PRINCIPAL RETURN FUND
ZEROS AND APPRECIATION SERIES 1996

 
DEAR SHAREHOLDER:
 
The first half of Smith Barney Shearson Principal Return Fund -- Zeros and
Appreciation Series 1996 fiscal year ended May 31, 1994 was certainly a
difficult period for the financial markets. Stocks had their most important
downward thrust since the summer of 1990, and the bond market had a decline
equivalent to a full-scale bear market. The yield on long-term treasury bonds
rose from 5.9% to 7.5%, creating large losses in many fixed income portfolios.
Despite the very poor environment, the Fund was essentially unchanged, gaining
eight-tenths of 1% during this period. In some ways, the past six months
demonstrated most strongly the validity of the original premise on which you
bought the Fund. The intermediate-term zero coupon treasury notes declined
in value, but since they mature in less than two years, the decline was
buffered considerably. The stock portfolio, filled as it is with high quality
securities, suffered far less than more speculative portfolios.
 
The recent decline in the financial markets had more to do with the cooling of
speculative excesses than with any fundamental deterioration in the economy.
The increase in short-term interest rates by the Federal Reserve led to an
exaggerated response in the bond market, but the economy should be able to
withstand the higher rates and grow at a moderate pace. Corporate earnings
should continue to improve as years of cost-cutting become reflected in the
bottom line of corporations. The over-exuberant attitude of stock market
participants has cooled, which is a much healthier state of affairs for the
market. We expect better results going into the second half of the year.
 
Over the past six months, we have continued to focus on companies and groups
where we feel expectations are unjustifiably low or have been significantly
reduced. During periods where we view the market as vulnerable, as we have in
the past few months, it is important to emphasize areas that are not extended 
or
overvalued. On this premise, we have added meaningfully to both Eastman Kodak
Company (Kodak) and American Telephone & Telegraph Company on their price
pullbacks earlier in the year. In the case of Kodak, we believe there is
significant upside in the stock as investors discover the value of its core
imaging business, its superior patent library, and management's new-found 
focus
on creating shareholder wealth. We added to American Telephone & Telegraph
Company as we continue to believe it will be one of the leaders in the
development of the information superhighway with its global network, 
attractive
portfolio of alliances and its marketing expertise. We also continue to have
solid representation in the cable stocks, TeleCommunications, Inc. and Comcast
Corporation, which although depressed, have been sufficiently washed out to
warrant a good bounce once their cable values get recognized through likely
mergers, alliances or joint ventures. A new position in Motorola, Inc. was
instituted as the stock price came down from its lofty heights. The company is
well
 
                                        1

positioned to participate in the growth of wireless communications and
semiconductor industries. We have also increased our positions in the rails,
specifically Burlington Northern, Inc. and Union Pacific Corporation, as an
extended play on the economy and the pickup in intermodal transport, further
amplified by their cost cutting efforts.
 
We continue to hold a core of great growth companies which include such names 
as
Gillette Company, Home Depot, Inc., Disney (Walt) Company, Johnson & Johnson,
and Microsoft Corporation. We believe that these superior growth companies 
will
continue to regain favor as we enter an environment where the economy no 
longer
gives such a dramatic edge to cyclical companies.
 
Our major themes have not changed since our year-end letter to you. We 
continue
to emphasize such themes as the reindustrialization of Middle America
(specifically autos), Telecommunications/Information and Restructuring
Candidates. Our restructuring theme, which has worked so well to date, 
provided
ample opportunity for profit taking. We continue to take profits in some of 
our
restructuring candidates which have had strong performance over the last few
quarters and may be approaching full value. These positions include such
companies as: Allied Signal, Inc., Xerox Corporation and Avon Products, Inc.
 
Additional sales in the Fund resulted from both eliminations of positions and
rebalancing of the portfolio. Partial profits were realized in duPont (E.I.),
deNemours & Company, Disney (Walt) Corporation, Minnesota Mining and
Manufacturing Company, Pepsico Inc., NationsBank Corporation, Intel 
Corporation,
General Electric Company, and Microsoft Corporation as stock appreciation had
created outsized holdings in the Fund. We eliminated disappointing positions 
in
Cooper Industries and Allstate, as well as profitable positions in Readers
Digest, Pep Boys, Grainer, Pfizer and Pacific Bell.
 
We believe our approach of owning quality companies and proven managements
remains valid. We will also continue to look for individual stocks that are
likely to resist further decline, and have the fundamentals to support future
price gains. We thank you for your continued support.
 
