Past performance is no guarantee of future  performance.  The performance of the
other  classes  will vary from the  performance  of the class  shown  because of
differences  in  sales  charges  and  fees  paid by  shareholders  investing  in
different classes.

Dear Shareholder,

     We are  pleased to present you with the annual  report for the  PaineWebber
Tactical Allocation Fund (the "Fund") for the fiscal year ended August 31, 1999.


MARKET REVIEW
- --------------------------------------------------------------------------------

   For most of 1998 and the first quarter of 1999 the market was very narrow,
focused primarily on large-capitalization growth companies. This was a highly
unusual situation and we expected conditions to return to normal--i.e., near
parity between growth and value styles. The market did briefly turn around in
the second quarter, but only the most undervalued of the value stocks benefited
before investors got concerned about the surge in commodity prices, and
narrowness returned. However, for the 12 months ended August 31, 1999, the S&P
500 Index gained 39.81%.

   Despite gains in the broad market, individual stock performance varied
widely. About two thirds of the stocks traded on the New York Stock Exchange
have actually posted losses year to date. The market weakened at the end of the
Fund's fiscal year, as investors became concerned about the possibility of the
Federal Reserve again raising short-term interest rates. Technology and consumer
cyclicals were the strongest sectors; the weakest sectors included healthcare,
utilities and capital goods.


PORTFOLIO REVIEW
- --------------------------------------------------------------------------------

   Management employs the Tactical Allocation Model (the "Model") to determine
the Fund's asset mix between an equity portion designed to track the performance
of the S&P 500 Index and a fixed-income portion consisting of either bonds
(five-year U.S. Treasury notes) or cash (30-day U.S. Treasury bills). The Model
is a systematic, quantitative approach to calculating expected risk premiums --
the anticipated return advantage -- of stocks and bonds relative to cash. The
decision process compares the expected return of the stock market and of bonds
with the "risk-free" asset (the one-year Treasury bill) to determine the equity
risk premium (ERP) and bond risk premium (BRP) and, as a result, the portfolio's
weighting, if any, in stocks and bonds.

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

   Historically, the ERP has averaged about five percentage points per year. If
the ERP is 5.5% or greater, the Fund is fully invested in stocks. If the ERP
falls below the 5.5% hurdle rate, it indicates that the expected return of the
stock market does not fully compensate investors for the expected risk of owning
stocks. Therefore, some or all of the Fund's assets would be shifted to bonds or
cash, depending on the bond risk premium. For every 0.5% that the ERP drops
below 5.5%, the Model would signal that another 25% of the Fund's assets must be
shifted out of stocks.

   Historically, the BRP has averaged 0.5%. If this spread is 0.5% or greater,
the fixed-income portion, if any, is invested in bonds; if the spread is less
than 0.5%, any fixed-income portion is allocated to cash (the 30-day Treasury
bill).

   The Fund's Model attempts to outperform the S&P 500 Index over the long term
with less volatility by shifting assets between stocks and bonds or cash. Of
course, as with all investment disciplines, there is no guarantee the Model will
accurately anticipate significant shifts in the markets and correctly determine
when to move into or out of stocks, bonds or cash.

OUTLOOK
- --------------------------------------------------------------------------------

   The economy continues to have positive momentum. Within the data set that we
use in the Tactical Allocation discipline we have seen upward revisions of
earnings estimates. Inflation as measured by the Consumer Price Index appears to
be low and stable, running about 2.5% year-to-date versus its 30-year average
rate of 5.5%. Short-term interest rates have not risen to a level that could
choke off continued positive growth. In this environment, the equity risk
premium in the Tactical model remains above the 5.5% hurdle rate that we require
for stocks to be attractive to investors. Thus, the Fund continues to be fully
invested in the equity market.

1  Figures assume reinvestment of all dividends and capital gain distributions
   at net asset value on the payable dates and do not include sales charges;
   results for each class would be lower if sales charges were included. Total
   investment return for periods of less than one year has not been annualized.

