                       LANDSCAPE AT AUVERS AFTER THE RAIN

                     BY VINCENT VAN GOGH (1853-1890, DUTCH)

        VAN GOGH SPENT ONLY THREE MONTHS IN AUVERS-SUR-OISE, A SMALL VIL-

         LAGE NORTH OF PARIS, WHERE HE PRODUCED THE LAST OF HIS BELOVED

         PAINTINGS. THIS LANDSCAPE, AMONG HIS TRIBUTES TO THE HEALTH AND

        RESTORATIVE FORCES OF THE FRENCH COUNTRYSIDE, IS A FITTING EMBLEM

            FOR THE GROWTH POTENTIAL OF AIM'S NEWEST HIGH-YIELD FUND.

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


AIM High Yield Fund II is for shareholders who seek a high level of current
income. The fund invests in a portfolio consisting primarily of high-yielding,
lower-rated corporate bonds.

ABOUT FUND PERFORMANCE AND PORTFOLIO DATA THROUGHOUT THIS REPORT:

o   AIM High Yield Fund II's performance figures are historical, and they
    reflect changes in net asset value and the reinvestment of distributions.
o   When sales charges are included in performance figures, Class A share
    performance reflects the maximum 4.75% sales charge, and Class B and Class C
    share performance reflects the applicable contingent deferred sales charge
    (CDSC) for the period involved. The CDSC on Class B shares declines from 5%
    beginning at the time of purchase to 0% at the beginning of the seventh
    year. The CDSC on Class C shares is 1% for the first year after purchase.
    The performance of the fund's Class B and Class C shares will differ from
    that of its Class A shares due to different sales-charge structure and
    expenses.
o   Had the advisors not absorbed fund exenses, performance figures would have
    been lower.
o   The fund's average annual total returns, including sales charges, for the
    periods ended 12/31/99 (the most recent calendar quarter-end) are as
    follows. For Class A shares, one year, 14.14%; inception (9/30/98), 18.65%.
    For Class B shares, one year, 13.90%; inception (11/20/98), 14.07%. For
    Class C shares, one year, 17.69%; inception (11/20/98), 17.52%
o   The 30-day yield is calculated using a formula prescribed by the SEC. The
    formula is based on the portfolio's potential earnings from dividends,
    interest, yield-to-maturity or yield-to-call of the bonds in the portfolio,
    net of all expenses and annualized.
o   The fund invests primarily in higher-yielding, lower-rated corporate bonds,
    commonly known as "junk bonds." These bonds have a greater risk of price
    fluctuation and loss of principal and income than U.S. government
    securities, such as U.S. Treasury bonds and bills, which offer a government
    guarantee as to the repayment of principal and interest if held to maturity.
o   The fund's investment return and principal value will fluctuate, so an
    investor's shares, when redeemed, may be worth more or less than their
    original cost.

ABOUT INDEXES AND OTHER PERFORMANCE BENCHMARKS CITED IN THIS REPORT:

o   The unmanaged Lehman High Yield Bond Index, generally considered
    representative of high-yield debt securities, is compiled by Lehman
    Brothers, a well-known global investment bank.
o   The unmanaged Lipper High Current Yield Fund Index represents an average of
    the performance of the 30 largest high-yield funds charted by Lipper, Inc.,
    an independent mutual fund performance monitor.
o   An investment cannot be made directly in an index. Unless otherwise
    indicated, index results include reinvested dividends, and they do not
    reflect sales charges.

   AN INVESTMENT IN THE FUND IS NOT A DEPOSIT OF A BANK AND IS NOT INSURED OR
      GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER
      GOVERNMENT AGENCY. THERE IS A RISK THAT YOU COULD LOSE SOME OR ALL OF
                                   YOUR MONEY.

   This report may be distributed only to current shareholders or to persons

                   Dear Fellow Shareholders:

                   Many investors have been disappointed in their fixed-income
     [PHOTO OF     investments' performance during the six months covered by
    Charles T.     this report. The Federal Reserve Board (the Fed) raised
      Bauer,       interest rates twice during the reporting period and again
   Chairman of     shortly after the period closed, putting downward pressure on
   the Board of    the prices of fixed-income investments. Nevertheless, there
     THE FUND      is cause for celebration of 1999 bond investments--and hope
   APPEAR HERE]    for 2000. For investors who stayed the course with their
                   fixed-income funds last year, their investment dollars were
                   used to purchase bonds at significant discounts, as
                   fixed-income securities of all types were true bargains. In
                   addition, yields on some fixed-income investments rose
                   significantly during the reporting period.

