Investment bankers and mergers-and-acquisition brokers are likely to receive a 25% increase in bonuses in 2006, according to Johnson Associates. Equity and fixed-income traders, along with prime brokerage executives, are expected to take home a 15% bonus. Compensation in general is expected to rise 15%, except for retail bankers, who may see their paychecks fatten by only 5% to 10%. The average Wall Street bonus last year was $125,500, which was a 10% boost over 2004. Goldman Sachs, Lehman Brothers, Merrill Lynch and Bear Stearns pay their employees the most, with Goldman Sachs shelling out more than half of their net revenues in the first two quarters of this year to pay salaries and benefits.
