Members Exchange, the stock exchange newcomer backed by BlackRock and Wells Fargo & Co., is breaking with its peers on industry reforms.
In December, the Securities and Exchange Commission announced changes to its rules that would require certain exchanges to publish some of the currently private data that clients pay to have access to.
Nasdaq, the New York Stock Exchange, and Cboe Global Markets filed a lawsuit against the SEC on Friday in the Washington, D.C. Appeals Court, asking the court to prevent the rule from going through.
The lawsuit said that the rule is “arbitrary” and “capricious” and that it “does not promote efficiency, competition, and capital formation.”
