Options Expiration Guide — Dates, Rules, and What to Expect
Standard Expiration Dates
Most US equity options expire on the third Friday of each month at 4:00 PM Eastern. Weekly options expire every Friday. Some products (like SPX and VIX options) have additional expiration cycles.
| Expiration Type | When | Common Products |
|---|---|---|
| Monthly | Third Friday of each month | All optionable stocks and ETFs |
| Weekly (Weeklys) | Every Friday | Major stocks, SPY, QQQ, IWM, and popular names |
| Quarterly | Last business day of each quarter | Index options (SPX, NDX) |
| LEAPS | Third Friday of January, 1–3 years out | Available on most liquid underlyings |
What Happens at Expiration
In-the-Money Options (ITM)
Options that are $0.01 or more ITM at expiration are automatically exercised by the OCC (Options Clearing Corporation). If you’re long an ITM call, you’ll buy 100 shares. Long an ITM put, you’ll sell 100 shares. If you sold the option, you’ll be assigned.
Out-of-the-Money Options (OTM)
OTM options expire worthless. No action is taken. If you bought the option, you lose the premium paid. If you sold it, you keep the full premium collected.
At-the-Money Options (ATM)
Options right at the strike create uncertainty. The holder can choose to exercise or not. This “pin risk” is one reason experienced traders close positions before expiration rather than gambling on the outcome.
The Expiration Day Timeline
| Time | What Happens |
|---|---|
| Market Open (9:30 AM ET) | Last chance to close or roll positions |
| Market Close (4:00 PM ET) | Equity options stop trading. Final settlement price determined. |
| 4:00–5:30 PM ET | OCC processes exercises and assignments |
| 5:30 PM ET | Deadline for holders to submit Do Not Exercise (DNE) or contrary exercise notices |
| Evening/Overnight | Assignments posted to accounts |
Theta Acceleration Near Expiration
Theta (time decay) accelerates dramatically in the final days before expiration. An option with 30 days left loses time value gradually. The same option with 5 days left loses time value much faster. With 1 day left, decay is at maximum speed.
This matters for both buyers and sellers. Option buyers face rapid value erosion in the final week. Option sellers benefit from this acceleration — which is why many premium sellers target 30–45 day expirations and close at 50% profit before the final week.
Rolling Before Expiration
“Rolling” means closing your current option and opening a new one at a later expiration (and potentially a different strike). Traders roll to:
- Avoid assignment on short options that are ITM
- Extend a winning trade that hasn’t reached max profit yet
- Manage a losing trade by moving to a new strike or date for a credit
- Maintain a position like the Wheel Strategy without interruption
Common Expiration Mistakes
| Mistake | Consequence | Prevention |
|---|---|---|
| Letting spreads expire with stock between strikes | Assigned on one leg, unhedged stock position | Close all spreads before expiration |
| Forgetting about automatic exercise | Unwanted stock position or margin call | Monitor ITM options; close or submit DNE if needed |
| Holding OTM options hoping for a miracle | Premium decays to zero with no recovery | Set loss limits; don’t let hope replace analysis |
| Ignoring after-hours moves | Stock moves after close, making OTM options exercisable | Close positions before 4 PM on expiration day |
Key Takeaways
- Most equity options expire on the third Friday of each month at 4:00 PM ET.
- ITM options are automatically exercised by the OCC — even if only $0.01 in the money.
- Theta accelerates sharply in the final week, benefiting sellers and hurting buyers.
- Close spreads before expiration to avoid pin risk and partial assignment.
- Rolling is the standard way to manage positions approaching expiration without taking assignment.
Frequently Asked Questions
What time do options expire on expiration day?
US equity options stop trading at 4:00 PM Eastern on expiration day. However, the holder has until 5:30 PM ET to submit exercise instructions to their broker. Index options (like SPX) may have different settlement procedures — some settle based on Friday morning’s opening prices.
Do options always expire on Friday?
Usually, yes. Standard monthly options expire on the third Friday. Weekly options expire every Friday. If Friday is a market holiday, expiration moves to Thursday. Some index products have Monday, Wednesday, or end-of-month expirations.
What happens if I forget about an expiring option?
If it’s ITM by $0.01 or more, it will be automatically exercised. For long calls, you’ll buy 100 shares. For long puts, you’ll sell 100 shares (or go short if you don’t own them). This can trigger margin calls if you don’t have sufficient funds. If you don’t want exercise, submit a Do Not Exercise (DNE) notice through your broker before 5:30 PM ET.
Should I exercise my option or sell it before expiration?
Almost always sell it. When you exercise, you only capture intrinsic value. When you sell, you capture both intrinsic and any remaining time value. The only common exception is exercising a deep ITM call to capture a dividend — and even then, the math should be checked.
What is a LEAPS expiration?
LEAPS (Long-Term Equity Anticipation Securities) expire on the third Friday of January, typically 1–3 years in the future. They behave like regular options but with much more time value. As LEAPS approach their expiration year, they transition into regular monthly options.
