We study the term structure of variance (total risk), systematic and idiosyncratic risk. Consistent with the expectations hypothesis, we find that, for the entire market, the slope of the term structure of variance is mainly informative about the path of future variance. Thus, there is little...

Option-implied betas are a promising alternative to historical beta estimators, because they are inherently forward …-looking and can incorporate new information immediately and fully. Recently, different implied beta estimators have been developed … first systematic comparison between six different implied beta estimators, which provides some guidance for applications and …

The low (high) abnormal returns of stocks with high (low) beta - the beta anomaly - is one of the most persistent … important driver of the beta anomaly. The beta anomaly is no longer detected when beta-sorted portfolios are neutralized to … beta anomaly is concentrated in stocks with low levels of institutional ownership and it exists only when the price impact …

The capital asset pricing model has failed to explain the effect of systematic risk (referred to as beta) on actual … study analysis empirically confirms a positive relationship between overnight returns and beta and a negative relation … between daytime returns and beta. Furthermore, this paper aims to determine that empirical results are mostly the same with …

This paper estimates linear and non-linear GARCH models to find optimal hedge ratios with futures contracts for some of the main European stock indexes. By introducing non-linearities through a regime-switching model, we can obtain more efficient hedge ratios and superior hedging performance in...

Economic theory suggests that households should invest their financial wealth in a combination of cash and a well-diversified equity portfolio. Yet, many households' equity investments are strongly concentrated in a few assets. Attempts to explain this discrepancy have included low levels of...

The stochastic volatility model usually incorporates asymmetric effects by introducing the negative correlation between the innovations in returns and volatility. In this paper, we propose a new asymmetric stochastic volatility model based on leverage and size effects. The model is a...

Value-at-Risk (VaR) forecasting generally relies on a parametric density function of portfolio returns that ignores higher moments or assumes them constant. In this paper, we propose a new simple approach to estimation of a portfolio VaR. We employ the Gram-Charlier expansion (GCE) augmenting...
