DEAN WITTER INFORMATION FUND    Two World Trade Center, New York, New York 10048
 
LETTER TO THE SHAREHOLDERS September 30, 1997
 
DEAR SHAREHOLDER:
 
Dean Witter Information Fund continues to pursue its objective of long-term
capital appreciation by investing in all aspects of the communication and
information industry. The Fund focuses on companies that exhibit proven
management, proprietary technologies or barriers to entry, and strategic
relationships or alliances. As of September 30, 1997, the Fund's net assets
stood at approximately $255 million.
 
PERFORMANCE REVIEW
 
During the six-month period ended September 30, 1997, the Fund's Class B shares
provided a total return of 35.05 percent versus 40.75 percent for the Lipper
Analytical Services, Inc. Science and Technology Funds Index and 26.24 percent
for the Standard & Poor's 500 Composite Stock Price Index (S&P 500). During the
period, the Fund's Class B net asset value (NAV) rose from $8.94 to $12.06. The
sectors which helped the Fund outperform the S&P 500 included Internet-related
stocks, radio broadcasters and emerging telecommunications carriers -- both
wireline and wireless -- and firms that provide technology to these
telecommunication companies.
 
PORTFOLIO POSITION
 
Over the past six months several significant events occurred within the
communication and information arena to confirm our enthusiasm for these sectors.
First, a surge of advertising and commerce deals on the World Wide Web (the Web
is the graphical- and consumer-oriented portion of the Internet) drove interest
in such companies as America Online, Inc. (AOL) and Excite, Inc.
 
Second, a considerable increase in customer additions, initial public offerings
and acquisitions contributed to strong performance in the emerging
telecommunications industry. Significant acquisitions during the period
included: LCI International, Inc. purchasing U.S. Long Distance; WorldCom, Inc.
buying CompuServe's and AOL's Internet networks and WorldCom, Inc. buying Brook
Fiber Properties, Inc. In addition,

LETTER TO THE SHAREHOLDERS September 30, 1997, continued
 
WorldCom, Inc. announced plans to acquire MCI in the largest acquisition ever in
the United States. Finally, Microsoft Corp. invested $1 billion in the cable TV
industry and is contemplating another $1 billion investment.
 
As of September 30, 1997, the Fund's greatest industry exposure was in media (27
percent of net assets), followed by telecommunication components and equipment
(26 percent), information services (22 percent) and telecommunication/cable
operating companies (19 percent). Ten percent of the Fund's net assets was held
in foreign securities and American Depositary Receipts, which are receipts
typically issued by a U.S. bank to evidence ownership of the underlying foreign
securities.
 
On July 28, 1997, the Fund began offering four classes of shares: A, B, C and D,
each with its own sales charge and distribution fee structure. A revised
prospectus, which includes complete details regarding the Fund's conversion to
multiple classes of shares, was mailed to shareholders in mid-summer.
 
LOOKING AHEAD
 
The fundamentals underpinning the communication and information sector remain
favorable. Operators continue to spend heavily on equipment and information
systems as they prepare for new competition, which has given consumers the
freedom to choose a service provider. The electronics sector is expected to
perform well in the long run as technology continues to represent more of
worldwide spending. The consolidation that has occurred within the broadcasting
industry has led to a greater control of prices, which points to continued
strong performance. With the growing popularity of advertising on the Internet,
emerging Web-based media stocks seem likely to attract a large piece of the
total $184 billion U.S. advertising pie, and Internet advertising should
eventually lead into overseas advertising as well. Service firms such as AOL,
E*Trade Group, Inc. and the wireless providers are attracting a tremendous
number of new subscribers, a trend that we expect to have a positive impact on
share prices of such companies going forward.
 
We appreciate your support of Dean Witter Information Fund and look forward to
continuing to serve your investment needs.
 
Very truly yours,
 
/S/ CHARLES A. FIUMEFREDDO

Chairman of the Board

DEAN WITTER INFORMATION FUND
 
NOTES TO FINANCIAL STATEMENTS September 30, 1997 (unaudited)
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Information Fund (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 long-term
capital appreciation. The Fund seeks to achieve its investment objective by
investing primarily in common stocks and securities convertible into common
stocks of domestic and foreign companies which are involved in the
communications and information industry. The Fund was organized as a
Massachusetts business trust on December 8, 1994 and commenced operations on
November 28, 1995. On July 28, 1997, the Fund commenced offering three
additional classes of shares, with the then current shares designated as Class B
shares.
 
