JPMorgan Chase & Co. and Lehman Brothers Inc. tied for first place for the quality of their U.S. fixed-income investment services in a new Greenwich Associates survey of 1,300 institutional investors. That stellar attention to detail no doubt helped both of them also win–again in a tie–the No. 1 spot in market share as well.

Deutsche Bank, Goldman Sachs Group and Banc of America Investment Services took third, fourth and fifth place respectively, in terms of market size. When it comes to service, Deutsche and Goldman Sachs shared the third-place slot.

The survey also revealed that hedge funds are the most important focus for fixed-income dealers. Lehman Brothers has built up the biggest share in this segment, followed by Deutsche and JPMorgan, which are essentially tied for second place. Hedge funds also give the highest scores for service to Lehman and JPMorgan, followed at some distance by the Credit Suisse First Boston, Bear Stearns, Deutsche and Goldman Sachs in a four-way tie, says Dev Clifford, Greenwich Associates managing director.
