We investigate an index of returns on professionally managed currency funds and a subset of returns from 34 individual currency fund managers. Over the period 1990-2006, excess returns earned by currency fund managers have averaged 25 basis points per month. We examine the relationship of these...

This paper uses micro-level data on mutual funds from different financial centers investing in equity and bonds to study how investors and managers behave and transmit shocks across countries. The paper finds that the volatility of mutual fund investments is driven quantitatively by both the...

This paper analyzes the geographical preferences of hedge fund investors and the implication of these preferences for hedge fund performance. We find that funds of hedge funds overweight their investments in hedge funds located in the same geographical areas and that funds of funds with a...

Discussions of financial risk often fail to distinguish between risks that are consciously borne and those that are not. To understand the breeding conditions for financial crises the prime focus of concern should not be simply on large risk-taking per se, but on the unintended, or unanticipated...

We study stock returns over the period of the global financial crisis of 2007-2008 and identify three crisis "shock factors" related to unique features of the crisis: (1) the collapse of global demand, (2) the contraction of credit supply, and (3) selling pressure on firms' equity. All three of...

We provide a simple and intuitive measure of interdependence of asset returns and/or volatilities. In particular, we formulate and examine precise and separate measures of return spillovers and volatility spillovers. Our framework facilitates study of both non-crisis and crisis episodes,...

Despite their strong positive average returns across numerous asset classes, momentum strategies can experience infrequent and persistent strings of negative returns. These momentum crashes are partly forecastable. They occur in "panic" states - following market declines and when market...

Mutual funds change their risk levels significantly over time. This paper investigates the performance consequences of risk shifting, as well as the economic motivations and the mechanisms of risk shifting. Using a holdings-based measure of risk shifting, we find that funds that increase risk...

The level of diseconomies of scale in asset management has important implications for tests of manager skill and the expected level of performance persistence. To identify the causal impact of fund size on future returns, we exploit the fact that small differences in returns can cause discrete...
