Where are the smart investors? New evidence of the smart money effect

Previous research debates whether investors are smart enough to invest in funds that subsequently outperform. This paper documents a robust smart money effect among top-performing small fund investors, even after controlling for the momentum factor. I further explore the reason for the smart money effect and find that such outperformance comes from the market-timing ability of smart investors. Market-timing ability distinguishes smart investors from investors who naively chase the winners.
