On the other hand, stock exchange refers to a centralized marketplace where securities are bought and sold through a formalized and regulated process. Stock exchanges provide a platform for buyers and sellers to come together and trade securities in a transparent and efficient manner. The main difference between the two is the level of intermediation and the formalized structure of the trading process. **
