The risk-to-reward ratio expresses the relationship between the potential loss and the potential gain of an investment position, with risk in the numerator and reward in the denominator. A ratio of 1:3 means the investor risks $1 for the potential to earn $3 — the same as a reward-to-risk ratio of 3:1, simply expressed differently. Professional traders and investors typically prefer to express this as reward-to-risk (reward first), emphasizing the potential gain, but the underlying concept is identical.

See Asymmetric Reward to Risk and Reward to Risk Calculation for comprehensive treatments of how this ratio is calculated, why it matters, and how it interacts with win rates to determine long-term profitability.

A favorable risk-to-reward ratio — where the reward substantially exceeds the risk — is the foundational requirement for any position to meet the Asymmetry® investment standard. Every position should be structured so that the maximum loss (if the thesis is wrong) is meaningfully smaller than the expected gain (if the thesis is right). This discipline, maintained consistently across many positions and market environments, creates the asymmetric return profile that drives superior long-term compounding.
