The performance of the Fund's four share classes varies because each has
different expenses. The Fund's total returns assume the reinvestment of all
distributions but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. See Performance Summary for standardized
performance and benchmark information.

MARKET CONDITIONS

For the six-month period ended March 31, 2007, global equity markets posted
positive returns. In the U.S., the benchmark S&P 500(R) Index returned 7.38
percent, including dividends, while internationally, the MSCI EAFE Index
returned 14.9 percent, including dividends.

While global economic conditions continued to be supportive of growth
expectations in excess of historical averages, the period under review might
best be characterized as potentially transitory. In the U.S., growth slowed as
both the consumer and industrial sectors adjusted to higher interest rates amid
more challenging housing and mortgage environments. At the same time, commodity
prices and labor costs increased slightly throughout the period, raising
concerns that record-level corporate profit margins could be squeezed from both
the "top" and "bottom" lines. In general, profit growth expectations declined
for a majority of sectors during the period under review.

Overseas, economic growth in both developed and emerging markets continued to
outpace expectations, as continental Europe, the United Kingdom, Russia, India,
China and Latin America generally exceeded growth expectations. Solid export
activity coupled with domestic demand tied to job security and purchasing power
helped drive these impressive trends. In effect, this acceleration outside the
U.S. helped many U.S. industries, as favorable currency exchange rates and years
of increased investment in international markets began to payoff in 2006, and
more recently, helped offset the slower pace of U.S. growth.

PERFORMANCE ANALYSIS

Morgan Stanley Institutional Strategies Fund outperformed the S&P 500(R) Index
and underperformed the Blended Index (a blend of 1/3 Russell 1000(R) Growth
Index, 1/3 Russell 1000(R) Value Index and 1/3 Morgan Stanley Capital
International [MSCI] EAFE Index) for the six months ended March 31, 2007,
assuming no deduction of applicable sales charges.

Morgan Stanley Institutional Strategies Fund invests equal dollar amounts in
three underlying Morgan Stanley Institutional Funds -- U.S. Large Cap Growth,
Large Cap Relative Value and Active International Allocation. For the six months
ended March 31, 2007, all three funds contributed positively to the overall
Fund's performance, with Active International Allocation returning 15.05
percent, U.S. Large Cap

 2


Growth returning 9.93 percent, and Large Cap Relative Value returning 6.91
percent.

In general, international markets provided superior returns to those available
in the U.S., with emerging markets (such as Brazil, China, India and Russia) and
continental Europe performing solidly. Within the Fund's U.S. exposure, growth
outperformed value as investors rotated into previously lagging sectors such as
information technology and health care.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

Data as of March 31, 2007. Subject to change daily. All percentages are as a

INVESTMENT STRATEGY

The Fund is a "fund of funds," meaning that it seeks to achieve its investment
objective by investing primarily in a combination of three portfolios of Morgan
Stanley Institutional Fund, Inc. ("Underlying Funds") on a fixed allocation
basis. The Fund makes equal allocations of its assets to the following three
Underlying Funds: Active International Allocation Portfolio ("Active
International Allocation"), Large Cap Relative Value Portfolio ("Large Cap
Relative Value") and U.S. Large Cap Growth Portfolio ("U.S. Large Cap Growth").
Investors may purchase the Underlying Funds directly only if they meet certain
investment minimums or other requirements set forth in each Underlying Fund's
prospectus. The Underlying Funds invest primarily in U.S. and foreign equity
securities. The investment policies of the Underlying Funds are described in the
Fund's prospectus. The investment results of the Underlying Funds will vary. As
a result, the percentage allocations to the Underlying Funds will be monitored
daily by the Fund's "Investment Adviser," Morgan Stanley Investment Advisors
Inc., and the Fund's allocations to the Underlying Funds will be rebalanced
whenever the actual allocations exceed plus or minus 5 percent of the
pre-determined fixed percentage allocation basis. Accordingly, it may be
necessary for the Fund to sell shares of an Underlying Fund that have
appreciated in value, in order to maintain the fixed percentage allocation among
the Underlying Funds.

