The Low-Risk Anomaly: How Much is a Good Risk Estimate Worth?
2020-11-01T22:32:23Z | Ryan Poirier, ASA, CFA, FRM“Many academics and practitioners rely on standard, relatively basic methods to estimate and manage portfolio risk. This can impact an investment manager's ability to accurately target lower volatility stocks designed to exploit the well documented low-risk anomaly. This paper finds a hybrid risk estimate that mixes short-, medium-, and long-term variances leads to superior ex-post information ratios and alphas by properly aligning securities in the correct order (low risk to high risk). This risk estimate may be worth between US$420 million and US$1.9 billion annually, calculated from the overall size (US$75 billion) of the market. The significance of this estimate survives transaction costs, various time periods, and risk factor exposures.”
