                                          YORK 10048
LETTER TO THE SHAREHOLDERS MARCH 31, 1996
 
DEAR SHAREHOLDER:
 
The six month period ended March 31, 1996 was marked by a relatively quiet
fourth quarter of calendar 1995 and a relatively strong first quarter of
calendar 1996. As the fiscal year began in October 1995, a weakening U.S.
economy, benign inflation and robust corporate earnings combined to propel the
stock market to new heights and interest rates lower. By February, however, the
economy was showing signs of renewed vigor. Fear of a resurgence in inflation
and the belief that the Federal Reserve Board would not cut interest rates sent
the bond markets reeling and interest rates up.
 
Since December, convertible securities have performed well due to a strong stock
market and bucking the trend of the weak bond market. Small caps have also
performed well during the first three months of 1996, after lagging during the
second half of last year.
 
PERFORMANCE
 
Against this backdrop, Dean Witter Convertible Securities Trust posted a total
return of 7.33 percent for the six month period ended March 31, 1996, compared
to an average return of 7.26 percent for the funds in the Lipper convertible
securities fund category and a return of 11.70 percent for the broad-based
Standard & Poor's 500 Composite Stock Price Index (S&P 500 Index). The Fund's
small-cap concentration contributed to its strong performance during the first
quarter of 1996, as small-cap issues outperformed their larger-cap counterparts.
On March 31, 1996, the Fund's net assets exceeded $209 million. The Fund paid
distributions totaling $0.36 per share during the period, including an extra
income dividend of $.119 per share paid on December 29, 1995.
 
In December 1995, following approval by the shareholders of TCW/DW Global
Convertible Trust, the assets of that Fund were acquired by Dean Witter
Convertible Securities Trust. In addition, a special meeting of shareholders of
Dean Witter Convertible Securities Trust was held for the purpose of amending
the Fund's Plan of Distribution under
<PAGE>
DEAN WITTER CONVERTIBLE SECURITIES TRUST
LETTER TO THE SHAREHOLDERS MARCH 31, 1996, CONTINUED
 
Rule 12b-1 in connection with the acquisition of the assets of TCW/DW Global
Convertible Trust. The results of this vote are found elsewhere in this report.
 
As a result of the acquisition, the Fund's assets increased by approximately 10
percent. In addition, a number of small positions now exist in the portfolio,
with some holdings being foreign issuers. All foreign holdings are
dollar-denominated bonds and we remain very comfortable with these positions.
However, we do not expect to significantly increase our exposure to foreign
issues above the current five percent level.
 
INVESTMENT STRATEGY
 
The Fund uses a value-oriented, bottom-up approach to evaluate companies and
their investment merits. The Fund's emphasis is on companies and industries with
strong underlying fundamentals and solid long-term growth potential. We focus on
underfollowed, small- and medium-capitalization companies that issue convertible
securities which we believe offer excellent participation in a rising equity
market and downside protection in a declining market. As of March 31, 1996, the
Fund had exposure to a broad range of industries including health care (9
percent), real estate investment trusts (10 percent of assets), restaurants (4
percent) and retail (2 percent). Approximately 10 percent of the Fund's assets
were invested in common stocks in order to diversify the Fund's holdings into
industries and companies not represented in the convertible universe. In
addition, a portion of the Fund's assets were invested in high coupon securities
to help maintain a minimum income level. Among the Fund's strongest performers
during the period were Reno Air Inc., Safeguard Scientifics, Inc., Coleman
Worldwide Corp., Conseco, Inc. and WHX Corp.
 
In an attempt to control volatility, the Fund generally concentrates on issues
with short maturities, while diversifying its assets across a wide range of
industries. The Fund also searches for convertible securities with good
risk/reward characteristics. These characteristics include a relatively high
yield to support the convertible if the underlying stock declines and reasonable
conversion premium to ensure participation in any appreciation of the underlying
stock.
 
LOOKING AHEAD
 
We expect the U.S. economy to maintain a slow-to-moderate pace during the
remainder of 1996, and we believe that the Federal Reserve Board will continue
to make modest adjustments to monetary policy if evidence of weak economy
re-emerges. Inflation should continue to remain subdued albeit at a slightly
higher level in the year ahead. Given this scenario, we continue to believe
convertible securities currently offer good value with an attractive combination
of income and equity exposure.

DEAN WITTER CONVERTIBLE SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1996 (UNAUDITED)
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Convertible Securities 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 was organized as a
Massachusetts business trust on May 21, 1985 and commenced operations on October
31, 1985.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the
New York or American 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 a security
is traded on more than one exchange, the security is valued on the exchange
designated as the primary market 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 the Investment Manager 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; (4) certain portfolio securities
may be valued by an outside pricing service approved by the Trustees. The
pricing service utilizes a matrix system incorporating security quality,
maturity and coupon as the evaluation model parameters, and/or research and
evaluations by its staff, including review of broker-dealer market price
quotations, if available, in determining what it believes is the fair valuation
of the portfolio securities valued by such pricing service; and (5) 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 by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.
 
C. 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.
<PAGE>
DEAN WITTER CONVERTIBLE SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1996 (UNAUDITED) CONTINUED
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record 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 AGREEMENT
 
Pursuant to an Investment Management Agreement with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays a management fee, accrued daily
and payable monthly, by applying the following annual rates to the Fund's net
assets determined as of the close of each business day: 0.60% to the portion of
daily net assets not exceeding $750 million; 0.55% to the portion of daily net
assets exceeding $750 million but not exceeding $1 billion; 0.50% to the portion
of daily net assets exceeding $1 billion but not exceeding $1.5 billion; 0.475%
to the portion of daily net assets exceeding $1.5 billion but not exceeding $2
billion; 0.45% to the portion of daily net assets exceeding $2 billion but not
exceeding $3 billion; and 0.425% to the portion of daily net assets exceeding $3
billion.
 
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 pursuant
to which the Fund pays the Distributor compensation, accrued
<PAGE>
DEAN WITTER CONVERTIBLE SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1996 (UNAUDITED) CONTINUED
 
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 may be recovered through future distribution fees from the
Fund and contingent deferred sales charges from the Fund's shareholders.
 
The Distributor has informed the Fund that for the six months ended March 31,
1996, it received approximately $68,000 in contingent deferred sales charges
from certain 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 six months ended March 31, 1996 aggregated
$185,463,564 and $185,166,919, respectively.
 
For the same period, the Fund incurred brokerage commissions of $8,202 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, 1996, the Fund had
transfer agent fees and expenses payable of approximately $60,000.
 
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 six months ended March 31 1996
included in Trustees' fees and expenses in the Statement of Operations amounted
to $5,104. At March 31, 1996, the Fund had an accrued pension liability of
$49,420 which is included in accrued expenses in the Statement of Assets and
Liabilities.
