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 and do not reopen until 9:30 AM the next business day, even when the underlying stock keeps moving in the after-hours session. A smaller group of broad ETF options runs an extra fifteen minutes until 4:15 PM, and a few index products such as SPX and VIX trade on a near 24-hour schedule. Separately, if you hold an expiring contract, you have until 5:30 PM Eastern on expiration day to tell your broker whether to exercise it, though your broker’s own deadline is almost always earlier.
Regular Hours for Stock and ETF Options
Equity options trade from 9:30 AM to 4:00 PM Eastern, matching the core session of the major U.S. exchanges. When the closing bell rings, these contracts stop. If the underlying stock gaps up or down on earnings released at 4:05 PM, you cannot buy, sell, or close the corresponding option until the following morning.
The reason is pricing infrastructure. Options quotes depend on continuous, transparent data from the underlying stock, and market makers set bid-ask spreads based on real-time volume. In the thinner after-hours equity market, those spreads would widen sharply and the models that keep options fairly valued would become unreliable. Concentrating activity in the regular session keeps execution costs lower.
Any options order submitted outside the 9:30 AM to 4:00 PM window sits in the queue until the next trading day and fills at whatever price the market offers at the open, not the price you saw when you placed it. On expiration Friday, a queued order will not execute in time at all.
The 4:15 PM Close for Broad ETF Options
Options on a specific group of broad-market and sector ETFs continue trading for fifteen minutes after the stock market closes. The list includes 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 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 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, check whether your specific product qualifies, since the list is exchange-specific and gets updated periodically.
Near 24-Hour Trading for SPX and VIX Options
Certain index products go much further. S&P 500 Index options (SPX) and Cboe Volatility Index options (VIX) trade on a nearly 24-hour weekday schedule through Cboe’s Global Trading Hours platform. VIX options, for example, are available from 8:15 PM to 9:25 AM Eastern in the overnight session, then during regular hours from 9:30 AM to 4:15 PM, followed by a curb session until 5:00 PM.2Cboe Global Markets. VIX Options Product Specifications The only dead zone is a roughly three-hour window in the late afternoon.
This 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 without waiting for the 9:30 AM bell. Access depends on your brokerage, though. 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.
One boundary worth noting: most index options are European-style, meaning they can only be exercised at expiration.3Cboe Global Markets. Index Options Benefits European Style Stock and ETF options are American-style and can be exercised any day before expiration.
The Exercise Window From 4:00 PM to 5:30 PM
Once an option stops trading, 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 on the business day of expiration to submit a final exercise or do-not-exercise instruction. For an option that expires on a non-business day, the deadline falls on the preceding business day.4FINRA. 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. Miss your broker’s cutoff and you lose the ability to make a manual decision, even though the regulatory window has not technically closed. Check your broker’s specific deadline well before expiration day.
During this window, the option is not trading. You cannot sell it, and its market price is frozen. The only question is whether the strike price makes exercising worthwhile given where the underlying stock is trading right now.
Contrary Exercise Advice
To override the automatic exercise process, you submit what the industry calls a Contrary Exercise Advice, or CEA. This instruction tells the clearinghouse either to not exercise a contract that would otherwise be automatically exercised, or to exercise one that would not be. Your brokerage handles the submission through the exchange or the OCC’s electronic system.5Nasdaq. ISE Options 6B Exercises and Deliveries A CEA can be canceled and resubmitted up until the cutoff time. For customer accounts, brokers have until 7:30 PM Eastern to file the CEA with the exchange, but your personal deadline is what matters, because the firm needs lead time to process your instruction.
Automatic Exercise and After-Hours Price Risk
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.6FINRA. 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.7The Options Clearing Corporation. File No. SR-OCC-2022-009 – EXHIBIT 5 Rules
Automatic exercise protects you from losing a profitable position through oversight, but it becomes a trap when the underlying stock moves against you in after-hours trading. 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. Then at 5:00 PM the company releases a weak earnings report and the stock drops to $97. If you fail to submit a do-not-exercise instruction before your broker’s deadline, you are automatically assigned 100 shares at $100 when the stock is worth $97, locking in a $300 loss before the next morning begins.
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. Because the option did not meet the automatic exercise threshold, you would need to file an affirmative exercise instruction before the 5:30 PM cutoff, and realistically before your broker’s earlier deadline.
This is why many experienced traders close expiring positions before the 4:00 PM bell rather than gambling on the after-hours gap. The ninety minutes between the close and the exercise deadline is not a time for passive observation.
Pin Risk for Option Sellers
Sellers face the mirror-image problem, and in some ways it is worse because they cannot control what the buyer decides to do. If you have written an option that is near the money at the close, you have no idea whether you will 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 is most acute when the stock closes right at or near the strike price. You will not find out whether you have been assigned until the next business day.
A scenario that catches sellers off guard: you have 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 after hours, and the put buyer exercises before the 5:30 PM deadline. You are now obligated to buy 100 shares at $100 when they are worth $96, and if the stock keeps falling over the weekend, the loss deepens before Monday.
The standard practice among options 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 is trivial compared to an assignment surprise from an after-hours price swing.
What Happens After Exercise
Once an option is exercised, the resulting stock purchase or sale settles on a T+1 basis, meaning the next business day. The U.S. moved to T+1 settlement for equities and options on May 28, 2024.8FINRA. Understanding Settlement Cycles – What Does T+1 Mean for You Exercise a call on Friday and you own the shares by Monday. Get assigned on a short put, and you need to pay for the shares by Monday.
This matters when your account doesn’t have the cash. An automatic exercise on a call with a $150 strike means your account needs $15,000 (100 shares times $150) by the next business day. In a margin account, the resulting stock position carries a 50% initial margin requirement under Regulation T, so that $15,000 purchase requires at least $7,500 in available cash or margin equity. If your account falls short, your broker will issue a margin call, and you have a limited window to deposit funds before the broker liquidates the position. Waiting for the stock to rise does not satisfy a Regulation T call.
Cash-settled index options avoid this entirely. Instead of exchanging shares, the OCC credits or debits the dollar difference between the settlement value and your strike price, multiplied by the contract multiplier.9Cboe. Why Option Settlement Style Matters You wake up the next business day with cash added or subtracted, not a stock position and not a margin call. Options on individual stocks and ETFs like SPY are physically settled, so exercise leaves you holding actual shares that you need capital or margin capacity to support.
