Investment Style and Performance: Evidence for International Equity Mutual Funds

Abstract

In this paper we study the performance and performance persistence of international equity mutual funds with a focus on fund investment styles. Using a best-fit index methodology, we sort funds yearly based on the style dimensions of size and value/growth, as well as on regional categories (Europe, Pacific and emerging markets). In doing so, we find that (i) the performance of international funds clearly differs regarding style and regional categories, (ii) based on a five-factor alpha, most international style portfolios exhibit performance persistence, and (iii) top performing SMID-cap portfolios and top performing emerging market portfolios show significant and positive alphas. Moreover, using a conditional five-factor alpha as alternative ranking criteria further improves the prediction of future international fund performance.
