Agency considers biggest overhaul of stock-market structure since mid-2000sUpdated Dec. 14, 2022 12:22 pm ET
WASHINGTON—Regulators are set to propose the biggest changes to U.S. stock-market rules since the mid-2000s, aiming to give small investors better prices on their trades and reduce some advantages enjoyed by high-speed trading firms.
The Securities and Exchange Commission is preparing to vote on four proposals, along with a separate final rule related to insider trading, at a meeting on Wednesday. If a majority of the SEC’s five commissioners vote to issue the proposals, they will be open to public comment until at least March 31 before the agency can decide whether to finalize them.
