This paper shows that the stylized fact of average mutual fund underperformance documented in the literature stems from expansion periods when funds have statistically significant negative risk-adjusted performance and not recession periods when risk-adjusted fund performance is positive. These...

The empirical literature of stock market predictability mainly suffers from model uncertainty and parameter instability. To meet this challenge, we propose a novel approach that combines the documented merits of diffusion indices, regime-switching models, and forecast combination to predict the...

Firm size is an essential factor in examining the relation between returns and idiosyncratic volatilities. This paper documents that, when the idiosyncratic volatility is specified by firm size, the size-portfolio idiosyncratic volatility is statistically significant in explaining the future...

In this paper, we review the most common specifications of discrete-time stochastic volatility (SV) models and illustrate the major principles of corresponding Markov Chain Monte Carlo (MCMC) based statistical inference. We provide a hands-on ap proach which is easily implemented in empirical...
