Assignment occurs when an option buyer exercises their rights, forcing the option seller to fulfill their obligation – buying shares for put sellers or selling shares for call sellers. It’s not a failure or mistake; it’s simply part of the contract you agreed to when collecting premium. For put sellers, assignment means buying 100 shares at the strike price. For call sellers, it means selling 100 shares at the strike price. Understanding assignment mechanics, probabilities, and management strategies transforms it from a feared outcome to just another step in the income generation process. The key is being prepared both mentally and financially for assignment before it happens.
How Assignment Works
Assignment is a mechanical process:
- Option buyer decides to exercise (usually at expiration if ITM)
- OCC randomly assigns sellers (you don’t know when)
- Broker notifies you (usually by Saturday morning)
- Shares appear/disappear (in your account Monday)
- Cash is debited/credited (at strike price × 100)
You have no control over assignment timing – only preparation.
Assignment Example – Put
Sold $50 put for $0.50 premium:
- Stock closes at $48 on Friday
- Assigned Saturday morning
- Monday: Own 100 shares
- Cost: $5,000 debit
- Effective basis: $49.50 (including premium)
Assignment Example – Call
Sold $52 call for $0.40 on shares owned at $48:
- Stock closes at $54 on Friday
- Assigned Saturday morning
- Monday: Shares gone
- Receive: $5,200 credit
- Total profit: $440 (gain + premium)
Assignment Probability
Not all ITM options get assigned:
Deep ITM: Nearly 100% assignment
Barely ITM: Variable assignment
- $0.01-0.50 ITM less certain
- After-hours movement matters
- Pin risk exists
OTM: Zero assignment risk
- No economic benefit to exercise
- Expires worthless
- Keep full premium
Delta as Assignment Predictor
- 0.20 delta: ~20% chance by expiration
- 0.50 delta: ~50% chance by expiration
- 0.80 delta: ~80% chance by expiration
This helps size positions appropriately.
Early Assignment
American options can be assigned before expiration:
Common Early Assignment Triggers:
- Deep ITM with no time value
- Dividend capture (calls)
- Hard-to-borrow stocks
- Major volatility events
Dividend Assignment Example:
- Own shares at $48
- Sold $50 call for $0.40
- Stock rises to $53
- $0.50 dividend announced
- Call buyer exercises early for dividend
- You keep premium but lose dividend
Managing Assignment Risk
Preparation prevents panic:
Before Selling Options
Capital Planning:
- Have cash for put assignment
- Own shares for covered calls
- Never use full buying power
- Reserve adjustment funds
Strike Selection:
- Only sell puts at prices you’d buy
- Only sell calls above cost basis
- Consider total position size
- Factor in sector exposure
Approaching Expiration
Wednesday Check: Assess all positions
- ITM positions need attention
- Calculate assignment impact
- Decide: roll, close, or accept
Thursday Decision: Final adjustments
- Last chance for cheap rolls
- Close if assignment unwanted
- Prepare for likely assignments
Friday Management: Monitor closely
- Watch pin risk positions
- No hoping – take action
- After-hours movement matters
After Assignment
Assignment isn’t the end – it’s a transition:
Put Assignment Response

- Sell covered calls immediately
- Continue income generation
- Target above cost basis
- Weekly or monthly options
- Exit if thesis changed
- Sell shares Monday
- Take loss, move on
- Don’t marry positions
- Average down if confident
- Sell another put

Assignment Fees and Logistics
Hidden costs to consider:
Assignment Fees: $0-20 per assignment
- Some brokers charge
- Factor into calculations
- May affect small positions
Settlement Timing:
- Options settle T+1
- Stock settles T+2
- Cash/margin implications
- Plan accordingly
Tax Implications:
- Put assignment starts holding period
- Call assignment triggers gain/loss
- Wash sale rules apply
- Track for taxes
The Assignment Mindset
Successful traders embrace assignment:
It’s Not Failure: You agreed to this price It’s Planned: Part of your strategy It’s Profitable: You kept premium It’s Temporary: Can exit anytime
Psychological Preparation
Before selling any option, ask:
- “Am I happy owning here?” (puts)
- “Am I happy selling here?” (calls)
- “Can I handle the capital requirement?”
- “What’s my post-assignment plan?”
If any answer is no, don’t sell the option.
Assignment in The Wheel Strategy
Assignment drives the wheel:
- Sell puts → Collect premium
- Get assigned → Own shares at discount
- Sell calls → Collect more premium
- Get assigned → Sell shares at profit
- Repeat → Compound returns
Assignment is a feature, not a bug.
Avoiding Unwanted Assignment
When assignment must be avoided:
Rolling Strategy:
- Roll before expiration week
- Target credit rolls
- Adjust strikes if needed
- Buy time for recovery
Close at Loss:
- Sometimes cheaper than assignment
- Preserves capital
- Avoids margin issues
- Clean slate
Never: Let hope drive decisions Always: Have a plan before selling
Common Assignment Mistakes
Surprise: Not monitoring positions Panic: Emotional response to assignment Overleverage: Too many obligations No Plan: Unsure what to do with shares
Assignment Best Practices
Build assignment into your system:
- Size for Assignment: Never sell more than you can handle
- Track Obligations: Know total potential assignment
- Maintain Reserves: Keep dry powder
- Have Exit Plans: Know your response
- Stay Mechanical: Remove emotion
Weekly Routine
- Monday: Check weekend assignments

Assignment is simply the fulfillment of the contract you created when selling options. Embrace it as part of your income strategy rather than fearing it.
