Securities brokerage is a service that helps individuals and institutions buy and sell financial assets, such as stocks, bonds, and mutual funds. Brokers act as intermediaries between buyers and sellers, facilitating transactions on various exchanges. They may charge a commission or fee for their services, which can vary based on the type of trade and the brokerage firm. There are two main types of brokers: full-service and discount. Full-service brokers, like Merrill Lynch or Charles Schwab, offer personalized advice and a range of financial services, while discount brokers, such as Robinhood or E*TRADE, provide a more cost-effective option with fewer advisory services.