Sincerely,
 
/s/ Heath B. McLendon    /s/ Harry D. Cohen       /s/ Harold L. Williamson,

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.  SIGNIFICANT ACCOUNTING POLICIES
 
Smith Barney Shearson Principal Return Fund (the "Trust") was organized on
October 18, 1988, under the laws of the Commonwealth of Massachusetts as a
"Massachusetts business trust." The Trust is a diversified, open-end 
management
investment company registered with the Securities and Exchange Commission 
under
the Investment Company Act of 1940, as amended. The Trust consists of four
series, Zeros and Appreciation Series 1996, which commenced operations on
January 16, 1989, Zeros and Appreciation Series 1998 which commenced 
operations
on January 25, 1991, Zeros Plus Emerging Growth Series 2000, which commenced
operations on August 30, 1991, and Zeros Plus European Equities Series 1999
which has not yet commenced operations. Zeros and Appreciation Series 1996 
(the
"Fund") expects to terminate operations on March 1, 1996. The following is a
summary of significant accounting policies consistently followed by the Fund 
in
the preparation of its financial statements.
 
Portfolio valuation: Listed securities traded on a national securities 
exchange
are valued at the last reported sales price; securities traded in the
over-the-counter market and listed securities for which no sale was reported 
are
valued at the bid price or, in the absence of a recent bid price, at the bid
equivalent as obtained from one or more of the major market makers in the
securities. Investments in U.S. government securities (other than short-term
securities) are valued at the quoted bid price in the over-the-counter market.
Short-term investments that mature in 60 days or less are valued at amortized
cost whenever the Board of Trustees determines that amortized cost reflects 
the
fair value of those investments. Investments in securities for which market
quotations are not available are valued at fair value as determined in good
faith by the Board of Trustees.
 
Repurchase agreements: The Fund may engage in repurchase agreement 
transactions.
Under the terms of a typical repurchase agreement, the Fund takes possession 
of
an underlying debt obligation subject to an obligation of the seller to
repurchase, and the Fund to resell, the obligation at an agreed-upon price and
time, thereby determining the yield during the Fund's holding period. This
arrangement results in a fixed rate of return that is not subject to market
fluctuations during the Fund's holding period. The value of the collateral 
held
by the Fund is at least equal at all times to the total amount of the 
repurchase
obligations, including interest. In the event of counterparty default, the 
Fund
has the right to use the collateral to offset losses incurred. There is
potential loss to the Fund in the event that the Fund is
 
                                       13

delayed or prevented from exercising its rights to dispose of the collateral
securities, including the risk of a possible decline in the value of the
underlying securities during the period while the Fund seeks to assert its
rights. The Fund's investment adviser, acting under the supervision of the 
Board
of Trustees, reviews the value of the collateral and the creditworthiness of
those banks and dealers with which the Fund enters into repurchase agreements 
to
evaluate potential risks.
 
Securities transactions and investment income: Securities transactions are
recorded as of the trade date. Realized gains and losses from securities
transactions are recorded on the identified cost basis. Dividend income is
recorded on the ex-dividend date. Interest income is recorded on the accrual
basis (primarily from accretion of U.S. Treasury Notes).
 
Dividends and distributions to shareholders: Dividends from net investment
income and distributions of net realized capital gains of the Fund, if any, 
will
be distributed annually after the close of the fiscal year in which they are
earned. In addition, in order to avoid the application of a 4% nondeductible
excise tax on certain undistributed amounts of ordinary income and capital
gains, the Fund may make an additional distribution of any undistributed
ordinary income or capital gains shortly before December 31st of each year, 
and
expects to pay any other dividends and distributions as are necessary to avoid
the application of this tax. Income distributions and capital gain 
distributions
are determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. These differences are primarily due 
to
differing treatments of income and gains on various investment securities held
by the Fund, timing differences and differing characterization of 
distributions
made by the Fund as a whole.
 
Federal income taxes: It is the Fund's policy to comply with the requirements 
of
the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and to distribute substantially all of its taxable income
to its shareholders. Therefore, no Federal income tax provision is required.

2.  INVESTMENT ADVISORY FEE, ADMINISTRATION FEE AND OTHER TRANSACTIONS
 
The Trust has entered into an investment advisory agreement (the "Advisory
Agreement") with Smith Barney Asset Management, a division of Smith, Barney
Advisers, Inc. ("SBA"), which is controlled by Smith Barney Holdings Inc.
("Holdings"). Holdings is a wholly owned subsidiary of The Travelers Inc. 
Under
the advisory agreement, the Fund pays a monthly fee at the annual rate of .30%
of the value of its average daily net assets.
 
