The Bombay Stock Exchange Limited (previously known as The Stock Exchange, Mumbai and generally called The Bombay Stock Exchange, or BSE) is the oldest stock exchange in Asia. It is situated at Dalal Street in the city of Mumbai in India.

The Bombay Stock Exchange was set up in 1875. There are approximately 4,800 Indian companies listed with the stock exchange. This exchange has a significant trading volume. As calculated in July 2007, the equity market capitalization of the companies listed on the BSE was US $ 1.005 trillion. The BSE SENSEX (SENSitive indEX), also known as the "BSE 30", is a widely used market index in India and Asia. The Singapore Exchange (SGX) has already made a strategic investment in Bombay Stock Exchange (5%) for US$42.7m.

The Bombay Stock Exchange SENSEX (also known as the BSE 30 index) is a value-weighted parameter composed of a total of thirty scripts, with the base figuring April 1979 = 100. The group of companies that constitute the index has been changed only a few times in the last twenty years. These companies make up around one-fifth of the market capitalization of the BSE.

Apart from the BSE SENSEX, which is the most accepted stock index in India, BSE uses other stock indicators as well. These are BSE 500, BSE 100, BSE 200, BSE PSU, BSE MIDCAP, BSE SMLCAP, BSE BANKEX, BSE Teck, BSE Auto, BSE Pharma, BSE Fast Moving Consumer Goods, BSE Metal, BSE Metal and BSE Broadcast. The BSE Broadcast is a large timepiece on the wall of the BSE, which constantly exhibits the most recent stock quotes from the market. It is also displayed on one of the foremost business-news channels in India -- NDTV Profit.
