Wall Street investment banks, loathed by investors in 2011 and hobbled by weak trading last year, are poised for a return to the spotlight.

JPMorgan Chase & Co., Goldman Sachs Group Inc. and Morgan Stanley are among U.S. banks reporting fourth-quarter results this week amid a rise in fixed-income and equity trading and the most mergers and acquisitions since 2008. Investment-banking and trading revenue probably jumped 44 percent in the period from a year earlier, according to estimates by Betsy Graseck, a Morgan Stanley analyst in New York.
