Abstract：
The performance of fund managers is one of key issue. The individual's preference and decision is influenced by his embedded social network. This paper investigates the impact of manager's social network attributes on his investment performance by setting up a social network with alumni and colleagues who works as fund managers of China Security Investment Fund in 2003-2010. The results indicate that by occupying a central network position, the performance of the fund manager can be upgraded. Mangers with abundant structural holes gain more profits than managers with fewer structural holes.
