Sizing a Tesla trade
Position sizing answers one question: how many shares can I take so a loss only costs what I planned to risk? You need three numbers — your account balance, the percentage you're willing to risk, and how far your stop sits from your entry.
Worked through on Tesla: a $10,000 account risking 1% is $100 on the trade. Buying at 412.00 with a stop at 398.00 risks $14.00 per share, so $100 ÷ $14.00 = 7 shares. Widen the stop and your size shrinks; tighten it and your size grows — but your dollar risk stays fixed every time.
Questions
How many shares of Tesla should I buy?
Divide the dollars you're willing to lose by your risk per share. Shares = (account balance × risk %) ÷ (entry − stop). On a $10,000 account risking 1%, that's $100 ÷ your per-share risk.
What is risk per share on Tesla?
Risk per share is simply the distance between your entry and your stop in dollars. If you buy Tesla at $412.00 with a stop at $398.00, you're risking $14.00 per share — so your total loss is that number multiplied by your share count.
How much should I risk per trade?
Most disciplined traders risk 0.5–2% of their account per trade. Risking a small fixed percentage means no single Tesla loss can seriously damage your account, and your position size scales automatically as your balance changes.
What is a good risk-reward ratio?
Risk-reward compares the distance to your target against the distance to your stop. At 1:2, winning 40% of your trades is profitable; at 1:3, 30% is enough. Below 1:1 you need a very high win rate just to break even.
