The big four Wall Street wirehouses have lost market share since the financial crisis in part because of their role in the crisis and “customer distrust,” according to Bing Waldert, a director of Cerulli Associates Inc. (See “Wirehouse market share has shriveled since crisis,” InvestmentNews). Merrill Lynch Wealth Management, Morgan Stanley Smith Barney, UBS AG and Wells Fargo & Co. have also lost market share by terminating lower producing brokers. While the wiehouses have tried to focus on high net worth clients, their share of that lucrative market has declined as well.
