This paper investigates the performance of option investments across different stocks by computing monthly returns on at-the-money straddles on individual equities. It finds that options with high historical returns continue to significantly outperform options with low historical returns over...

We analyze a discrete-time analog of Fershtman and Kamien's (1987) continuous-time duopoly model. As price adjustment becomes infinitely fast, Fershtman and Kamien found that their closed-loop equilibrium remains distinct from the static Cournot equilibrium. Yet, in our discrete-time model, the...

We find predictable patterns in stock returns. Stocks whose relative returns are high in a given half-hour interval today exhibit similar outperformance in the same half-hour period on subsequent days. The effect is stronger at the beginning and end of the trading day. These results suggest that...

This paper studies seasonal predictability in the cross section of international stock returns. Stocks that outperform the domestic market in a particular month continue to outperform the domestic market in that same calendar month for up to 5 years. The pattern appears in Canada, Japan, and 12...

Motivated by the literature on investment flows and optimal trading, we examine intraday predictability in the cross-section of stock returns. We find a striking pattern of return continuation at half-hour intervals that are exact multiples of a trading day, and this effect lasts for at least 40...

This paper explores the effect of extreme events or big jumps downwards and upwards on the jump‐diffusion option pricing model of Merton (1976). It starts by obtaining a special case of the jump‐diffusion model where there is a positive probability of a big jump downwards. Then, it obtains a...
