In the meantime, E*Trade, which has struggled to keep up with competitors TD Ameritrade and Charles Schwab, has appointed the chairman of its board Frank Petrilli to be the firm’s interim CEO. Petrilli is getting $500,000 a month to fill the temp job. Fleming is well-regarded on Wall Street and is reportedly close to Citadel Investment chief Ken Griffin, who is one of E*Trade’s largest outside shareholders. Fleming joined Morgan Stanley in late 2009 and is a rising star at the firm. Before that he was the President and COO of Merrill Lynch, and was instrumental is inking the acquisition of Merrill by Bank of America at the height of the financial crisis, which is widely seen as having saved Merrill from collapse. Nonetheless, Fleming left the combined firm shortly after the deal was completed. Griffin reportedly approached Fleming about taking over the top slot at E*Trade back in 2009, but Fleming decided to go to Morgan Stanley instead.
