JP Morgan more than doubled its net investment banking profits in the third quarter compared to a year ago, providing the perfect send off to former co-chief executive Bill Winters, who left the Wall Street giant just over two weeks ago.

Net profits from investment banking hit $1.9bn (€1.3bn) in the third quarter, up from $882m in the same period last year and a 31% increase on the second quarter, according to the bank's results for the period released today. The figure is an ideal send-off for Winters from the division he jointly-led until late last month.