Prior to April 21, 1994, the Trust was party to an administration agreement 
with
The Boston Company Advisors, Inc. ("Boston Advisors"), an indirect wholly 
owned
subsidiary of Mellon Bank Corporation ("Mellon"). Under this agreement, the 
Fund
paid a monthly fee at the annual rate of .20% of the value of its average 
daily
net assets.
 
As of the close of business on April 21, 1994, SBA succeeded Boston Advisors 
as
the Fund's administrator. The new administration agreement contains
substantially the same terms and conditions, including the level of fees, as 
the
predecessor agreement.
 
As of the close of business on April 21, 1994, the Fund has also entered into 
a
sub-administration agreement (the "Sub-Administration Agreement") with Boston
Advisors. Under the Sub-Administration Agreement, Boston Advisors is paid a
portion of the fee paid by the Fund to SBA at a rate agreed upon from time to
time between SBA and Boston Advisors.
 
For the six months ended May 31, 1994, the Fund incurred total brokerage
commissions of $14,999 of which $690 was paid to Smith Barney, Inc. ("Smith
Barney").
 
No officer, director or employee of Smith Barney or any parent or subsidiary 
of
Smith Barney receives any compensation from the Trust for serving as a Trustee
or officer of the Trust. The Trust pays each Trustee who is not an officer,
director or employee of Smith Barney or any of its affiliates $2,000 per annum
plus $500 per meeting attended and reimburses each Trustee for travel and
out-of-pocket expenses.
 
Boston Safe Deposit and Trust Company, an indirect wholly owned subsidiary of
Mellon, serves as the Trust's custodian. The Shareholder Services Group, Inc., 
a
subsidiary of First Data Corporation, serves as the Trust's transfer agent.

The Fund and several affiliated entities participate in a $50 million line of
credit provided by Continental Bank N.A. under an Amended and Restated Line of
Credit Agreement (the "Agreement") dated April 30, 1992, primarily for 
temporary
or emergency purposes, including the meeting of redemption requests that
otherwise might require the untimely disposition of securities. Under this
Agreement, the Fund may borrow up to the lesser of $25 million or 20% of its 
net
assets. Interest is payable either at the bank's Money Market Rate or the 
London
Interbank Offered Rate (LIBOR) plus .375% on an annualized basis. The Fund and
the other affiliated entities are charged an aggregate commitment fee of

Agreement requires, among other provisions, each participating fund to 
maintain
a ratio of net assets (not including funds borrowed pursuant to the Agreement)
to aggregate amount of indebtedness pursuant to the Agreement of no less than 
5
to 1. During the six months ended May 31, 1994, the Fund had an average
outstanding daily balance of $48,901 with interest rates ranging from 3.31% to
3.94%. Interest expense totalled $1,231 for the six months ended May 31, 1994.
At May 31, 1994, the Fund had no outstanding borrowings under this Agreement.

sophisticated financial planning tool -- can help you and your FC evaluate 
your
resources and objectives. This groundwork then becomes the basis for a

proprietary system known as the Mutual Fund Evaluation Service, your FC can 
help
guide you through the complex mutual fund maze. Specifically, the Evaluation
Service can provide a clear picture of the past performance of mutual funds 
you
currently own. Presented in both graphic and numerical form, this illustration
provides a wealth of easily understood data on more than 2,100 funds. This
complimentary service allows you to judge whether your mutual fund has helped
meet your investment needs.
 
4. LOOKING AHEAD
 
Selecting a mutual fund should not be a one-event process that ends with the
purchase of shares. You can count on the expertise of your FC as he or she
continues to monitor and evaluate your funds, to suggest new strategies and to
listen. That, in our opinion, is how to use mutual funds to help achieve your
financial goals.

PRINCIPAL RETURN FUND
Zeros and Appreciation Series 1998


DEAR SHAREHOLDER:
 
The first half of Smith Barney Shearson Principal Return Fund -- Zeros  and
Appreciation Series 1998 fiscal year ended May 31, 1994 was certainly a
difficult period for the financial markets. Stocks had their most important
decline since the summer of 1990, and the bond market was battered by a
full-scale bear market. The yield on long-term treasury bonds rose from 5.9% 
to
7.5%, creating large losses in many fixed income portfolios. While the Fund
suffered a decline during this terribly difficult period, it was contained to 
a
loss of 2.26%. In some ways, the past six months demonstrated most strongly 
the
validity of the original premise on which you bought the Fund. The
intermediate-term zero coupon treasury notes declined in value, but since they
mature in just over four years, the decline was buffered considerably. The
stock portfolio, filled as it is with high quality securities, suffered far
less than more speculative portfolios.
 
