Five Facts About Beliefs and Portfolios

Perspective

The Replication Crisis That Wasn’t

Factor investing has long faced criticisms of data mining, and more recently faced another criticism – some backtests might never have been right to begin with. A growing body of mostly well-done papers examine these issues, generally concluding that factors have been disappointing since their “discovery.” We’ve long addressed these concerns through robust out-of-sample evidence and a compelling theory for why a factor should work. What we’ve lacked, until now, is a formal test. My colleagues’ new paper tests brilliantly, what we have argued, largely anecdotally, for years. Their results are rather startlingly (even to me) positive for the field in general.

Game On: Social Networks and Markets

This paper studies how echo-chamber effects and fake news can lead to disagreement and misinformation with effects on investors’ portfolios and market prices. It presents a model how an investment idea can propagate through a social network, generating a trading frenzy with high turnover, a bubble in the price, and high price volatility. The paper also presents empirical evidence on the dramatic events related to the GameStop stock in January 2021 and discusses broader economic implications.
