We argue that arbitrageurs will strategically limit their initial investment in an arbitrage opportunity in anticipation of further mispricing caused by the deepening of noise traders' misperceptions. Such ‘noise momentum' is an important determinant of the overall arbitrage process. We design...

In this paper, we study mutual fund performance in terms of timing ability with daily data from 1998 to 2009. A novel timing model is proposed by incorporating the regime-switching framework into the Treynor and Mazuy (1966) model. The volatility follows a generalized autoregressive conditional...

Employing a broad sample of US firms over the period 1962 to 2009, we provide evidence of a liquidity risk impact on the fundamental earnings-returns relation. Specifically, we document that current liquidity risk has a positive moderating effect on the relation between current returns and next...

We employ a characteristic-based model to decompose total analyst coverage into abnormal and expected components and show that abnormal coverage contains valuable information about individual firm ex-ante crash risk (proxied by implied volatility smirk from options data). Specifically, one...

This article analyzes the impact of movements in the Australian dollar/Japanese yen (AUDJPY) and the Australian dollar/US dollar (AUDUSD) exchange rates on the returns of the Australian equities market. Specifically, this paper investigates the nature of exchange rate exposure across increasing...

We show that option-implied jump tail risk estimated prior to earnings announcements strongly predicts post-earnings risk-adjusted abnormal stock returns. The predictive power of implied jump tail risk is particularly strong on extreme abnormal stock returns whose absolute values exceed 10%. The...

We argue that a higher sensitivity to aggregate market-wide liquidity shocks (i.e. a higher liquidity risk) implies a tendency for a stock's price to converge to fundamentals. We test this intuition within the framework of the earnings-returns relation. We find a positive liquidity risk effect...
