|August 2013||Alpha and Performance Measurement: The Effects of Investor Disagreement and Heterogeneity|
with Wayne E. Ferson: w19349
The literature has not unambiguously established that a positive alpha, as traditionally measured, means that an investor would want to buy a fund. However, when alpha is defined using the client's marginal utility function, a client faced with a positive alpha would generally want to buy. When markets are incomplete performance measurement is inherently investor specific, and investors will disagree about the attractiveness of a given fund. We provide empirical bounds on the expected disagreement with a traditional alpha and study the cross sectional effects of disagreement and investor heterogeneity on the flow response to past fund alphas. The effects are both economically and statistically significant.
