We perform an event study analysis to determine short-term abnormal stock returns following the Brexit referendum. Moreover, we examine whether firm-level internationalization helps explaining abnormal returns. We find that stocks of firms with higher proportions of domestic sales realized more...

We examine the predictability of government bond returns using a deep sample spanning 70 years of international data across the major bond markets. Using an economic, trading-based testing framework we find strong economic and statistical evidence of bond return predictability with a Sharpe...

Political risk relates to both the ability and the willingness of governments to repay debts. We find that bond prices only slowly adapt to changes in political risk. The expected bond returns for countries whose political risk ratings have improved are higher than those for countries whose...

We introduce the realized co-range, a novel estimator of the daily covariance between asset returns based on intraday high-low price ranges. In an ideal world, the co-range is five times more efficient than the realized covariance, which uses cross-products of intraday returns, when sampling at...

The average alpha of mutual funds is an indication of whether it pays off to invest in actively managed funds. In this study we show that a substantial part of the variation in the average alpha can be explained by exogenous factors. The most important factors are the average expense ratio, the...

We find increasingly large variations in returns from momentum strategies in recent years. Momentum strategies did not earn significant excess returns during the period of 1993-2004 which was due to their poor performance over the period from 2001-2004. Using sub-samples of smaller...
