The Treynor ratio, also known as the reward-to-volatility ratio, is a performance metric for determining how much excess return was generated for each unit of risk taken on by a portfolio. Excess return in this sense refers to the return earned above the return that could have been earned in a risk-free investment.
Although there is no true risk-free investment, treasury bills are often used to represent the risk-free return in the Treynor ratio. Risk in the Treynor ratio refers to systematic risk as measured by a portfolio's beta. Beta measures the tendency of a portfolio's return to change in response to changes in return for the overall market. In essence, the Treynor ratio is a risk-adjusted measurement of return based on systematic risk.
It indicates how much return an investment, such as a portfolio of stocks, a mutual fund, or exchange-traded fund , earned for the amount of risk the investment assumed. If a portfolio has a negative beta, however, the ratio result is not meaningful. A higher ratio result is more desirable and means that a given portfolio is likely a more suitable investment. Since the Treynor ratio is based on historical data, however, it's important to note this does not necessarily indicate future performance, and one ratio should not be the only factor relied upon for investing decisions.
Ultimately, the Treynor ratio attempts to measure how successful an investment is in providing compensation to investors for taking on investment risk. The Treynor ratio is reliant upon a portfolio's beta—that is, the sensitivity of the portfolio's returns to movements in the market—to judge risk.
The premise behind this ratio is that investors must be compensated for the risk inherent to the portfolio, because diversification will not remove it. The Treynor ratio shares similarities with the Sharpe ratio , and both measure the risk and return of a portfolio. The difference between the two metrics is that the Treynor ratio utilizes a portfolio beta, or systematic risk, to measure volatility instead of adjusting portfolio returns using the portfolio's standard deviation as done with the Sharpe ratio.
A main weakness of the Treynor ratio is its backward-looking nature. He notes how the Treynor Ratio is used to justify risks in investments. Basically, am I getting bang for my buck? Robert Merton knew Treynor well. Merton credits Treynor with bringing more mathematical analysis to finance.
That was his bridge. Bruce I. Jacobs is a principal of Jacob Levy Equity Management. He also credits Treynor for bringing mathematical formulas to better analyze stocks and mutual funds.
He also credits the Treynor Ratio with acknowledging the importance of beta when analyzing a stock. The Treynor formula builds on the work of fellow economist William Sharpe. Lo noted that the capital asset pricing model championed by economists is vital to the mutual fund industry.
Michael B. The Treynor formula builds on a previous measurement of the Sharpe Ratio. Both formulas can be beneficial to an investor to assess mutual fund investments. William Sharpe created the formula to help investors understand the risk of an investment in relation to its return. The Sharpe Ratio is similar to the Traynor Ratio because they both assess risks of portfolios. While both formulas have similarities, there are differences between the two ratios.
However, the Sharpe Ratio measures the performance of a portfolio based on the overall total risk of a portfolio. A standard deviation measures the investment risk in a mutual fund. The higher the Sharpe ratio, the better for a mutual fund.
A Sharpe Ratio of 1 and over is considered good for a mutual fund. A negative Sharpe Ratio means the expected return may be negative. Both formulas can effectively measure the performance of a mutual fund. However, there are two differences between the measurements. The Sharpe Ratio can be applied to all portfolios that are in specific sectors. In specific sectors, specific mutual funds may have unsystematic risk as to the best measure of risk.
In that case, the Sharpe Ratio may be the better formula because it measures overall risk. However, with the Treynor Ratio, there is a difference. The Treynor Ratio measures systematic risk. Unsystematic risk is not a factor with diversified mutual funds. Because of that, the Treynor Ratio can measure systematic risk. The Treynor Ratio can be a better metric to evaluate the performance of a well-diversified mutual fund portfolio. Some financial experts say that the metric has a downside. Michael Sury is a lecturer in finance at the University of Texas at Austin and studies the Treynor index.
Sury because it only looks at past performance. Importantly, by definition, it is a backward-looking ratio. Some financial experts like Aherns believe that a mathematical analysis may not be the best way to analyze stocks for beginning traders. In addition, Aherns also noted that taking on more risk may benefit them more than using the Treynor formula to calculate risk.
He believes that two factors are more crucial to evaluate mutual funds. No more panic, no more doubts. While the Treynor Ratio may not be for every investor, the Treynor formula could be a good option for measuring risk. In the rest of the article, I will analyze comparisons of 10 mutual funds. I will look at their financial statistics to compare the Treynor Ratios of the assets.
He recently tweeted about resisting the order on Twitter. I will be on the line with everyone else. I will explain the Treynor Ratio of the fund with a risk-free rate of 0. So, what could be a better representation for such a risk-free return rate than the return available on government securities.
So typically, the rates available or offered on government bonds Treasury Bills , etc. Then only we will be able to identify and understand whether the market return is adequately compensating the market risk. Again, every market security usually offers a higher rate of return than the risk-free return. In other words, there should be a reward for sustaining volatility or investing in a high-risk product. In other words, the ratio tries to find out the extra or additional returns earned. Moreover, the excess or additional return that this ratio assesses is the return that had been made or could be earned over and above risk-free return.
Treynor Ratio is extensively useful in measuring the excess return against the risk attached to particular security over the risk-free rate of return considering the additional risk. Though the securities or investment portfolio is diversified to balance the risk and return, the systematic risk always persists due to the volatile behaviour of the market. This ratio provides better analysis and evaluation of the entire investment portfolio for better returns.
