After-Hours Options Trading Guide
Published Sep 22, 2026
Updated Sep 22, 2026Options trading outside the regular U.S. session depends on the product, exchange and broker, so the stock can be moving even when a trader cannot trade the related option
- Most equity options still have more limited hours than the stocks they track, while major index options can trade during dedicated global sessions.
- After-hours moves in the underlying can change an option’s theoretical value before an executable options market is available.
- Extended-hours options markets can have thinner liquidity and wider spreads, making limit prices and product-specific rules especially important.
What Does After-Hours Trading Mean for Options?
The regular U.S. stock session runs from 9:30 a.m. ET/8:30 a.m. CT to 4:00 p.m. ET/3:00 p.m. CT. Stocks can trade before and after that window, and some brokerage firms like also provide access to overnight sessions. Options follow a different schedule.
A stock option only trades when an options exchange has an open session for that product and the trader’s brokerage firm supports access to it. The underlying stock can therefore make a large move at 4:15 p.m ET. while the related option has little or no tradable market.
That distinction is important around binary events like earnings, economic data and corporate announcements. The stock market can reprice immediately, but the option holder may have to wait for the next available options session before changing the position.
Do Standard Equity Options Trade in Extended Hours?
Regular trading hours for most U.S. equity options are concentrated around the core stock session. Some products trade until 4:15 p.m. ET, while standard single-stock options have historically had much narrower extended-hours access than the underlying shares.
Exchange rules are expanding. Cboe has received regulatory approval for morning and post-market sessions in designated high-volume equity option classes. The framework allows a morning session from 7:30 a.m. to 9:25 a.m. ET and a post-market session from 4:00 p.m. to 4:15 p.m. ET for eligible classes. Actual availability still depends on the option class, exchange rollout and brokerage access.
A trader should never assume that an option is tradable simply because the stock is printing in pre-market or after-hours trading. The order ticket and exchange schedule must be confirmed.
Index Options Are a Major Exception
Several broad index options have much longer trading windows. Cboe offers Global Trading Hours for products including SPX, XSP, VIX and RUT options. Those sessions provide access for much of the overnight period, in addition to regular U.S. trading hours.
That makes index options useful for traders who need to respond to overseas market moves, geopolitical headlines or economic releases that occur before New York opens.
The liquidity profile still changes by time of day. A contract that trades with a tight market during the U.S. cash session may show less depth overnight. Extended access gives a trader another window to act, but it does not guarantee the same execution quality.
What Happens to an Option When Earnings Move the Stock After Hours?
Assume a stock closes at $100 and a trader owns a 105-strike call that expires in two weeks. The company reports earnings at 4:05 p.m., and the stock jumps to $112 in after-hours trading.
The call is now economically more valuable because the underlying moved above the strike. That does not mean the trader can immediately sell the option. If the option class has no active post-market session through the trader’s broker, the position remains open until trading resumes.
The next options quote will also reflect more than the stock move. Implied volatility may fall after the earnings event, the bid-ask spread may open wide and the stock may move again before the option market becomes liquid. The final option price can differ sharply from a simple estimate based on the after-hours stock quote.
How Do You Handle Orders When Liquidity Is Thin?
Extended-hours options sessions deserve more price discipline. Some exchange sessions restrict order types and may prohibit market orders or stop orders. Brokerage firms can apply additional limits.
Limit orders give the trader control over the worst acceptable execution price. That protection becomes more valuable when the market is thin and the spread is wide.
Displayed quotes also need context. A two-sided market does not guarantee meaningful size. One contract on the bid and one on the offer can disappear quickly when the underlying moves. Traders should check spread width, quoted size and the underlying market before sending an order.
Can You Exercise an Option After the Market Closes?
An exercise instruction is not the same as an options trade. A holder may have the ability to submit exercise instructions after the market closes, subject to the brokerage firm’s cutoff and expiration procedures.
This becomes especially important on expiration day. A stock can cross an option strike after 4:00 p.m., changing the economics of exercise or assignment even after regular options trading has ended.
Traders holding expiring options should know the broker’s exercise cutoff before the closing bell. Waiting for an after-hours stock move to make the decision can leave very little room to respond.
How Do You Decide Whether to Trade Options After Hours?
Check three things before planning an options trade outside normal hours: the exchange session for that product, the broker’s supported hours and the order types allowed in that session.
Then treat the underlying market as a separate source of risk. If the stock trades for hours while the option does not, the position can accumulate delta, gamma and volatility exposure without an immediate exit.
Extended-hours options trading can be useful when access exists. The advantage comes from flexibility. The tradeoff is usually thinner liquidity, more complicated product rules and a greater need to control execution price.
Frequently Asked Questions
Some options trade outside regular hours, but access depends on the option class, exchange, and broker. Standard equity options have historically had limited extended-hours availability, though Cboe now permits designated high-volume classes to trade from 7:30–9:25 a.m. ET and 4:00–4:15 p.m. ET. Broad index options like SPX, XSP, VIX and RUT trade on longer Global Trading Hours sessions covering much of the overnight period. Confirm the exchange session, broker access, and allowed order types before trading — extended hours can also mean thinner liquidity and wider spreads.
The position stays open and keeps its existing delta, gamma, and volatility exposure until an options market is active, even while the stock keeps trading. This matters most around earnings and on expiration day, when a stock crossing a strike after 4:00 p.m. ET can change the economics of exercise or assignment. Confirm your broker's exercise cutoff in advance — exercise instructions follow separate rules and deadlines from options trading itself.