The recent decline in the financial markets had more to do with the cooling of
speculative excesses than with any fundamental deterioration in the economy.
The increase in short-term interest rates by the Federal Reserve led to an
exaggerated response in the bond market, but the economy should be able to
withstand the higher rates and grow at a moderate pace. Corporate earnings
should continue to improve as years of cost-cutting become reflected in the
bottom line of corporations. The over-exuberant attitude of stock market
participants has cooled, which is a much healthier state of affairs for the
market. We expect better results going into the second half of the year.
 
Over the past six months, we have continued to focus on companies and groups
where we feel expectations are unjustifiably low or have been significantly
reduced. During periods where we view the market as vulnerable, as we have in
the past few months, it is important to emphasize areas that are not extended 
or
overvalued. On this premise, we have added meaningfully to both Eastman Kodak
Company (Kodak) and American Telephone & Telegraph Company, on their price
pullbacks earlier this year. In the case of Kodak, we believe there is
significant upside in the stock as investors discover the value of its core
imaging business, its superior patent library, and management's new-found 
focus
on creating shareholder wealth. We added to American Telephone & Telegraph
Company, as we continue to believe it will be one of the leaders in the
development of the information superhighway with its global network, 
attractive
portfolio of alliances and marketing expertise. We continue to have solid
representation in the cable stocks, TeleCommunications, Inc. and Comcast
Corporation, which although depressed have been sufficiently washed out to
warrant a good bounce once their cable values get recognized through likely
mergers, alliances or joint ventures. A new position in Motorola, Inc. was
instituted as the stock price came down from its lofty heights.
 
                                        1

<TABLE>
The company is well positioned to participate in the growth of wireless
communications and semiconductor industries. We have also increased our 
position
in the rails, specifically Burlington Northern, as an extended play on the
economy and the pickup in intermodal transport, further amplified by their 
cost
cutting efforts.
 
We continue to hold a core of great growth companies which include such names 
as
Gillette Company, Home Depot, Inc., Disney (Walt) Company, Johnson & Johnson,
and Microsoft Corporation. We believe that these superior growth companies 
will
continue to regain favor as we enter an environment where the economy no 
longer
gives a dramatic edge to cyclical companies.
 
Our major themes have not changed since our year-end letter to you. We 
continue
to emphasize such themes as the reindustrialization of Middle America
(specifically autos), Telecommunications/Information and Restructuring
Candidates. Our restructuring theme, which has worked so well to date, 
provided
ample opportunity for profit taking. We continue to take profits in some of 
our
restructuring candidates which have had strong performance over the last few
quarters and may be approaching full value. These positions include such
companies as: Allied Signal, Inc., Xerox Corporation and Avon Products, Inc.
 
Additional sales in the Fund resulted from both eliminations of positions and
rebalancing of the portfolio. Partial profits were realized in Unum 
Corporation,
Disney (Walt) Company, Minnesota Mining and Manufacturing Company, Pepsico 
Inc.,
Citicorp, Intel Corporation, Toys R Us, Inc., and Microsoft Corporation as 
stock
appreciation had created outsized holdings in the Fund. We eliminated
disappointing positions in Cooper Industries and Allstate, as well as 
profitable
positions in Nalco Chemical, Readers Digest, Pep Boys, Pfizer and Pacific 
Bell.
 
We believe our approach of owning quality companies and proven managements
remains valid. We will also continue to look for individual stocks that are
likely to resist further decline, and have the fundamentals to support future
price gains. We thank you for your continued support.
 
Sincerely,
 
<S>                      <C>                      <C>

1.  SIGNIFICANT ACCOUNTING POLICIES
 
Smith Barney Shearson Principal Return Fund (the "Trust") was organized on
October 18, 1988, under the laws of the Commonwealth of Massachusetts as a
"Massachusetts business trust." The Trust is a diversified, open-end 
management
investment company registered with the Securities and Exchange Commission 
under
the Investment Company Act of 1940, as amended. The Trust consists of four
series, Zeros and Appreciation Series 1996, which commenced operations on
January 16, 1989, Zeros and Appreciation Series 1998 which commenced 
operations
on January 25, 1991, Zeros Plus Emerging Growth Series 2000, which commenced
operations on August 30, 1991 and Zeros Plus European Equities Series 1999 
which
has not yet commenced operations. Zeros and Appreciation Series 1998 (the
"Fund") expects to terminate operations on August 31, 1998. The following is a
summary of significant accounting policies consistently followed by the Fund 
in
the preparation of its financial statements.
 
