Why Position Sizing Matters

Risk Management

Position sizing is your first line of defense against large losses. By risking only a small percentage of your account on each trade (typically 1-2%), you ensure that no single trade can significantly damage your trading capital.

Consistency

Using a systematic approach to position sizing helps maintain consistent risk across all your trades, regardless of your confidence level in any particular setup.

Emotional Control

When you know your maximum loss before entering a trade, you're less likely to make emotional decisions like moving stop-losses or holding losing positions too long.

Long-term Survival

Proper position sizing allows you to survive losing streaks and stay in the game long enough for your edge to play out over many trades.

Position Sizing Best Practices

1

Risk 1-2% per trade

Most professional traders risk no more than 1-2% of their account on any single trade.

2

Always define your stop-loss first

Your position size should be determined by your stop-loss level, not your profit target.

3

Consider volatility

Highly volatile stocks may require smaller position sizes to maintain the same dollar risk.

4

Account for fees and slippage

Factor in commission costs and potential slippage when calculating your position size.
