Over the last half-century, many of the developments and models used in finance assume the presence of a “risk-free rate”. This rate of return is used as a reference point or springboard for a vast array of analysis, including:

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.
