Risk/Reward Ratio Definition

The risk/reward ratio marks the prospective reward an investor can earn, for every dollar he or she risks on an investment. Many investors use risk/reward ratios to compare the expected returns of an investment with the amount of risk they must undertake to earn these returns. Consider the following example: an investment with a risk-reward ratio of 1:7 suggests that an investor is willing to risk $1, for the prospect of earning $7. Alternatively, a risk/reward ratio of 1:3 signals that an investor should expect to invest $1, for the prospect of earning $3 on his investment.
