SUPPLEMENT DATED OCTOBER 30, 2007 TO THE PROSPECTUS OF
MORGAN STANLEY FOCUS GROWTH FUND
Dated April 30, 2007 

The section of the Prospectus entitled ‘‘The Fund — Investment Objective’’ is hereby deleted and replaced with the following:  

Morgan Stanley Focus Growth Fund seeks long-term capital growth. 

*** 

The first sentence of the section of the Prospectus entitled ‘‘The Fund — Principal Investment Strategies’’ is hereby deleted and replaced with the following:  

The Fund normally invests at least 65% of its assets in a portfolio of common stocks (including depositary receipts). 

*** 

The following paragraph is hereby added as the ninth paragraph to the section of the Prospectus entitled ‘‘The Fund — Principal Risks’’:  

Non-Diversified Status.    The Fund is a ‘‘non-diversified’’ mutual fund and, as such, its investments are not required to meet certain diversification requirements under federal law. Compared with ‘‘diversified’’ funds, the Fund may invest a greater percentage of its assets in the securities of an individual corporation or governmental entity. Thus, the Fund’s assets may be concentrated in fewer securities than other funds. A decline in the value of those investments would cause the Fund’s overall value to decline to a greater degree.
