quotations are not readily available, including
investments that are subject to limitations as to their sale, are valued at fair
value as determined in good faith by Security Global Investors, an affiliated
entity, which acts as the Funds' investment advisor (the "Advisor"), in
accordance with procedures adopted by the Board of Trustees. In determining fair
value, consideration is given to market conditions, relative benchmarks and
other financial data.

B. SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are recorded on the trade date for financial reporting
purposes. Realized gains and losses from portfolio fund transactions are
calculated on the identified cost basis. Dividend income is recorded on the ex-
dividend date, net of foreign tax withholdings. Interest income is recorded on
the accrual basis. Distributions received from investments in real estate
investment trusts ("REITs") are recorded as dividend income on the ex-dividend
date, subject to reclassification upon notice of the character of such
distribution by the issuer.

C. REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements with financial institutions. In a
repurchase agreement, a Fund buys a security and the seller simultaneously
agrees to repurchase the security on a specified future date at an agreed-upon
price. The repurchase price reflects an agreed-upon interest rate during the
time the Fund's money is invested in the security. Because the security
constitutes collateral for the repurchase obligation, a repurchase agreement can
be considered a collateralized loan. The Funds follow certain procedures
designed to minimize the risks inherent in such agreements. These procedures
include effecting repurchase transactions only with



22



NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)             April 30, 2011
--------------------------------------------------------------------------------



large, well-capitalized and well-established financial institutions whose
condition will be continually monitored by Security Global Investors. In
addition, the value of the collateral underlying the repurchase agreement will
always be at least equal to the repurchase price, including any accrued interest
earned on the repurchase agreement. In the event of a default or bankruptcy by a
selling financial institution, the Funds will seek to liquidate such collateral.
However, the exercising of the Funds right to liquidate such collateral could
involve certain costs or delays and, to the extent that proceeds from any sale
upon a default of the obligation to repurchase were less than the repurchase
price, the Funds could suffer a loss. It is the current policy of the Funds not
to invest in repurchase agreements that do not mature within seven days if any
such investment, together with any other illiquid assets held by the Funds,
amounts to more than 15% of the Funds net assets. The investments of the Funds
in repurchase agreements, at times, may be substantial when, in the view of
Security Global Investors, liquidity or other considerations so warrant. For the
six months ended April 30, 2011, the Funds had not engaged in repurchase
agreement transactions.

D. FEDERAL INCOME TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of the
taxable income and capital gains, if any, to the shareholders within the
allowable time limits. Therefore, no provision for Federal income taxes is
required.

Tax positions taken or expected to be taken in the course of preparing the
Funds' tax returns are evaluated 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. Management has
analyzed the Funds' tax positions taken on Federal income tax returns for all
open tax years (fiscal years 2007 -- 2010), and has concluded that no provision
for income tax was required in the Funds' financial statements.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from U.S. generally accepted accounting
principles. These differences are primarily due to differing treatments for in-
kind redemptions, income reclassifications from REITs and losses deferred due to
wash sales.

For the six months ended April 30, 2011, the Funds realized net capital gains
resulting from in-kind redemptions and other transactions. Because gains from
in-kind redemptions are non-taxable to the Funds, and are not distributed to
existing Fund shareholders, the gains are reclassified from accumulated net
realized gains to paid-in-capital at the end of the Funds' tax year. These
reclassifications have no effect on net assets or NAV. The in-kind net capital
gains for the period ended April 30, 2011 are disclosed in the Fund's Statement
of Operations.

At April 30, 2011, the identified cost of investments in securities owned by
each Fund for Federal income tax purposes and the gross unrealized appreciation
and depreciation were as follows:

</Table>


E. FAIR VALUE MEASUREMENT

In accordance with U.S. generally accepted accounting principles, fair value is
defined as the price that the Fund would receive to sell an investment or pay to
transfer a liability in an orderly transaction with an independent buyer in the
principal market, or in the absence of a principal market the most advantageous
market for the investment or liability. A three-tier hierarchy is utilized to
distinguish between (1) inputs that reflect the assumptions market participants
would use in pricing an asset or liability developed based on market data
obtained from sources independent of the reporting entity (observable inputs)
and (2) inputs that reflect the reporting entity's own assumptions about the
assumptions market participants would use in pricing an asset or liability
developed based on the best information available in the circumstances
(unobservable inputs) and to establish classification of fair value measurements
for disclosure purposes. Various inputs are used in determining the value of the
Funds' investments. The inputs are summarized in the three broad levels listed
below:

     Level 1 -- quoted prices in active markets for identical securities. The
     types of assets and liabilities carried at Level 1 fair value generally are
     government and agency securities, equities listed in active markets and
     stock index futures.



                                                      SEMI-ANNUAL REPORT      23




NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)             April 30, 2011
--------------------------------------------------------------------------------


     Level 2 -- other significant observable inputs (including quoted prices for
     similar securities, interest rates, prepayment speeds, credit risk, etc.).
     The types of assets and liabilities carried at Level 2 fair value generally
     are domestic equity index swaps and short term securities with maturities
     of 60 days or less, including repurchase agreements.

     Level 3 -- significant unobservable inputs (including the fund's own
     assumptions used to determine the fair value of investments).

Transfers between investment Levels may occur as the markets fluctuate and/or
the availability of data used in an investment's valuation changes. The inputs
or methodologies used for valuing securities are not necessarily an indication
of the risk associated with investing in those securities.

The following table summarizes the inputs used to value the Funds' net assets as
of April 30, 2011:

Rydex Russell Top 50 ETF................     384,000,454         --              --           384,000,454
</Table>


For the six months ended April 30, 2011, there were no Level 3 Investments.

The Funds disclose information about transfers in and out of all Levels of the
fair value hierarchy on a gross basis and the reasons for the transfers as well
as to disclosures about the valuation techniques and inputs used to measure fair
value for investments that fall in either Level 2 or Level 3 fair value
hierarchy. Purchases, sales, issuances and settlements are shown on a gross
basis in a Level 3 roll forward rather than as one net number.

For the six months ended April 30, 2011, there were no securities transferred
between any levels.

F. DIVIDENDS AND DISTRIBUTIONS

Distributions of net investment income and net realized capital gains, if any,
are declared at least annually and recorded on the ex-dividend date and are
determined in accordance with income tax regulations which may differ from U.S.
generally accepted accounting principles.

G. RISK AND UNCERTAINTIES

The Funds invest in various investments which are exposed to risk, such as
market risk. Due to the level of risk associated with certain investments it is
at least reasonably possible that changes in the values of investment securities
will occur in the near term and that such changes could materially affect
amounts reported in the financial statements. The Rydex Russell Top 50 ETF is a
non-diversified fund, subjecting it to a greater risk than a fund that is
diversified.

H. RISK DISCLOSURE

Throughout 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 their affiliates that have not yet occurred. However, based on experience
the Funds expect the risk of loss to be remote.

3.  ADVISORY, ADMINISTRATION AND OTHER TRANSACTIONS WITH AFFILIATES

The Advisor determines the composition of the portfolio of securities that must
be delivered in exchange for the issuance of Creation Units and periodically
adjusts the composition of the portfolio of the Funds to conform to changes in
the composition of the relevant index. For these services, the Advisor receives
a management fee at the annual rate shown below of the average daily net assets
of the Funds.

The Advisor pays all expenses of the Funds, including the cost of transfer
agency, custody, fund administration, legal, audit and other services, except:
interest, taxes, distribution fees or expenses and extraordinary expenses.

Under an Administration Agreement, State Street Bank and Trust Company (the
"Administrator") provides various administrative and accounting services for the
maintenance and operations of the Funds. Under a Custodian Agreement with the
Trust, the Administrator maintains cash, securities and other assets of the
Trust and the Funds in separate accounts for each Fund, keeps all necessary
accounts and records, and provides other services. The Administrator is
required, upon the order of the Trust, to deliver securities held by the
Custodian and to make payments for securities purchased by the Trust for the
Funds. Pursuant to a Transfer Agency and Service Agreement with the Trust, the
Administrator acts as a transfer agent for the Trust's authorized and issued
shares of beneficial interest, and as dividend disbursing agent of the Trust.
The Advisor compensates the Administrator directly for the foregoing services.

The Funds have adopted a Distribution Plan (the "Plan") that allows the Funds to
pay distribution fees to Rydex Distributors, LLC, an affiliated entity, (the
"Distributor") and other firms that provide distribution services ("Service
Providers"). If a Service Provider provides distribution services, the 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 of the 1940 Act. The
Distributor will, in turn, pay the Service Provider out of its fees. No such fee
is currently charged to the Funds.

Clearing Corporation usual clearing process or for cash. Such transactions are
generally permitted on an in-kind basis, with a balancing cash component to
equate the transaction to the NAV of the Fund on the transaction date.

In May 2011, the Financial Accounting Standards Board issued an Accounting
Standards Update (ASU 2011-4), Amendments to Achieve Common Fair Value
Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which introduces
new disclosure requirements and clarifies certain existing disclosure

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

DEAR SHAREHOLDER:

The equity market rise that began shortly after the depths of the financial
crisis in 2008 continued through the six months ending April 30, 2011. Investors
appeared hopeful the economic recovery was becoming self-sustaining, in spite of
an assortment of first quarter 2011 shocks that ranged from higher oil prices to
turmoil in the Mid East to the effects of the natural disaster in Japan.
Assurance from the Fed that it was not going to immediately reverse its loose
monetary policy, and that inflation was transitory, helped drive stocks at
April's end to their highest level since just before the Lehman Brothers
collapse in September 2008.

