The idiosyncratic volatility anomaly, as first documented in Ang, Hodrick, Xing, and Zhang (2006), has received considerable attention in the literature. In this paper, we examine the pervasiveness of the anomaly in various stock samples and provide evidence towards distinguishing potential...

This paper investigates mispricing (specifically limits to arbitrage) as an alternative to the risk-based explanation of the globalization premium documented by Barrot et al. (2019). We document that the globalization premium is positively correlated with measures of limits to arbitrage. We...

Earnings announcements present a clear risk to investors and, under rational asset pricing theory, such risk should be consistently priced in stocks. However, we find that stocks with high earnings announcement risk earn significantly higher returns only during months when firms have earnings or...

This paper specifies a multivariate stochastic volatility (SV) model for the S&P500 index and spot interest rate processes. We first estimate the multivariate SV model via the efficient method of moments (EMM) technique based on observations of underlying state variables, and then investigate...

In this paper, we show that conditions derived under the CAPM ensure only weak exogeneity in a linear regression setting. Since strong exogeneity is not guaranteed, the OLS estimator of CAPM beta is only consistent but not necessarily unbiased. We provide empirical evidence that individual daily...
