Plus, the temptation must be strong for the bank to push more aggressively into non-IB activities. Its 3Q saw an 8% year-over-year boost in mortgage loan originations, for example, a number that could have been better. As it might well be in the future given the improvements in the housing market. Why continue to let big six rival and mortgage powerhouse Wells Fargo ( WFC 0.18% ) take much of that business? Perhaps with more resources and a greater concentration on the segment JPMorgan Chase can hitch on a big ride on that wave.