Clouding the picture, however, were reports of a slower rate of U.S. output and
uncertainty over the expected conclusion of the Fed's quantitative easing
program in June. The infusion of liquidity helped stocks rise 30% since last
August and 20% over six months ending in April. As investors searching for
higher yields increasingly took on credit risk over the past year, many bond
sectors also benefited, particularly investment grade corporate bonds and high-
yield bonds. Yields on the benchmark 10-year Treasury, meanwhile, have been
sliding since December, reflecting increasingly weaker economic data and the
potential for Treasuries to benefit from the end of the Fed's bond buying. In
April, Standard & Poor's cut its outlook for U.S. sovereign debt for the first
time since it started rating it 70 years ago, highlighting the hit to U.S.
creditworthiness brought about by unfunded government tax cuts and spending
programs, along with fiscal stimulus during the recession that have added
significantly to the nation's debt.

April meeting minutes revealed that the Fed's next moves to maintain the economy
would be to reduce its balance sheet and then consider whether to begin raising
rates. But it also indicated it was in no hurry to make a move, particularly
since it believed the recent run-up in commodity prices would not lead to a
sustained increase in inflation. It has held short-term rates near zero since
December 2008.

Some analysts believe the end of quantitative easing could lead to more caution
in the markets, a view supported by weaker-than-expected U.S. GDP figures in
late April that showed the economy grew at an annual rate of 1.8% in the first
quarter of 2011, compared with estimates of around 2%. The rate was 3.1% for the
fourth quarter of 2010. Although some corners of the economy are showing
strength, such as job creation and export growth, stronger gains may be needed
to help encourage households to spend freely. Unemployment remains stubbornly
high at around 9%, while the prices of houses keep falling and sales are down,
keeping consumers on edge.

Investors in global markets, meanwhile, are increasingly concerned about the
potential for soaring food and energy prices to derail global economic recovery.
The International Monetary Fund said global economic growth would slow to 4.5%
this year, down from 5% last year. Through the first four months of 2011, stocks
in overseas developed markets have risen less than counterparts in the U.S.,
while emerging markets stocks have also underperformed. Central banks throughout
the emerging world have begun hiking rates in an effort to slow inflation, while
China has been tapping the brakes on too-fast growth in its economy. Such moves
contributed to a slowing in commodity price rises at the beginning of May, after
a rapid rise over the prior 12 months.

The price of a barrel of oil rose above $100 in the first quarter of 2011 for
the first time since 2008. The higher price of oil as a production cost caused
the prices of many metals to slip in early 2011, aided by a pullback in demand
due to the Japanese earthquake or China's efforts to slow lending. Gold spent
much of the first quarter of 2011 in negative territory, but has turned in a
spectacular climb over the past 12 months, rising above $1,500 an ounce in mid-
April for the first time. Gold traders said bullion bets have increased as
investors question central banks' ability to successfully manage the withdrawal
of stimulus policies put in place during the financial crisis.

Helped largely by the Fed's liberal monetary policy, the dollar has lost value
against most every other global currency over the past few months, as the value
of the dollar against a basket of other currencies fell to a four-decade low.
Some strategists believe the dollar may be poised to rally, benefiting from
hints at possible Fed tightening.

U.S. economic growth, while not robust, has proven strong enough to overcome
some major shocks in the past year. Many market observers, citing recent data on
unemployment, housing and inflation, say the economy remains fragile. Others
believe the economy is moving into a more mature phase and will continue to
expand, although at a lower level than is customary after a major recession.
Despite indicators of slowing in the U.S. and Europe, a new recession in Japan
and renewed worries about sovereign debt in the eurozone, equity markets are
still being buoyed by solid earnings, reasonable valuations and accommodative
monetary policy.

FEES AND EXPENSES (Unaudited)
--------------------------------------------------------------------------------

SHAREHOLDER EXPENSE EXAMPLE
As a shareholder of the Rydex ETF Trust, you incur transaction costs such as
creation and redemption fees or brokerage charges, and ongoing costs including
advisory fees, trustee fees and, if applicable, distribution fees. All other
Trust expenses are paid by the advisor. This Example is intended to help you
understand your ongoing costs (in dollars) of investing in a Fund and to compare
these costs with the ongoing costs of investing in other mutual funds.

The example in the table is based on an investment of $1,000 invested on October
31, 2010 and held for the six months ended April 30, 2011.

ACTUAL EXPENSES
The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you incurred 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 in the first
table under the heading entitled "Expenses Paid During the Six-Month Period" to
estimate the expenses attributable to your investment during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second table below provides information about hypothetical account values
and hypothetical expenses based on a Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not a Fund's actual
return. Thus, you should not use the hypothetical account values and expenses to
estimate the actual ending account balance or your expenses for the period.
Rather, these figures are provided to enable you to compare the ongoing costs of
investing in a Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as creation
and redemption fees, or brokerage charges. Therefore, the second table is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these transaction costs
were included, your costs would have been higher.

*    Expenses are equal to the Fund's annualized expense ratio multiplied by the
     average account value over the period, multiplied by 181/365 (to reflect
     one-half year period).



                                                          SEMI-ANNUAL REPORT   5






PREMIUM AND DISCOUNT INFORMATION (Unaudited)
--------------------------------------------------------------------------------

The tables that follow present information about the differences between the
daily market price on secondary markets for shares of the Funds and each Fund's
NAV. Net Asset Value, or "NAV," is the price per share at which a Fund issues
and redeems shares. It is calculated in accordance with the standard formula for
valuing mutual fund shares. The "Market Price" of a Fund generally is determined
using the midpoint between the highest bid and the lowest offer on the Exchange
on which the Fund is listed for trading, as of the time the Fund's NAV is
calculated. A Fund's Market Price may be at, above or below its NAV. The NAV of
a Fund will fluctuate with changes in the market value of its portfolio
holdings. The Market Price of a Fund will fluctuate in accordance with changes
in its NAV, as well as market supply of and demand for shares of the Funds.

Premiums or discounts are the differences (generally expressed as a percentage)
between the NAV and Market Price of a Fund on a given day, generally at the time
NAV is calculated. A premium is the amount that a Fund is trading above the
reported NAV, expressed as a positive percentage of the NAV. A discount is the
amount that a Fund is trading below the reported NAV, expressed as a negative
percentage of the NAV.

The following information shows the frequency distribution of premiums and
discounts for the Funds. The information shown for each Fund is for the period
from inception to April 30, 2011.

Each line in the table shows the number of trading days in which the Funds
traded within the premium/discount range indicated. The number of trading days
in each premium/discount range is also shown as a percentage of the total number
of trading days in the period covered by the table. All data presented here
represents past performance, which cannot be used to predict future results.

1.  ORGANIZATION

Rydex ETF Trust (the "Trust") is an open-end, management investment company
registered under the Investment Company Act of 1940 (the "1940 Act"). The Trust
was organized as a Delaware statutory trust on November 22, 2002. As of April
30, 2011, the Trust offers twenty-five portfolios, each of which represents a
separate series of beneficial interest in the Trust (each a "Fund", and
collectively, the "Funds"). The financial statements herein relate to the
following Funds: Rydex S&P 500 Pure Value ETF, Rydex S&P 500 Pure Growth ETF,
Rydex S&P MidCap 400 Pure Value ETF, Rydex S&P 400 Pure Growth ETF, Rydex S&P
SmallCap 600 Pure Value ETF, Rydex S&P SmallCap 600 Pure Growth ETF, Rydex S&P
500 Equal Weight Consumer Discretionary ETF, Rydex S&P 500 Equal Weight Consumer
Staples ETF, Rydex S&P 500 Equal Weight Energy ETF, Rydex S&P 500 Equal Weight
Financials ETF, Rydex S&P 500 Equal Weight Health Care ETF, Rydex S&P 500 Equal
Weight Industrials ETF, Rydex S&P 500 Equal Weight Materials ETF, Rydex S&P 500
Equal Weight Technology ETF and Rydex S&P 500 Equal Weight Utilities ETF. Rydex
S&P 500 Pure Value ETF, Rydex S&P 500 Pure Growth ETF, Rydex S&P MidCap 400 Pure
Value ETF, Rydex S&P MidCap 400 Pure Growth ETF, Rydex S&P SmallCap 600 Pure
Value ETF and Rydex S&P SmallCap 600 Pure Growth ETF commenced operations on
March 1, 2006. Rydex S&P 500 Equal Weight Consumer Discretionary ETF, Rydex S&P
500 Equal Weight Consumer Staples ETF, Rydex S&P 500 Equal Weight Energy ETF,
Rydex S&P 500 Equal Weight Financials ETF, Rydex S&P 500 Equal Weight Health
Care ETF, Rydex S&P 500 Equal Weight Industrials ETF, Rydex S&P 500 Equal Weight
Materials ETF, Rydex S&P 500 Equal Weight Technology ETF and Rydex S&P 500 Equal
Weight Utilities ETF commenced operations on November 1, 2006.