                                                                               3

Performance data quoted represents past performance, which is no guarantee of
future results and current performance may be lower or higher than the figures
shown. For most recent month-end performance figures, please visit
www.morganstanley.com or speak with your Financial Advisor. Investment returns
and principal value will fluctuate and fund shares, when redeemed, may be worth
more or less than their original cost. The table does not reflect the deduction
of taxes that a shareholder would pay on fund distributions or the redemption of
fund shares. Performance for Class A, Class B, Class C, and Class D shares will
vary due to differences in sales charges and expenses. Returns for period less
than 1 year are not annualized.

*   The maximum front-end sales charge for Class A is 5.25%.

**  The maximum contingent deferred sales charge (CDSC) for Class B is 5.0%. The
    CDSC declines to 0% after six years.

+   The maximum contingent deferred sales charge for Class C is 1.0% for shares
    redeemed within one year of purchase.

++  Class D has no sales charge.

(1)  The Standard & Poor's 500(R) Index (S&P 500(R)) is a broad-based index, the
     performance of which is based on the performance of 500 widely-held common
     stocks chosen for market size, liquidity and industry group representation.
     The Index is unmanaged and its returns do not include any sales charges or
     fees. Such costs would lower performance. It is not possible to invest
     directly in an index.

(2)  The Blended Index is comprised of 1/3 Russell 1000(R) Growth Index
     (measures the performance of those companies in the Russell 1000(R) Index
     with higher price-to-book ratios and higher forecasted growth values), 1/3
     Russell 1000(R) Value Index (measures the performance of those companies in
     the Russell 1000(R) Index with lower price-to-book ratios and lower
     forecasted growth values) and 1/3 Morgan Stanley Capital International
     (MSCI) EAFE Index (measures the performance for a diverse range of global
     stock markets within Europe, Australasia, and the Far East). The Index is
     unmanaged and its returns do not include any sales charges or fees. Such
     costs would lower performance. It is not possible to invest directly in an
     index.

(3)  Figure shown assumes reinvestment of all distributions and does not reflect
     the deduction of any sales charges.

(4)  Figure shown assumes reinvestment of all distributions and the deduction of
     the maximum applicable sales charge. See the Fund's current prospectus for
     complete details on fees and sales charges.

                                                                               5


EXPENSE EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments and redemption fees;
and (2) ongoing costs, including distribution and service (12b-1) fees; and
other Fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/01/06 - 03/31/07.

ACTUAL EXPENSES


The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES


The second line of the table below provides information about hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing cost of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) and redemption fees. Therefore, the second line of the table is
useful in comparing ongoing costs, and will not help you determine the relative
total cost of owning different funds. In addition, if these transactional costs
were included, your costs would have been higher.

- ------------------

*  Expenses are equal to the Fund's annualized expense ratios of 0.56%, 1.39%,
   1.39% and 0.39% for Class A, Class B, Class C and Class D shares,
   respectively, multiplied by the average account value over the period,
   multiplied by 182/365 (to reflect the one-half year period). If the Fund had
   borne all of its expenses, the annualized expense ratios would have been
   15.49%, 16.32%, 16.32% and 15.32% for Class A, Class B, Class C and Class D
   shares, respectively.

Morgan Stanley Institutional Strategies Fund
NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2007 (UNAUDITED)

1. Organization and Accounting Policies

Morgan Stanley Institutional Strategies Fund (the "Fund") is registered under
the Investment Company Act of 1940, as amended (the "Act"), as a
non-diversified, open-end management investment company. The Fund will invest in
a combination of three portfolios of Morgan Stanley Institutional Fund, Inc.
(individually, an "Underlying Fund" and collectively, the "Underlying Funds") on
a fixed allocation basis. The Fund's investment objective is to seek capital
appreciation. The Fund was organized as a Massachusetts business trust on May 2,
2006 and commenced operations on August 28, 2006.

