The Capital Asset Pricing Model (CAPM) predicts a positive relation between risk and return, but empirical studies find the actual relation to be flat, or even negative. This paper provides a broad overview of explanations for this ‘volatility effect' that have been proposed in different...

This paper shows that low-risk stocks significantly outperform high-risk stocks in the local China A shares market. The main driver of this low-risk anomaly is volatility, and not beta. A Fama-French style VOL factor is not explained by the Fama-French-Carhart factors, and has the strongest...

We examine the empirical relation between risk and return in emerging equity markets and find that this relation is flat, or even negative. This is inconsistent with theoretical models such as the CAPM, which predict a positive relation, but consistent with the results of studies for developed...

Betas are used in many applications ranging from asset pricing tests, cost of capital estimation, investment management and risk management. Beta needs to be estimated, and to reduce estimation error, shrinkage to its cross-sectional average value of one is often applied. Since beta is the...

Solvency II has one standard equity solvency capital requirement for type 1 or developed market stocks (39 percent) and one for type 2 or emerging market stocks (49 percent). As such, differences in financial economic risk of stock portfolios within developed or emerging markets do not influence...

This paper makes a breakdown of common Fama-French style equity factor portfolios into their long and short legs. We find that factor premiums originate in both legs, but that (i) most added value tends to come from the long legs, (ii) the long legs of factors offer more diversification than the...

In this paper we examine global tactical asset allocation (GTAA) strategies across a broad range of asset classes. Contrary to market timing for single asset classes and tactical allocation across similar assets, this topic has received little attention in the existing literature. Our main...