The Funds' investment objective is to replicate as closely as possible, before
fees and expenses, the daily performance of an index representing publicly
traded equity securities (the "Underlying Index"). The Rydex S&P 500 Pure Value
ETF tracks the S&P 500 Pure Value Index, the Rydex S&P 500 Pure Growth ETF
tracks the S&P 500 Pure Growth Index, the Rydex S&P MidCap 400 Pure Value ETF
tracks the S&P MidCap 400 Pure Value Index, the Rydex S&P MidCap 400 Pure Growth
ETF tracks the S&P MidCap 400 Pure Growth Index, the Rydex S&P SmallCap 600 Pure
Value ETF tracks the S&P SmallCap 600 Pure Value Index, the Rydex S&P SmallCap
600 Pure Growth ETF tracks the S&P SmallCap 600 Pure Growth Index, the Rydex S&P
500 Equal Weight Consumer Discretionary ETF tracks the S&P 500 Equal Weight
Consumer Discretionary Index, the Rydex S&P 500 Equal Weight Consumer Staples
ETF tracks the S&P 500 Equal Weight Consumer Staples Index, the Rydex S&P 500
Equal Weight Energy ETF tracks the S&P 500 Equal Weight Energy Index, the Rydex
S&P 500 Equal Weight Financials ETF tracks the S&P 500 Equal Weight Financials
Index, the Rydex S&P 500 Equal Weight Health Care ETF tracks the S&P 500 Equal
Weight Health Care Index, the Rydex S&P 500 Equal Weight Industrials ETF tracks
the S&P 500 Equal Weight Industrials Index, the Rydex S&P 500 Equal Weight
Materials ETF tracks the S&P 500 Equal Weight Materials Index, the Rydex S&P 500
Equal Weight Technology ETF tracks the S&P 500 Equal Weight Information
Technology Index and the Rydex S&P 500 Equal Weight Utilities ETF tracks the S&P
500 Equal Weight Telecommunication Services & Utilities Index. The Funds seek to
achieve their objective by investing in common stocks that comprise the
Underlying Index. The Funds use a "replication" strategy to track the Underlying
Index. "Replication" refers to investing in substantially all of the securities
in the Underlying Index in approximately the same proportions as in the
Underlying Index.

The Funds operate as index funds and are not actively managed. Adverse
performance of a security in the Funds' portfolio will ordinarily not result in
the elimination of the security from the Funds' portfolio.

The Funds issue and redeem shares on a continuous basis, at Net Asset Value per
share ("NAV"), only in aggregation of 50,000 shares called a "Creation Unit".
Creation Units are issued and redeemed principally in-kind for securities
included in the Underlying Index.

2.  SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and
disclosures at the date of the financial statements and accompanying notes and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Management believes that the estimates utilized in
preparing the Funds' financial statements are reasonable and prudent; however,
actual results could differ from these estimates.

A. SECURITY VALUATION

Securities listed on a domestic securities exchange are valued based on the last
sale price as of the close of regular trading hours on the New York Stock
Exchange ("NYSE") or, in the absence of recorded sales, are valued at the most
recent bid price. Securities for which the primary market is the National
Association of Securities Dealers Automated Quotations National Market System
("NASDAQ") are valued at the NASDAQ Official Closing Price. The Funds invest in
money market mutual funds, which are valued at their NAV.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)
--------------------------------------------------------------------------------


Securities, for which market quotations are not readily available, including
investments that are subject to limitations as to their sale, are valued at fair
value as determined in good faith by Security Global Investors, an affiliated
entity, which acts as the Funds' investment advisor (the "Advisor"), in
accordance with procedures adopted by the Board of Trustees. In determining fair
value, consideration is given to market conditions, relative benchmarks and
other financial data.

B. SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are recorded on the trade date for financial reporting
purposes. Realized gains and losses from portfolio fund transactions are
calculated on the identified cost basis. Dividend income is recorded on the ex-
dividend date, net of foreign tax withholdings. Interest income is recorded on
the accrual basis. Distributions received from investments in real estate
investment trusts ("REITs") are recorded as dividend income on the ex-dividend
date, subject to reclassification upon notice of the character of such
distribution by the issuer.

C. REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements with financial institutions. In a
repurchase agreement, a Fund buys a security and the seller simultaneously
agrees to repurchase the security on a specified future date at an agreed-upon
price. The repurchase price reflects an agreed-upon interest rate during the
time the Fund's money is invested in the security. Because the security
constitutes collateral for the repurchase obligation, a repurchase agreement can
be considered a collateralized loan. The Funds follow certain procedures
designed to minimize the risks inherent in such agreements. These procedures
include effecting repurchase transactions only with large, well-capitalized and
well-established financial institutions whose condition will be continually
monitored by Security Global Investors. In addition, the value of the collateral
underlying the repurchase agreement will always be at least equal to the
repurchase price, including any accrued interest earned on the repurchase
agreement. In the event of a default or bankruptcy by a selling financial
institution, the Funds will seek to liquidate such collateral. However, the
exercising of the Funds right to liquidate such collateral could involve certain
costs or delays and, to the extent that proceeds from any sale upon a default of
the obligation to repurchase were less than the repurchase price, the Funds
could suffer a loss. It is the current policy of the Funds not to invest in
repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Funds, amounts
to more than 15% of the Funds net assets. The investments of the Funds in
repurchase agreements, at times, may be substantial when, in the view of
Security Global Investors, liquidity or other considerations so warrant. For the
six months ended April 30, 2011, the Funds had not engaged in repurchase
agreement transactions.

D. FEDERAL INCOME TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of the
taxable income and capital gains, if any, to the shareholders within the
allowable time limits. Therefore, no provision for Federal income taxes is
required.

Tax positions taken or expected to be taken in the course of preparing the
Funds' tax returns are evaluated 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. Management has
analyzed the Funds' tax positions taken on Federal income tax returns for all
open tax years (fiscal years 2007 -- 2010), and has concluded that no provision
for income tax was required in the Funds' financial statements.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from U.S. generally accepted accounting
principles. These differences are primarily due to differing treatments for in-
kind redemptions, distributions in excess of current year earnings, excise taxes
paid, income reclassifications from REITs and losses deferred due to wash sales.

For the six months ended April 30, 2011, the Funds realized net capital gains
resulting from in-kind redemptions and other transactions. Because gains from
in-kind redemptions are non-taxable to the Funds, and are not distributed to
existing Fund shareholders, the gains are reclassified from accumulated net
realized gains to paid-in-capital at the end of the Funds' tax year. These
reclassifications have no effect on net assets or NAV. The in-kind net capital
gains for the period ended April 30, 2011 are disclosed in the Fund's Statement
of Operations.

E. FAIR VALUE MEASUREMENT

In accordance with U.S. generally accepted accounting principles, fair value is
defined as the price that the Fund would receive to sell an investment or pay to
transfer a liability in an orderly transaction with an independent buyer in the
principal market, or in the absence of a principal market the most advantageous
market for the investment or liability. A three-tier hierarchy is utilized to
distinguish between (1) inputs that reflect the assumptions market participants
would use in pricing an asset or liability developed based on market data
obtained from sources independent of the reporting entity (observable inputs)
and (2) inputs that reflect the reporting entity's own assumptions about the
assumptions market participants would use in pricing an asset or liability
developed based on the best information available in the circumstances
(unobservable inputs) and to establish classification of fair value measurements
for disclosure purposes. Various inputs are used in determining the value of the
Funds' investments. The inputs are summarized in the three broad levels listed
below:

     Level 1 -- quoted prices in active markets for identical securities. The
     types of assets and liabilities carried at Level 1 fair value generally are
     government and agency securities, equities listed in active markets and
     stock index futures.

     Level 2 -- other significant observable inputs (including quoted prices for
     similar securities, interest rates, prepayment speeds, credit risk, etc.).
     The types of assets and liabilities carried at Level 2 fair value generally
     are domestic equity index swaps and short term securities with maturities
     of 60 days or less, including repurchase agreements.

     Level 3 -- significant unobservable inputs (including the fund's own
     assumptions used to determine the fair value of investments).

Transfers between investment Levels may occur as the markets fluctuate and/or
the availability of data used in an investment's valuation changes. The inputs
or methodologies used for valuing securities are not necessarily an indication
of the risk associated with investing in those securities.

For the six months ended April 30, 2011, there were no Level 3 Investments.

The Funds disclose information about transfers in and out of all Levels of the
fair value hierarchy on a gross basis and the reasons for the transfers as well
as to disclosures about the valuation techniques and inputs used to measure fair
value for investments that fall in either Level 2 or Level 3 fair value
hierarchy. Purchases, sales, issuances and settlements are shown on a gross
basis in a Level 3 roll forward rather than as one net number.

For the six months ended April 30, 2011, there were no securities transferred
between any levels.

F. DIVIDENDS AND DISTRIBUTIONS

Distributions of net investment income and net realized capital gains, if any,
are declared at least annually and recorded on the ex-dividend date and are
determined in accordance with income tax regulations which may differ from U.S.
generally accepted accounting principles.

G. RISK AND UNCERTAINTIES

The Funds invest in various investments which are exposed to risk, such as
market risk. Due to the level of risk associated with certain investments it is
at least reasonably possible that changes in the values of investment securities
will occur in the near term and that such changes could materially affect
amounts reported in the financial statements. The Rydex S&P 500 Equal Weight
Sector ETFs are non-diversified funds, subjecting them to a greater risk than
funds that are diversified.

H. RISK DISCLOSURE

Throughout 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 their affiliates that have not yet occurred. However, based on experience
the Funds expect the risk of loss to be remote.

3.  ADVISORY, ADMINISTRATION AND OTHER TRANSACTIONS WITH AFFILIATES

The Advisor determines the composition of the portfolio of securities that must
be delivered in exchange for the issuance of Creation Units and periodically
adjusts the composition of the portfolio of the Funds to conform to changes in
the composition of the relevant

The Advisor pays all expenses of the Funds, including the cost of transfer
agency, custody, fund administration, legal, audit and other services, except:
interest, taxes, distribution fees or expenses and extraordinary expenses.

