Sell-Side? The sell side is that part of the financial sector which creates and markets financial instruments, like stocks, bonds, and foreign exchange, in the public market. It also incorporates private capital instruments, including placements of private debt and equity, in the mix. Sell-side professionals are, therefore, investment banks and brokers who design and service these financial products and sell them to the buy side, usually through institutional and individual investors. On Wall Street, firms engage in business as sell-side companies, with investment banks serving as facilitators between issuers of securities and investors and market makers who provide liquidity by trading in the public markets. Investment bankers and corporate finance advisors help companies raise funds in the private capital markets by issuing debt and stock.
