Regulators & SEBI
Understanding India's stock market regulator SEBI, its role, the major stock exchanges BSE and NSE, and how market participants are regulated.
What Is the Stock Market?
A stock market is a regulated marketplace where buyers and sellers come together to trade shares (also called equities) of publicly listed companies. Think of it as an organised platform — much like an auction house — where the price of each share is determined by supply and demand in real time.
In India, the stock market is overseen by a regulatory body that ensures fairness, transparency, and investor protection. Companies list their shares on a stock exchange, and investors can buy or sell those shares through registered intermediaries called stockbrokers.
India's Major Stock Exchanges
India has two primary stock exchanges where the vast majority of equity trading takes place.