Under an Administration Agreement, State Street Bank and Trust Company (the
"Administrator") provides various administrative and accounting services for the
maintenance and operations of the Funds. Under a Custodian Agreement with the
Trust, the Administrator maintains cash, securities and other assets of the
Trust and the Funds in separate accounts for each Fund, keeps all necessary
accounts and records, and provides other services. The Administrator is
required, upon the order of the Trust, to deliver securities held by the
Custodian and to make payments for securities purchased by the Trust for the
Funds. Pursuant to a Transfer Agency and Service Agreement with the Trust, the
Administrator acts as a transfer agent for the Trust's authorized and issued
shares of beneficial interest, and as dividend disbursing agent of the Trust.
The Advisor compensates the Administrator directly for the foregoing services.

The Funds have adopted a Distribution Plan (the "Plan") that allows the Funds to
pay distribution fees to Rydex Distributors, LLC, an affiliated entity, (the
"Distributor") and other firms that provide distribution services ("Service
Providers"). If a Service Provider provides distribution services, the 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 of the 1940 Act. The
Distributor will, in turn, pay the Service Provider out of its fees. No such fee
is currently charged to the Funds.

4.  CAPITAL

At April 30, 2011, there were an unlimited number of no par value shares of
beneficial interest authorized. There is a minimum transaction fee per
transaction to those persons purchasing or redeeming Creation Units. An
additional charge of up to three times the standard transaction fee may be
imposed for purchases and redemptions effected outside the National Securities
Clearing Corporation usual clearing process or for cash. Such transactions are
generally permitted on an in-kind basis, with a balancing cash component to

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

DEAR SHAREHOLDER:

The equity market rise that began shortly after the depths of the financial
crisis in 2008 continued through the six months ending April 30, 2011. Investors
appeared hopeful the economic recovery was becoming self-sustaining, in spite of
an assortment of first quarter 2011 shocks that ranged from higher oil prices to
turmoil in the Mid East to the effects of the natural disaster in Japan.
Assurance from the Fed that it was not going to immediately reverse its loose
monetary policy, and that inflation was transitory, helped drive stocks at
April's end to their highest level since just before the Lehman Brothers
collapse in September 2008.

Clouding the picture, however, were reports of a slower rate of U.S. output and
uncertainty over the expected conclusion of the Fed's quantitative easing
program in June. The infusion of liquidity helped stocks rise 30% since last
August and 20% over six months ending in April. As investors searching for
higher yields increasingly took on credit risk over the past year, many bond
sectors also benefited, particularly investment grade corporate bonds and high-
yield bonds. Yields on the benchmark 10-year Treasury, meanwhile, have been
sliding since December, reflecting increasingly weaker economic data and the
potential for Treasuries to benefit from the end of the Fed's bond buying. In
April, Standard & Poor's cut its outlook for U.S. sovereign debt for the first
time since it started rating it 70 years ago, highlighting the hit to U.S.
creditworthiness brought about by unfunded government tax cuts and spending
programs, along with fiscal stimulus during the recession that have added
significantly to the nation's debt.

April meeting minutes revealed that the Fed's next moves to maintain the economy
would be to reduce its balance sheet and then consider whether to begin raising
rates. But it also indicated it was in no hurry to make a move, particularly
since it believed the recent run-up in commodity prices would not lead to a
sustained increase in inflation. It has held short-term rates near zero since
December 2008.

Some analysts believe the end of quantitative easing could lead to more caution
in the markets, a view supported by weaker-than-expected U.S. GDP figures in
late April that showed the economy grew at an annual rate of 1.8% in the first
quarter of 2011, compared with estimates of around 2%. The rate was 3.1% for the
fourth quarter of 2010. Although some corners of the economy are showing
strength, such as job creation and export growth, stronger gains may be needed
to help encourage households to spend freely. Unemployment remains stubbornly
high at around 9%, while the prices of houses keep falling and sales are down,
keeping consumers on edge.

Investors in global markets, meanwhile, are increasingly concerned about the
potential for soaring food and energy prices to derail global economic recovery.
The International Monetary Fund said global economic growth would slow to 4.5%
this year, down from 5% last year. Through the first four months of 2011, stocks
in overseas developed markets have risen less than counterparts in the U.S.,
while emerging markets stocks have also underperformed. Central banks throughout
the emerging world have begun hiking rates in an effort to slow inflation, while
China has been tapping the brakes on too-fast growth in its economy. Such moves
contributed to a slowing in commodity price rises at the beginning of May, after
a rapid rise over the prior 12 months.

The price of a barrel of oil rose above $100 in the first quarter of 2011 for
the first time since 2008. The higher price of oil as a production cost caused
the prices of many metals to slip in early 2011, aided by a pullback in demand
due to the Japanese earthquake or China's efforts to slow lending. Gold spent
much of the first quarter of 2011 in negative territory, but has turned in a
spectacular climb over the past 12 months, rising above $1,500 an ounce in mid-
April for the first time. Gold traders said bullion bets have increased as
investors question central banks' ability to successfully manage the withdrawal
of stimulus policies put in place during the financial crisis.

Helped largely by the Fed's liberal monetary policy, the dollar has lost value
against most every other global currency over the past few months, as the value
of the dollar against a basket of other currencies fell to a four-decade low.
Some strategists believe the dollar may be poised to rally, benefiting from
hints at possible Fed tightening.

U.S. economic growth, while not robust, has proven strong enough to overcome
some major shocks in the past year. Many market observers, citing recent data on
unemployment, housing and inflation, say the economy remains fragile. Others
believe the economy is moving into a more mature phase and will continue to
expand, although at a lower level than is customary after a major recession.
Despite indicators of slowing in the U.S. and Europe, a new recession in Japan
and renewed worries about sovereign debt in the eurozone, equity markets are
still being buoyed by solid earnings, reasonable valuations and accommodative
monetary policy.

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

The 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.

<Table>

                                     INDEX         INDEX          FUND     FUND          FUND

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)%
----------------------------------------------------------------------------------------------------------

</Table>


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.

Because certain funds seek to track the performance of their benchmark on a
daily basis, mathematical compounding, especially with respect to those funds
that use leverage as part of their investment strategy, may prevent a fund from
correlating with the monthly, quarterly, annual or other period performance of
its benchmark. Due to the compounding of daily returns, leveraged and inverse
funds' returns over periods other than one day will likely differ in amount and
possibly direction from the benchmark return for the same period. Investors
should monitor their leveraged and inverse funds' holdings consistent with their
strategies, as frequently as daily. For those funds that consistently apply
leverage, the value of the fund's shares will tend to increase or decrease more
than the value of any increase or decrease in its benchmark index. For more on
correlation, leverage and other risks, please read the prospectus.

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.

FEES AND EXPENSES (Unaudited)
--------------------------------------------------------------------------------

SHAREHOLDER EXPENSE EXAMPLE
As a shareholder of the Rydex ETF Trust, you incur transaction costs such as
creation and redemption fees or brokerage charges, and ongoing costs including
advisory fees, trustee fees and, if applicable, distribution fees. All other
Trust expenses are paid by the advisor. This Example is intended to help you
understand your ongoing costs (in dollars) of investing in a Fund and to compare
these costs with the ongoing costs of investing in other mutual funds.

The example in the table is based on an investment of $1,000 invested on October
31, 2010 and held for the six months ended April 30, 2011.

ACTUAL EXPENSES
The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you incurred 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 in the first
table under the heading entitled "Expenses Paid During the Six-Month Period" to
estimate the expenses attributable to your investment during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second table below provides information about hypothetical account values
and hypothetical expenses based on a Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not a Fund's actual
return. Thus, you should not use the hypothetical account values and expenses to
estimate the actual ending account balance or your expenses for the period.
Rather, these figures are provided to enable you to compare the ongoing costs of
investing in a Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as creation
and redemption fees, or brokerage charges. Therefore, the second table is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these transaction costs
were included, your costs would have been higher.

PREMIUM AND DISCOUNT INFORMATION (Unaudited)
--------------------------------------------------------------------------------

The tables that follow present information about the differences between the
daily market price on secondary markets for shares of the Funds and each Fund's
NAV. Net Asset Value, or "NAV," is the price per share at which a Fund issues
and redeems shares. It is calculated in accordance with the standard formula for
valuing mutual fund shares. The "Market Price" of a Fund generally is determined
using the midpoint between the highest bid and the lowest offer on the Exchange
on which the Fund is listed for trading, as of the time the Fund's NAV is
calculated. A Fund's Market Price may be at, above or below its NAV. The NAV of
a Fund will fluctuate with changes in the market value of its portfolio
holdings. The Market Price of a Fund will fluctuate in accordance with changes
in its NAV, as well as market supply of and demand for shares of the Funds.

Premiums or discounts are the differences (generally expressed as a percentage)
between the NAV and Market Price of a Fund on a given day, generally at the time
NAV is calculated. A premium is the amount that a Fund is trading above the
reported NAV, expressed as a positive percentage of the NAV. A discount is the
amount that a Fund is trading below the reported NAV, expressed as a negative
percentage of the NAV.

The following information shows the frequency distribution of premiums and
discounts for the Funds. The information shown for each Fund is for the period
from inception to April 30, 2011.

