Another Look at Mutual FundTournaments

Published online by Cambridge University Press:  06 April 2009

Abstract

Daily retutns are used to examine how mutual fundsactively alter the risk of their portfolios inresponse to past performance. Compared to monthlydata, daily returns produce much more efficientestimates of fund volatility, which give vastlydifferent inferences about the behavior of fundmanagers. In particular, monthly results consistentwith under-performers increasing their risk relativeto better performing funds disappear with dailydata. The differences in the monthly and dailyresults arise from biases in the monthly volatilityestimates attributable to daily returnautocorrelation.
