Dr. Guanhao Feng wins AQR Insight Award



Dr Guanhao (Gavin) Feng, Assistant Professor of the Department of Management Sciences, won the 2018 AQR Insight Award for the paper “Taming the Factor Zoo”, written with Professor Stefano Giglio of Yale University and Professor Dacheng Xiu of the University of Chicago.

The AQR Insight Award, sponsored by AQR Capital Management, recognises exceptional academic papers that offer original, intelligent approaches to issues in the investment world. Every year, top academics from around the world are invited to submit unpublished papers for review. This year, two papers including “Taming the Factor Zoo” tied for first place, and the recipients would share a US$100,000 prize.

In “Taming the Factor Zoo”, Dr Feng and the co-authors proposed a new methodology based on machine learning and model selection techniques, which allows researchers to test and evaluate if a new factor better explains the cross-section of asset prices when combined with existing factors. The authors then apply the model to a variety of recently proposed factors and determine that with a few exceptions — including profitability and investment — the new factors are redundant, failing to offer greater explanatory power.

“This paper deals with one of the most vexing and topical problems in empirical finance — how to judge whether results are ‘real’ or just the output of concerted data mining,” AQR's co-founder Cliff Asness says. “This is a topic anyone serious about factor investing has worried about.”
