 SEMI-ANNUAL REPORT 2

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

DEAR SHAREHOLDER,

The period ended April 30 was a positive environment for investors in nearly all
asset classes. Although economic growth in the U.S. showed unmistakable signs of
slowing, that was a positive development for both equity and fixed-income
investors as it mitigated inflationary pressures, allowing interest rates to
fall and take pressure off the Federal Reserve Bank. The global economy, on the
other hand, raced ahead as the rapidly growing economies of Brazil, Russia,
India and China continued their breakneck economic expansions. International
equity markets surged higher and were, once again, one of the most profitable
areas for investors over the past year.

Despite the fact that U.S. equity markets continued to be buffeted by
crosscurrents over high and volatile energy prices and uncertainty about the
future course of monetary policy, equity prices rose strongly during this
period. The bellwether S&P 500(R) Index rose nearly 8.60% on a total return
basis, with the Dow Jones Industrial Average up an even more robust 9.41%.

If there was an overriding theme to domestic equity markets during this period,
it was the ongoing debate over the future direction of interest rates. It is
frequently said that markets climb a wall of worry, and examination of return
patterns bears this out. Investors sought exposure to stocks, but they wanted to
play it safe at the same time. The defensive mindset favored value stocks. With
the possibility of a damaging market reversal present in investors' minds,
inexpensive stocks seemed to be the safer play. The S&P/Citigroup 500 Pure Value
Index, which combines the attributes of both size and low valuations, rose
12.07% compared to a gain of 8.41% for the S&P/Citigroup 600 Small Cap Pure
Growth Index. The 17.93% gain for the S&P 500 Utilities Index -- one of the
strongest of all 10 of the sector indices -- reinforced the defensive
orientation on the part of many investors during the period.

With the pullback in stock prices in late February and early March, equities are
more attractively valued now and have some room to rally going forward. That
said, we think the preference for defense at home and exposure to the rapidly
growing global economy is here for some time to come. Our outlook for stock
prices is further enhanced if the Fed begins to cut interest rates, something we
anticipate, but not until later this year.

We appreciate the trust you have placed in our firm's quality and integrity by
investing with us.

Sincerely,

/s/ DAVID C. REILLY, CFA

 SEMI-ANNUAL REPORT 4

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

SHAREHOLDER EXPENSE EXAMPLE (UNAUDITED)

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 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
November 1, 2006 and held for the six months ended April 30, 2007.

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 the 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.

Telecommunication Services & Utilities. 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,
only in aggregations 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 accounting principles
generally accepted in the United States of America 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 or, in the absence of recorded sales, are valued at the most recent bid
price. Securities for which the

                                                           SEMI-ANNUAL REPORT 83

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

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 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.

On September 15, 2006, the Financial Accounting Standards Board ("FASB")
released Statement of Financial Accounting Standard No. 157 Fair Value
Measurement ("FAS 157") which provided enhanced guidance for using fair value to
measure assets and liabilities. The standard requires companies to provide
expanded information about the assets and liabilities measured at fair value and
the potential effect of these fair valuations on an entity's financial
performance. The standard does not expand the use of fair value in any new
circumstances, but provides clarification on acceptable fair valuation methods
and applications. Adoption of FAS 157 is required for fiscal years beginning
after November 15, 2007. The standard is not expected to materially impact the
Funds' financial statements.

B. SECURITY TRANSACTIONS AND INCOME RECOGNITION

Security transactions are recorded on the trade date. 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.

C. REPURCHASE AGREEMENTS

The Funds may enter into repurchase agreements with financial institutions. The
Funds follows 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 Rydex Global Advisors, which acts as
the Funds' investment advisor (the "Advisor"). 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 the
Advisor, liquidity or other considerations so warrant. For the six months ended
April 30, 2007, the Funds had not engaged in repurchase 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 distribute all of the taxable
income to the shareholders within the allowable time limits. Therefore, no
provision for Federal income taxes is required.

Income and capital gain distributions are determined in accordance with Federal
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. These differences are primarily due to
differing treatments for in-kind redemptions, income reclassifications from real
estate investment trusts ("REITs") and losses deferred due to wash sales.

For the six months ended April 30, 2007, 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 net asset value per share. The
in-kind gains for the six months ended April 30, 2007 are disclosed in the Funds
Statement of Operations.

On July 13, 2006, the FASB released FASB Interpretation No. 48 Accounting for
Uncertainty in Income Taxes ("FIN 48"). FIN 48 provides guidance for how
uncertain tax positions should be recognized, measured, presented and disclosed
in the financial statements. FIN 48 requires the evaluation of tax positions
taken or expected to be taken in the course of preparing the Fund's tax returns
to determine whether the tax positions are "more-likely- than-not" of being
sustained by the applicable tax authority. Tax positions not deemed to meet the
more-likely-than-not threshold would be recorded as a tax benefit or expense in
the current year. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of the
effective date. Recent SEC guidance allows implementing FIN 48 in fund net asset
value calculations as late as a fund's last net asset value calculation in the
first required financial statement reporting period. As a result, the Funds will
incorporate FIN 48 in their semi-annual report on April 30, 2008. At this time,
management is evaluating the implications of FIN 48 and its impact on the
financial statements has not yet been determined.

E. DIVIDENDS AND DISTRIBUTIONS

The Funds declare and pay dividends from net investment income and distribute
from net realized capital gains at least annually.

F. RISK AND UNCERTAINTIES

The Trust invests 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 and
Rydex S&P Equal Weight Sector ETFs are non-diversified funds, subjecting them to
a greater risk than funds that are diversified.

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 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, Inc. (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, 2007, 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

ITEM 11. CONTROLS AND PROCEDURES.

(a) Based on their evaluation on July 5, 2007, the President (principal
executive officer) and the Treasurer (principal financial officer) of the Rydex
ETF Trust (the "Trust") believe that there were no significant deficiencies in
the design or operation of the internal controls of the Trust or Rydex Global

Street Bank and Trust Company (the "Administrator"), the administrator of the
Trust, or Rydex Distributors, Inc. ("RD"), which acts as distributor for the
Trust, including disclosure controls and procedures (as defined in Rule 30a-3(c)
under the Investment Company Act of 1940) which would have adversely affected
the ability of the Trust, the Administrator or RGA on behalf of the Trust, to
record, process, summarize, and report the subject matter contained in this
Report, and the President and Treasurer of the Trust have identified no material
weaknesses in such internal controls on behalf of the Trust.

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

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