90% of financial trades in US are by 6 publicly held financial firms
Most of that trading in the United States—more than 90 percent—is generated by just six big, publicly held financial firms. Two are JPMorgan Chase and Morgan Stanley, the twin offspring of the House of Morgan, that exclusive club across the street from the Exchange. The others are Goldman Sachs, Wells Fargo, Bank of America, and Citigroup.