Each line in the table shows the number of trading days in which the Funds
traded within the premium/discount range indicated. The number of trading days
in each premium/discount range is also shown as a percentage of the total number
of trading days in the period covered by the table. All data presented here
represents past performance, which cannot be used to predict future results.

NOTES TO FINANCIAL STATEMENTS (Unaudited)                         April 30, 2011
--------------------------------------------------------------------------------

1.  ORGANIZATION

Rydex ETF Trust (the "Trust") is an open-end, management investment company
registered under the Investment Company Act of 1940 (the "1940 Act"). The Trust
was organized as a Delaware statutory trust on November 22, 2002. As of April
30, 2011, the Trust offers twenty-five portfolios, each of which represents a
separate series of beneficial interest in the Trust (each a "Fund", and
collectively, the "Funds"). The financial statements herein relate to the
following Funds: Rydex 2x S&P 500 ETF and Rydex Inverse 2x S&P 500 ETF. Rydex 2x
S&P 500 ETF and Rydex Inverse 2x S&P 500 ETF commenced operations on November 5,
2007.

The Funds' investment objective is to replicate as closely as possible, before
fees and expenses, the daily performance of an index representing publicly
traded equity securities (the "Underlying Index"). The Funds' investment
objective is to provide investment results that match the performance of a
specific benchmark, before fees and expenses, on a daily basis. For Rydex 2x S&P
500 ETF (a "Leveraged Fund"), the Fund's benchmark is 200% of the daily
performance of an index representing publicly traded securities (the "Underlying
Index"). For Rydex Inverse 2x S&P 500 ETF (a "Leveraged Inverse Fund"), the
Fund's benchmark is 200% of the daily inverse (opposite) performance of its
Underlying Index. The Underlying Index for Rydex 2x S&P 500 ETF and Rydex
Inverse 2x S&P 500 ETF is the S&P 500 Index.

The Funds operate as index funds and are not actively managed. Adverse
performance of a security in the Funds' portfolio will ordinarily not result in
the elimination of the security from the Funds' portfolio.

The Funds issue and redeem shares on a continuous basis, at Net Asset Value per
share ("NAV"), only in aggregation of 50,000 shares called a "Creation Unit".
Creation Units are issued and redeemed principally in-kind for securities
included in the Underlying Index.

2.  SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and
disclosures at the date of the financial statements and accompanying notes and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Management believes that the estimates utilized in
preparing the Funds' financial statements are reasonable and prudent; however,
actual results could differ from these estimates.

A. SECURITY VALUATION

Securities listed on a domestic securities exchange are valued based on the last
sale price as of the close of regular trading hours on the New York Stock
Exchange ("NYSE") or, in the absence of recorded sales, are valued at the most
recent bid price. Securities for which the primary market is the National
Association of Securities Dealers Automated Quotations National Market System
("NASDAQ") are valued at the NASDAQ Official Closing Price. The Funds invest in
money market mutual funds, which are valued at their NAV.

Investments for which market quotations are not readily available are fair
valued as determine in good faith by Security Global Investors, an affiliated
entity, which acts as the Funds' investment advisor, under the 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 instruments, 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 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 on the valuation date. In
the event that the exchange for a specific futures contract closes earlier than
4:00 p.m., 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. to determine if fair valuation
would provide a more accurate valuation.

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 the close the NYSE. The swap's market value is then
adjusted to include dividends accrued, financing charges and/or interest
associated with the swap agreements.



                                                          SEMI-ANNUAL REPORT  21





NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)
--------------------------------------------------------------------------------


Debt securities with a maturity greater than 60 days are valued at the last
traded fill price at the close of business, unless no trades were executed. If
there are no trades, a security is valued at the reported bid price at the close
of business. Short-term debt securities, with a maturity of 60 days or less, are
valued at amortized cost which approximates market value.

Certain U.S. Government and Agency Obligations are traded on a discount basis;
the interest rates shown on the Schedules of Investments reflect the effective
rates paid at the time of purchase by the Funds. Other securities bear interest
at the rates shown, payable at fixed dates through maturity. The Funds may also
purchase American Depository Receipts, U.S. Government securities, and enter
into repurchase agreements.

B. SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are recorded on the trade date for financial reporting
purposes. Realized gains and losses from portfolio fund transactions are
calculated on the identified cost basis. Dividend income is recorded on the ex-
dividend date, net of foreign tax withholdings. Interest income is recorded on
the accrual basis. Distributions received from investments in real estate
investment trusts ("REITs") are recorded as dividend income on the ex-dividend
date, subject to reclassification upon notice of the character of such
distribution by the issuer.

C. REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements with financial institutions. In a
repurchase agreement, a Fund buys a security and the seller simultaneously
agrees to repurchase the security on a specified future date at an agreed-upon
price. The repurchase price reflects an agreed-upon interest rate during the
time the Fund's money is invested in the security. Because the security
constitutes collateral for the repurchase obligation, a repurchase agreement can
be considered a collateralized loan. The Funds follow certain procedures
designed to minimize the risks inherent in such agreements. These procedures
include effecting repurchase transactions only with large, well-capitalized and
well-established financial institutions whose condition will be continually
monitored by Security Global Investors. In addition, the value of the collateral
underlying the repurchase agreement will always be at least equal to the
repurchase price, including any accrued interest earned on the repurchase
agreement. In the event of a default or bankruptcy by a selling financial
institution, the Funds will seek to liquidate such collateral. However, the
exercising of the Funds right to liquidate such collateral could involve certain
costs or delays and, to the extent that proceeds from any sale upon a default of
the obligation to repurchase were less than the repurchase price, the Funds
could suffer a loss. It is the current policy of the Funds not to invest in
repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Funds, amounts
to more than 15% of the Funds net assets. The investments of the Funds in
repurchase agreements, at times, may be substantial when, in the view of
Security Global Investors, liquidity or other considerations so warrant.

D. FUTURES CONTRACTS

The Funds utilized stock index futures contracts to gain exposure to the
Underlying Index. Futures contracts are contracts for delayed delivery of
securities at a specified futures 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. There are
several risks in connection with the use of futures contracts. 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. Since futures are exchange-traded and the
exchange's clearinghouse, as counterparty to all exchange traded futures,
guarantees the futures against default, there is minimal counterparty credit
risk to the Funds.

E. SWAP AGREEMENTS

The Funds utilized domestic equity index swap agreements to gain exposure to the
Underlying Index, 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 index, in return for periodic payment based on a fixed or variable
interest rate. Swap agreements are used to obtain exposure to an equity or
market without owning or taking physical custody of securities. The swap
agreements are marked-to-market daily based upon quotations from market makers
and the change, if any, is recorded as unrealized gain or loss. Payments
received or made as a result of



22




NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)
--------------------------------------------------------------------------------



an agreement or termination of the agreement are recognized as realized gains or
losses. There are several risks associated with the use of swap agreements that
are different from those associated with ordinary portfolio securities
transactions, due to the fact they could be considered illiquid. Since swaps are
not exchange-traded, there is an element of counterparty credit risk to the
Funds. The risk is managed through the terms of the swap contracts which include
trigger points to terminate the current contract based on predetermined
thresholds and limit the amount of potential loss. Although the Trust will not
enter into any swap agreement unless Security Global Investors 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.

F. COLLATERAL

In conjunction with the use of short sales, futures and swap agreements, 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 repurchase agreements allocated to each
Fund.

G. FEDERAL INCOME TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of the
taxable income and capital gains, if any, to the shareholders within the
allowable time limits. Therefore, no provision for Federal income taxes is
required.

Tax positions taken or expected to be taken in the course of preparing the
Funds' tax returns are evaluated 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. Management has
analyzed the Funds' tax positions taken on Federal income tax returns for all
open tax years (fiscal years 2008 -- 2010), and has concluded that no provision
for income tax was required in the Funds' financial statements.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from U.S. generally accepted accounting
principles. These differences are primarily due to differing treatments for in-
kind redemptions, mark-to-market on futures contracts, income reclassifications
from REITs and losses deferred due to wash sales.

For the six months ended April 30, 2011, the Funds realized net capital gains
resulting from in-kind redemptions and other transactions. Because gains from
in-kind redemptions are non-taxable to the Funds, and are not distributed to
existing Fund shareholders, the gains are reclassified from accumulated net
realized gains to paid-in-capital at the end of the Funds' tax year. These
reclassifications have no effect on net assets or NAV. The in-kind net capital
gains for the period ended April 30, 2011 are disclosed in the Fund's Statement
of Operations.

At April 30, 2011, the identified cost of investments in securities owned by
each Fund for Federal income tax purposes and the gross unrealized appreciation
and depreciation were as follows:

H. FAIR VALUE MEASUREMENT

In accordance with U.S. generally accepted accounting principles, fair value is
defined as the price that the Fund would receive to sell an investment or pay to
transfer a liability in an orderly transaction with an independent buyer in the
principal market, or in the absence of a principal market the most advantageous
market for the investment or liability. A three-tier hierarchy is utilized to
distinguish between (1) inputs that reflect the assumptions market participants
would use in pricing an asset or liability developed based on market data
obtained from sources independent of the reporting entity (observable inputs)
and (2) inputs that reflect the reporting entity's own assumptions about the
assumptions market participants would use in pricing an asset or liability
developed based on the best information available in the circumstances
(unobservable inputs) and to establish classification of fair value measurements
for disclosure



                                                          SEMI-ANNUAL REPORT  23





NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

purposes. Various inputs are used in determining the value of the Funds'
investments. The inputs are summarized in the three broad levels listed below:

     Level 1 -- quoted prices in active markets for identical securities. The
     types of assets and liabilities carried at Level 1 fair value generally are
     government and agency securities, equities listed in active markets and
     stock index futures.

