The Globe and Mail reports in its Tuesday edition that Canaccord Genuity Group has lost its head of U.S. investment banking, the second big departure at Canada's largest independent brokerage in the past week. The Globe's Niall McGee writes that Canaccord says Dan Coyne left the firm for "personal reasons." Mr. Coyne joined Canaccord after the Canadian dealer acquired his previous employer, Boston-based Adams Harkness Financial Group, in 2006. Mr. Coyne had been with Adams Harkness since 1998. He was promoted to head of United States banking last year. Unnamed sources say Mr. Coyne was consistently among the firm's biggest producers in the U.S. Last week, veteran London-based banker Piers Coombs also departed Canaccord. Mr. Coombs, who was head of Canaccord's European equity capital markets business, jumped ship to Irish brokerage Goodbody Stockbrokers. Mr. Coombs had been with Canaccord since 2007. Previously, he worked for Morgan Stanley. Back in its home market, a string of senior Canadian bankers have left Canaccord since the summer. Sanjiv Samant and Justin Bosa departed in June for bank-owned dealers. In August, Pierre Fleurent left for a position outside of banking.
