We study the behavior of a mutual fund manager in a discrete‐time model, in which new investors may choose to invest in the fund after the fund manager has made trading decisions. We show that under certain conditions the fund manager may choose to buy overvalued assets at the expense of the investors in order to attract new investments, who would otherwise not invest in the fund. This can potentially lead to higher risky asset prices and a higher‐than‐optimal proportion of investment in risky assets in the active fund management industry.
