A rumor circulating the market this week that four Fleet Securities bankers were set to move was definitively quashed. Mike Cunningham, Todd Dahlstrom, Bill Maag and Mark DuFour, who work in sales and trading roles, were rumored to be moving ahead of the merger with Bank of America. Sources familiar with the people responded by saying: “It’s rubbish. People are speculating.” The bankers involved either declined comment or did not return calls. DuFour was traveling and could not be reached. The Royal Bank of Scotland was a bank named as the destination, but bankers there said no such move is in the works.