   Note: The Fund offers Class Y shares to a limited group of eligible
   investors, including participants in certain investment programs that are
   sponsored by PaineWebber and may invest in PaineWebber mutual funds. For the
   year ended August 31, 1999 and since inception, May 10, 1993 through August
   31, 1999, Class Y shares have a total return of 39.03% and 221.13%,
   respectively. Class Y shares do not have initial or contingent deferred sales
   charges or ongoing distribution and service fees.

   The data above represents past performance of the Fund's shares, which is no
   guarantee of future results. The principal value of an investment in the Fund
   will fluctuate, so that an investor's shares, when redeemed, may be worth
   more or less than their original cost.

NOTES TO FINANCIAL STATEMENTS



ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

    PaineWebber Tactical Allocation Fund (the "Fund") is a series of PaineWebber
Investment Trust (the "Trust") and is registered with the Securities and
Exchange Commission under the Investment Company Act of 1940, as amended, as an
open-end, diversified management investment company.

    Currently, the Fund offers Class A, Class B, Class C and Class Y shares.
Each class represents interests in the same assets of the Fund, and the classes
are identical except for differences in their sales charge structures, ongoing
service and distribution charges and certain transfer agency expenses. In
addition, Class B shares and all corresponding reinvested dividend shares
automatically convert to Class A shares approximately six years after issuance.
All classes of shares have equal voting privileges except that Class A, Class B,
and Class C shares each have exclusive voting rights with respect to their
respective service and/or distribution plans. Class Y shares have no service or
distribution plan.

    The preparation of financial statements in accordance with generally
accepted accounting principles requires Fund management to make estimates and
assumptions that affect the reported amounts and disclosures in the financial
statements. Actual results could differ from those estimates. The following is a
summary of significant accounting policies:

    VALUATION OF INVESTMENTS--The Fund calculates net asset values based on the
current market value for its portfolio's securities. The Fund normally obtains
market values for its securities from independent pricing sources. Independent
pricing sources may use reported last sale prices, current market quotations or
valuations from computerized "matrix" systems that derive values based on
comparable securities. Securities traded in the over-the-counter ("OTC") market
and listed on The Nasdaq Stock Market, Inc. ("Nasdaq") normally are valued at
the last sale price on Nasdaq prior to valuation. Other OTC securities are
valued at the last bid price available prior to valuation. Securities which are
listed on U.S. and foreign stock exchanges normally are valued at the last sale
price on the day the securities are valued or, lacking any sales on such day, at
the last available bid price. In cases where securities are traded on more than
one exchange, the securities are valued on the exchange designated as the
primary market by Mitchell Hutchins Asset Management Inc. ("Mitchell Hutchins"),
a wholly owned asset management subsidiary of PaineWebber Incorporated
("PaineWebber") and investment adviser and administrator of the Fund. If a
market value is not available from an independent pricing source for a
particular security, that security is valued at fair value as determined in good
faith by or under the direction of the Trust's board of trustees (the "board").
The amortized cost method of valuation, which approximates market value,
generally is used to value short-term debt-instruments with sixty days or less
remaining to maturity, unless the Trust's board determines that this does not
represent fair value.

    REPURCHASE AGREEMENTS--The Fund's custodian takes possession of the
collateral pledged for investments in repurchase agreements. The underlying
collateral is valued daily on a mark-to-market basis to ensure that the value,
including accrued interest, is at least equal to the repurchase price. In the
event of default of the obligation to repurchase, the Fund has the right to
liquidate the collateral and apply the proceeds in satisfaction of the
obligation. Under certain circumstances, in the event of default or bankruptcy
by the other party to the agreement, realization and/or retention of the
collateral may be subject to legal proceedings. The Fund occasionally
participates in joint repurchase agreement transactions with other funds managed
by Mitchell Hutchins.

    INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--Investment transactions are
recorded on the trade date. Realized gains and losses from investment
transactions are calculated using the identified cost method. Interest income is
recorded on an accrual basis. Dividend income is recorded on the ex-dividend
date. Discounts are accreted and premiums are amortized as adjustments to
interest income and the identified cost of investments.


