NYSE Expands Trading Beyond the Bell. An Expert Weighs In.

The New York Stock Exchange expanded options trading hours on Monday, giving investors more time to trade contracts tied to some of America's biggest companies as exchanges compete for business beyond the traditional trading day.

The launch on NYSE American Options covers 29 stocks and exchange-traded funds, including Nvidia, Bank of America, the SPDR S&P 500 ETF Trust and the iShares Russell 2000 ETF. Investors can trade eligible contracts from 7:30 a.m. to 9:25 a.m. Eastern time, with an additional afternoon session running from 4 p.m. to 4:15 p.m.

NYSE, owned by Intercontinental Exchange, is joining Cboe in expanding access to options on individual companies and ETFs.

Cboe announced extended sessions for 25 single stocks and five ETFs, with its new schedule also taking effect Monday.

The changes give traders an earlier opportunity to adjust positions when news breaks before the opening bell. Corporate announcements and economic developments can move share prices outside regular hours, creating demand for access to the derivatives investors use to speculate or manage exposure.

Options give buyers the right, without an obligation, to purchase or sell an underlying asset at a specified price within a defined period. Their value can shift with the stock price, expected volatility, and the time remaining before expiration.

Michael Martin, VP of Market Strategy at the trading platform TradingBlock, told IBT that "Investors can already trade futures and crypto nearly around the clock, so it was probably only a matter of time before equities followed suit. The biggest benefit is accessibility, particularly for international investors and those looking to trade market-moving news outside normal trading hours."

For exchanges, the expansion also brings traditional securities trading closer to the continuous access available in cryptocurrency markets. Prediction markets and some perpetual futures products have further broadened the availability of trading throughout the week.

Yet Monday's initial activity offered a restrained start to the expanded schedule. Tesla options attracted a little more than 3,000 contracts ahead of the company's Wednesday earnings report, according to SpotGamma data cited by CNBC. Nearly all were call options, and their combined value was below $100,000.

The activity likely included traders rolling existing positions, CNBC reported. Rolling generally involves closing one options position and opening another, often with a different expiration date or strike price.

That distinction matters when interpreting the concentration in calls. Although buying a call can express an expectation that shares will rise, call volume alone does not establish that traders are making fresh bullish bets.

Martin added that "just because a market is open doesn't mean there's sufficient liquidity. Overnight trading volumes are still relatively small, which often translates into wider spreads, poor execution prices, and more price swings. I would say this is very concerning for retail traders who don't understand liquidity risks."

The subdued debut contrasts with broader growth in trading outside regular hours. CNBC reported that Cboe's extended-hours options activity recently reached a record average exceeding 199,000 contracts daily. That figure describes existing extended-hours business rather than Monday's newly available stock options alone.

NYSE is also preparing a separate expansion that would bring stock trading much closer to an overnight schedule. NYSE Arca is targeting Dec. 6 for trading 23 hours a day, five days a week, subject to the conditions outlined by the exchange. Its planned schedule would run from 9 p.m. through 8 p.m. the following day, leaving one hour for maintenance, processing and the transition between trading dates.
