Omega by Marc Odo, CFA, CAIA, CFP
With the release of StyleADVISOR 8.1, Zephyr Associates has expanded the toolset used to understand the Omega ratio. Omega captures all four moments of a distribution: return, standard deviation, skewness, and kurtosis. In addition, Omega can be used to help understand any series of return data, whereas some of the traditional return/risk statistics used in finance are only useful if the returns happen to fall into a somewhat normal distribution pattern. Therefore, Omega is a useful metric when looking at absolute-return strategies or strategies that are not pegged to a market benchmark. When Omega is coupled with a cumulative distribution of returns chart, the two can offer insights into the tail-risk of an investment. Finally, Omega is quite valuable when analyzing a total portfolio’s suitability for meeting a target return.