Portfolio valuation: Listed securities traded on a national securities 
exchange
are valued at the last reported sales price; securities traded in the
over-the-counter market and listed securities for which no sale was reported 
are
valued at the bid price or, in the absence of a recent bid price, at the bid
equivalent as obtained from one or more of the major market makers in the
securities. Investments in U.S. government securities (other than short-term
securities) are valued at the quoted bid price in the over-the-counter market.
Short-term investments that mature in 60 days or less are valued at amortized
cost whenever the Board of Trustees determines that amortized cost reflects 
the
fair value of those investments. Investments in securities for which market
quotations are not available are valued at fair value as determined in good
faith by the Board of Trustees.
 
Repurchase agreements: The Fund may engage in repurchase agreement 
transactions.
Under the terms of a typical repurchase agreement, the Fund takes possession 
of
an underlying debt obligation subject to an obligation of the seller to
repurchase, and the Fund to resell, the obligation at an agreed-upon price and
time, thereby determining the yield during the Fund's holding period. This
arrangement results in a fixed rate of return that is not subject to market
fluctuations during the Fund's holding period. The value of the collateral 
held
by the Fund is at least equal at all times to the total amount of the 
repurchase
obligations, including interest. In the event of counterparty default, the 
Fund
has the right to use the collateral to offset losses incurred. There is 
potential loss to the Fund in the event that the Fund is
 
                                       13

delayed or prevented from exercising its rights to dispose of the collateral
securities, including the risk of a possible decline in the value of the
underlying securities during the period while the Fund seeks to assert its
rights. The Fund's investment adviser, acting under the supervision of the 
Board
of Trustees, reviews the value of the collateral and the creditworthiness of
those banks and dealers with which the Fund enters into repurchase agreements 
to
evaluate potential risks.
 
Securities transactions and investment income: Securities transactions are
recorded as of the trade date. Realized gains and losses from securities
transactions are recorded on the identified cost basis. Dividend income is
recorded on the ex-dividend date. Interest income is recorded on the accrual
basis (primarily from accretion of U.S. Treasury Notes.)
 
Dividends and distributions to shareholders: Dividends from net investment
income of the Fund and distributions of net realized capital gains of the 
Fund,
if any, will be distributed annually after the close of the fiscal year in 
which
they are earned. In addition, in order to avoid the application of a 4%
nondeductible excise tax on certain undistributed amounts of ordinary income 
and
capital gains, the Fund may make an additional distribution of any 
undistributed
ordinary income or capital gains shortly before December 31st of each year, 
and
expects to pay any other dividends and distributions as are necessary to avoid
the application of this tax. Income distributions and capital gain 
distributions
are determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. These differences are primarily due 
to
differing treatments of income and gains on various investment securities held
by the Fund, timing differences and differing characterization of 
distributions
made by the Fund as a whole.
 
Federal income taxes: It is the Fund's policy to comply with the requirements 
of
the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and to distribute substantially all of its taxable income
to its shareholders. Therefore, no Federal income tax provision is required.

The Trust has entered into an investment advisory agreement (the "Advisory
Agreement") with Smith Barney Asset Management, a division of Smith, Barney
Advisers, Inc. ("SBA") which is controlled by Smith Barney Holdings Inc.

state securities regulations. All such costs are being amortized on the
straight-line method over a period of five years from the commencement of
operations of the Fund. In the event that any of the initial shares of the 
Fund
are redeemed during such amortization period, the Fund will be reimbursed for
any unamortized costs in the same proportion as the number of shares redeemed
bears to the number of initial shares outstanding at the time of redemption.
 
6.  LINE OF CREDIT
 
The Fund and several affiliated entities participate in a $50 million line of
credit provided by Continental Bank N.A. under an Amended and Restated Line of
Credit Agreement (the "Agreement") dated April 30, 1992, primarily for 
temporary
or emergency purposes, including the meeting of redemption requests that
otherwise might require the untimely disposition of securities. Under this
Agreement, the Fund may borrow up to the lesser of $25 million or 20% of its 
net
assets. Interest is payable either at the bank's Money Market Rate or the 
London
Interbank Offered Rate (LIBOR) plus .375% on an annualized basis. The Fund and
the other affiliated entities are charged an aggregate commitment fee of
$125,000 which is allocated equally among each of the participants. The
Agreement requires, among other provisions, each participating fund to 
maintain
a ratio of net assets (not including funds borrowed pursuant to the Agreement)
to aggregate amount of indebtedness pursuant to the Agreement of no less than 
5
to 1. During the six months ended May 31, 1994, the Fund had an average
outstanding daily balance of $95,055 with interest rates ranging from 3.31% to
3.88%. Interest expense totalled $2,699 for the six months ended May 31, 1994.
At May 31, 1994, the Fund had no outstanding borrowings under this Agreement.