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 and 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 eighteen
months, 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 following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) Investments are valued at the net asset value
per share of each Underlying Fund determined as of the close of the New York
Stock Exchange on valuation date; and (2) 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.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. Repurchase Agreements -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Adviser, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, U.S. Treasury or federal agency obligations. The Fund may also invest
directly with institutions in repurchase agreements. The Fund's custodian
receives the collateral, which is marked-

                                                                              11

Morgan Stanley Institutional Strategies Fund
NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2007 (UNAUDITED) continued

to-market daily to determine that the value of the collateral does not decrease
below the repurchase price plus accrued interest.

D. 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.

E. Federal Income Tax Policy -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

F. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

G. Use of Estimates -- 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.

H. Offering Costs -- The Investment Adviser incurred offering costs on behalf of
the Fund in an amount of $98,000 which will be reimbursed by the Fund for the
full amount thereof. Such expenses were deferred and are being amortized on the
straight-line method over a period of approximately one year or less from the
commencement of operations.

2. Investment Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement, the Fund pays no investment
advisory fee. However, the Fund, through its investments in the Underlying
Funds, will pay its pro rata share of the advisory fees to the Investment
Adviser of the Underlying Funds.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays no administration fee. However, the Fund through its investments in the
Underlying Funds, will pay its pro rata share of the administration fee to the
Administrator of the Underlying Funds.

The Investment Adviser agreed to waive or reimburse all or a portion of the
Fund's other expenses such that the annualized actual total fund operating
expenses (exclusive of any indirect expenses from the Underlying Funds) does not
exceed 0.64%, 1.39%, 1.39% and 0.39% for Class A, Class B, Class C and Class D
shares respectively, until August 31, 2007. Thereafter, the fee waiver and/or
expense reimbursement can be terminated at any time. At March 31, 2007, included
in the

Morgan Stanley Institutional Strategies Fund
NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2007 (UNAUDITED) continued

Statements of Assets and Liabilities is a receivable from the Investment Adviser
an affiliate, which represents expense reimbursements due to the Fund.

3. Plan of Distribution

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Adviser and Administrator. 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 -- up to 0.25% of the average daily net assets of Class A shares; (ii) Class
B -- up to 1.0% of the average daily net assets of Class B shares; and (iii)
Class C -- up to 1.0% of the average daily net assets of Class C shares.

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 totaled $3,280 at
March 31, 2007

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 Morgan Stanley Financial Advisors and other authorized
financial representatives at the time of sale may be reimbursed in the
subsequent calendar year. For the six months ended March 31, 2007, the
distribution fee was accrued for Class A shares and Class C shares at the annual
rate of 0.17% and 1.0%, respectively.

The Distributor has informed the Fund that for the six months ended March 31,
2007, it received no contingent deferred sales charges from certain redemptions
of the Fund's Class A shares, Class B shares and Class C shares, respectively
and received no 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.

                                                                              13

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 ending March 31, 2007 aggregated
$394,851 and $51,065, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and
Distributor, is the Funds transfer agent.

The Fund has an unfunded Deferred Compensation Plan (the "Compensation Plan")
which allows each independent Trustee to defer payment of all, or a portion, of
the fees he or she receives for serving on the Board of Trustees. Each eligible
Trustee generally may elect to have the deferred amounts credited with a return
equal to the total return on one or more of the Morgan Stanley funds that are
offered as investment options under the Compensation Plan.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund.

6. Expense Offset

The expense offset represents a reduction of the fees and expenses for interest
earned on cash balances maintained by the Fund with the transfer agent.

7. Federal Income Tax Status

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 tax purposes are reported as distributions of paid-in-capital.

As of September 30, 2006, the Fund had temporary book/tax differences
attributable to capital loss deferrals on wash sales.

8. Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes -- an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006 and is to be
applied to all open tax years as of the effective date. The impact to the Fund's
inancial statements, if any is currently being assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

                                                                              15
