"Return Horizon and Mutual Fund Performance"

Event details of CIFRA UvA Finance Seminars: Hendrik Bessembinder (Arizona State University)
Date 16 September 2021
Time 18:00 -19:15

Introduction

Measures of investment performance depend on the horizon over which returns are assessed.  While 47% of U.S. equity mutual fund returns exceed matched-month SPY ETF returns, only 29% of the funds outperform the SPY in terms of compound returns over the full 1991-2018 sample period.  More important, alpha, the canonical measure of mean return after allowing for systematic (beta) risk, depends on return horizon, because beta depends on horizon.  Compared to a benchmark of 41% estimated in monthly returns, the percentage of mutual funds with positive alpha estimates against the SPY decreases to 21% (increases to 46%) at the decade return horizon for funds with high (low) estimated monthly market betas.  Alphas estimated from short-horizon (e.g. monthly) returns may be uninformative or even misleading regarding fund performance for investors with longer horizons.*
