Mutual fund managers do not have full freedom in choosing investment strategies - they are limited both by the laws and by investment declarations of the funds. Investment strategy cannot be fully changed even in financial crisis but it only can be corrected. This fact could not be characterized as a disadvantage because different types of funds are efficient in different time even during the same economic recession. Mutual fund manager should rationally invest funds of their clients: it is better to keep the maximum possible part of the portfolio in cash and instruments with fixed income on the declining market and it is better to keep shares on the rising market. However the choice of bonds also as the choice of shares should pay respect for the features of these instruments during unfavorable economic conditions. Russian mutual fund management differs from fund management in other countries as in stable economic situation so in the circumstances of financial crisis.
