When assets exhibit asymmetric dependence or joint downside risk, diversificationcan fail and financial markets may be prone to systemic risk. We analyze thedependence structure of risk factors in the US economy, using both correlations anda parsimonious set of copulas. We find evidence of...

A central role for economic policy involves understanding and reducing the impact of unexpected,extreme events. In this paper, we develop a simple economic framework with latentregime switches. This framework explains why investors and policymakers can decide not tohedge against extreme events,...

This paper develops a liquidity measure tailored to the foreign exchange (FX) market, quanties the amount of commonality in liquidity across dierent exchange rates, and determines theextent of liquidity risk premiums embedded in FX returns. The new liquidity measure utilizesultra high frequency...

A great proportion of stock dynamics can be explained using publicly availableinformation. The relationship between dynamics and public information may be ofnonlinear character. In this paper we offer an approach to stock picking by employing so-called decision trees and applying them to XETRA...

This paper examines properties of mean-variance inefficient proxies with respect to producing a linear relation between expected returns and betas. The numerical results of a Monte Carlo simulation show that in the CAPM slightly inefficient, positively weighted proxies cause an almost perfect...

While there is little controversy on the profitability of momentum strategies, their implementation is afflicted with many difficulties. Most important, chasing momentum can generate high turnover. Though there are already several attempts to make momentum strategies less expensive with respect...

Assessments of investors’ risk appetite/aversion stance via indicators often yields resultswhich seem unsatisfactory (see e.g. Illing and Aaron (2005)). Understanding howsuch indicators work therefore seems essential for further improvements. The presentpaper seeks to contribute to this...

Using a new data set on investor sentiment we show that institutional and individualsentiment proxy for smart money and noise trader risk, respectively. First, usingbias-adjusted long-horizon regressions, we document that institutional sentiment forecastsstock market returns at intermediate...

The puzzling evidence of seemingly high momentum returns is related to an understanding ofrisk as a simple covariance. If we consider, however, risk in higher-order statistical moments,momentum returns appear less advantageous.
