## Treynor Performance Measure

A measurement of return on a portfolio in excess of what a riskless investment would have earned per unit of risk. It is calculated by taking the portfolio's rate of return, subtracting the return on the riskless investment (usually a Treasury bond), and dividing by the portfolio's beta. It is important to note that the Treynor performance measure does not account for the effect, if any, of active portfolio management. It is simply a measurement of actual returns. It is also called the return to volatility ratio.

## Treynor performance measure

A gauge of risk-adjusted portfolio performance. The measure is calculated by dividing the portfolio beta (a measure of market, or systematic risk) into the average difference between the portfolio's returns and returns on a risk-free asset. A higher number represents better performance by the portfolio manager. Compare Sharpe performance measure.

Similar to the Sharpe Ratio, the Treynor Ratio is a measurement of efficiency utilizing the relationship between annualized risk-adjusted return and risk.
To obtain the third group of performance measures, we use the average weekly portfolio return adjusted for the risk free rate divided by the standard deviation of returns and the estimated market beta to get the Sharpe Ratio and Treynor Ratio, respectively.
The second performance measure is the Treynor ratio (9) which also measures the excess return per unit of risk.

In order to evaluate both the performance and risk character of microfinance investment funds we shall use three risk measures, the standard deviation of returns of a portfolio, the historical portfolio beta coefficient and the R-squared of a portfolio as well as three performance measures largely adopted in the financial literature--so called Jensen's alpha, the Sharpe ratio and the Treynor ratio.
The analysis has been made on the basis of mean return, beta risk, co-efficient of determination, Sharpe ratio, Treynor ratio and Jensen Alpha.
Using market portfolio as a benchmark, some commonly used measures for evaluating the performance of the portfolios of stocks are Ex Post Alpha or Jensen's Coefficient (Jensen 1968), Reward-to-Volatility Ratio (RVOL) or Treynor Ratio (Treynor 1965), and Reward-to-Variability Ratio (RVAR) or Sharpe Ratio (Sharpe 1966).
Finally, the Treynor ratio (18) for both the test portfolio and benchmark was calculated and used as a means of comparison where the market return was taken as the return on the MSCI Global Index.
While the Sharpe ratio uses standard deviation measure of total risk (comprising systematic and non-systematic components), the Treynor ratio uses CAPM's beta as relative measure of systematic risk to divide fund risk premium.
