DEAR SHAREHOLDER,

Despite strong crosscurrents buffeting stock prices over the six-month period
ending April 30th, the major market averages were able to turn in a strong
performance with the S&P 500(R) Index, gaining 9.6%, followed by the Dow Jones
Industrial Average(SM), which also rose nearly 10.2%. It was a good period for
technology stocks as well, with the Nasdaq 100 Index(R) tacking on a 7.9% gain.
The critical question for investors is whether stocks can sustain this rally and
in the process, break out of the trading range they have been mired in for the
past two years.

From an economic standpoint, there is reason to be cautious. Economic growth
slowed dramatically in the fourth quarter of 2005 to a sub 2% annual rate and
then rebounded strongly in the first quarter of this year to nearly 5%. With the
impact of higher energy prices and interest rates still to be felt, economic
growth is likely to slow to a 2.5% - 3.0% pace as we move further into 2006.
Continued uncertainty over Federal Reserve (Fed) policy, interest rates,
earnings and volatile energy prices also carry the potential to restrain stock
market gains.

Although corporate earnings are still growing at double-digit rates, the pace is
clearly slowing. This has two implications. First, since the market tends to
focus on trends as opposed to absolute levels, slowing earnings growth will be
perceived as a negative. Secondly, as earnings have grown faster than prices,
stocks have become cheaper. This latter development sets the stage for a
possible short-term market rally. In order for stock prices to move higher,
however, two things need to happen. First, energy prices need to stabilize. Oil
rose steadily from approximately $60/bbl in early November to over $73/bbl by
the end of April. This served to trap stocks in a rather familiar
pattern -- when oil moved up, stocks moved down. The other necessary catalyst
for stocks to appreciate is clarity from the Fed on the future direction of
monetary policy.

The Fed raised interest rates three times during the period, moving the closely
watched Fed Funds target rate to 4.75%. Since these moves were widely
anticipated they had little impact on stock prices. More importantly from the
market's perspective, however, was the accompanying commentary which, in March,
left the door open for future rate increases. This shook the consensus that the
Fed would stop raising rates at somewhere between 4.75% and 5.25%. With the
looming possibility of rising interest rates, investors were reluctant to place
higher valuations on stock prices.

Uncertainty over the future course of monetary policy pushed interest rates
higher across the maturity spectrum. By the end of April, yields on 2-year,
5-year and 10-year Treasury obligations had risen to 4.86%, 4.92% and 5.05%
respectively. The relative flatness of the yield curve lent strength to the
argument that economic growth is poised to slow.

Overseas markets, both in developed and developing economies continued to
outperform domestic markets. So, while the U.S. is slowing, overseas economies
are

picking up steam. We expect this to have a favorable effect on U.S. markets.
Industries and companies involved in exporting materials, industrial equipment,
energy, communications and technology services should benefit. On a broader
level, once an end to Fed rate increases is in sight -- something we anticipate
as we move in to the latter half of 2006 -- stocks may embark on a short-term
rally. A decline in energy prices -- something we place a lower probability
on -- could have the same effect. In the short-term, stocks are likely to lack
significant direction until one of these catalysts appears.

SHAREHOLDER EXPENSE EXAMPLE (UNAUDITED)

As a shareholder of the Rydex ETF Trust, you incur advisory fees and
distribution fees. All other Trust expenses are paid by the adviser. 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 is based on an investment of $1,000 invested at the beginning of the
period and held for the six-months ended April 30, 2006.

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.

1.  ORGANIZATION

Rydex ETF Trust (the "Trust") is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"). The Trust was organized as a Delaware statutory trust on November 22,
2002. The Trust currently consists of eight series, Rydex S&P Equal Weight ETF,
Rydex Russell Top 50 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, (the "Funds"). Rydex S&P Equal Weight ETF commenced operations
on April 24, 2003 and Rydex Russell Top 50 ETF commenced operations on May 4,
2005. 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 all
commenced operations on March 1, 2006.