OUR APPROACH TO MUTUAL FUND INVESTING
- - ------------------------------------------------------------------------------
- - --
 
1. PERSONAL SERVICE
 
The Smith Barney Financial Consultant ("FC") is highly trained and deeply
committed to client service. Your FC works with you to establish a 
relationship
based on one-to-one communication and the highest standards of quality.
 
2. ANALYZING YOUR NEEDS
 
Defining your needs and establishing specific goals is the first step toward 
any
successful investment program. The Smith Barney Strategic Asset Allocator -- a
sophisticated financial planning tool -- can help you and your FC evaluate 
your
resources and objectives. This groundwork then becomes the basis for a 
strategy
designed specifically for you. Your FC can use the Strategic Asset Allocator 
on
a periodic basis to ensure that your investment strategy is keeping pace with
your changing needs and goals.
 
3. A UNIQUE MUTUAL FUND INVESTMENT PROGRAM
 
Your Smith Barney FC offers a number of mutual fund assessment tools that are
unmatched in the financial services industry. Smith Barney FCs have access to 
a
proprietary mutual fund research database that provides information at their
fingertips on more than 2,100 funds. In addition, working with another
proprietary system known as the Mutual Fund Evaluation Service, your FC can 
help
guide you through the complex mutual fund maze. Specifically, the Evaluation
Service can provide a clear picture of the past performance of mutual funds 
you
currently own. Presented in both graphic and numerical form, this illustration
provides a wealth of easily understood data on more than 2,100 funds. This
complimentary service allows you to judge whether your mutual fund has helped
meet your investment needs.
 
4. LOOKING AHEAD
 
Selecting a mutual fund should not be a one-event process that ends with the
purchase of shares. You can count on the expertise of your FC as he or she
continues to monitor and evaluate your funds, to suggest new strategies and to
listen. That, in our opinion, is how to use mutual funds to help achieve your
financial goals.

PRINCIPAL RETURN FUND
Zeros Plus Emerging Growth Series 2000

 
             DEAR SHAREHOLDER:

For the first half of the fiscal year ended May 31, 1994, the net asset value
of the Fund declined 4.93%. This compared with a gain of 0.24% for the 
Standard
& Poors Daily Price Index of 500 Common Stocks (S&P 500). The Value Line 
Index,
which represents a better measure of performance for the kinds of securities
held in the Fund, declined 1.2% in the same six month period. These
unmanaged indices track the movement of common stock prices. Following a 
strong
six month period ended November 31, 1993, growth stocks as well as Treasury
securities suffered a sharp correction. Approximately 60% of the net assets of
the Fund are invested in Zero Coupon U.S. Treasury Notes maturing in the year
2000 with the balance invested in growth stocks.
 
For the first time in five years, the Federal Reserve Board changed its
monetary policy from one of accommodation, in which reserves were created 
quite
abundantly and interest rates kept at historically low levels, to one of
neutrality, where the Federal Funds rate so far has been increased 125 basis
points and the discount rate 50 basis points. From the low point reached in
1993, the yield on the 30 year Treasury Bond increased from 5.74% to a recent
range of 7.25% to 7.55%. This sharp increase in long-term interest rates not
only contributed to a decline in the value of Treasury Notes but in the 
overall
valuation of the stock market. Remember though, that at maturity, our Notes
will be priced at $100 compared to their recent price of $68 regardless of
monetary policy.
 
Several factors contributed to the disproportionate rise in long rates 
compared
to short-term interest rates a) fears that the strengthening economy would 
lead
to a pickup in the rate of inflation, b) the liquidation of leveraged bond
positions which were put on with the expectation that interest rates would
continue falling, c) concern over a weak U.S. dollar and its 
potentia**********************************************************************

******************************************************************************

****************************************************s. In addition, the 
Clinton Administration's tax
hike will also act as a drag on consumer spending. If in fact, this scenario
unfolds, it would be considered quite positive for the credit markets and may
eventually lead to a decline in the level of interest rates. Stock prices
because of their linkage to bond prices would also react favorably to a 
decline
in interest rates, even if it would mean a somewhat lower level of profits 
from
a slowing in business.