     Level 2 -- other significant observable inputs (including quoted prices for
     similar securities, interest rates, prepayment speeds, credit risk, etc.).
     The types of assets and liabilities carried at Level 2 fair value generally
     are domestic equity index swaps and short term securities with maturities
     of 60 days or less, including repurchase agreements.

     Level 3 -- significant unobservable inputs (including the fund's own
     assumptions used to determine the fair value of investments).

Transfers between investment Levels may occur as the markets fluctuate and/or
the availability of data used in an investment's valuation changes. The inputs
or methodologies used for valuing securities are not necessarily an indication
of the risk associated with investing in those securities.

The following table summarizes the inputs used to value the Funds' net assets as
of April 30, 2011:

</Table>


For the six months ended April 30, 2011, there were no Level 3 Investments.

The Funds disclose information about transfers in and out of all Levels of the
fair value hierarchy on a gross basis and the reasons for the transfers as well
as to disclosures about the valuation techniques and inputs used to measure fair
value for investments that fall in either Level 2 or Level 3 fair value
hierarchy. Purchases, sales, issuances and settlements are shown on a gross
basis in a Level 3 roll forward rather than as one net number.

For the six months ended April 30, 2011, there were no securities transferred
between any levels.

I. DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

U.S. generally accepted accounting principles require disclosures to enable
investors to better understand how and why the Funds use derivative instruments,
how these derivative instruments are accounted for and their effects on the
Funds' financial position and results of operations. None of the derivatives
currently held by the Funds are being used as hedging instruments.

During the period ended April 30, 2011, the Funds sought to gain part, if not
all, exposure to their respective benchmarks by investing in financial-linked
derivative instruments, including swap agreements and futures. The following
table represents the notional amount of derivative instruments outstanding, as
an approximate percentage of the Funds' net assets on a daily basis, while the
risk to the Fund is limited to the profit earned on such derivatives.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)
--------------------------------------------------------------------------------


J. DIVIDENDS AND DISTRIBUTIONS

Distributions of net investment income and net realized capital gains, if any,
are declared at least annually and recorded on the ex-dividend date and are
determined in accordance with income tax regulations which may differ from U.S.
generally accepted accounting principles.

K. RISK AND UNCERTAINTIES

The Funds invest in various investments which are exposed to risk, such as
market risk. Due to the level of risk associated with certain investments it is
at least reasonably possible that changes in the values of investment securities
will occur in the near term and that such changes could materially affect
amounts reported in the financial statements. The risk inherent in the use of
futures and options contracts, and swap agreements, 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. The Funds have established strict counterparty credit
guidelines and enter into transactions only with financial institutions of
investment grade or better. The Trust monitors the counterparty credit risk.

L. RISK DISCLOSURE

Throughout 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 their affiliates that have not yet occurred. However, based on experience
the Funds expect the risk of loss to be remote.

3.  ADVISORY, ADMINISTRATION AND OTHER TRANSACTIONS WITH AFFILIATES

The Advisor determines the composition of the portfolio of securities that must
be delivered in exchange for the issuance of Creation Units and periodically
adjusts the composition of the portfolio of the Funds to conform to changes in
the composition of the relevant index. For these services, the Advisor receives
a management fee at the annual rate shown below of the average daily net assets
of the Funds.

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

Rydex Inverse 2x S&P 500 ETF........................................      0.70%
</Table>


The Advisor pays all expenses of the Funds, including the cost of transfer
agency, custody, fund administration, legal, audit and other services, except:
interest, taxes, distribution and trustee fees or expenses and extraordinary
expenses.

Under an Administration Agreement, State Street Bank and Trust Company (the
"Administrator") provides various administrative and accounting services for the
maintenance and operations of the Funds. Under a Custodian Agreement with the
Trust, the Administrator maintains cash, securities and other assets of the
Trust and the Funds in separate accounts for each Fund, keeps all necessary
accounts and records, and provides other services. The Administrator is
required, upon the order of the Trust, to deliver securities held by the
Custodian and to make payments for securities purchased by the Trust for the
Funds. Pursuant to a Transfer Agency and Service Agreement with the Trust, the
Administrator acts as a transfer agent for the Trust's authorized and issued
shares of beneficial interest, and as dividend disbursing agent of the Trust.
The Advisor compensates the Administrator directly for the foregoing services.

The Funds have adopted a Distribution Plan (the "Plan") that allows the Funds to
pay distribution fees to Rydex Distributors, LLC, an affiliated entity, (the
"Distributor") and other firms that provide distribution services ("Service
Providers"). If a Service Provider provides distribution services, the 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 of the 1940 Act. The
Distributor will, in turn, pay the Service Provider out of its fees. No such fee
is currently charged to the Funds.

4.  CAPITAL

At April 30, 2011, there were an unlimited number of no par value shares of
beneficial interest authorized. There is a minimum transaction fee per
transaction to those persons purchasing or redeeming Creation Units. An
additional charge of up to three times the standard transaction fee may be
imposed for purchases and redemptions effected outside the National Securities
Clearing Corporation

6.  NEW ACCOUNTING PRONOUNCEMENT

In May 2011, the Financial Accounting Standards Board issued an Accounting
Standards Update (ASU 2011-4), Amendments to Achieve Common Fair Value
Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which introduces
new disclosure requirements and clarifies certain existing disclosure
requirements around fair value measurements currently presented in Note H. The
new disclosures and clarifications of existing disclosures are generally
effective during interim and annual periods beginning after December 15, 2011.
Management is evaluating the impact of this update on its current disclosures.

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

DEAR SHAREHOLDER:

The equity market rise that began shortly after the depths of the financial
crisis in 2008 continued through the six months ending April 30, 2011. Investors
appeared hopeful the economic recovery was becoming self-sustaining, in spite of
an assortment of first quarter 2011 shocks that ranged from higher oil prices to
turmoil in the Mid East to the effects of the natural disaster in Japan.
Assurance from the Fed that it was not going to immediately reverse its loose
monetary policy, and that inflation was transitory, helped drive stocks at
April's end to their highest level since just before the Lehman Brothers
collapse in September 2008.

Clouding the picture, however, were reports of a slower rate of U.S. output and
uncertainty over the expected conclusion of the Fed's quantitative easing
program in June. The infusion of liquidity helped stocks rise 30% since last
August and 20% over six months ending in April. As investors searching for
higher yields increasingly took on credit risk over the past year, many bond
sectors also benefited, particularly investment grade corporate bonds and high-
yield bonds. Yields on the benchmark 10-year Treasury, meanwhile, have been
sliding since December, reflecting increasingly weaker economic data and the
potential for Treasuries to benefit from the end of the Fed's bond buying. In
April, Standard & Poor's cut its outlook for U.S. sovereign debt for the first
time since it started rating it 70 years ago, highlighting the hit to U.S.
creditworthiness brought about by unfunded government tax cuts and spending
programs, along with fiscal stimulus during the recession that have added
significantly to the nation's debt.

April meeting minutes revealed that the Fed's next moves to maintain the economy
would be to reduce its balance sheet and then consider whether to begin raising
rates. But it also indicated it was in no hurry to make a move, particularly
since it believed the recent run-up in commodity prices would not lead to a
sustained increase in inflation. It has held short-term rates near zero since
December 2008.

Some analysts believe the end of quantitative easing could lead to more caution
in the markets, a view supported by weaker-than-expected U.S. GDP figures in
late April that showed the economy grew at an annual rate of 1.8% in the first
quarter of 2011, compared with estimates of around 2%. The rate was 3.1% for the
fourth quarter of 2010. Although some corners of the economy are showing
strength, such as job creation and export growth, stronger gains may be needed
to help encourage households to spend freely. Unemployment remains stubbornly
high at around 9%, while the prices of houses keep falling and sales are down,
keeping consumers on edge.

Investors in global markets, meanwhile, are increasingly concerned about the
potential for soaring food and energy prices to derail global economic recovery.
The International Monetary Fund said global economic growth would slow to 4.5%
this year, down from 5% last year. Through the first four months of 2011, stocks
in overseas developed markets have risen less than counterparts in the U.S.,
while emerging markets stocks have also underperformed. Central banks throughout
the emerging world have begun hiking rates in an effort to slow inflation, while
China has been tapping the brakes on too-fast growth in its economy. Such moves
contributed to a slowing in commodity price rises at the beginning of May, after
a rapid rise over the prior 12 months.

The price of a barrel of oil rose above $100 in the first quarter of 2011 for
the first time since 2008. The higher price of oil as a production cost caused
the prices of many metals to slip in early 2011, aided by a pullback in demand
due to the Japanese earthquake or China's efforts to slow lending. Gold spent
much of the first quarter of 2011 in negative territory, but has turned in a
spectacular climb over the past 12 months, rising above $1,500 an ounce in mid-
April for the first time. Gold traders said bullion bets have increased as
investors question central banks' ability to successfully manage the withdrawal
of stimulus policies put in place during the financial crisis.

Helped largely by the Fed's liberal monetary policy, the dollar has lost value
against most every other global currency over the past few months, as the value
of the dollar against a basket of other currencies fell to a four-decade low.
Some strategists believe the dollar may be poised to rally, benefiting from
hints at possible Fed tightening.

