— September 9, 2017
Excerpt from Barron's -- "Benchmark deviants can swing high—or low. Funds with high active share—the percentage of holdings that differ from the fund's benchmark index—tend to outperform, so long as managers pick the right securities. Yakov Amihud, a professor of finance at New York University's Leonard N. Stern School of Business, says his research shows that every 10% deviation from an index affects annual return by eight percentage points."
