SUMMARY:Department of Economics Seminar with Dr Daniele Bianchi, Queen Mary, University of London
DESCRIPTION:Speaker: Dr Daniele Bianchi, Queen Mary, University of London    Daniele's research interests span empirical asset pricing, financial econometrics, machine learning and Bayesian methods.    Abstract: The returns on conventional momentum portfolios exhibit a predominantly negative, time-varying skewness which deepens during the so-called ``momentum crashes''. This has important implications for the dynamics of the risk-return trade-off associated with momentum investing: the relation between the portfolio's expected return and its volatility is time-varying and depends on the conditional skewness of the returns. We explore the economic value of accounting for time-varying skewness to measure momentum risk by comparing the performance of different risk-managed momentum portfolios. A dynamic, skewness-adjusted maximum Sharpe ratio strategy significantly improves upon popular volatility-scaling approaches. Finally, we show that the dynamics of skewness in momentum returns cannot be fully reconciled with an asymmetric exposure to upside and downside market risk. https://events.st-andrews.ac.uk/events/school-of-economics-and-finance-seminar-32/
