Perella seems to have some early momentum

As all of Wall Street knows, Joseph Perella is putting together this own boutique, as yet unnamed. Judging by his hires, he's having great success. The most recent addition is Bernard Gault of Morgan Stanley's Europe banking team. He will become a London-based partner. Phillip Yates of Merrill Lynch has also accepted a position. He will also be a London-based banker. So it would seem the inchoate firm has London covered.