U.S. economic growth, while not robust, has proven strong enough to overcome
some major shocks in the past year. Many market observers, citing recent data on
unemployment, housing and inflation, say the economy remains fragile. Others
believe the economy is moving into a more mature phase and will continue to
expand, although at a lower level than is customary after a major recession.
Despite indicators of slowing in the U.S. and Europe, a new recession in Japan
and renewed worries about sovereign debt in the eurozone, equity markets are
still being buoyed by solid earnings, reasonable valuations and accommodative
monetary policy.

FEES AND EXPENSES (Unaudited)
--------------------------------------------------------------------------------

SHAREHOLDER EXPENSE EXAMPLE
As a shareholder of the Rydex ETF Trust, you incur transaction costs such as
creation and redemption fees or brokerage charges, and ongoing costs including
advisory fees, trustee fees and, if applicable, distribution fees. All other
Trust expenses are paid by the advisor. This Example is intended to help you
understand your ongoing costs (in dollars) of investing in a Fund and to compare
these costs with the ongoing costs of investing in other mutual funds.

The example in the table is based on an investment of $1,000 invested on the
commencement date and held for the period ended April 30, 2011.

ACTUAL EXPENSES
The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you incurred 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 in the first
table under the heading entitled "Expenses Paid During the Six-Month Period" to
estimate the expenses attributable to your investment during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second table below provides information about hypothetical account values
and hypothetical expenses based on a Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not a Fund's actual
return. Thus, you should not use the hypothetical account values and expenses to
estimate the actual ending account balance or your expenses for the period.
Rather, these figures are provided to enable you to compare the ongoing costs of
investing in a Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as creation
and redemption fees, or brokerage charges. Therefore, the second table is useful
in comparing ongoing costs only, and will not help you determine the relative
total costs of owning different funds. In addition, if these transaction costs
were included, your costs would have been higher.

PREMIUM AND DISCOUNT INFORMATION (Unaudited)
--------------------------------------------------------------------------------

The tables that follow present information about the differences between the
daily market price on secondary markets for shares of the Funds and each Fund's
NAV. Net Asset Value, or "NAV," is the price per share at which a Fund issues
and redeems shares. It is calculated in accordance with the standard formula for
valuing mutual fund shares. The "Market Price" of a Fund generally is determined
using the midpoint between the highest bid and the lowest offer on the Exchange
on which the Fund is listed for trading, as of the time the Fund's NAV is
calculated. A Fund's Market Price may be at, above or below its NAV. The NAV of
a Fund will fluctuate with changes in the market value of its portfolio
holdings. The Market Price of a Fund will fluctuate in accordance with changes
in its NAV, as well as market supply of and demand for shares of the Funds.

Premiums or discounts are the differences (generally expressed as a percentage)
between the NAV and Market Price of a Fund on a given day, generally at the time
NAV is calculated. A premium is the amount that a Fund is trading above the
reported NAV, expressed as a positive percentage of the NAV. A discount is the
amount that a Fund is trading below the reported NAV, expressed as a negative
percentage of the NAV.

The following information shows the frequency distribution of premiums and
discounts for the Funds. The information shown for each Fund is for the period
from inception to April 30, 2011.

Each line in the table shows the number of trading days in which the Funds
traded within the premium/discount range indicated. The number of trading days
in each premium/discount range is also shown as a percentage of the total number
of trading days in the period covered by the table. All data presented here
represents past performance, which cannot be used to predict future results.

NOTES TO FINANCIAL STATEMENTS (Unaudited)                         April 30, 2011
--------------------------------------------------------------------------------

1.  ORGANIZATION

Rydex ETF Trust (the "Trust") is an open-end, management investment company
registered under the Investment Company Act of 1940 (the "1940 Act"). The Trust
was organized as a Delaware statutory trust on November 22, 2002. As of April
30, 2011, the Trust offers twenty-five portfolios, each of which represents a
separate series of beneficial interest in the Trust (each a "Fund", and
collectively, the "Funds"). The financial statements herein relate to the
following funds: Rydex Russell MidCap Equal Weight ETF, Rydex Russell 1000(R)
Equal Weight ETF, Rydex Russell 2000(R) Equal Weight ETF, Rydex MSCI EAFE Equal
Weight ETF, Rydex MSCI Emerging Markets Equal Weight ETF and Rydex MSCI ACWI
Equal Weight ETF. Rydex Russell MidCap Equal Weight ETF, Rydex Russell 1000(R)
Equal Weight ETF, Rydex Russell 2000(R) Equal Weight ETF, Rydex MSCI EAFE Equal
Weight ETF and Rydex MSCI Emerging Markets Equal Weight ETF commenced operations
on December 3, 2010 and the Rydex MSCI ACWI Equal Weight ETF commenced
operations on January 7, 2011.

The Funds' investment objective is to replicate as closely as possible, before
fees and expenses, the daily performance of an index representing publicly
traded equity securities (the "Underlying Index"). Rydex Russell MidCap Equal
Weight ETF tracks the Russell MidCap Equal Weight Index, the Rydex Russell
1000(R) Equal Weight ETF tracks the Russell 1000(R) Equal Weight Index, the
Rydex Russell 2000(R) Equal Weight ETF tracks the Russell 2000(R) Equal Weight
Index, the Rydex MSCI EAFE Equal Weight ETF tracks the MSCI EAFE Equal Weighted
Index, the Rydex MSCI Emerging Markets Equal Weight ETF tracks the MSCI Emerging
Markets Equal Weighted Index and the Rydex MSCI ACWI Equal Weight ETF tracks the
MSCI ACWI Equal Weighted Index. The Funds seek to achieve their objective by
investing in common stocks or ETFs, where applicable, that comprise the
Underlying Index. The Funds use a "replication" strategy to track the Underlying
Index. Replication refers to investing in substantially all of the securities in
the Underlying Index in approximately the same proportions as in the Underlying
Index.

The Funds operate as index funds and are not actively managed. Adverse
performance of a security in the Funds' portfolio will ordinarily not result in
the elimination of the security from the Funds' portfolio.

The Funds issue and redeem shares on a continuous basis, at Net Asset Value per
share ("NAV"), only in aggregation of 50,000 shares called a "Creation Unit".
Creation Units are issued and redeemed principally in-kind for securities
included in the Underlying Index.

2.  SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and
disclosures at the date of the financial statements and accompanying notes and
the reported amounts of increases and decreases in net assets from operations
during the reporting period. Management believes that the estimates utilized in
preparing the Funds' financial statements are reasonable and prudent; however,
actual results could differ from these estimates.

Securities listed on a domestic securities exchange are valued based on the last
sale price as of the close of regular trading hours on the New York Stock
Exchange ("NYSE") or, in the absence of recorded sales, are valued at the most
recent bid price. Securities for which the primary market is the National
Association of Securities Dealers Automated Quotations National Market System
("NASDAQ") are valued at the NASDAQ Official Closing Price. The Funds invest in
money market mutual funds, which are valued at their NAV.

Securities, for which market quotations are not readily available, including
investments that are subject to limitations as to their sale, are valued at fair
value as determined in good faith by Security Global Investors, an affiliated
entity, which acts as the Funds' investment advisor (the "Advisor"), in
accordance with procedures adopted by the Board of Trustees. In determining fair
value, consideration is given to market conditions, relative benchmarks and
other financial data.

If events occur after the close of a foreign exchange that will affect the value
of a Fund's portfolio securities before the time as of which the NAV is
calculated (a "significant event"), the security will generally be priced using
a fair value procedure. If the Valuation Committee determines a significant
event has occurred, it will evaluate the impact of that event on an affected
security or securities, to determine whether a fair value adjustment would
materially affect the Funds' NAV. Some of the factors which may be considered by
the Board of Trustees in determining fair value are fundamental analytical data
relating to the investment, the nature and duration of any restrictions on
disposition, trading in similar securities of the same issuer or comparable
companies, information from broker-dealers, and an evaluation of the forces that
influence the market in which the securities are purchased and sold.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)
--------------------------------------------------------------------------------


Generally, trading in foreign securities markets is substantially completed each
day at various times prior to the close of the NYSE. The values of foreign
securities are determined as of the close of such foreign markets or the close
of the NYSE, if earlier. All investments quoted in foreign currency are valued
in U.S. dollars on the basis of the foreign currency exchange rates prevailing
at the close of business. Investments in foreign securities may involve risks
not present in domestic investments. The Valuation Committee will determine the
current value of such foreign securities by taking into consideration certain
factors which may include those discussed above, as well as the following
factors, among others: the value of the securities traded on other foreign
markets, ADR trading, closed-end fund trading, foreign currency exchange
activity, and the trading prices of financial products that are tied to foreign
securities such as WEBS(R). In addition, the Board of Trustees has authorized
the Valuation Committee and Administrator to use prices and other information
supplied by a third party pricing vendor in valuing foreign securities.

Debt securities with a maturity greater than 60 days are valued at the last
traded fill price at the close of business, unless no trades were executed. If
there are no trades, a security is valued at the reported bid price at the close
of business. Short-term debt securities, with a maturity of 60 days or less, are
valued at amortized cost which approximates market value.

B. SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are recorded on the trade date for financial reporting
purposes. Realized gains and losses from portfolio fund transactions are
calculated on the identified cost basis. Dividend income is recorded on the ex-
dividend date, net of foreign tax withholdings. Interest income is recorded on
the accrual basis. Distributions received from investments in real estate
investment trusts ("REITs") are recorded as dividend income on the ex-dividend
date, subject to reclassification upon notice of the character of such
distribution by the issuer.

C. REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements with financial institutions. In a
repurchase agreement, a Fund buys a security and the seller simultaneously
agrees to repurchase the security on a specified future date at an agreed-upon
price. The repurchase price reflects an agreed-upon interest rate during the
time the Fund's money is invested in the security. Because the security
constitutes collateral for the repurchase obligation, a repurchase agreement can
be considered a collateralized loan. The Funds follow certain procedures
designed to minimize the risks inherent in such agreements. These procedures
include effecting repurchase transactions only with large, well-capitalized and
well-established financial institutions whose condition will be continually
monitored by Security Global Investors. In addition, the value of the collateral
underlying the repurchase agreement will always be at least equal to the
repurchase price, including any accrued interest earned on the repurchase
agreement. In the event of a default or bankruptcy by a selling financial
institution, the Funds will seek to liquidate such collateral. However, the
exercising of the Funds right to liquidate such collateral could involve certain
costs or delays and, to the extent that proceeds from any sale upon a default of
the obligation to repurchase were less than the repurchase price, the Funds
could suffer a loss. It is the current policy of the Funds not to invest in
repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Funds, amounts
to more than 15% of the Funds net assets. The investments of the Funds in
repurchase agreements, at times, may be substantial when, in the view of
Security Global Investors, liquidity or other considerations so warrant. For the
period ended April 30, 2011, the Funds had not engaged in repurchase agreement
transactions.

D. FOREIGN CURRENCY TRANSACTIONS

The accounting records of the Funds are maintained in U.S. dollars. All assets
and liabilities initially expressed in foreign currencies are converted into
U.S. dollars at prevailing exchange rates. Purchases and sales of investment
securities, dividend and interest income, and certain expenses are translated at
the rates of exchange prevailing on the respective dates of such transactions.
Changes in the relationship of these foreign currencies to the U.S. dollar can
significantly affect the value of the investments and earnings of the Funds.
Foreign investments may also subject the Fund to foreign government exchange
restrictions, expropriation, taxation or other political, social or economic
developments, all of which could affect the market and/or credit risk of the
investments.

The Funds do not isolate that portion of the results of operations resulting
from changes in the foreign exchange rates on investments from the fluctuations
arising from changes in the market prices of securities held. Such fluctuations
are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of portfolio
securities, sales of foreign currencies, and the difference between asset and
liability amounts initially stated in foreign currencies and the U.S. dollar
value of the amounts actually received or



                                                          SEMI-ANNUAL REPORT  87





NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)
--------------------------------------------------------------------------------



paid. Net unrealized foreign exchange gains or losses arise from changes in the
value of portfolio securities and other assets and liabilities at the end of the
reporting period, resulting from changes in the exchange rates.

E. FEDERAL INCOME TAXES

The Funds' policy is to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of the
taxable income and capital gains, if any, to the shareholders within the
allowable time limits. Therefore, no provision for Federal income taxes is
required.

Tax positions taken or expected to be taken in the course of preparing the
Funds' tax returns are evaluated 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. Management has
analyzed the Funds' tax positions taken on Federal income tax returns for all
open tax years (fiscal year 2010), and has concluded that no provision for
income tax was required in the Funds' financial statements.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from U.S. generally accepted accounting
principles. These differences are primarily due to differing treatments for in-
kind redemptions, distributions in excess of current year earnings, excise taxes
paid, income reclassifications from REITs and losses deferred due to wash sales.

For the period ended April 30, 2011, the Funds realized net capital gains
resulting from in-kind redemptions and other transactions. Because gains from
in-kind redemptions are not-taxable to the Funds, and are not distributed to
existing Fund shareholders, the gains are reclassified from accumulated net
realized gains to paid-in-capital at the end of the Funds' tax year. These
reclassifications have no effect on net assets or NAV. The in-kind net capital
gains for the period ended April 30, 2011 are disclosed in the Fund's Statement
of Operations.

At April 30, 2011, the identified cost of investments in securities owned by
each Fund for Federal income tax purposes and the gross unrealized appreciation
and depreciation were as follows:

F. FAIR VALUE MEASUREMENT

In accordance with U.S. generally accepted accounting principles, fair value is
defined as the price that the Fund would receive to sell an investment or pay to
transfer a liability in an orderly transaction with an independent buyer in the
principal market, or in the absence of a principal market the most advantageous
market for the investment or liability. A three-tier hierarchy is utilized to
distinguish between (1) inputs that reflect the assumptions market participants
would use in pricing an asset or liability developed based on market data
obtained from sources independent of the reporting entity (observable inputs)
and (2) inputs that reflect the reporting entity's own assumptions about the
assumptions market participants would use in pricing an asset or liability
developed based on the best information available in the circumstances
(unobservable inputs) and to establish classification of fair value measurements
for disclosure purposes. Various inputs are used in determining the value of the
Funds' investments. The inputs are summarized in the three broad levels listed
below:

     Level 1 -- quoted prices in active markets for identical securities. The
     types of assets and liabilities carried at Level 1 fair value generally are
     government and agency securities, equities listed in active markets and
     stock index futures.

     Level 2 -- other significant observable inputs (including quoted prices for
     similar securities, interest rates, prepayment speeds, credit risk, etc.).
     The types of assets and liabilities carried at Level 2 fair value generally
     are domestic equity index swaps and short term securities with maturities
     of 60 days or less, including repurchase agreements.

     Level 3 -- significant unobservable inputs (including the fund's own
     assumptions used to determine the fair value of investments).

Transfers between investment Levels may occur as the markets fluctuate and/or
the availability of data used in an investment's valuation changes. The inputs
or methodologies used for valuing securities are not necessarily an indication
of the risk associated with investing in those securities.

The Funds disclose information about transfers in and out of all Levels of the
fair value hierarchy on a gross basis and the reasons for the transfers as well
as to disclosures about the valuation techniques and inputs used to measure fair
value for investments that fall in either Level 2 or Level 3 fair value
hierarchy. Purchases, sales, issuances and settlements are shown on a gross
basis in a Level 3 roll forward rather than as one net number.

For the period ended April 30, 2011, there were no securities transferred
between any levels.

G. DIVIDENDS AND DISTRIBUTIONS

Distributions of net investment income and net realized capital gains, if any,
are declared at least annually and recorded on the ex-dividend date and are
determined in accordance with income tax regulations which may differ from U.S.
generally accepted accounting principles.

H. RISK AND UNCERTAINTIES

The Funds invest in various investments which are exposed to risk, such as
market risk. Due to the level of risk associated with certain investments it is
at least reasonably possible that changes in the values of investment securities
will occur in the near term and that such changes could materially affect
amounts reported in the financial statements.

I. RISK DISCLOSURE

Throughout 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 their affiliates that have not yet occurred. However, based on experience
the Funds expect the risk of loss to be remote.

3.  ADVISORY, ADMINISTRATION AND OTHER TRANSACTIONS WITH AFFILIATES

The Advisor determines the composition of the portfolio of securities that must
be delivered in exchange for the issuance of Creation Units and periodically
adjusts the composition of the portfolio of the Funds to conform to changes in
the composition of the relevant index. For these services, the Advisor receives
a management fee at the annual rate shown below of the average daily net assets
of the Funds.

The Advisor pays all expenses of the Funds, including the cost of transfer
agency, custody, fund administration, legal, audit and other services, except:
interest, taxes, distribution and trustee fees or expenses and extraordinary
expenses.

Under an Administration Agreement, State Street Bank and Trust Company (the
"Administrator") provides various administrative and accounting services for the
maintenance and operations of the Funds. Under a Custodian Agreement with the
Trust, the Administrator maintains cash, securities and other assets of the
Trust and the Funds in separate accounts for each Fund, keeps all necessary
accounts and records, and provides other services. The Administrator is
required, upon the order of the Trust, to deliver securities held by the
Custodian and to make payments for securities purchased by the Trust for the
Funds. Pursuant to a Transfer Agency and Service Agreement with the Trust, the
Administrator acts as a transfer agent for the Trust's authorized and issued
shares of beneficial interest, and as dividend disbursing agent of the Trust.
The Advisor compensates the Administrator directly for the foregoing services.

The Funds have adopted a Distribution Plan (the "Plan") that allows the Funds to
pay distribution fees to Rydex Distributors, LLC, an affiliated entity, (the
"Distributor") and other firms that provide distribution services ("Service
Providers"). If a Service Provider provides distribution services, the 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 of the 1940 Act. The
Distributor will, in turn, pay the Service Provider out of its fees. No such fee
is currently charged to the Funds.

4.  CAPITAL

At April 30, 2011, there were an unlimited number of no par value shares of
beneficial interest authorized. There is a minimum transaction fee per
transaction to those persons purchasing or redeeming Creation Units. An
additional charge of up to three times the standard transaction fee may be
imposed for purchases and redemptions effected outside the National Securities
Clearing Corporation usual clearing process or for cash. Such transactions are
generally permitted on an in-kind basis, with a balancing cash component to
equate the transaction to the NAV of the Fund on the transaction date.
Transaction fees are not charged to or paid by the Funds. The minimum
transaction fees are:

6. AFFILIATED TRANSACTIONS

Investments representing 5% or more of the outstanding voting shares of a
portfolio company of a fund, or control of or by, or common control under
Guggenheim Partners, LLC, result in that portfolio company being considered an
affiliated company of such fund, as defined in the 1940 Act. Transactions during
the period ended April 30, 2011 in which the portfolio company is an "affiliated
