As is generally the case, UBS Warburg topped the manager activity rankings for both agency and non-agency MBS, according to final results from Thomson Financial's RMBS 2003 first-half league tables.
UBS edged out its competitors in the first half of this year with $64.03 billion in proceeds and a 14.1% market share. However, the perennial leader did not top its performance over the same period last year. In the first half of 2002, UBS outpaced other firms by a bigger market share -16.6%. However, it sold less last year with proceeds of $53.68 billion in the first half of 2002.
