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...

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...

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 study the role of firm ambiguity on stock price reaction to earnings announcements. By using the firm's variance risk premium (VRP) prior to earnings news arrivals as a proxy for firm-level information ambiguity, we provide evidence that this “micro” form of ambiguity has a significant...

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 investigate the effects of S&P's sovereign re-ratings on the higher moments of equity market returns over recent financial crises. Using a set of intraday stock market index prices and sovereign credit ratings for a sample of 36 countries which experienced sovereign rating changes over the...

This paper tests whether and to what extent the value premium is induced by financial inflexibility risk. In this context, financial flexibility refers to the ability of a firm to alter investment expenditure to mitigate exogenous shocks, so as to generate a smooth dividend stream. Consistent...
