Momentum Profits and Non-Normality Risks

This paper examines the role of non-normality risks in explaining the momentum puzzle of equity returns. It shows that momentum returns are not normally distributed. About 70 basis points of the annual momentum profits can be attributed to systematic skewness risk. This finding is pervasive across nine strategies and is reinforced when time dependencies in abnormal returns and risks are explicitly modeled. The analysis also reveals that the market and skewness risks of momentum portfolios evolve over the business cycle in a manner that is consistent with market timing and risk aversion. A revisited version of this paper was published in the June 2009 issue of Applied Financial Economics.

About EDHEC-Risk Climate Impact Institute

Marking the priority assigned by the School to sustainability issues and building on its research programmes exploring the relationships between climate change and finance, EDHEC-Risk Institute became EDHEC-Risk Climate Impact Institute in October 2022. The Institute's mission is to help private and public decision-makers manage climate-related financial risks and make the best use of the financial tools available to transition to low-emission and climate-resilient economies. The Institute’s research programmes explore the relationships between climate change and finance and our key ambition is to become a leading academic reference point for long-term investors, helping them to manage the asset-pricing implications of climate change as well as mitigation and adaptation efforts.
