Among high active share portfolios—whose holdings differ substantially from their benchmark—only those with patient investment strategies (with holding durations of over two years) on average outperform, over 2% per year. Funds trading frequently generally underperform, including those with high active share. Among patient funds, separating closet index from high active share funds matters, as low active share funds on average underperform even with patient strategies. Our results suggest that U.S. equity markets provide opportunities for longer-term active managers, perhaps because of the limited arbitrage capital devoted to patient and active investment strategies.

This paper investigates the impact of unconventional monetary policy on firm financial constraints using the maturity extension program (MEP). Consistent with bond market segmentation and limits to arbitrage, around the MEP's announcement, stock prices rose for those firms more dependent on longer-term debt. These firms also issued more long-term debt during the MEP and expanded employment and investment. There is also evidence of “reach for yield” behavior, as the demand for riskier corporate debt also increased. Our results suggest that unconventional monetary policy might have relaxed financial constraints for some firms by inducing gap-filling behavior and affecting bond market risk premia

We examine institutional demand prior to well-known stock return anomalies and find that institutions have a strong tendency to buy stocks classified as overvalued (short leg of anomaly), and that these stocks have particularly negative ex post abnormal returns. Our results differ from numerous studies documenting a positive relation between institutional demand and future returns. We trace the difference to measurement horizon. We too find a positive relation at a quarterly horizon. However, the relation turns strongly negative at the one-year horizon used in anomaly studies. We consider several explanations for institutions’ tendency to trade contrary to anomaly prescriptions. Our evidence largely rules out explanations based on flow and limits-of-arbitrage, but is more consistent with agency-induced preferences for stock characteristics that relate to poor long-run performance