                   LOOKING AHEAD
                   most market watchers anticipate that bond market conditions
will remain difficult through the first half of 2000, as the Fed may raise
interest rates again to try to steer the economy to a soft landing: economic
growth diminished enough to thwart inflation, but without recession. But
analysts also remind us that, historically, fixed-income markets have rebounded
the year following a down year such as 1999. If so, 2000 may be a year of
recovery for fixed-income investing.
    In addition, many analysts believe bond markets have in the past fared well
on the down side of a Fed tightening cycle. Assuming economic growth and low
inflation continue on their current path, there's every reason to be optimistic
about fixed-income funds.
    The changeable nature of the markets reinforces our confidence in the wisdom
of investing through a financial advisor. In addition to helping you select
investments appropriate to your time horizon and risk tolerance, a financial
advisor can keep you informed about how shifting market conditions affect you
and your portfolio--and help assure that when you do alter your investments,
there's a logical reason for doing so. AIM believes every investor should be
guided by a financial professional.

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW



AIM HIGH YIELD FUND II THRIVES IN DIFFICULT
BOND ENVIRONMENT


HOW DID AIM HIGH YIELD FUND II PERFORM DURING THE REPORTING PERIOD?
Fixed-income markets continued to be plagued by a stubbornly strong U.S. economy
and higher interest rates. Given this difficult market environment, AIM High
Yield Fund II posted a 5.31% return for Class A shares, a 4.92% return for Class
B shares and a 4.93% return for Class C shares for the six months ended January
31, 2000. These returns are computed at net asset value (that is, without the
effect of sales charges). The fund outperformed the Lehman High Yield Bond
Index, which returned 0.64%, and the Lipper High Current Yield Fund Index, which
gained 0.36% during the same period.
    Despite 1999's poor market environment, the fund continued to provide
extremely attractive current income. As of January 31, 2000, the fund's 30-day
SEC yield was 10.91%, 10.70% and 10.70% for Class A, Class B and Class C shares,
respectively. By comparison, the yield on the 30-year U.S. Treasury bond was
6.49%.

WHAT WERE THE MAJOR TRENDS IN BOND MARKETS DURING 1999?
Throughout 1999, downward pressure on bond prices resulted from the U.S.
economy's continued strong growth, low unemployment, rising commodity prices,
improving global economies, rising long-term interest rates and heightened
inflation fears. These factors contributed to a market environment in which
investors favored stocks over bonds. Bond investors are particularly attuned to
any hint of inflation, since it erodes the purchasing power of future interest
and principal payments. For these reasons, bonds in general had a very difficult
year.

HOW DID HIGH-YIELD BONDS FARE IN THIS DIFFICULT MARKET ENVIRONMENT?
High-yield bonds were able to withstand some of the pressure of rising interest
rates and ended up being one of the better-performing fixed-income sectors in
1999. During the year, issuers flooded the market with high-yield bonds--many of
them to ensure they would have adequate capital should Y2K-related problems
materialize. This massive supply was met with lackluster demand from buyers,
some of whom may have had Y2K-related concerns about buying high-yield bonds in
such an atmosphere of uncertainty. As Y2K approached, liquidity in the
high-yield market simply dried up, pushing high-yield bond prices downward.
    High-yield bond funds also suffered from negative fund flows. In contrast to
the past several years, when high-yield bond funds enjoyed record cash inflows,
lower bond prices and greater market volatility during much of the six months
covered by this report eroded investor interest in this sector. Many investors
exited the fixed-income markets and entered the equities markets.
    Tax-loss selling and Y2K pressures in December caused more disappointments.
These actions pushed the average yield of high-yield bonds up to almost 12% at
the end of 1999-approximately 120 basis points over historical standards.(A
basis point is one one-hundredth of a percentage point.)

GIVEN CURRENT MARKET CONDITIONS, HOW DID YOU MANAGE THE FUND'S CREDIT QUALITY?
While yield spreads have come down from their 1998 levels, they still remain
high on a historical basis. As a result, we have found opportunities for higher
yields in the lower-quality sectors of the high-yield market. Lower-quality
sectors of the high-yield bond market generally offer higher yields to
compensate investors for taking on more risks. On January 31, CCC and non-rated
bonds accounted for approximately 30% of the fund's net assets, compared to less
than 7% six months ago.

    Overall, the fund has an average credit quality of B, as rated by Standard &
Poor's, a widely known credit-rating agency.

