Abstract:
To investigate the performance evaluation method of fixed income fund managers in Thailand. Bootstraping method is implemented to test government and corporate bond picking skill of these fund managers and also to further test the persistent of fund performance. This study uses samples based on weekly NAV return data of 108 fixed income funds from 14 asset management companies, which are gathered from Association of Investment Management Companies (AIMC), and weekly bond return data from The Thai Bond Market Association (ThaiBMA) between January 2002 and December 2004. The result of the study is that most of funds could get abnormal return higher than the benchmark porfolio by long-term bond holding strategy, but investing in all kinds of bond in bond market gave most of funds the lower abnormal return than benchmark portfolio. When applying bootstrapping method to test fund managers' bond picking skill, the study shows that some top rank fund managers do not have only bond picking skill, but also may have luck in investing to create high abnormal return. In the same way, bottom rank fund managers do not only lack of skill to create higher abnormal return than market, but also probably caused by their bad luck. In case of performance persistent test, fund performances from investment in bond market persist only in top rank fund portfolios. On the other hand, persistent of fund performances from investment in long term bonds exist in most of funds except in top and bottom rank fund portfolios in conclusion, the past performance of fixed income fund manager can be used as an indicator for investors to decide which fund that should be invested.
