This ratio was developed by Jack Treynor to measure how well an investment has compensated its investors given its level of risk. The Treynor ratio relies on beta, which measures an investment sensitivity to market movements, to gauge risk. The premise underlying the Treynor ratio is that systematic risk--the kind of risk that is inherent to the entire market (represented by beta)--should be penalized because it cannot be diversified away.