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW


WHAT CHANGES DID YOU MAKE TO THE FUND'S PORTFOLIO?
The fund's exposure to issuers in the telecommunications and telephone
industries, which represented more than 37% of total net assets on January 31,
helped fuel fund performance. We continue to believe that these industries
represent attractive value, and the fund's performance has greatly benefited
from continued consolidation in these industries.
    During the reporting period, we increased our allocation in foreign
developed countries to approximately 10%. Bonds issued by foreign
telecommunications companies accounted for most of the increase. The
underpinnings of a sustained global expansion make the telecommunications
high-yield sector attractive.

DID THE EQUITIES COMPONENT OF THE FUND CONTRIBUTE POSITIVELY TO ITS SUCCESS
DURING THE REPORTING PERIOD?
Very much so. Fund managers may invest up to 15% of the fund's assets in
equities (stocks of companies in which we hold high-yield debt) if those stocks
represent compelling value. This policy allows fund managers to leverage their
research capabilities; having researched a company from a debt perspective, it
takes just a little more effort to research its stock. The fund benefits because
its equity component may perform well even when bonds may be underperforming,
thereby increasing the fund's total return. Because equities do not provide
income, managers try to avoid reducing the fund's yield substantially.
   During 1999, fund managers used the strength of equity markets as an
opportunity to increase their holdings of stock of companies in which we held
debt. Fund managers concentrated their equity ownership in rapidly growing
telephone and telecommunications companies, which enjoyed tremendous price
appreciation during the reporting period.

WHAT IS YOUR OUTLOOK FOR THE REMAINDER OF 2000?
The prospect of higher interest rates and further defaults will keep the level
of uncertainty and volatility high in the high-yield sector. As a result, a
recovery in the high-yield market may not occur until the second half of 2000.
Although the past year and a half has been difficult for the high-yield market,
we believe the worst may be behind us. In these uncertain market conditions, we
will continue to take selective advantage of attractively valued high-yield
credits with the perspective that over the long term, these credits should
provide attractive income and total-return opportunities for our investors.
    We also believe that the current high-yield environment represents an
excellent opportunity for investors. When compared to the long-term yield
average, high-yield bonds seem cheap relative to other alternatives in the
fixed-income universe.

fund will continue to hold any particular security.

NOTES TO FINANCIAL STATEMENTS

January 31, 2000
(unaudited)
NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM High Yield Fund II (the "Fund") is a series portfolio of AIM Investment
Securities Funds (the "Trust"). The Trust is a Delaware business trust
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end series management company consisting of two separate
series portfolios. The Fund currently offers three different classes of shares:
Class A shares, Class B shares and Class C shares. Class A shares are sold with
a front-end sales charge. Class B and Class C shares are sold with a contingent
deferred sales charge. Matters affecting each portfolio or class are voted on
exclusively by the shareholders of such portfolio or class. The assets,
liabilities and operations of each portfolio are accounted for separately.
Information presented in these financial statements pertains only to the Fund.
The Fund's investment objective is to achieve a high level of current income by
investing primarily in publicly traded, non-investment grade debt securities.
The Fund will also consider the possibility of capital growth when it purchases
and sells securities. Debt securities of less than investment grade are
considered "high-risk" securities (commonly referred to as junk bonds). These
bonds may involve special risks in addition to the risks associated with higher
rated debt securities. High yield bonds may be more susceptible to real or
perceived adverse economic conditions than higher grade bonds. Also, the
secondary market in which high yield bonds are traded may be less liquid than
the market for higher grade bonds.
  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of 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 those estimates. The
following is a summary of the significant accounting policies followed by the
Fund in the preparation of its financial statements.

A.  Security Valuations -- A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price of the customary
    trading session on the exchange where the security is principally traded, or
    lacking any sales on a particular day, the security is valued at the closing
    bid price on that day. Each security reported on the NASDAQ National Market
    System is valued at last sale price of the customary trading session on the
    valuation date or absent a last sales price, at the closing bid price. Dept
    obligations (including convertible bonds) are valued on the basis of prices
    provided by an independent pricing service. Prices provided by the pricing
    service may be determined without exclusive reliance on quoted prices, and
    may reflect appropriate factors such as yield, quality, type of issue,
    coupon rate and maturity date. Securities for which market prices are not
    provided by any of the above methods are valued based upon quotes furnished
    by independent sources and are valued at the last bid price in the case of
    equity securities and in the case of debt obligations, the mean between the
    last bid and asking prices. Securities for which market quotations are not
    readily available or are questionable are valued at fair value as determined
    in good faith by or under the supervision of the Trust's officers in a
    manner specifically authorized by the Board of Trustees. Short-term
    obligations having 60 days or less to maturity are valued at amortized cost
    which approximates market value. For purposes of determining net asset value
    per share, futures and option contracts generally will be valued 15 minutes
    after the close of trading of the customary trading session of the New York
    Stock Exchange ("NYSE").