                                                                              17

NOTES TO FINANCIAL STATEMENTS



    Income, expenses (excluding class-specific expenses) and realized/unrealized
gains/losses are allocated proportionately to each class of shares based upon
the relative net asset value of outstanding shares (or the value of
dividend-eligible shares, as appropriate) of each class at the beginning of the
day (after adjusting for current capital share activity of the respective
classes). Class-specific expenses are charged directly to the applicable class
of shares.

    DIVIDENDS AND DISTRIBUTIONS--Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends and distributions are
determined in accordance with federal income tax regulations, which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification.

INVESTMENT ADVISER AND ADMINISTRATOR

    The Trust's board has approved an Investment Advisory and Administration
Contract ("Advisory Contract") with Mitchell Hutchins, under which Mitchell
Hutchins serves as investment adviser and administrator of the Fund. In
accordance with the Advisory Contract, the Fund pays Mitchell Hutchins an
investment advisory and administration fee, which is accrued daily and paid
monthly, at an annual rate of 0.50% of the Fund's average daily net assets up to
$250 million and 0.45% thereafter. At August 31, 1999, the Fund owed Mitchell
Hutchins $957,372 in investment advisory and administration fees. Mitchell
Hutchins waived a portion of its investment advisory and administration fees in
connection with the Fund's investment of cash collateral from security lending
in the Mitchell Hutchins Private Money Market Fund LLC. For the year ended
August 31, 1999, Mitchell Hutchins waived $74,037.

    For the year ended August 31, 1999, the Fund paid $3,571 in brokerage
commissions to PaineWebber for transactions executed on behalf of the Fund.

DISTRIBUTION PLANS

    Mitchell Hutchins is the distributor of the Fund's shares and has appointed
PaineWebber as the exclusive dealer for the sale of those shares. Under separate
plans of service and/or distribution pertaining to Class A, Class B and Class C
shares, the Fund pays Mitchell Hutchins monthly service fees at an annual rate
of 0.25% of the average daily net assets of Class A, Class B and Class C shares
and monthly distribution fees at the annual rate of 0.75% of the average daily
net assets of Class B and Class C shares. At August 31, 1999, the Fund owed
Mitchell Hutchins $1,579,414 in service and distribution fees.

    Mitchell  Hutchins  also  receives the proceeds of the initial sales charges
paid by  shareholders  upon the  purchase  of Class A shares and the  contingent
deferred sales charges paid by shareholders upon certain redemptions of Class A,
Class B and Class C shares. Mitchell Hutchins has informed the Fund that for the
year ended August 31, 1999,  it earned  $7,097,653  in sales  charges.

TRANSFER AGENCY SERVICE FEES

    PaineWebber provides transfer agency related services to the Fund pursuant
to a delegation of authority from PFPC, Inc., the Fund's transfer agent, and is
compensated for the services by PFPC, Inc., not the Fund. For the year ended
August 31, 1999, PaineWebber received from PFPC, Inc., not the Fund,
approximately 55% of the total transfer agency and related service fees
collected by PFPC, Inc. from the Fund.

SECURITY LENDING

    The Fund may lend securities up to 331/3% of its total assets to qualified
institutions. The loans are secured at all times by cash or U.S. government
securities in an amount at least equal to the market value of the securities
loaned, plus accrued

interest, determined on a daily basis and adjusted accordingly. The Fund will
regain record ownership of loaned securities to exercise certain beneficial
rights however, the Fund may bear the risk of delay in recovery of, or even loss
of rights in, the securities loaned should the borrower fail financially. The
Fund receives compensation, which is included in interest income, for lending
its securities from interest earned on the cash or U.S. government securities
held as collateral, net of fee rebates paid to the borrower plus reasonable
administrative and custody fees. For the year ended August 31, 1999, the Fund
earned $371,252 for lending its securities and PaineWebber earned $176,811 in
compensation as the Fund's lending agent. At August 31, 1999, the Fund owed
PaineWebber $17,580 in compensation.

