Abstract
In this article we examine the risk factors that help explain long/short equity (LSE) mutual fund performance. We show that for most LSE mutual funds, 50%-80% of their returns can be explained using common factors such as capitalization, book-to-value ratio, dividend yield, and volatility. The explanatory strength of these factors is so strong that in most cases adding an option overlay using puts and calls (to mimic long and short positions) adds little or no explanatory value. We also show that while many funds have positive alpha, these alphas for the most part are not statistically significant, i.e., in reality they are not different than zero.
