Goldman Sachs Group Inc. is the biggest broker on the upstart U.S. stock platform created by IEX Group Inc., according to a memo IEX sent some clients.
Goldman Sachs said last week that markets would be well-served if the five-month-old venue achieved “critical mass.” The dark pool, which has ambitions to become an exchange, was built with defenses against the fastest traders. Yesterday, in a memo obtained by Bloomberg News, IEX said Goldman Sachs has more than double the volume of the No. 2 broker.
