# Sharpe Ratio Investopedia: All You Need to Know About Forex Trading

## What is the Sharpe Ratio?

The Sharpe Ratio is a mathematical measure, developed by the economist William Sharpe, which is used to measure the return on investment or portfolio adjusted for risk. It compares the excess return, or return in excess of the risk free return, to the total risk of the investment. This ratio can be used by investors to determine the risk profile of their investments and to compare different investments, stocks, or portfolios.

The Sharpe Ratio is also referred to as the Sharpe Index, Sharpe Measure, or Sharpe Ratio. It is often used in conjunction with other types of financial metrics to assess the risk of an investment strategy. For example, the Sharpe Ratio can be used in combination with the beta coefficient to determine the level of risk in the portfolio.

## How the Sharpe Ratio Works?

The Sharpe Ratio is calculated by taking the difference between the expected return of an investment and the risk free rate of return, and dividing it by the standard deviation of that investment. The Sharpe Ratio gives a number that indicates that the risk adjusted return of an investment is higher than its actual return. The higher the Sharpe Ratio, the better the return on investment.

The Sharpe Ratio can also be used to compare investments with different levels of risk. By comparing investments with the same expected return but higher risk, investors can more easily identify investments with the most attractive return versus risk ratio.

## Using Sharpe Ratio for Forex Trading

The Sharpe Ratio can be used to evaluate forex trading strategies. By looking at both the risk/reward ratio and the Sharpe Ratio, investors can more effectively assess their investment decision. This is especially important if the investor is new to forex trading and is unfamiliar with the risks involved.

For example, if a trader is looking to use a low risk strategy such as buying and holding, they can compare the Sharpe Ratio of different currencies to determine which investments are the most profitable. By comparing the Sharpe Ratio of different investments, investors can identify investments with a greater return per unit of risk.

The Sharpe Ratio is an important metric for forex traders and investors alike. By using the Sharpe Ratio to compare investments, investors can identify the investments with the lowest risk and highest return. In addition, the Sharpe Ratio can also be used to evaluate forex trading strategies, allowing investors to determine which strategies are the most profitable. By doing so, investors can maximize their return on investment and reduce their risk.

## What is Investopedia Sharpe Ratio?

The Sharpe ratio, developed by Nobel Laureate William F. Sharpe is a measure of risk-adjusted performance of an investment. It divides the return on an investment, less the risk-free rate, by the volatility of the investment over a set period of time. It compares the returns of an investment to that of the average investment and defines the extra return on the investment due to additional risk taken. A big number would mean that the investment has outperformed both the average and the investment with no risk.
