NYSE introduced that the extended trading hours will start at 1:30 AM Eastern Time and continue until 11:30 PM. This "22-hour" trading system will apply to all stocks, ETFs, and closed-end funds listed in the United States.

For Chinese investors, this change means that future nyse US stock trading hours (during daylight saving time) will close at 11:30 AM together with A shares, and then reopen at 1:30 PM in the afternoon.

It is reported that the extended trading hours mentioned here still fall under the commonly known pre-market and after-hours trading for US stocks. Trading US stocks outside of normal trading hours (9:30 AM-4:00 PM) requires regulatory approval. NYSE stated that the clearing of extended trading hours will continue to be handled by DTCC (Depository Trust & Clearing Corporation), which recently announced an extension of their operational hours.

Kevin Tyrrell, nyse's Head of Market, said the decision to extend trading hours highlights the increasing global demand for US stocks. NYSE is pleased to offer US stock trading services to traders from various time zones globally, leading the market development.

Fun fact: A history of changes in US stock trading hours

Although it may sound like a big deal for exchanges to change trading hours, at least in the USA, changes are quite common.

Take the NYSE as an example, their continuous trading began in 1871, typically opening at 10 a.m. and closing between 2 p.m. and 4 p.m. in 1887, market participants unanimously decided to set trading hours from 10 a.m. to 3 p.m. Monday to Friday, with half-day trading on Saturday mornings. The history of Saturday trading continued until it was canceled in 1952.

An interesting change occurred in 1968, as trading volume surged but computers were not yet widely available. The increased paperwork workload led to the backend being unable to process all trades. Starting in June of that year, the NYSE closed trading on Wednesdays, which lasted until after New Year's Day in 1969.

Over the next decade, with the advancement of computer technology, the NYSE and NASDAQ gradually fixed trading hours from 9:30 a.m. to 4 p.m., which remains the normal trading period today.

However, against the backdrop of exchange competition, the NYSE introduced after-hours trading in 1991. Initially only for an hour, it was later extended to four hours (4 p.m. to 8 p.m.). Subsequently, pre-market trading was gradually opened up, now extended to 4 a.m. opening.
