Do options trade after hours? For the most part, no. Options on individual stocks and most ETFs stop trading at 4:00 PM Eastern Time along with the underlying stock market. A short list of broad ETF options runs an extra fifteen minutes to 4:15 PM, and a small group of index options, notably SPX and VIX, trade on a nearly 24-hour schedule. On expiration day, one more clock keeps running after trading ends: you have until 5:30 PM ET to submit exercise or do-not-exercise instructions, though your broker’s internal cutoff is almost always earlier.
When Regular Options Trading Starts and Stops
Standard equity and ETF options trade from 9:30 AM to 4:00 PM Eastern Time, matching the core session of the major U.S. exchanges. When the closing bell rings, these contracts stop trading. If the underlying stock gaps sharply higher or lower in the after-hours session, you cannot buy, sell, or close the corresponding option until the next morning.
The restriction exists because options pricing depends on continuous, transparent data from the underlying stock. Market makers rely on real-time volume to set competitive bid-ask spreads. In the thinner after-hours equity market, those spreads would widen significantly and the pricing models that keep options fairly valued would become unreliable. Concentrating activity in the regular session keeps execution costs lower for everyone.
Any options order submitted outside the 9:30 AM to 4:00 PM window queues until the next trading day. It will fill at whatever price the market offers at the open, not at the price you saw when you placed it. That matters most on expiration Friday, when a queued order won’t execute in time to affect a contract that’s about to disappear.
ETF Options That Run to 4:15 PM
Options on a specific group of broad-market and sector ETFs continue trading for fifteen minutes after the stock market closes, until 4:15 PM Eastern Time. The list includes widely held funds like the SPDR S&P 500 ETF (SPY), Invesco QQQ Trust (QQQ), iShares Russell 2000 ETF (IWM), and SPDR Dow Jones Industrial Average ETF (DIA), along with dozens of sector funds and volatility products. It keeps growing. In early 2026, options on the Vanguard S&P 500 ETF (VOO) were added to the 4:15 PM session across multiple exchanges.1Cboe. Change to Daily Closing Time for Options on a Certain Exchange Traded Product
The extra fifteen minutes give institutional hedgers a buffer to react to closing-auction imbalances and late-breaking news. If you trade options on sector ETFs or broad indexes through an ETF wrapper, confirm whether your specific product qualifies for the 4:15 PM close. The list is exchange-specific and gets updated periodically.
Index Options That Trade Nearly 24 Hours
A few index products go much further than an extra fifteen minutes. S&P 500 Index options (SPX) and Cboe Volatility Index options (VIX) trade on a nearly 24-hour schedule during the work week through Cboe’s Global Trading Hours platform. VIX options, for example, are available from 8:15 PM through 9:25 AM Eastern Time in the overnight session, then trade during regular hours from 9:30 AM to 4:15 PM, followed by a curb session until 5:00 PM.2Cboe Global Markets.

Around-the-clock access connects global financial centers, so a portfolio manager in Tokyo or London can hedge U.S. equity risk during their own business hours. For domestic traders, it means you can react to overnight geopolitical events or economic data releases without waiting for the 9:30 AM bell. Access depends on your brokerage firm. Many brokers require additional permissions or higher margin levels for overnight index trading, so verify your account settings before assuming you can place an order at midnight.
The Exercise Window From 4:00 to 5:30 PM
Once an option stops trading on expiration day, the contract doesn’t just vanish. A separate legal phase begins in which the holder decides whether to exercise. Under FINRA Rule 2360, option holders have until 5:30 PM Eastern Time on the business day of expiration to submit a final exercise or do-not-exercise instruction. For the rare option that expires on a non-business day, the deadline falls on the preceding business day.3FINRA. FINRA Rules – 2360 Options
Most brokerage firms set their own internal deadlines earlier than the 5:30 PM cutoff. A 4:30 PM or 5:00 PM deadline is common, because the broker still needs time to process your instruction and transmit it to the clearinghouse. If you miss your broker’s cutoff, you lose the ability to make a manual decision about that contract, even though the regulatory window hasn’t technically closed. Check your broker’s specific deadline well before expiration day.