The Funds' investment objective is to provide investment results that correspond
generally to the price and yield performance, before fees and expenses, of an
index representing publicly traded equity securities (the "Underlying Index").
The Rydex S&P Equal Weight ETF tracks the S&P Equal Weight Index, the Rydex
Russell Top 50 ETF tracks the Russell Top 50(TM) Index, the Rydex S&P 500 Pure
Value ETF tracks the S&P 500/Citigroup Pure Value Index, the Rydex S&P 500 Pure
Growth ETF tracks the S&P 500/Citigroup Pure Growth Index, the Rydex S&P MidCap
400 Pure Value ETF tracks the S&P MidCap 400/Citigroup Pure Value Index, the
Rydex S&P MidCap 400 Pure Growth ETF tracks the S&P MidCap 400/Citigroup Pure
Growth Index, the Rydex S&P SmallCap 600 Pure Value ETF tracks the S&P SmallCap
600/Citigroup Pure Value Index, the Rydex S&P SmallCap 600 Pure Growth ETF
tracks the S&P SmallCap 600/Citigroup Pure Growth 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,
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



NOTES TO FINANCIAL STATEMENTS (continued)

                                       77                 SEMI-ANNUAL REPORT

estimates and assumptions that affect the reported amounts of assets,
liabilities and disclosures at the date of the financial statements and
accompanying notes. 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, at the average of readily
available closing bid and asked prices on such exchange. 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.

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 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. 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 adviser (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, 2006, 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. These differences are primarily due to differing
treatments for in-kind redemptions, income reclassifications from real estate
investment trusts, futures and options, losses deferred due to wash sales and
excise tax regulations.

For the six months ended April 30, 2006, 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, 2006 are disclosed in the Funds
Statement of Operations.

In order to present paid-in-capital, undistributed net investment income and
accumulated net realized losses on investments on the statement of assets and
liabilities that more closely represent their tax character, certain adjustments
have been made to paid-in-capital, undistributed net investment income and
accumulated net realized losses on investments. For the six months ended April
30, 2006, the adjustments for the Funds were as follows:

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 is a
non-diversified fund, subjecting it 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 relevant index. For these services, the Advisor receives
an advisory fee at the annual rate shown below of the average daily net assets
of the Funds.

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 in separate accounts cash, securities and
other assets

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

                                       80

of the Trust and the Funds, 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 Advisor pays all expenses of the Funds, including the cost of transfer
agency, custody, fund administration, legal, audit and other services except
interest, taxes, brokerage commissions, and other expenses connected with the
execution of portfolio transactions, any future distribution fees or expenses
and extraordinary expenses.

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, 2006, 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, shown
below. 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 net asset value per unit of the Fund
on the transaction date.

                               RYDEX INVESTMENTS
         BOARD REVIEW AND APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

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

Consistent with these responsibilities, the Rydex ETF Trust Board of Trustees
(the "Board") calls and holds one meeting each year that is dedicated to
considering whether to renew the investment advisory agreement (the "Advisory
Agreement") between the Trust and PADCO Advisors, Inc., which does business
under the name Rydex Investments ("Rydex Investments") with respect to existing
funds in the Trust, including the funds discussed in this Annual Report (each a
"Fund" and collectively, the "Funds"), and to reviewing certain other agreements
pursuant to which Rydex

                                       83                 SEMI-ANNUAL REPORT

Investments provides investment advisory services to certain other registered
investment companies. In preparation for the meeting, the Board requests and
reviews a wide variety of materials provided by Rydex Investments, including
information about Rydex Investments' affiliates, personnel and operations. The
Board also receives data provided by third parties. This information is in
addition to the detailed information about the Funds that the Board reviews
during the course of each year, including information that relates to Fund
operations and performance. The Board also receives a memorandum from Fund
counsel regarding the responsibilities of the Board for the approval of
investment advisory agreements. In addition, the Independent Trustees receive
advice from independent counsel to the Independent Trustees, meet in executive
session outside the presence of fund management, if necessary, and participate
in question and answer sessions with representatives of Rydex Investments.

