Nasdaq Inc. and Cboe Global Markets Inc., two of the biggest stock exchanges, challenged a new US Securities and Exchange Commission rule that changes the economic structure of how stocks trade.
The firms asked a court to review the SEC’s recently finalized national market structure regulation, also known as Reg-NMS, according to a petition, which they said was lodged with a United States appeals court in Washington.
