Pandemics, CAPM, and Factor Alpha

A discussion led by,

Dan diBartolomeo

Free Meeting

Forthcoming in Journal of Asset Management

Abstract
The COVID-19 pandemic has taught us a valuable lesson in terms of how factor returns and “alpha” should be interpreted.  In this presentation, we will discuss the more than thirty years of factor return history, while slightly modifying the our standard factor structure to account for the presence of “rare, extreme events” (e.g. the pandemic).  The resultant model is consistent with the Black (1972) version of CAPM where the zero-beta asset is has no correlation with the market portfolio but may have non-zero volatility.  It is also consistent with the work of Barro (2005) and Gabaix (2010) on rare events. The result is significant changes to the interpretation of the history of returns to many popular equity factors such as “value”, “momentum”, and “quality”.  We demonstrate both a statistically significant positive return to CAPM beta as a risk factor and a significant negative return to absolute volatility.  The only way both can be true is a negative return to idiosyncratic risk which we frame as a proxy for bankruptcy risk, and thus a firm level contribution to the presence of higher moments in the returns of the market portfolio.
