Options Risk Management
Compare premium risk, assignment exposure, expiration behavior, volatility sensitivity, and defined versus undefined option risk.
Core concepts
What to understand
Keep the process direct: define the risk, calculate it, and enforce the limit.
2
Assignment risk
Short American-style options can be assigned before expiration while the position remains open.
3
Expiration risk
In-the-money contracts can create stock obligations, exercise, or assignment near expiration.

RISK MODEL
Risk process
Apply it in order
Risk calculations should happen before the order is submitted.

Map expiration obligations
Know the share quantity and cash needed if exercise or assignment occurs.
Control contract liquidity
Spread and open interest affect entry, adjustment, and exit cost.

1. Maximum loss on a long call purchased for $3.00 is normally:
A standard equity option multiplier is commonly 100, so $3.00 premium represents $300 before fees.
2. When can an American-style short option be assigned?
Assignment can occur before expiration; likelihood varies with moneyness, time value, and events.
3. Does premium received equal maximum profit and maximum risk for a short put?
Premium is the maximum profit, while assignment can create a much larger purchase obligation and loss.
4. Sell one 50-strike put for $1.20. Maximum loss if the stock goes to zero?
Assignment obliges the writer to buy 100 shares at $50 = $5,000; the $120 received reduces the loss: (50 − 1.20) × 100 = $4,880.
Practical rules
- Know maximum loss and assignment obligation before entry.
- Close or manage short options before expiration when obligations are unwanted.
- Include spread, time decay (theta), implied-volatility sensitivity (vega), and gap scenarios.
Common mistakes
- Treating premium received as the amount at risk.
- Ignoring early assignment and ex-dividend risk.
- Holding contracts into expiration without sufficient buying power.
