Wall Street is getting antsy waiting for Citigroup ( C) to turn itself around. Three years after taking over for the legendary wheeler-dealer Sandy Weill, CEO Chuck Prince has come under pressure from restive shareholders. Until a rumor-fueled rally late last year, shares of the nation's largest bank had fallen far behind archrivals Bank of America ( BAC) and JPMorgan Chase ( JPM), as Citi's slow growth and sagging domestic operations sent fans packing. Prince cooled his critics briefly in December by siccing head of investment banking Robert Druskin on the bank's runaway expenses. But with fourth-quarter earnings looming Friday morning, investors are eager to see signs that Prince has bigger plans. "Citi said, 'We see more opportunity pursuing stronger growth abroad,' but with pursuing that stronger growth comes risk," says Anton Schutz, president of Mendon Capital Advisors and the fund manager to Burnham Financial Services fund. He doesn't own Citi. "The Street is getting a little impatient." Druskin's hiring came as investors speculated that Citi might either split its retail and wholesale banking operations, or purchase a large U.S. banking company to beef up its domestic consumer business. Instead the company sees expansion outside of the U.S. as the key to improving it stock price. Last quarter Citi announced an assortment of smaller international acquisitions. At the same time, Prince pledged to cut investment spending in half this year to hold down costs.
