Professor Nicolas Bollen is a prolific publisher and expert on hedge funds and mutual funds, Nick Bollen’s work has been referenced throughout academia and mainstream media. Two of Nicolas’s recent papers were published in the Journal of Finance: ‘In Hedge Fund Risk Dynamics: Implications for Performance Appraisal’, in which Nicolas Bollen, along with co-author Bob Whaley, studied how to measure time variation in the risk exposures of hedge funds; and ‘Do Hedge Fund Managers Misreport Returns? Evidence from the Pooled Distribution’, Nicolas Bollen and coauthor Veronika Pool discovered a robust empirical anomaly: the frequency of observing monthly returns just above zero is dramatically higher than the frequency of observing monthly returns just below zero. The paper was highlighted in The Wall Street Journal and has been downloaded over one thosand times since it was made publicly available. In a subsequent paper, ‘Patterns in Hedge Fund Returns and the Risk of Fraud’, published in The Review of Financial Studies, Nicolas Bollen and coauthor Veronika Pool show that a family of quantitative flags based on peculiarities in returns, including the discontinuity they discovered previously, can be used to measure operational risk. His current work is focused on a study of hedge fund replication products, and an analysis of models for predicting hedge fund failure, with a particular focus on times of systemic market crisis. Nicolas Bollen holds a Ph.D. in Finance from Duke University.
