A stock exchange is a regulated marketplace where securities, including stocks, bonds, derivatives, and other financial instruments, are bought and sold. Stock exchanges facilitate capital formation by allowing companies to raise funds through public offerings while providing investors a platform to trade ownership stakes in publicly listed corporations.
The operation of a stock exchange is governed by legal and regulatory frameworks designed to ensure transparency, liquidity, and investor protection. It serves as a central hub for price discovery, risk management, and allocation of capital in modern economies.
