The New York Stock Exchange (ICE) announced plans on Friday to expand weekday trading in the US stock market to 22 hours a day.
That would mean that the NYSE Arca – the main electronic exchange in the United States – would allow trading Monday through Friday from 1:30 a.m. to 11:30 p.m. Eastern Time, excluding holidays. The NYSE’s core trading session is currently weekdays from 9:30 a.m. to 4:00 p.m.
“The NYSE’s initiative to expand U.S. equity trading to 22 hours a day, 5 days a week underscores the strength of our U.S. capital markets and the growing demand for our listed securities around the world,” said Kevin Tyrrell, head of markets at the NYSE. “As the steward of the U.S. capital markets, the NYSE is pleased to lead the way in enabling exchange-based trading for our U.S. listed companies and funds for investors in time zones around the world.”
This is because the rise of alternative trading platforms has made established institutions wary. In May 2023, mobile trading platform Robinhood (HOOD) said it would begin allowing trading of select stocks and Exchange Traded Funds (ETFs) on its app from 8 p.m. Sunday through 8 p.m. Friday – 24 hours a day, five days a week.
But what the NYSE has that most rivals don’t is volume. All U.S. securities, or approximately 8,000 securities listed on U.S. exchanges, including ETFs, are traded on the exchange. With the new hours, all US-listed stocks, ETFs and closed-end funds would be available for trading on NYSE Arca 22 hours a day.
Trading on NYSE Arca during the new extended hours will still be approved by the Depository Trust & Clearing Corporation, which also recently announced plans to extend hours, the NYSE said. These changes still need regulatory approval.
