Rothschild & Co, the blue-blooded banking group, has enjoyed a surge in its share price just days after announcing a set of “excellent” half-year results.

The investment bank’s share price rose 5% to €35.95 during morning trading on September 27, a jump that came two days after it announced a 12% revenue uplift to €1bn, and a 56% increase in profit to €164m, compared to the same period a year ago.
