We examine the short-run relationship between stock-return volatility and daily equity trading by several investor groups in the Korean Stock Exchange. We also investigate whether trade characteristics and trading styles can explain the potential distinct volatility effects of these investor...

We examine the impact of tail risk on the return dynamics of size, book-to-market ratio, momentum, and idiosyncratic volatility sorted portfolios. Our time-series analyses document significant portfolio return exposures to aggregate tail risk. In particular, portfolios that contain small, value,...

This paper investigates empirically whether uncertainty about equity market volatility can explain hedge fund performance both in the cross section and over time. We measure uncertainty via volatility of aggregate volatility (VOV) and construct an investable version through returns on lookback...

Following seminal works of Knight (1921) and Ellsberg (1961), we distinguish uncertainty from risk and examine the impact of aggregate uncertainty on return dynamics of size and book-to-market ratio sorted portfolios. Using VVIX as a proxy for aggregate uncertainty and controlling for market...

Recent empirical studies show that statistical forecasts of a stock's return skewness negatively price stocks, apparently consistent with recent theoretical studies. While the theoretical studies, however, focus on skewness over long return horizons, the empirical studies focus on skewness over...

We propose a volatility-based capital asset pricing model (V-CAPM) in which asset betas change discretely with respect to changes in investors' expectations regarding near-term aggregate volatility. Using a novel measure to proxy uncertainty about expected changes in aggregate volatility, i.e....

This paper documents that systematic volatility risk is an important factor that drives the value premium observed in the French stock market. Using returns on at-the-money straddles written on the CAC 40 index as a proxy for systematic volatility risk, I document significant differences between...

It is well documented that stock returns have different sensitivities to changes in aggregate volatility, however less is known about their sensitivity to market jump risk. By using Samp;P 500 crash-neutral at-the-money straddle and out-of-money put returns as proxies for aggregate volatility...

This article examines agents' consumption-investment problem in a multi-period pure exchange economy where agents are constrained with the short-sale of state-dependent risky contingent claims. In equilibrum, agents hold options written on aggregate consumption in their optimal portfolios....

Using a relatively common phenomenon of eponymy in the hedge fund industry where funds are named after their founder-managers, we examine if eponymy is associated with skilled managers signaling their ability. Our results suggest that eponymous fund managers are neither necessarily skilled nor...
