Kevin Corgan, v.p., has moved to the investment-grade trading desk from his position as co-head of the junk desk. Corgan referred calls to Ed Canaday, a firm spokesman, who says the move was made because the investment-grade desk needed an experienced trader as trading volumes have increased on that desk due to market volatility. Prior to joining the high-yield desk, Corgan had worked in high-grade. Corgan now reports to Paul Huchro, head of the high-grade desk. Lester Brafman stays on as the sole head of Goldman's junk desk.
