Sell side is a term used in the financial services industry. The three main markets for this selling are the stock, bond, and foreign exchange market. It is a general term that indicates a firm that sells investment services to asset management firms, typically referred to as the buy side, or corporate entities. The sell side and the buy side work hand in hand and each side could not exist without the other. These services encompass a broad range of activities, including broking/dealing, investment banking, advisory functions, and investment research.
