Understanding Position Sizing: Risk Management 101
Guys, let's talk position sizing. This isn't about how much you want to put into a trade, it's about how much you can afford to lose on a single trade. A common rule is risking no more than 1-2% of your total trading capital per trade. If your account is $10,000, that means your maximum loss on any given trade is $100-$200.
So, if you're looking at a setup in $PLTR and your stop loss implies a $5 move against you before you're out, and you want to risk $200, you'd divide your maximum dollar risk by the dollar risk per share ($200 / $5 = 40 shares). This means you'd buy 40 shares, not 100 or 1000, irrespective of the stock's price today at $173. It's a foundational concept often overlooked, leading to blow-ups. Stay disciplined.
The 1-2% rule is widely cited, but sticking to it rigidly can be challenging depending on volatility and typical stop loss distances. It's often more of a guideline than a hard limit for many. Also, the discussion around capital preservation often overlooks the potential for opportunity cost when excessively small positions are taken, leading to suboptimal returns even on winning trades.
