Steven Cohen’s Venture Firm Backs 24-Hour Stock-Trading Startup

Hedge-fund billionaire and New York Mets owner Steven A. Cohen is backing a startup that wants to let investors trade stocks 24 hours a day, seven days a week.

Point72 Ventures, Mr. Cohen’s early-stage venture-capital fund, is leading a $14.25 million funding round for 24 Exchange. The companies announced the transaction Wednesday after it was reported earlier by The Wall Street Journal.
