GFI appoints new head of credit indexes

Margolies was formerly head of GFI’s single-stock derivatives desk in London. In the new role, he will be based in New York and report to senior managing director Don Fewer.

He takes on some responsibilities held by John Piluso, a senior credit derivatives broker, who will now move elsewhere in the firm. GFI said the move was part of a broader restructuring in North American indexes.