    As of August 31, 1999, the Fund held cash and/or cash equivalents having an
aggregate value of $418,693,932 as collateral for portfolio securities loaned
having a market value of $403,252,113. The cash collateral was invested in the

BANK LINE OF CREDIT

    The Fund may borrow up to $10 million under a short-term unsecured line of
credit with the Fund's custodian ("Line of Credit") and may participate with
other funds managed by Mitchell Hutchins in a $200 million committed credit
facility ("Facility") to be utilized for, temporary financing until the
settlement of sale or purchase of portfolio securities, the repurchase or
redemption of shares of the Fund at the request of the shareholders and other
temporary or emergency purposes.

    Under the Facility arrangement, the Fund has agreed to pay a commitment fee,
pro rata, based on the relative asset size of the funds in the Facility.
Interest is charged to the Fund at rates based on prevailing market rates in
effect at the time of borrowings. For the year ended August 31, 1999, the Fund
did not borrow under the Facility and had an average daily amount of borrowing
outstanding under the Line of Credit of $2,498,080 with a related weighted
average annualized interest rate of 5.79%.

              investments  were  as  follows:

          Gross appreciation (investments having an excess
            of value over cost) ................................   $619,956,261
          Gross depreciation (investments having an excess
            of cost over value) ................................    (64,558,177)
                                                                   ------------
          Net unrealized appreciation of investments ...........   $555,398,084
                                                                   ------------

FEDERAL TAX STATUS

    The Fund intends to distribute substantially all of its taxable income and
to comply with the other requirements of the Internal Revenue Code applicable to
regulated investment companies. Accordingly, no provision for federal income
taxes is required. In addition, by distributing during each calendar year
substantially all of its net investment income, capital gains and certain other
amounts, if any, the Fund intends not to be subject to a federal excise tax.

    To reflect reclassifications for the Tactical Allocation Fund arising from
permanent "book/tax" differences for the year ended August 31, 1999,

accumulated net realized gains from investment transactions were decreased by
$432,247 and beneficial interest was decreased by $6,902.

**   Investment advisory functions for the Fund were transferred from Kidder,
     Peabody Asset Management, Inc. to Mitchell Hutchins on February 13, 1995.

 @   Calculated using the average shares outstanding for the period.

(1)  Total investment return is calculated assuming a $1,000 investment on the
     first day of each period reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each period reported. The figures do not
     include sales charges or program fees; results would be lower if sales
     charges or program fees were included. Total investment return for periods
     of less than one year has not been annualized.

(2)  During the year ended August 31, 1999, Mitchell Hutchins waived a portion
     of its advisory and administration fees. The ratios excluding the waiver
     would be the same since the fee waiver represents less than 0.005%.

 #   Actual amount is less than $0.005.

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT AUDITORS

To the Shareholders and Trustees of
PaineWebber Tactical Allocation Fund

We have audited the accompanying statement of assets and liabilities of
PaineWebber Tactical Allocation Fund, including the portfolio of investments, as
of August 31, 1999, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We have conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned at August 31, 1999, by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
PaineWebber Tactical Allocation Fund at August 31, 1999, and the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the financial highlights for each of
the five years in the period then ended, in conformity with generally accepted
accounting principles.

* Taxable as ordinary income.

    Dividends received by tax-exempt recipients (e.g., IRAs and Keoghs) need not
be reported as taxable income. Some retirement trusts (e.g., corporate, Keogh
and 403(b)(7) plans) may need this information for their annual information
reporting.

    Since the Fund's fiscal year is not the calendar year, another notification
will be sent in respect of calendar year 1999. The second notification, which
will reflect the amount to be used by calendar year taxpayers on their federal
income tax returns, will be made in conjunction with Form 1099 DIV and will be
mailed in January 2000. Shareholders are advised to consult their own tax
advisers with respect to the tax consequences of their investment in the Fund.

                                                                              25
