A stock exchange is a marketplace where stocks (shares of ownership in businesses) and other securities are bought and sold. It provides a platform for companies to raise capital by issuing shares to the public and for investors to trade these shares. Stock exchanges play a critical role in the financial ecosystem, offering transparency, liquidity, and regulation.
