Calmar ratio

Ratio of annualized return to maximum drawdown.

In brief: Ratio of annualized return to maximum drawdown.

Meaning in practice

The Calmar ratio makes strategies comparable whose main problem is not volatility, but deep periods of loss. Values above 1 are considered solid, above 3 are considered very good.

Context for investors and traders

For traders, this term is most useful when preparing and executing an order. Its meaning depends on the venue, liquidity, time frame and order type. A single reading is not a reliable buy or sell decision.

How to use this in practice

In practice, the term should be linked to a specific trading plan: entry, exit, position size and costs belong together. In short time frames, spread, slippage and delayed execution can quickly outweigh the theoretical benefit of an observation.

What to keep in mind

Write down which observation confirms or invalidates your assumption before trading. This keeps the term a decision-making tool rather than a retrospective justification for risk already taken.
