Quick Definition

The ratio comparing the potential loss (risk) to the potential gain (reward) of a trade or investment, expressed as risk:reward.

What Is Risk-Reward Ratio?

The risk-reward ratio compares how much you stand to lose versus how much you could gain on a trade. It's a fundamental tool for determining whether a trade is worth taking.

How It Works:

  • Risk = Entry Price - Stop Loss Price
  • Reward = Target Price - Entry Price
  • Ratio = Risk / Reward

Common Risk-Reward Ratios:

RatioMeaningRequired Win Rate
1:1Risk $1 to make $1>50% to profit
1:2Risk $1 to make $2>33% to profit
1:3Risk $1 to make $3>25% to profit
1:5Risk $1 to make $5>17% to profit

Example Trade:

  • Buy stock at $50
  • Stop loss at $47 (risk = $3)
  • Target at $59 (reward = $9)
  • Risk-Reward = 1:3

Why It Matters: Even with a 40% win rate, a 1:3 risk-reward ratio is profitable:

  • 10 trades: 4 winners × $9 = $36, 6 losers × $3 = $18
  • Net profit: $18 on 10 trades

Professional Minimum: Most professional traders won't take a trade with less than 1:2 risk-reward. Many aim for 1:3 or better.

Application to Investing:

  • Value investors: Buy at significant discount to intrinsic value (built-in risk-reward)
  • Growth investors: Upside potential should be 3x+ the downside risk
  • Portfolio level: Expected return should adequately compensate for portfolio volatility

R:R = (Entry - Stop Loss) / (Target - Entry)
