We document lead-lag effects in stock returns between co-headquartered firms operating in different sectors. Such geographic lead-lags yield risk-adjusted returns of 5-6% per year, about half that observed for industry lead-lag effects. However, while industry lead-lag effects are strongest...

I compare the timing of information acquisition among institutional investors and sell-side analysts. I find that hedge funds are unique: they anticipate analyst reports, and then reverse their positions after analysts publish reports. These trends are strongest for hedge funds and analysts most...

The existing replication policies at top finance journals are far weaker than the policies at top economics journals. This paper explores both the costs and benefits of having a stronger replication policy in the context of my failed 2010 initiative to develop a unified policy across all top...

Theoretical models imply fund size and performance should be negatively linked. However, empiricists have failed to uncover consistent support for this negative relation. Using a new econometric framework which includes fund-specific sensitivities to decreasing returns to scale, we find a both...

Using the number of Robinhood users holding a firm’s shares, I examine how novice retail investors respond to earnings announcements and the implications of their responses for the price-earnings relation. I do not find evidence of informed trading among these investors. Changes in their...

I compare the timing of information acquisition among institutional investors and sell-side analysts, and I show that hedge fund trades predict the direction of subsequent analyst ratings change reports while other investors' trades do not. In addition, hedge funds reverse trades after analyst...

An enhanced option pricing framework that makes use of both continuous and discontinuous time paths based on a geometric Brownian motion and Poisson-driven jump processes respectively is performed in order to better fit with real-observed stock price paths while maintaining the analytical...

This chapter reviews short selling practices in emerging markets and market performances during the global financial crisis. In contrast to developed markets, many emerging countries do not permit short selling, which can pose severe limitations on market liquidity. We compare market volatility,...
