With the rapid growth of mutual funds, increasing emphasis has been placed on the question of proper performance evaluation. However, the identification of superior performing funds remains a controversial topic, which evens the academic literature after several decades of debate has been unable to resolve. Using a sample free of survivor bias, I perform a comprehensive analysis of the mutual fund. Firstly, I address the question of proper measures and benchmarks. Different measures of performance are compared and benchmark sensitivity is analyzed. Then, this study provides an analysis of the interrelationship and impact of a thorough list of fund-specific characteristics on fund performance. The purpose of this study is to identify specific factors linked to fund performance. Finally, after controlling for survivorship bias and fund-specific factors, this study also provides an analysis of the persistence of mutual funds.
