A Brief Look at Position Sizing: Not Just About Leverage
There's a common misconception, particularly with newer traders, that position sizing is solely about how much leverage you're using. While leverage certainly amplifies the impact of your position size, the core of intelligent position sizing is actually about managing risk relative to your total capital. It's about determining how much capital you're willing to expose on any single trade, irrespective of whether you're using 2x or 100x leverage.
Take, for instance, a hypothetical trade on $SAP. Let's say your analysis suggests a potential downside to $180 from the current $185.99, and you're aiming for a move to $195. If your total trading capital is $100,000, and you decide that you are only willing to risk 1% of your capital on this specific trade, that means your maximum dollar risk is $1,000. Given a $5.99 per share risk ($185.99 - $180), you would divide your maximum dollar risk ($1,000) by your per-share risk ($5.99) to determine the number of shares you can afford to buy: roughly 166 shares. This calculation holds true whether you're trading spot or using a CFD with leverage. The leverage only dictates the initial margin requirement, not the underlying capital at risk. It's a critical distinction often overlooked, leading to disproportionate losses when a trade goes sideways. Even on something as volatile as $MATIC, currently at $0.2826, applying a similar risk-based approach to position sizing is far more sustainable than simply going all-in because it 'feels right.'