    Generally, trading in foreign securities is substantially completed each day
    at various times prior to the close of the NYSE. The values of such
    securities used in computing the net asset value of the Fund's shares are
    determined as of such times. Foreign currency exchange rates are also
    generally determined prior to the close of the NYSE. Occasionally, events
    affecting the values of such securities and such exchange rates may occur
    between the times at which they are determined and the close of the NYSE
    which would not be reflected in the computation of the Fund's net asset
    value. If events materially affecting the value of such securities occur
    during such period, then these securities will be valued at their fair value
    as determined in good faith by or under the supervision of the Board of
    Trustees.

B.  Securities Transactions and Investment Income -- Securities transactions are
    accounted for on a trade date basis. Realized gains or losses on sales are
    computed on the basis of specific identification of the securities sold.
    Interest income, adjusted for amortization of discounts on investments, is
    recorded as earned from settlement date and is recorded on the accrual
    basis. It is the policy of the Fund not to amortize bond premiums for
    financial reporting purposes.

C.  Distributions -- It is the policy of the Fund to declare daily dividends
    from net investment income. Such distributions are paid monthly.
    Distributions from net realized capital gains, if any, are generally paid
    annually and recorded on ex-dividend date. The Fund may elect to use a
    portion of the proceeds of fund share redemptions as distributions for
    Federal income tax purposes.

D.  Federal Income Taxes -- The Fund intends to comply with the requirements of
    the Internal Revenue Code necessary to qualify as a regulated investment
    company and, as such, will not be subject to federal income taxes on
    otherwise taxable income (including net realized capital gains) which is
    distributed to shareholders. Therefore, no provision for federal income
    taxes is recorded in the financial statements.

E.  Expenses -- Distribution expenses and transfer agency expenses directly
    attributable to a class of shares are charged to

                                        9
<PAGE>   12

   that class' operations. All other expenses which are attributable to more
   than one class are allocated among the classes.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment advisory
agreement, the Fund pays an advisory fee to AIM at an annual rate of 0.625% on
the first $500 million of the Fund's average daily net assets, plus 0.55% on the
next $500 million of Fund's average daily net assets, plus 0.50% on the Fund's
average daily net assets in excess of $1 billion. During the six months ended
January 31, 2000, AIM waived fees of $123,843.
  The Fund, pursuant to a master administrative services agreement with AIM, has
agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. For the six months ended January 31, 2000, AIM
was paid $21,027 for such services.
  The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agency and
shareholder services to the Fund. For the six months ended January 31, 2000, AFS
was paid $25,509 for such services.
  The Trust has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares of the Fund. The Trust has adopted plans
pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund's Class A
shares, Class B shares and Class C shares (collectively the "Plans"). The Fund,
pursuant to the Plans, pays AIM Distributors compensation at the annual rate of
0.25% of the Fund's average daily net assets of Class A shares and 1.00% of the
average daily net assets of Class B and C shares. Of these amounts, the Fund may
pay a service fee of 0.25% of the average daily net assets of the Class A, Class
B or Class C shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
the appropriate class of shares of the Fund. Any amounts not paid as a service
fee under the Plans would constitute an asset-based sales charge. The Plans also
impose a cap on the total sales charges, including asset-based sales charges
that may be paid by the respective classes. For the six months ended January 31,
2000, the Class A, Class B and Class C shares paid AIM Distributors $47,913,
$162,591 and $24,312, respectively, as compensation under the Plans.
  AIM Distributors received commissions of $73,964 from sales of the Class A
shares of the Fund during the six months ended January 31, 2000. Such
commissions are not an expense of the Fund. They are deducted from, and are not
included in, the proceeds from sales of Class A shares. During the six months
ended January 31, 2000, AIM Distributors received $7,451 in contingent deferred
sales charges imposed on redemptions of Fund shares.
  Certain officers and trustees of the Trust are officers and directors of AIM,
AFS and AIM Distributors.
  During the six months ended January 31, 2000, the Fund paid legal fees of
$1,257 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel
to the Trustees. A member of that firm is a trustee of the Trust.

NOTE 3-INDIRECT EXPENSES

During the six months ended January 31, 2000, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $432 and $9,866, respectively, under expense offset arrangements. The
effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $10,298 during the six months ended January 31, 2000.

NOTE 4-TRUSTEES' FEES

Trustees' fees represent remuneration paid to trustees who are not an
"interested person" of AIM. The Trust invests trustees' fees, if so elected by a
trustee, in mutual fund shares in accordance with a deferred compensation plan.

NOTE 5-BANK BORROWINGS