We continue to be quite optimistic about the outlook for top-tier 
biotechnology,
technology and telecommunications companies. The latter group appears
particularly attractive with the explosion of wireless communications and
significant capital expenditures being undertaken by cable and telephone
companies. C-COR Electronics, Inc. and California Microwave, Inc. have seen a
surge in orders in recent quarters. Genentech, our largest shareholding
continues to make great progress not only in the clinic, but in achieving 
record
sales and earnings.
 
In the Fund, we try to own companies whose sales and earnings depend more on
innovation and leadership positions in emerging industries rather than on the
vicissitudes of the economy. Price/Earnings multiples on growth stocks are
influenced by the level of interest rates and the expected growth rate in
earnings for the particular company. While we have no control over interest
rates, we try to buy companies able to grow significantly faster than the
average U.S. corporation. If our companies achieve strong, consistent earnings
growth, their stock prices should appreciate at a rate approximating their
earnings growth rates, provided there are no further increases in interest
rates. While the markets have indeed been turbulent, we fully expect our 
stocks
to provide a strong return over the long term. When combined with the 
guaranteed
appreciation of the Zeros, we hope to offer you a rewarding return on your
investment.
 
We value your trust and support and will continue to strive to provide you 
with
the highest level of investment management.
 
Sincerely,
 
/s/ Heath B. McLendon                  /s/ Richard A. Freeman

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.  SIGNIFICANT ACCOUNTING POLICIES
 
Smith Barney Shearson Principal Return Fund (the "Trust") was organized on
October 18, 1988, under the laws of the Commonwealth of Massachusetts as a
"Massachusetts business trust." The Trust is a diversified, open-end 
management
investment company registered with the Securities and Exchange Commission 
under
the Investment Company Act of 1940, as amended. The Trust consists of four
series, Zeros and Appreciation Series 1996, which commenced operations on
January 16, 1989, Zeros and Appreciation Series 1998 which commenced 
operations
on January 25, 1991, Zeros Plus Emerging Growth Series 2000 which commenced
operations on August 30, 1991 and Zeros Plus European Equities Series 1999,
which has not yet commenced operations. Zeros Plus Emerging Growth Series 2000
(the "Fund") expects to terminate operations on February 28, 2000. The 
following
is a summary of significant accounting policies consistently followed by the
Fund in the preparation of its financial statements.
 
Portfolio valuation: Listed securities traded on a national securities 
exchange
are valued at the last reported sales price; securities traded in the
over-the-counter market and listed securities for which no sale was reported 
are
valued at the bid price or, in the absence of a recent bid price, at the bid
equivalent as obtained from one or more of the major market makers in the
securities. Investments in U.S. government securities (other than short-term
securities) are valued at the quoted bid price in the over-the-counter market.
Short-term investments that mature in 60 days or less are valued at amortized
cost whenever the Board of Trustees determines that amortized cost reflects 
the
fair value of those investments. Investments in securities for which market
quotations are not available are valued at fair value as determined in good
faith by the Board of Trustees.
 
Repurchase agreements: The Fund may engage in repurchase agreement 
transactions.
Under the terms of a typical repurchase agreement, the Fund takes possession 
of
an underlying debt obligation subject to an obligation of the seller to
repurchase, and the Fund to resell, the obligation at an agreed-upon price and
time, thereby determining the yield during the Fund's holding period. This
arrangement results in a fixed rate of return that is not subject to market
fluctuations during the Fund's holding period. The value of the collateral 
held
by the Fund is at least equal at all times to the total amount of the 
repurchase
obligations, including interest. In the event of counterparty default, the 
Fund
has the right to use the collateral to offset losses incurred. There is
potential loss to the Fund in the event that the Fund is

delayed or prevented from exercising its rights to dispose of the collateral
securities, including the risk of a possible decline in the value of the
underlying securities during the period while the Fund seeks to assert its
rights. The Fund's investment adviser, acting under the supervision of the
Trust's Board of Trustees, reviews the value of the collateral and the
creditworthiness of those banks and dealers with which the Fund enters into
repurchase agreements to evaluate potential risks.
 
Securities transactions and investment income: Securities transactions are
recorded as of the trade date. Realized gains and losses from securities
transactions are recorded on the identified cost basis. Dividend income is
recorded on the ex-dividend date. Interest income is recorded on the accrual
basis.
 
