Heteroskedasticity in returns may be explainable by trading volume. We use different volume variables, including surprise volume—i.e. unexpected above-average trading activity—which is derived from uncorrelated volume innovations. Assuming weakly exogenous volume, we extend the Lamoureux and...

Purpose – The paper aims to model multiple-period market risk forecasts under long memory persistence in market volatility. Design/methodology/approach – The paper proposes volatility forecasts based on a combination of the GARCH(1,1)-model with potentially fat-tailed and skewed innovations...

We examine risk factors that explain daily changes in aggregate credit default swap (CDS) spreads before, during and after the 2007–2009 financial crisis. Based on the European iTraxx CDS index universe, we document time-variation in the significance of spread determinants. Before and after...

We address credit cycle dependent sovereign credit risk determinants. In our model, the spread determinants' magnitude is conditional on an unobservable endogenous sovereign credit cycle as represented by the underlying state of a Markov regime switching process. Our explanatory variables are...

This paper addresses market risk prediction for high frequency foreign exchange rates under nonlinear risk scaling behaviour. We use a modified version of the multifractal model of asset returns (MMAR) where trading time is represented by the series of volume ticks. Our dataset consists of...

We propose and test novel multifactor models of daily mutual fund performance. To this aim, we set up equity style indices and derive risk factors, which nest the established Fama and French (1992) and Carhart (1997) factors. We add two additional risk factors, namely idiosyncratic risk and...

The subprime-related 2007/2008 global financial crisis represented a major economic challenge. In order to prevent such episodes of market failure, it is vital to understand what caused the crisis and which lessons are to be learned. Given the tremendous bailout packages worldwide, we discuss...
