LETTER TO THE SHAREHOLDERS MARCH 31, 1997
 
DEAR SHAREHOLDER:
 
During the Fund's fiscal year ended March 31, 1997, global investment returns
continued to underperform those in the United States, with the Standard & Poor's
500 Composite Stock Index (S&P 500) advancing 19.84 percent while the Morgan
Stanley Capital International World Index (MSCI World Index) returned 7.68
percent.
 
European markets enjoyed strong performance, however, with Spain up 30.4
percent, the United Kingdom up 28.7 percent and Germany up 20.6 percent. Most
European equity markets responded well to the favorable macroeconomic outlook of
noninflationary growth induced by low interest rates, weaker domestic currencies
and tight fiscal policy. As 1997 unfolds, it will become more apparent which
countries will comply with the Maastricht criteria for participation in the
Economic and Monetary Union (EMU) when it begins in 1999.
 
Emerging markets also performed well over the last year. The Latin American
markets in particular rallied sharply, with Brazil up 56.0 percent, Argentina up
29.9 percent and Mexico up 19.0 percent. Southeast Asian markets advanced in
1996 but gave up gains in the first quarter of 1997 as a result of weakness in
technology and fears regarding interest rates.
 
In the United States, the Federal Reserve's Open Market Committee increased
interest rates on March 25 in response to signs of economic strength. Volatility
in most markets has since picked up as investors digest the prospects for
additional interest-rate increases. It should be noted that the economies of
Europe and Japan and emerging markets are all at different points in the
economic growth cycle. While all are affected by global liquidity, monetary
policy in these areas is set according to domestic trends in growth and
inflation.
 
PERFORMANCE AND PORTFOLIO
 
For the twelve-month period ended March 31, 1997, Dean Witter World Wide
Investment Trust provided a total return of 1.61 percent compared to 7.68
percent for the MSCI World Index and 11.85 percent for the

Lipper Global Funds Index. The accompanying chart illustrates the growth of a
$10,000 investment in the Fund for the ten-year period ended March 31, 1997,
versus similar investments in the MSCI World Index and the Lipper Global Funds
Index.
 
The main reason for the Fund's
underperformance versus its benchmarks
was the result of the Fund's year-long
overweighted position in the Japanese
equity market. The Fund's asset
allocation strategically overweighted
Japan because of improving signs there
of sustainable economic growth, a
depreciating yen, potential
deregulation measures and a sharp
profit recovery. Despite these
promising fundamentals, the Japanese
equity market, down 25.70 percent,
suffered a loss of confidence when
confronted with persistent bad press
documenting the fragility of the
financial sector. Faced with
deteriorating fundamentals and poor
sentiment, the Fund reduced its
exposure to Japan at the end of 1996 to
be at a neutral weighting versus the
MSCI World Index.
 
Dean Witter World Wide Investment Trust
is broadly invested across 25 global
markets. The Fund's target asset
allocation is Europe, 35 percent; U.S.,
25 percent; Japan, 20 percent; emerging
Asia, 12.5 percent; Latin America, 6.5
percent; and other, 1 percent. The
Fund's holdings include companies such
as PepsiCo Inc. (U.S., beverages),
Telecomunicacoes Brasileiras S.A.
(Brazil, telecommunications), AXA-UAP
(France, insurance), Volkswagen AG
(Germany, automobiles), Hutchison
Whampoa Ltd. (Hong Kong, conglomerate)
and Canon, Inc. (Japan, electrical
equipment).

LOOKING AHEAD
 
We believe that global equities continue to offer an attractive investment
opportunity. Continental European equities remain responsive to the dual profit
drivers of restructuring and improving competitiveness from weak domestic
currencies. In Japan, business confidence is building as exports pick up and
prospects for broader economic growth appear. Lastly, economic activity in Asian
and Latin American emerging markets is outpacing growth in the developed world.
 
We appreciate your support of Dean Witter World Wide Investment Trust and look
forward to continuing to serve your investment needs.
 
