Commerzbank Securities plans to replace several staffers who have left the firm's U.S. and European offices in droves in recent months. Sam Gottesman, co-head of fixed income sales in New York, said the firm is working to both restaff and broaden many of its business operations. He declined to specify the areas the firm plans to beef up, although he noted the firm is in the process of hiring for structured credit, hedge fund sales and third-party distribution.
