Fleeting Alpha: Evidence from SPIVA and Persistence Scorecards Can past winners persist across longer time horizons, market caps, and investment styles?
BY Aye Soe

The phrase “past performance is no guarantee of future results” (or some variation thereof) can be found in most funds’ literature, and for good reason: a wealth of studies show a lack of long-term performance persistence among actively managed mutual funds. However, many investors appear to believe that winners persist: past performance and related metrics remain important factors in manager selection.



Since 2002, S&P Dow Jones Indices has published the SPIVA® U.S. Scorecard, measuring the percentage of active managers that beat their benchmarks across various equity and fixed income categories. Its sister report, the Persistence Scorecard, shows the likelihood that a top quartile manager maintains its status in subsequent periods.



By marrying the two reports, this paper studies the degree to which outperforming funds from one period continue to beat their benchmarks thereafter. Specifically, we first identify funds that beat their benchmarks, based on three-year annualized returns, net-of-fees. We then examine whether these funds (the “winners”) can continue to outperform during each of the next three one-year periods.



Our results show that among equity funds that beat their benchmarks over the three-year period ending September 30, 2015, there was typically negligible performance persistence among domestic and international equity categories beyond the one-year horizon. In other words, past performance did not typically help identify superior performing managers in advance.