Very truly yours,

DEAN WITTER WORLD WIDE INVESTMENT TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter World Wide Investment Trust (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is total
return on its assets primarily through long-term capital growth and to a lesser
extent, from income. The Fund seeks to achieve its objective by investing in
common stocks and equivalents, preferred stocks, bonds and other debt
obligations of domestic and foreign companies, governments and international
organizations. The Fund was organized as a Massachusetts business trust on July
7, 1983 and commenced operations on October 31, 1983.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest 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 pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Dean Witter InterCapital Inc. (the "Investment Manager") or Morgan
Grenfell Investment Services Limited (the "Sub-Adviser") that sale and bid
prices are not reflective of a security's market value, portfolio securities are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Trustees (valuation of
debt securities for which market quotations are not readily available may be
based upon current market prices of securities which are comparable in coupon,
rating and maturity or an appropriate matrix utilizing similar factors); and (4)
short-term debt securities having a maturity date of more than sixty days at
time of purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined
<PAGE>
DEAN WITTER WORLD WIDE INVESTMENT TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
by the identified cost method. Dividend income and other distributions are
recorded on the ex-dividend date except for certain dividends on foreign
securities which are recorded as soon as the Fund is informed after the
ex-dividend date. Discounts are accreted over the life of the respective
securities. Interest income is accrued daily.
 
C. OPTION ACCOUNTING PRINCIPLES -- When the Fund purchases a call or put option,
the premium paid is recorded as an investment which is subsequently
marked-to-market to reflect the current market value. If a purchased option
expires, the Fund will realize a loss to the extent of the premium paid. If the
Fund enters into a closing sale transaction, a gain or loss is realized for the
difference between the proceeds from the sale and the cost of the option. If a
put option is exercised, the cost of the security or currency sold upon exercise
will be increased by the premium originally paid. If a call option is exercised,
the cost of the security purchased upon exercise will be increased by the
premium originally paid.
 
D. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are
maintained in U.S. dollars as follows: (1) the foreign currency market value of
investment securities, other assets and liabilities and forward foreign currency
contracts are translated at the exchange rates prevailing at the end of the
period; and (2) purchases, sales, income and expenses are translated at the
exchange rates prevailing on the respective dates of such transactions. The
resultant exchange gains and losses are included in the Statement of Operations
as realized and unrealized gain/loss on foreign exchange transactions. Pursuant
to U.S. Federal income tax regulations, certain foreign exchange gains/losses
included in realized and unrealized gain/loss are included in or are a reduction
of ordinary income for federal income tax purposes. The Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the changes in the market prices of the securities.
 
E. FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward foreign
currency contracts which are valued daily at the appropriate exchange rates. The
resultant unrealized exchange gains and losses are included in the Statement of
Operations as unrealized gain/loss on foreign exchange transactions. The Fund
records realized gains or losses on delivery of the currency or at the time the
forward contract is extinguished (compensated) by entering into a closing
transaction prior to delivery.
 
F. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.

DEAN WITTER WORLD WIDE INVESTMENT TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
G. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains 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. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
2. INVESTMENT MANAGEMENT AND ADVISORY AGREEMENTS
 
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 1.0% to the portion of daily net assets not exceeding $500
million and 0.95% to the portion of daily net assets in excess of $500 million.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services as the Fund may reasonably
require in the conduct of its business and also bears the cost of telephone
services, heat, light, power and other utilities provided to the Fund.
 
Under a Sub-Advisory Agreement between the Sub-Adviser and the Investment
Manager, the Sub-Adviser provides the Fund with investment advice and portfolio
management relating to the Fund's non-U.S. investments, subject to the overall
supervision of the Investment Manager. As compensation for its services provided
pursuant to the Sub-Advisory Agreement, the Investment Manager pays the
Sub-Adviser monthly compensation equal to 40% of its monthly compensation.
 
3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to
<PAGE>
DEAN WITTER WORLD WIDE INVESTMENT TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
Rule 12b-1 under the Act pursuant to which the Fund pays the Distributor
compensation, accrued daily and payable monthly, at an annual rate of 1.0% of
the lesser of: (a) the average daily aggregate gross sales of the Fund's shares
since the Fund's inception (not including reinvestment of dividend or capital
gain distributions) less the average daily aggregate net asset value of the
Fund's shares redeemed since the Fund's inception upon which a contingent
deferred sales charge has been imposed or upon which such charge has been
waived; or (b) the Fund's average daily net assets. Amounts paid under the Plan
are paid to the Distributor to compensate it for the services provided and the
expenses borne by it and others in the distribution of the Fund's shares,
including the payment of commissions for sales of the Fund's shares and
incentive compensation to, and expenses of, the account executives of Dean
Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, and other employees or selected broker-dealers who engage in or
support distribution of the Fund's shares or who service shareholder accounts,
including overhead and telephone expenses, printing and distribution of
prospectuses and reports used in connection with the offering of the Fund's
shares to other than current shareholders and preparation, printing and
distribution of sales literature and advertising materials. In addition, the
Distributor may be compensated under the Plan for its opportunity costs in
advancing such amounts, which compensation would be in the form of a carrying
charge on any unreimbursed expenses incurred by the Distributor.
 