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase, some Class
A shares, and most Class B shares and Class C shares are subject to a contingent
deferred sales charge imposed on shares redeemed within one year, six years and
one year, respectively. Class D shares are not subject to a sales charge.
Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
 
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") that sale
or 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; 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
<PAGE>   11
 
DEAN WITTER INFORMATION FUND
 
NOTES TO FINANCIAL STATEMENTS September 30, 1997 (unaudited) continued
 
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 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. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.
 
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 foreign currency gain or loss and in the Statement of
Assets and Liabilities as part of the related foreign currency denominated asset
or liability. 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 INFORMATION FUND
 
NOTES TO FINANCIAL STATEMENTS September 30, 1997 (unaudited) 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.
 
H. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $179,000 which have been
reimbursed for the full amount thereof. Such expenses have been deferred and are
being amortized on the straight-line method over a period not to exceed five
years from commencement of operations.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
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: 0.75% to the portion of daily net assets not exceeding
$500 million; and 0.725% to the portion of daily net assets exceeding $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 and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
 
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 Rule 12b-1 under the Act. The Plan
provides that the Fund will pay the Distributor a fee which is accrued daily and
paid monthly at the following annual rates: (i) Class A -- 0.25% of the average
daily
<PAGE>   13
 
DEAN WITTER INFORMATION FUND
 
NOTES TO FINANCIAL STATEMENTS September 30, 1997 (unaudited) continued
 
net assets of Class A; (ii) Class B -- 1.0% of the lesser of: (a) the average
daily aggregate gross sales of the Class B shares since the inception of the
Fund (not including reinvestment of dividend or capital gain distributions) less
the average daily aggregate net asset value of the Class B shares redeemed since
the Fund's inception upon which a contingent deferred sales charge has been
imposed or waived; or (b) the average daily net assets of Class B; and (iii)
Class C -- 1.0% of the average daily net assets of Class C. In the case of Class
A shares, amounts paid under the Plan are paid to the Distributor for services
provided. In the case of Class B and Class C shares, amounts paid under the Plan
are paid to the Distributor for services provided and the expenses borne by it
and others in the distribution of the shares of these Classes, including the
payment of commissions for sales of these Classes 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 others who engage in or
support distribution of the 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 these shares to
other than current shareholders; and preparation, printing and distribution of
sales literature and advertising materials. In addition, the Distributor may
utilize fees paid pursuant to the Plan, in the case of Class B shares, to
compensate DWR and other selected broker - dealers for their opportunity costs
in advancing such amounts, which compensation would be in the form of a carrying
charge on any unreimbursed expenses.
 
In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. 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, including
carrying charges, totaled $12,431,851 at September 30, 1997.
 
In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to account executives may be reimbursed in the subsequent
calendar year. For the period ended September 30, 1997, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
1.0%, respectively.
<PAGE>   14
 
DEAN WITTER INFORMATION FUND
 
NOTES TO FINANCIAL STATEMENTS September 30, 1997 (unaudited) continued
 
The Distributor has informed the Fund that for the six months ended September
30, 1997, it received contingent deferred sales charges from certain redemptions
of the Fund's Class B shares of $509,149 and received $3,177 in front-end sales
charges from sales of the Fund's Class A shares. The respective shareholders pay
such charges which are not an expense of the Fund.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended September 30, 1997 aggregated
$168,421,361, and $192,625,220, respectively.
 
For the six months September 30, 1997, the Fund incurred brokerage commissions
of $26,640 with DWR for portfolio transactions executed on behalf of the Fund.
 
For the period May 31, 1997 through September 30, 1997, the Fund incurred
brokerage commissions of $8,020 with Morgan Stanley & Co., Inc., an affiliate of
the Investment Manager since May 31, 1997, for portfolio transactions executed
on behalf of the Fund.
 
Dean Witter Trust FSB, an affiliate of the Investment Manager and Distributor,
is the Fund's transfer agent. At September 30, 1997, the Fund had transfer agent
fees and expenses payable of approximately $12,000.
 
5. FEDERAL INCOME TAX STATUS
 
At March 31, 1997, the Fund had a net capital loss carryover of approximately
$19,779,000 which will be available through March 31, 2005 to offset future
capital gains to the extent provided by regulations.
 
Capital and 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
capital and foreign currency losses of approximately $14,822,000 and $11,800,
respectively, during fiscal 1997.
 
As of March 31, 1997, the Fund had temporary book/tax differences primarily
attributable to post-October losses and capital loss deferrals on wash sales.

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 September 30, 1997, there were no outstanding forward contracts.