During this window the option is no longer trading. You can’t sell it, and its market price is frozen. The only question is whether the strike makes exercising worthwhile given where the underlying stock sits right now.
Automatic Exercise and Contrary Instructions
The Options Clearing Corporation runs an exercise-by-exception system that automatically exercises expiring options unless a contrary instruction is filed. For equity options on stocks and ETFs, any contract that finishes at least $0.01 in the money based on the closing price gets automatically exercised.4FINRA. Regulatory Notice 10-36 – Amendments to Standardized Options Exercise Procedures For standard index options with a multiplier greater than one, the threshold is $1.00 per contract.5The Options Clearing Corporation. File No. SR-OCC-2022-009 – EXHIBIT 5 Rules
To override the automatic result, you submit what the industry calls a Contrary Exercise Advice, or CEA. This instruction tells the clearinghouse either not to exercise a contract that would otherwise be automatically exercised, or to exercise one that would not be. Your brokerage firm handles the submission through the exchange or the OCC’s electronic system.6Nasdaq. ISE Options 6B Exercises and Deliveries A CEA can be canceled and resubmitted up until the cutoff. For customer accounts, brokers have until 7:30 PM Eastern Time to file the CEA with the exchange, but again, your personal deadline is what matters, because the broker needs lead time.
After-Hours Price Risk on Expiring Options
Automatic exercise protects you from losing a profitable position because of an oversight or a technical glitch at the close. But it creates a trap when the underlying stock moves against you in the after-hours session.
Consider a call option with a $100 strike. The stock closes at $100.50, so the option is $0.50 in the money and scheduled for automatic exercise. By 5:00 PM the company releases a weak earnings report and the stock drops to $97 in after-hours trading. If you don’t submit a do-not-exercise instruction before your broker’s deadline, you’ll be automatically assigned 100 shares at $100 when the stock is already worth $97, locking in a $300 loss before the next morning even starts.
The reverse scenario is equally dangerous. An out-of-the-money put might look safely worthless at 4:00 PM, but a post-market drop in the stock could make you wish you had exercised it. Since the option didn’t meet the automatic exercise threshold, you’d need to file an affirmative exercise instruction before the 5:30 PM cutoff, and realistically before your broker’s earlier deadline.
Option sellers face the mirror-image problem, and in some ways it’s worse because they can’t control what the buyer decides to do. If you’ve sold a contract that’s near the money at the close, you have no idea whether you’ll be assigned. The buyer might exercise, might not, or might file a contrary instruction based on after-hours price movement. This uncertainty is called pin risk, and it’s most acute when the stock closes right at or near the strike. You won’t find out whether you’ve been assigned until the next business day.
Say you’ve sold a put with a $100 strike. The stock closes at $100.50, so the put is out of the money and you expect it to expire worthless. But the stock drops to $96 in after-hours trading and the buyer exercises before the 5:30 PM deadline. You’re obligated to buy 100 shares at $100 when they’re worth $96, and if the stock keeps falling over the weekend, the loss deepens before you can react on Monday morning.
The standard practice among experienced sellers is to spend a few cents to buy back short positions before the close on expiration day, even when they look safely out of the money. The cost of buying back a nickel-wide option is trivial compared to the potential assignment surprise from an after-hours price swing. Many buyers close out expiring positions before 4:00 PM for the same reason. The ninety minutes between the close and the exercise deadline is not a time for passive observation.
A Note on Same-Day (0DTE) Options
The rise of zero-days-to-expiration options has made this after-hours exercise window a routine concern rather than an occasional one. A 0DTE contract is one that expires at the end of the current trading day. Roughly 1.5 million 0DTE contracts trade on SPX alone on a given day, accounting for nearly half of all SPX options volume.
If you hold a 0DTE contract through the close, you’re immediately in the exercise-decision zone with no chance to trade out the next morning. SPX is cash-settled, so an in-the-money position becomes a cash credit or debit rather than a stock assignment, but 0DTE contracts on individual stocks and physically-settled ETFs put you right into the after-hours price-risk scenarios above. Some brokers will automatically liquidate expiring positions before the close rather than let you carry the exercise risk, which can mean getting filled at a bad price in the final minutes of the session. Know your broker’s policy before you hold a same-day option into the last hour.