Provided that the Plan continues in effect, any cumulative expenses incurred but
not yet recovered by the Distributor may be recovered through future
distribution fees from the Fund and contingent deferred sales charges from the
Fund's shareholders.
 
Although there is no legal obligation for the Fund to pay expenses incurred in
excess of payments made to the Distributor under the Plan and the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares,
if for any reason the Plan is terminated, the Trustees will consider at that
time the manner in which to treat such expenses. The Distributor has advised the
Fund that such excess amounts, included carrying charges, totaled $20,399,997 at
March 31, 1997.
 
The Distributor has informed the Fund that for the year ended March 31, 1997, it
received approximately $803,000 in contingent deferred sales charges from
redemptions of the Fund's shares.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended March 31, 1997 aggregated
$232,691,627 and $356,048,768, respectively.

DEAN WITTER WORLD WIDE INVESTMENT TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
For the year ended March 31, 1997, the Fund incurred brokerage commissions of
$16,375 with DWR for portfolio transactions executed on behalf of the Fund.
 
Dean Witter Trust Company, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At March 31, 1997, the Fund had
transfer agent fees and expenses payable of approximately $148,000.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended March 31, 1997 included
in Trustees' fees and expenses in the Statement of Operations amounted to
$1,290. At March 31, 1997, the Fund had an accrued pension liability of $49,252
which is included in accrued expenses in the Statement of Assets and
Liabilities.
 
During the year ended March 31, 1997, foreign regulatory authorities initiated
an investigation involving an individual associated with an affiliate of the
Fund's Sub-Adviser. Although this investigation did not at any time involve the
Fund or the Investment Manager, the Sub-Adviser's affiliate purchased from the
Fund two securities whose separate holdings by the affiliate had become part of
the investigation. These securities represented only a very small percentage of
the Fund's portfolio (approximately one-twentieth of one percent) and were
purchased by the Sub-Adviser's affiliate at the Fund's cost plus interest.

6. FEDERAL INCOME TAX STATUS
 
Foreign currency losses incurred after October 31 ("post-October losses") within
the taxable year are deemed to arise on the first business day of the Fund's
next taxable year. The Fund incurred and will elect to defer net foreign
currency losses of approximately $296,000 during fiscal 1997.
 
As of March 31, 1997, the Fund had temporary book/tax differences primarily
attributable to post-October losses and income from the mark-to-market of
passive foreign investment companies ("PFICs") and permanent book/tax
differences primarily attributable to a net operating loss, foreign currency
losses and tax adjustments on PFICs sold by the Fund. To reflect
reclassifications arising from permanent book/tax differences for the year ended
March 31, 1997, accumulated undistributed net realized gain was charged
$4,586,743, paid-in-capital was credited $581,060 and net investment loss was
credited $4,005,683.
 
7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
 
The Fund may enter into forward foreign currency contracts ("forward contracts")
to facilitate settlement of foreign currency denominated portfolio transactions
or to manage foreign currency exposure associated with foreign currency
denominated securities.
 
Forward contracts involve elements of market risk in excess of the amounts
reflected in the Statement of Assets and Liabilities. The Fund bears the risk of
an unfavorable change in the foreign exchange rates underlying the forward
contracts. Risks may also arise upon entering into these contracts from the
potential inability of the counterparties to meet the terms of their contracts.
 
At March 31, 1997, there were outstanding forward contracts used to facilitate
settlement of foreign currency denominated portfolio transactions.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER WORLD WIDE INVESTMENT TRUST
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter World Wide Investment
Trust (the "Fund") at March 31, 1997, 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 ten years in the
period then ended, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at March
31, 1997 by correspondence with the custodian and brokers and the application of
alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.
