Revenues from equities trading at investment banks surged 42%, due in part to sustained growth in equity derivatives, according to a recent report from Boston Consulting Group.

The report, which finds the largest investment banks are increasingly directing their attention to Europe, the Middle East, and Africa (EMEA) says that the region now represents 36% of the industry's global revenues. The report says that in a break with the past some investment banks predict that in the next three to five years, up to 75% of revenue growth will come from outside the United States.

The Investment Banking and Capital Markets report also highlights a continued need for product innovation and technology investment to drive profit growth.
