By allowing for imperfectly informed markets and the role of private information, we offer new insights about observed deviations of portfolio concentrations in domestic relative to foreign risky assets, or "home bias", from what standard finance models predict. Our model ascribes the "bias" to...

We test the existence of a time-series relationship between the aggregate idiosyncratic volatility and the market index return at the global level by introducing various global measures of aggregate idiosyncratic volatility. We offer four definitions of aggregate global idiosyncratic volatility...

Considerable attention has been devoted in the financial literature to excessive portfolio concentrations in domestic risky assets relative to those predicted by standard finance models – generally identified as “home bias” – across international markets. The innovation we offer is...

This paper shows that market breadth, i.e. the difference between the average number of rising stocks and the average number of falling stocks within a portfolio, is a robust predictor of future stock returns on market and industry portfolios for 64 countries for the period between 1973 and...

The hedge fund industry has grown from $200 billion in assets under management around the turn of the millennium to now over $3 trillion. Many reports have criticized hedge funds for poor performance, particularly since the 2008 global financial crisis (GFC). In this paper, I seek to demystify...

Spillover effects from equity momentum to credit markets have been shown to lead to excessive premia and, simultaneously, reduced risk measures in credit securities. Here, we present an intuitive theory for this anomaly based on the premise that equity momentum drives leverage to invoke rating...

Black-Litterman model provides a reasonable platform to portfolio optimization and asset allocation by presenting an equilibrium state of the markets and only deviating from that equilibrium state with forward-looking strategic views. Index of Economic Freedom (IEF) can be used as a handy tool...
