What Happens When a Covered Call Is Assigned?
When a covered call is assigned, the buyer of your call option exercises their right to purchase your shares at the strike price. Your broker automatically transfers the shares from your account at the strike price, regardless of the current market price. You keep the premium you received when you sold the call, and you receive the strike price per share in cash. Assignment typically occurs at expiration if the stock price is above the strike price, but it can happen at any time (early assignment).
Assignment is not a negative outcome for covered call writers. In fact, it represents the maximum profit scenario because you earn both the capital gain from stock appreciation (up to the strike) and the full option premium. The only potential downside is the opportunity cost if the stock continues rising beyond the strike price, but this was a known trade-off when you sold the call. Professional covered call writers view assignment as a successful trade outcome.
Many beginners fear assignment, but it simply means you sold your stock at the agreed-upon price. Your total profit includes the premium received plus any capital gain from purchase price to strike price. Assignment means the trade worked exactly as designed.
Calculating Your Assignment Profit
- 1Capital gain = ($105 - $95) × 100 = $1,000
- 2Premium income = $3.50 × 100 = $350
- 3Total profit = $1,000 + $350 = $1,350
- 4Total return = $1,350 / ($95 × 100) = 14.21%
- 5Effective sale price = $105 + $3.50 = $108.50
- 6Opportunity cost = ($112 - $105) × 100 = $700 (gains you missed)
The Assignment Process: Step by Step
What Happens During Assignment
Assignment Scenarios Comparison
| Stock at Assignment | Capital Gain | Premium Kept | Total Profit | Opportunity Cost |
|---|---|---|---|---|
| $105 (at strike) | $1,000 | $350 | $1,350 | $0 |
| $108 | $1,000 | $350 | $1,350 | $300 |
| $112 | $1,000 | $350 | $1,350 | $700 |
| $120 | $1,000 | $350 | $1,350 | $1,500 |
| $130 | $1,000 | $350 | $1,350 | $2,500 |
Notice that your profit is the same regardless of how high the stock goes above the strike. The opportunity cost increases, but your actual realized profit remains $1,350. This is the fundamental trade-off of covered calls: you exchange unlimited upside for immediate premium income and a known maximum return.
What to Do After Assignment
- Consider selling a cash-secured put at or below the old purchase price to potentially re-enter the stock at a lower cost (the wheel strategy)
- Evaluate whether to repurchase the stock at current prices if you remain bullish
- Invest the proceeds in a different opportunity if the stock appears overvalued
- Review the trade results to improve your strike selection for future covered calls
- Account for tax implications: determine if the gain is short-term or long-term
- If using the wheel strategy, wait for a pull-back before selling the put to get a better entry price
When your covered call is assigned, the premium received is added to your sale proceeds for tax purposes. If you held the stock for more than one year AND the call was a qualified covered call, the stock gain may qualify for long-term capital gains rates. However, the premium itself is always treated as short-term. Consult your tax advisor for your specific situation.