At a meeting held on August 28 and 29, 2005, the Board approved the selection of
Rydex Investments and the continuance of the Advisory Agreement for an
additional one-year period, based on its review of qualitative and quantitative
information provided by Rydex Investments. The Board's approval of the Advisory
Agreement was based on consideration and evaluation of a variety of specific
factors discussed at that meeting and at prior meetings, including:

NATURE, EXTENT AND QUALITY OF SERVICES PROVIDED BY RYDEX INVESTMENTS

The Board reviewed the scope of services to be provided by Rydex Investments
under the Advisory Agreement and noted that there would be no significant
differences between the scope of services required to be provided by Rydex
Investments for the past year and the scope of services required to be provided
by Rydex Investments for the upcoming year. In reviewing the scope of services
provided to the Funds by Rydex Investments, the Board reviewed and discussed
Rydex Investments' investment experience, noting that Rydex Investments and its
affiliates have committed significant resources over time to the support of the
Funds. The Board also considered Rydex Investments' compliance program and its
compliance record with respect to the Funds. In that regard, the Board noted
that Rydex Investments provides information regarding the portfolio management
and compliance to the Board on a periodic basis in connection with regularly
scheduled meetings of the Board. In addition to the above considerations, the
Board reviewed and considered Rydex Investments' investment processes and
strategies, and matters related to Rydex Investments' portfolio transaction
policies and procedures. In particular, the Board noted the substantial volume
of portfolio trades and shareholder transaction activity, in general, processed
by Rydex Investments due to the unlimited exchange policy of the majority of the
Funds. The Board further noted that the Funds had met their investment
objectives consistently since their relevant inception dates. Based on this
review, the Board concluded that the nature, extent and quality of services to
be provided by Rydex Investments to the Funds

                                       84

under the Advisory Agreement were appropriate and continued to support the
Board's original selection of Rydex Investments as investment adviser to the
Funds.

FUND EXPENSES AND PERFORMANCE OF THE FUNDS AND RYDEX INVESTMENTS

The Board reviewed statistical information prepared by Rydex Investments
regarding the expense ratio components, including actual advisory fees,
waivers/reimbursements, and gross and net total expenses of each Fund. In
addition, the Board reviewed statistical information prepared by Rydex
Investments relating to the performance of each Fund, as well as each Fund's
ability to successfully track its benchmark over time, and a comparison of each
Fund's performance to funds with similar investment objectives for the same
periods and to appropriate indices/benchmarks, in light of total return, yield
and market trends. Based on this review, the Board concluded that the investment
advisory fees and expense levels and the historical performance of the Funds, as
managed by Rydex Investments, as compared to the investment advisory fees and
expense levels and performance of the peer funds, were satisfactory for the
purposes of approving the continuance of the Advisory Agreement.

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

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

ECONOMIES OF SCALE

In connection with its review of the Funds' profitability analysis, the Board
reviewed information regarding economies of scale or other efficiencies that may
result from increases in the Funds' asset levels. The Board noted that the
Advisory Agreement for

the Funds did not provide for any breakpoints in the investment advisory fee
rates as a result of increases in the asset levels of such Funds. However, the
Board further noted that possible future economies of scale had been taken into
consideration by fixing the investment advisory fee at rates at the lower end of
the marketplace, effectively giving Fund shareholders, from inception, the
benefits of the lower average fee shareholders would have received from a fee
structure with declining breakpoints where the initial fee was higher. The Board
also reviewed Rydex Investments' historic profitability as investment adviser to
the Funds and determined that reductions in fee rates or additions of
breakpoints were not warranted at this juncture. Based on this review, the
Board, recognizing its responsibility to consider this issue at least annually,
concluded that there are limited economies of scale to share with the Funds'
shareholders.

