Citadel Biggest Nasdaq Share Broker in September, Crain’s Says

Oct. 14 (Bloomberg) -- Citadel LLC, the Chicago-based firm run by billionaire Kenneth Griffin, handled more share volume on the Nasdaq Stock Market in September than any other brokerage, according to Crain’s Chicago Business.

The firm is not required to disclose its trading volume, according to the Crain’s article, which cited “informed sources.”

Citadel’s Griffin told the newspaper his firm executes about one in eight U.S. stock trades and one in five stock option trades and recently started trading so-called penny stocks and international shares.
