DEAR SHAREHOLDER:

    The second and third quarters of 1999 saw dramatic shifts in market
sentiments as investors rotated through several different sectors. This was the
result of new trends, which established themselves in the world's economies. As
the U.S. economy continued to thrive, emerging economies in Asia and other
foreign countries returned to stability. A stronger world economy and OPEC
production cuts sent crude oil prices from approximately $11 back up to above
$24 a barrel. Gold, copper, and other non-agricultural commodity prices rose.
Inflation stayed in check, but the dollar sank against the yen and the Fed
raised interest rates twice.

MARKET ENVIRONMENT

    In early spring economists raised their growth forecasts and economic data
suggested that manufacturing activity was booming. Fearing higher rates,
investors started to rotate out of the growth sectors and into metals,
chemicals, paper, and other classic cyclical stocks that make up the BASIC
MATERIALS sector. At the same time, oil prices began to rise sharply as OPEC
held to its recently established quotas, causing ENERGY and ENERGY SERVICE
stocks to rally. Airline stocks, which are a large part of the TRANSPORTATION
sector, do not fare well when oil prices increase. Since OPEC moved to tighten
production, jet fuel prices have soared more than 80% and airline shares have
been selling off since April. In HEALTH CARE, drug company stocks that had been
market favorites began to falter in early April as investors rotated into
BIOTECHNOLOGY shares. Investors believed double-digit growth rates were more
likely in the biotech sector than in the large pharmaceutical concerns.

    By early summer, Federal Reserve Chairman Alan Greenspan expressed concerns
that potential labor shortages and the runaway U.S. stock market may lead to
rising inflation and threaten the economy, now in its ninth year of growth. At
their June meeting, Federal Reserve policy makers then raised the federal funds
rate a quarter of a point to five percent, but they chose to adopt a policy
toward a neutral bias. Convinced that interest rates would not rise in the near
term, investors dumped cyclical stocks and went back into growth stocks
dominated by TECHNOLOGY names.
<PAGE>
    The TECHNOLOGY sector continued to outperform the market as it has almost
every year this decade. A relatively small number of giant technology firms led
by Microsoft, Intel, IBM, Cisco and Lucent accounted for approximately half of
the sector's return. The explosion of Internet traffic over phone lines has been
a major factor in the growth of the TELECOMMUNICATIONS sector. The proliferation
of the Internet is also a positive factor for the ELECTRONICS sector due to
rising demand for semiconductors, which are also increasingly used in electronic
equipment, cellular phones and automobiles. Interest rate-sensitive sectors
began to decline after the first rate hike. Along with interest rate fears, the
BANKING sector disappointed investors with a lack of merger activity. FINANCIAL
SERVICE stocks respond negatively to higher interest rates because of the impact
that higher rates have on economic growth and the demand for credit. The RETAIL
sector has always had an inverse relationship with interest rates; although
consumer spending has remained strong, there is concern that market share is not
expanding as rapidly among the broadline chains.

    Consumer non-durable stocks have continued to lag behind the broad markets
because of high penetration in developed domestic markets. Companies such as
Colgate-Palmolive and Proctor & Gamble are counting on expansion overseas to
drive long-term growth.

    Ultimately, the winners in the dramatic shifts of the second and third
quarters included energy stocks and growth sectors such as technology,
telecommunications, and biotechnology, while interest rate-sensitive sectors did
not fare as well.

Sincerely,

[/S/ ALBERT P. VIRAGH, JR.]

1.  SIGNIFICANT ACCOUNTING POLICIES

The Rydex Series Trust (the "Trust") is registered with the Securities and
Exchange Commission under the Investment Company Act of 1940 (the "1940 Act") as
a non-diversified, open-ended investment company, and is authorized to issue an
unlimited number of shares. The Trust offers two separate classes of shares,
Investor Class Shares and Advisor Class Shares. Sales of shares of each Class
are made without a sales charge at the net asset value per share. Currently, the
Trust consists of twenty-two separate series: six benchmark funds; one money
market fund, and fifteen sector funds. This report covers the fifteen sector
funds (the "Sector Funds"), while the Benchmark Funds and Money Market Fund are
contained in a separate report. The following significant accounting policies
are in conformity with generally accepted accounting principles and are
consistently followed by the Trust.

During 1997, the Trust changed its fiscal year end from June 30 to March 31.
Accordingly, statements for the period March 31, 1997, reflect nine months of
activity.

A. Securities listed on an exchange are valued at the last quoted sales price as
of 4:00 P.M. on the valuation date. Securities not traded on an exchange are
valued at their last sales price. Listed options held by the Trust are valued at
their last bid price. Over-the-counter options held by the Trust are valued
using the average bid price obtained from one or more security dealers. The
value of futures contracts purchased and sold by the Trust are accounted for
using the unrealized gain or loss on the contracts that is determined by marking
the contracts to their current realized settlement prices. Short-term securities
are valued at amortized cost, which approximates market. Securities and assets
for which market quotations are not readily available are valued at fair value
as determined in good faith by or under direction of the Board of Trustees or by
the Advisor using methods established or ratified by the Board of Trustees.

B. Securities transactions are recorded on the day the trade is executed for the
purpose of preparing semi-annual and annual financial statements. Realized gains
and losses from securities transactions are recorded on the identified cost
basis. Dividend income is recorded on the ex-dividend date, net of applicable
taxes withheld by foreign countries, and subsequently adjusted to reflect actual
holdings of the record date. Interest income is accrued on a daily basis.

C. The Trust intends to comply with the provisions of the Internal Revenue Code
applicable to regulated investment companies and will distribute all net
investment income to its shareholders. Therefore, no Federal income tax
provision is required.

D. Costs incurred in connection with the organization and registration of the
Sector Funds have been expensed as incurred.

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

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

E. Interest and dividend income, most expenses, all realized gains and losses,
and all unrealized gains and losses are allocated to the classes based upon the
value of the outstanding shares in each Class. Certain costs are charged
directly to specific classes, for example, distribution fees relating to the
Advisor Classes.

F. Distributions to shareholders are recorded on the ex-dividend date.
Distributions are determined on a tax basis and may differ from net investment
income and realized capital gains for financial reporting purposes.

G. The Precious Metals Fund seeks capital appreciation. It buys primarily equity
securities and may purchase call options on the Philadelphia Stock Exchange
Gold/Silver Index ("XAU Index"). In additon, the Precious Metals Fund can write
options to further meet its investment objectives. The risks inherent in the use
of options include 1) adverse changes in the value of such instruments; 2)
imperfect correlation between the price of options and movements in the price of
the underlying securities or index; and 3) the possible absence of a liquid
secondary market for any particular instrument at any time.

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

2.  REPURCHASE AGREEMENTS

The Trust, which includes twenty-two separate series, transfers uninvested cash
balances into a single joint account, the daily aggregate balance of which is
invested in one or more repurchase agreements collateralized by U. S. Treasury
obligations. As of September 30, 1999, the repurchase agreements with Fuji
Securities, Inc., Paine Webber, Inc., Lehman Brothers, and Prudential
Securities, Inc., in the joint account and the collateral therefore was as
follows:
