Abstract: This study explores three major issues in mutual fund portfolio management in one of the emerging markets - Thailand. The first issue is to examine mutual fund managers' ability to time market coskewness by testing whether fund managers shift portfolio exposure when market coskewness changes which could be observed from changing in beta coefficient. The second issue is whether market coskeweness helps the mutual fund managers quest for alpha (superior) portfolio return. The third issue is to examine whether mutual funds managers' behaviours could be explained by the structure between bank and mutual fund relationship. Based on the analysis of 332 unique funds between January 2000 and November 2017, the results demonstrate that the good performing fund managers adjust their portfolio beta basing on changing in market coskewness. Outperform fund managers increase their portfolios' beta by 8.88% more than that of bottom performing fund managers. Besides, we find that both outperformed bank-related and non-bank-related mutual fund managers demonstrate an ability to time market coskewness. However, we find that non-bank-related mutual fund outperform bank-related mutual funds which support the conflict of interest hypothesis.

Keywords: coskewness; market timing; skewness; affiliated fund; bank-related fund; mutual fund; higher moment risk; Thailand.
