Abstract: In a continuous-time framework, we establish an optimal dynamic portfolio strategy for a loss-averse fund manager facing performance-induced fund flows. Using the martingale approach, we derive closed-form solutions to both the optimal terminal value and optimal dynamic strategy of the fund under management. The model shows that the loss-averse manager strives to earn high returns in good market conditions at the risk of losing all investments at the terminal date in bad market conditions. The prospect of higher fund inflows induced by superior performance motivates fund managers to take more aggressive investment strategies, increasing the fund's risk exposure, whereas the prospect of fund outflows due to underperformance has no impact on the fund manager's investment decision. While the prospect of higher fund inflows increases dynamic optimal wealth as well as optimal terminal wealth in good market conditions, in bad market conditions, it reduces dynamic optimal wealth and results in a higher chance of a complete loss at the terminal date. Finally, a manager with a higher degree of loss aversion tends to take a conservative investment strategy with a lower risk exposure especially in bad market conditions, leading to a lower dynamic and terminal wealth in good market conditions and also a lower chance of a complete loss in bad market conditions.
