Three more staff have left NCB Stockbrokers. Mr Adrian O'Connell, Mr Tom Nolan and Ms Ashling Treacy are understood to have resigned to take up various positions in the financial services sector. Mr O'Connell and Mr Nolan held senior equity sales positions, while Ms Treacy worked in equity research. The move follows the departure of eight senior personnel from NCB earlier this month to set up a rival stockbroking firm, Merrion Capital.
