Risk Management: How Not to Go Broke
Lesson 6: How Not to Blow Up Your Account
Options are leverage machines. Without risk management, you're not trading — you're gambling with a predetermined expiration date on your account. Here's how the professionals stay alive.
The 1% Rule (Position Sizing)
Never risk more than 1-2% of your account on any single trade.
On a $25,000 account, that means max risk per trade = $250-$500. If you're buying a $2.00 option ($200 per contract), your stop-loss or max loss should be $250 — meaning you can buy 1 contract and risk the full premium, or size up with a tighter stop.
WSB Reality Check: Yes, this is boring. It also means you survive 50 losing trades in a row and still have an account. The guys posting 10,000% gains are the 0.01%. The ones who went to zero don't post.
The Kelly Criterion
The mathematically optimal bet size, given your edge:
f* = (bp − q) / b
Where:
f* = fraction of bankroll to bet
b = net odds received (profit / amount risked)
p = probability of winning
q = probability of losing (1 − p)
Example: You have a strategy that wins 55% of the time with a 1:1 risk-reward ratio. Kelly says bet (1 × 0.55 − 0.45) / 1 = 10% of your account. Most traders use half-Kelly (5%) because you never know your true edge.
Stop-Losses and Profit Targets
| Type | What It Does | Options-Specific |
|---|---|---|
| Hard Stop | GTC order that exits at a specific price | Set at option price, not stock price. Options gap past stops overnight. |
| Mental Stop | You manually exit when it hits | Requires discipline. Most traders lack it. |
| Time Stop | Exit if thesis hasn't materialized by X date | Critical for options. If you expected a move in 3 days and nothing happened, theta is eating you. |
| Profit Target | Take profit at a predetermined gain | Take 50% at target, let the rest ride. Many option traders use 25-50% profit targets. |
Portfolio-Level Risk
- Correlation Risk: 10 different tech stock calls aren't 10 independent bets — they all crash together.
- Sector Exposure: No more than 20-25% of your portfolio in one sector.
- Delta Exposure: Sum your total delta across all positions. If you're net long 500 deltas and the market drops 1%, you lose ~$500.
- Vega Exposure: Being net long vega across positions means an IV crush hurts everything simultaneously.
- Max Drawdown Limit: If your account drops 20% from its peak, stop trading for a week. Reassess. The goal is survival.
Common Risk Management Mistakes
❌ The Martingale Trap
Doubling down after a loss to "make it back." You lose $500, so you bet $1,000 to recover. Lose that, bet $2,000. This is how accounts go to zero in three trades. The market doesn't owe you a win.
❌ The Correlation Blind Spot
"I'm diversified — I have calls on AAPL, MSFT, GOOGL, NVDA, and AMD." No. That's 5 tech stocks. When the sector rotates, they all get crushed simultaneously. Look at your actual correlation matrix.
❌ Overstaying Your Welcome
Buying a 30 DTE call, the stock moves your way in week 1, you're up 40%... and you hold. By week 3, theta has eaten your gains and you're underwater. Take profits when your thesis plays out. You can always re-enter.
