Since the last three decades, advanced economies have been facing a substantial rise not only in the crude oil price but also in the oil price volatility. Quantifying the tail risk has become a prominent issue for investment decisions and risk management. This article reveals the existence of a...

We present a new volatility model, simple to implement, that combines various attractive features such as an exponential moving average of the price and a leverage effect. This model is able to capture the so-called 'panic effect', which occurs whenever systematic risk becomes the dominant...

Asymmetric volatility in equity markets has been widely documented in finance, where two competing explanations, as considered in Bekaert and Wu (2000), are the financial leverage and the volatility feedback hypothesis. We explicitly test for the role of both hypotheses in explaining extreme...

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,...
