UPSIDE AND DOWNSIDE BETA PORTFOLIO CONSTRUCTION: A DIFFERENT APPROACH TO RISK MEASUREMENT AND PORTFOLIO CONSTRUCTION

Download This Article

Abstract

Traditional financial measurements of risk are limited to variance-based methodologies. The most common measurement tool is beta. The beta calculation, however, is directionally agnostic and relies on the assumption of a normal distribution. This is a poor metric by which risk is measured, and is incomplete. The ability to break down beta into Upside and Downside beta allows investors the ability to more intelligently build risk into a portfolio. Using three-year trailing betas may also allow investors the ability to benefit from mean reversion and generate excess returns on a risk-adjusted basis.
