Managing Assignment Risk
Learn when assignment is likely, how to prevent unwanted assignment, and strategies for handling early assignment gracefully.
Understanding Assignment
Assignment occurs when an option buyer exercises their right, and you (the seller) must fulfill your obligation:
- Put assignment: You buy 100 shares at the strike price
- Call assignment: You sell 100 shares at the strike price
When Does Assignment Happen?
Assignment is most likely when your option is:
- In-the-money (ITM) at expiration
- Deep ITM before expiration
- ITM just before an ex-dividend date (for calls)
| Situation | Assignment Likelihood |
|---|---|
| Option OTM | 0% |
| Option ATM at expiration | ~50% |
| Option ITM at expiration | ~100% |
| Deep ITM before expiration | Variable |
Early Assignment
Early assignment can happen at any time, but is more common when:
For Puts:
- Option is very deep ITM
- Near expiration with no time value
- Stock has dropped significantly
For Calls:
- Stock is trading above strike price
- Ex-dividend date approaching
- Time value is less than dividend amount
Preventing Unwanted Assignment
If you want to avoid assignment, you have several options:
- Buy to close - simply buy back the option
- Roll out - close current position, open later expiration
- Roll up/down - move strike further OTM
- Let it expire - only if you're sure it will be OTM
Rolling Strategy
Rolling is closing your current position and opening a new one in a single trade:
Roll Out (Same Strike, Later Date):
- Used when you want more time
- Collects additional premium
- Delays potential assignment
Roll Up/Out (Higher Strike, Later Date) - for calls:
- Gives stock more room to run
- Usually costs money (debit) or breaks even
- Preserves more upside potential
Roll Down/Out (Lower Strike, Later Date) - for puts:
- Reduces assignment risk
- May collect credit or cost money
- Lowers your potential purchase price
When to Accept Assignment
Assignment isn't always bad. Accept it when:
| For Puts | For Calls |
|---|---|
| You want to own the stock | You're happy with the profit |
| Strike is below your target price | Stock is overvalued at strike |
| You're ready to sell calls | You want to free up capital |
| Premium received was good | Better opportunities elsewhere |
Handling Assignment
When assigned on a put:
- Review your new position size
- Check if you're overweighted in the sector
- Set up your covered call plan
- Update your cost basis tracking
When assigned on a call:
- Calculate your total return
- Record the trade for taxes
- Move cash to your put-selling pool
- Look for your next put opportunity
Assignment and Taxes
Assignment has tax implications:
- Put assignment: Your cost basis = strike price - premium received
- Call assignment: Your sale price = strike price + premium received
- Track holding periods for long vs. short-term treatment
The Dividend Trap
For covered calls, beware of early assignment before ex-dividend:
Example:
- Stock at $52
- You sold $50 call
- Dividend of $0.50 tomorrow
- Call has $0.30 extrinsic value
Risk: Call buyer may exercise early to capture the $0.50 dividend since it's worth more than the $0.30 time value remaining.
Prevention: Roll or close calls before ex-dividend when extrinsic value is less than the dividend.
Quick Reference: Assignment Decisions
| Scenario | Recommended Action |
|---|---|
| Slightly ITM, 2+ weeks to expiration | Wait, may come back OTM |
| Deep ITM, any time | Consider rolling |
| ITM at expiration | Accept assignment |
| Call ITM before ex-dividend | Roll or close |
