Salomon Smith Barney was a prominent investment bank and brokerage firm in the United States. It was formed in 1997 through the merger of Salomon Brothers, a well-known bond trading firm, and Smith Barney, a respected brokerage. The firm provided a range of financial services, including investment banking, asset management, and wealth management. In 2003, Salomon Smith Barney was rebranded as Citigroup Global Markets after its parent company, Citigroup, decided to consolidate its financial services under a single brand. The firm played a significant role in the financial markets, serving both individual and institutional clients.
