Dear Shareholder,

We are pleased to present you with the semiannual report for the PaineWebber 
Tactical Allocation Fund (the "Fund") for the six-month period ended February 
28, 1999.

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

[GRAPHIC] The stock market, as measured by S&P 500 Index (the "Index"), 
gained 30.27% for the six-month period ended February 28, 1999. As the period 
began, the market had just lost 14.45% in August 1998. Stock prices came back 
through the period, but endured considerable volatility along the way. The 
Federal Reserve reduced short-term interest rates to quell investor 
anxieties, and the market -- led by technology stocks -- rebounded with strong 
gains at the end of 1998. Prices remained volatile, however, and the Index 
posted a much lower gain in January 1999. Investors began to worry that 
inflation might heat up and cause interest rates to rise again. Concerns 
about decreasing demand for personal computers and a potential for year 2000 
disruptions hurt technology stock prices. The Index lost 3.11% in February, 
its first monthly loss since August.

PORTFOLIO REVIEWS
- --------------------------------------------------------------------------------

PERFORMANCE --
[GRAPHIC] The Fund's total return consists of the change in net asset value 
with dividends reinvested. For the six-month period ended February 28, 1999, 
without deducting sales charges, Class A shares gained 29.67%, Class B shares 
gained 29.24%, Class C shares gained 29.18% and Class Y shares gained 29.91%.

     The Fund's total return may be lower for shareowners who purchased or 
redeemed Fund shares during the period. After deducting the maximum 
applicable sales charges, Class A shares gained 23.83%, Class B shares gained 
24.24% and Class C shares gained 28.18%. Class Y shares are not subject to 
sales charges.

PORTFOLIO HIGHLIGHTS --

     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 the 
risk premium -- the return advantage -- of stocks and bonds. The Model 
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).

     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 

                                                                               1

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.

     Throughout the six-month period, the equity risk premium remained above 
the 5.5% hurdle rate -- and as a result, the Fund remained 100% invested in 
equities. The ERP declined from 6.62 at the start of the period to 5.92 at the 
end. This decline was attributable to increasing stock prices; there was 
little change in other factors that affect the ERP, such as interest rates or 
dividend growth expectations.

     During the six-month period ended February 28, 1999, the Fund's 
weightings in financial services and technology companies increased, 
reflecting changes in the market weightings of these sectors in the S&P 500 
Index (see table below).

OUTLOOK
- --------------------------------------------------------------------------------
[GRAPHIC] The economy is sending mixed signals -- auto sales look strong but 
airline traffic has been weak. Unemployment is down, but inflation does not 
seem to be rising. We'll be watching for a clear signal on interest rates from 
the Federal Reserve, but right now it looks as if monetary policy will remain 
on hold.

     As the next reporting period began the Fund remained 100% invested in 
equities. The Fund's next move will depend upon the interactions of the 
variables in the Model -- short-term interest-rate moves, stock valuations and 
changes in dividend growth expectations.

* Portfolio weightings represent percentages of net assets as of February 28, 
1999 except where noted otherwise. Portfolio composition will vary over time.

   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.
 
   The data above represents past performance of the Fund's shares, which is no

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--Securities that are listed on stock exchanges are
valued at the last sale price on the day the securities are being 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 by Mitchell Hutchins Asset Management Inc. ("Mitchell
Hutchins"), an asset management subsidiary of PaineWebber Incorporated
("PaineWebber") and investment adviser, administrator and distributor of the
Fund. Securities traded in the over-the-counter ("OTC") market and listed on the
Nasdaq Stock Market, Inc. ("Nasdaq") are valued at the last available sale
price, or last bid price available if no sale occurs, on Nasdaq prior to the
time of valuation. Where market quotations are readily available, debt
securities are valued thereon, provided such quotations adequately reflect the
fair value of the securities in the judgment of Mitchell Hutchins. When market
quotations are not readily available, securities are valued based upon
appraisals derived from information concerning those securities or similar
securities received from recognized dealers in those securities. All other
securities are valued at fair value as determined in good faith by, or under the
direction of, the Trust's board of trustees. The amortized cost method of
valuation is used to value short-term debt securities with sixty days or less
remaining to maturity, unless the Trust's board of trustees 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.
 
                                       16
<PAGE>
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
  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 of trustees 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 February 28, 1999, the Fund owed Mitchell
Hutchins $696,927 in investment advisory and administration fees.
 
  For the six months ended February 28, 1999, the Fund paid $2,279 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 the 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 February 28, 1999, the Fund owed
Mitchell Hutchins $1,141,290 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 six
months ended February 28, 1999, it earned $3,123,902 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 six months
ended February 28, 1999, PaineWebber received from PFPC, Inc., not the Fund,
approximately 57% 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 33 1/3% 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
 
                                       17

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
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 six months ended February 28, 1999, the Fund earned $67,723 for lending
its securities and PaineWebber earned $83,074 in compensation as the Portfolio's
lending agent. At February 28, 1999, the Fund owed PaineWebber $8,161 in
compensation.
 
  As of February 28, 1999, the Fund held cash and/or cash equivalents having an
aggregate value of $206,014,400 as collateral for portfolio securities loaned
having a market value of $196,872,531. The cash collateral was invested in the
following money market funds.

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 six months ended February 28, 1999,
the Fund did not borrow under the Facility and had an average daily amount of
borrowing outstanding under the Line of Credit of $2,839,996 with a related
weighted average annualized interest rate of 5.90%.

**   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.
 #   Amount shown is less than $0.005.

     charges or program fees were included. Total investment return for periods
