Fiserv Deal Prompts Putsch at TD Ameritrade.

OMAHA – Last week’s acquisition of Fiserv’s brokerage business has prompted several hedge fund investors in TD Ameritrade to push for a sale of the online brokerage. Shares of Ameritrade jumped over the past week after company reported it had received a letter from investment funds Jana Partners and S.A.C. Capital Advisors urging the company to make a deal in the interests of the majority of shareholders. The two hedge funds said they would like to see Ameritrade combine with either E-Trade Financial Corp. or Charles Schwab Corp. The bid to sell the company came just days after it the Ameritrade acquired the Fiserv Brokerage Services and its $28 billion under management. Ameritrade is 40% owned by Canadian banking giant Toronto-Dominion Bank.
