A Good Sharpe Ratio: What It Means And How To Achieve It


When it comes to investing, one of the most important metrics to consider is the Sharpe ratio. The Sharpe ratio measures the risk-adjusted return of an investment and is a useful tool for determining whether an investment is worth the risk. In this article, we will explore what a good Sharpe ratio is, why it matters, and how to achieve it.

What is the Sharpe Ratio?

The Sharpe ratio was developed by Nobel laureate William F. Sharpe in 1966. It measures the excess return of an investment over the risk-free rate, divided by the standard deviation of the investment’s returns. In simpler terms, it measures how much return an investment generates for each unit of risk taken.

Why Does the Sharpe Ratio Matter?

The Sharpe ratio is an important metric because it allows investors to compare the risk-adjusted returns of different investments. A higher Sharpe ratio indicates that an investment has generated more return for each unit of risk taken, making it a more attractive investment option.

What is a Good Sharpe Ratio?

The ideal Sharpe ratio varies depending on the investor’s risk tolerance and investment objectives. Generally, a Sharpe ratio of 1 or higher is considered good, while a ratio of 2 or higher is considered excellent. However, it’s important to note that a high Sharpe ratio doesn’t necessarily mean an investment is without risk.

How to Achieve a Good Sharpe Ratio

There are several strategies investors can use to achieve a good Sharpe ratio. One approach is to diversify their portfolio across different asset classes, such as stocks, bonds, and commodities. This can help to reduce the overall risk of the portfolio while still generating returns. Another strategy is to invest in low-cost index funds, which track the performance of a market index such as the S&P 500. These funds typically have lower fees and expenses than actively managed funds, which can eat into returns and reduce the Sharpe ratio.

The Importance of Risk Management

While achieving a good Sharpe ratio is important, it’s also crucial for investors to manage risk. One way to do this is to set stop-loss orders, which automatically sell an investment if it falls below a certain price. This can help to limit losses and protect against market downturns. Another way to manage risk is to invest in assets with low correlation to the broader market. For example, investing in real estate or alternative assets such as private equity can provide diversification and reduce the risk of a portfolio.


In conclusion, the Sharpe ratio is an important metric for investors to consider when evaluating investment options. A good Sharpe ratio indicates that an investment has generated more return for each unit of risk taken, making it a more attractive investment option. By diversifying their portfolio, investing in low-cost index funds, and managing risk, investors can achieve a good Sharpe ratio and improve their overall investment performance.