OTHER BENEFITS TO RYDEX INVESTMENTS AND/OR ITS AFFILIATES

The Board noted that Rydex Investments reports its use of soft dollars to the
Board on a quarterly basis, as well as any portfolio transactions on behalf of
the Funds placed through an affiliate of the Funds or Rydex Investments pursuant
to Rule 17e-1 under the 1940 Act. The Board concluded that any such ancillary
benefits would not be disadvantageous to the Funds' shareholders.

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

ITEM 2. CODE OF ETHICS.

The Board of Trustees of the Trust has adopted a Combined Code of Ethics (the
"Code") pursuant to Rule 17j-1 under the 1940 Act. The Advisor and Distributor
are also covered by the Code. The Code applies to the personal investing
activities of trustees, directors, officers, and certain employees ("access
persons"). Rule 17j-1 and the Code are designed to prevent unlawful practices in
connection with the purchase or sale of securities by access persons. Under the
Code, access persons are permitted to engage in personal securities
transactions, but are required to report their personal securities transactions
for monitoring purposes. In addition, certain access persons are required to
obtain approval before investing in initial public offerings or private
placements. No substantive amendments were approved or waivers were granted to
the Code during the period covered by this report. The Code is filed as an
exhibit to this Form N-CSR.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

While the members of the audit committee have many years of experience in
business and finance, including working with fund financial statements and
auditors, they do not feel that the background and experience of any single
member would meet the qualifications necessary to be a "financial expert" as
that term is defined by the Securities and Exchange Commission. Nonetheless, the
committee has determined that, together, its collective financial experience and
expertise makes an individual financial expert unnecessary at this time.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a)-(d)  The aggregate Audit Fees billed by PricewaterhouseCoopers LLP ("PWC"),
the Trust's principal accountant, for the audit of the annual financial
statements in connection with statutory and regulatory filings for the fiscal
years ended October 31, 2005 and October 31, 2004 were $32,400 and $21,200,
respectively. The aggregate Tax Fees billed by PWC for professional services
rendered for tax compliance, tax advice, and tax planning, including preparation
of tax returns and distribution assistance, for the fiscal years ended October
31, 2005 and December 31, 2004 were $30,000 and $14,840, respectively.

(e)      The audit committee has adopted a policy whereby audit and non-audit
services performed by the registrant's principal accountant for the registrant,
its investment advisor, and any entity controlling, controlled by, or under
common control with the investment advisor that provides ongoing services to the
registrant require pre-approval in advance at regularly scheduled audit
committee meetings. If such service is required between regularly scheduled
audit committee meetings, the chairman of the audit committee, J. Kenneth
Dalton, is authorized to pre-approve the service with full committee approval at
the next scheduled meeting. There



shall be no waivers of the pre-approval process. No services described in
(b)-(d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of
Regulation S-X.

(f)      Not applicable.

(g)      Not applicable.

(h)      Not applicable.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

The Rydex ETF Trust has a separate designated audit committee, which consists of
the independent trustees. The audit committee members are J. Kenneth Dalton,
John O. Demaret, Patrick T. McCarville, Corey A. Colehour and Roger Somers.

ITEM 6. SCHEDULE OF INVESTMENTS

Schedule of Investments is included as part of the report to shareholders filed
under Item 1 of this form.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

Not applicable.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not applicable.

ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT
COMPANY AND AFFILIATED PURCHASERS.

Not applicable.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

Not applicable.

ITEM 11. CONTROLS AND PROCEDURES.

(a)      Based on their evaluation on January 10, 2006, 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
Advisors ("RGA"), the investment advisor and manager of the Trust, and State
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
registrant's internal control over financial reporting.


ITEM 12. EXHIBITS.

(a)(1)   The registrant's code of ethics pursuant to Item 2 of Form N-CSR is
attached.

(a)(2)   Separate certifications by the President (principal executive officer)
and Treasurer (principal financial officer) of the registrant as required by
Rule 30a-2(a) under the Act (17 CFR 270.30a-2(a)) are attached.

(b)      A certification by the registrant's President (principal executive
officer) and Treasurer (principal financial officer) as required by Rule
30a-2(b) under the Act (17 CFR 270.30a-2(b)) is attached.
