NSE and BSE: Understanding India’s Two Major Stock Exchanges
India’s financial markets revolve around two powerful stock exchanges — the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE). These exchanges act as the backbone of India’s capital market, enabling millions of traders and investors to buy and sell shares, derivatives, and other securities every day.
While both exchanges serve the same purpose, they differ in history, technology, market share, trading volume, and company listings. This detailed guide explains those differences and helps investors understand which platform suits their needs better.
