How To Manage Trade Risk
Risk management is the architecture that keeps one bad idea from rewriting your whole process.
Managing trade risk means deciding position size, invalidation, downside tolerance, and review rules before the trade tests your emotions.
Risk matters because research can be right and execution can still fail. Without sizing discipline and review rules, a solid idea can still become a damaging position.
- Match position size to liquidity, conviction, and event risk.
- Define what has to happen for the trade to be wrong before entering.
- Track your downside in portfolio context, not only one trade at a time.
- Write the thesis, catalyst, and invalidation in one place.
- Set size so the loss is survivable even if the idea fails fast.
- Review the process weekly so mistakes become visible before they become habits.
- Sizing based on excitement instead of structure.
- Moving stops only because the position feels painful.
- Ignoring correlation between positions when several names depend on the same theme.

Common questions
2 answersWhat is the biggest retail risk-management mistake?
Usually oversizing relative to conviction and liquidity. Size creates most of the emotional damage before the thesis itself does.
Should every trade have a stop?
Every trade should have an invalidation and a loss plan. Whether that is an automatic stop, manual exit, or smaller position depends on the style and liquidity.
