Persistence & Survivorship Bias in Mutual Funds: An Indian Experience. A Study on Performance of Indian Mutual Funds with special focus on Persistence and Survivor-ship Bias

      Аннотация: This study utilizes few selected performance evaluation techniques on a sample of 36 Indian mutual fund schemes, over the period of January 2001 to September 2009. The broad based S&P CNX NIFTY is used in the study as a benchmark. The results concluded that these 36 mutual fund managers were on average not able to predict security prices well enough to outperform a buy-the-market-and-hold policy. There was very little evidence of any individual fund being able to do significantly better than which was expected from random chance. On the other hand, no evidence of curvature of the characteristic lines, indicating superior timing skill, is found for any of the funds. In addition, the study offers little evidence of persistence in either the stock selection ability or the timing ability of the fund managers. Mutual fund attrition can create problems for a researcher because funds disappear due to presumably poor performance resulting into bias in research outcome. In this study we also revisit the mutual fund performance, including the disappeared mutual fund schemes during sample period. By tracking disappeared funds, the study does not find any evidence of survivorship bias.