Dividends and distributions to shareholders: Dividends from net investment
income of the Fund and distributions of net realized capital gains of the 
Fund,
if any, will be distributed annually after the close of the fiscal year in 
which
they are earned. In addition, in order to avoid the application of a 4%
nondeductible excise tax on certain undistributed amounts of ordinary income 
and
capital gains, the Fund may make an additional distribution of any 
undistributed
ordinary income or capital gains shortly before December 31st of each year, 
and
expects to pay any other dividends and distributions as are necessary to avoid
the application of this tax. Income distributions and capital gain 
distributions
are determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. These differences are primarily due 
to
differing treatments of income and gains on various investment securities held
by the Fund, timing differences and differing characterization of 
distributions
made by the Fund as a whole.
 
Federal income taxes: It is the Fund's policy to comply with the requirements 
of
the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and to distribute substantially all of its taxable income
to its shareholders. Therefore, no Federal income tax provision is required.
 
2.   INVESTMENT ADVISORY FEE, ADMINISTRATION FEE
     AND OTHER TRANSACTIONS
 
The Trust has entered into an investment advisory agreement (the "Advisory
Agreement") with Smith Barney Asset Management, a division of Smith, Barney
Advisers, Inc. ("SBA"), which is controlled by Smith Barney Holdings Inc.
("Holdings"). Holdings is a wholly owned subsidiary of The Travelers Inc.

the Advisory Agreement, the Fund pays a monthly fee at the annual rate of .40%
of the value of its average daily net assets.
 
Prior to April 21, 1994, the Trust was party to an administration agreement 
with
The Boston Company Advisors, Inc. ("Boston Advisors"), an indirect wholly 
owned
subsidiary of Mellon Bank Corporation ("Mellon"). Under this agreement, the 
Fund
paid a monthly fee at the annual rate of .20% of the value of its average 
daily
net assets.
 
As of the close of business on April 21, 1994, SBA succeeded Boston Advisors 
as
the Fund's administrator. The new administration agreement contains
substantially the same terms and conditions, including the level of fees, as 
the
predecessor agreement.
 
As of the close of business on April 21, 1994, the Fund has also entered into 
a
sub-administration agreement (the "Sub-Administration Agreement") with Boston
Advisors. Under the Sub-Administration Agreement, Boston Advisors is paid a
portion of the fee paid by the Fund to SBA at a rate agreed upon from time to
time between SBA and Boston Advisors.
 
Smith Barney Inc. ("Smith Barney") serves as shareholder servicing agent and 
is
paid an annual fee at the rate of .25% of the value of the Fund's average 
daily
net assets for certain activities not provided by the Fund's transfer agent.
 
No officer, director or employee of Smith Barney or any parent or subsidiary 
of
Smith Barney receives any compensation from the Trust for serving as a Trustee
or officer of the Trust. The Trust pays each Trustee who is not an officer,
director or employee of Smith Barney or any of its affiliates $2,000 per annum
plus $500 per meeting attended and reimburses each Trustee for travel and
out-of-pocket expenses.
 
Boston Safe Deposit and Trust Company, an indirect wholly owned subsidiary of
Mellon, serves as the Trust's custodian. The Shareholder Services Group, Inc., 
a
subsidiary of First Data Corporation, serves as the Trust's transfer agent.
 
3.   PURCHASES AND SALES OF SECURITIES
 
Cost of purchases and proceeds from sales of securities, excluding U.S.
government securities and short-term investments, aggregated $765,075 and

Credit Agreement (the "Agreement") dated April 30, 1992, primarily for 
temporary
or emergency purposes, including the meeting of redemption requests that
otherwise might require the untimely disposition of securities. Under this
Agreement, the Fund may borrow up to the lesser of $25 million or 20% of its 
net
assets. Interest is payable either at the bank's Money Market Rate or the 
London
Interbank Offered Rate (LIBOR) plus .375% on an annualized basis. The Fund and
the other affiliated entities are charged an aggregate commitment fee of

to aggregate amount of indebtedness pursuant to the Agreement of no less than 
5
to 1. During the six months ended May 31, 1994, the Fund had an average
outstanding daily balance of $67,033 with interest rates ranging from 3.31% to
4.81%. Interest expense totalled $1,973 for the six months ended May 31, 1994.

you

provides a wealth of easily understood data on more than 2,100 funds. This
complimentary service allows you to judge whether your mutual fund has helped

continues to monitor and evaluate your funds, to suggest new strategies and to
