The heads of the two biggest US banks by assets, JP Morgan and Bank of America, have said their trading businesses are set to close the year on a strong note as investor activity has picked up in the wake of the US presidential election.

JP Morgan chief Jamie Dimon said at a Goldman Sachs financial services conference that his bank expects fourth-quarter trading revenue to be up around 15% from a year earlier. Bank of America head Brian Moynihan signalled a similar gain for his bank's fixed-income trading business.
