The Bombay Stock Exchange, or BSE, is one of the two main stock exchanges in India and is widely described as Asia’s oldest, with roots going back to 1875. Its best-known index is the S&P BSE Sensex, which tracks 30 large companies and has been a barometer of the Indian market since 1986. The BSE lists companies on its main board and on its SME platform, which is meant for small and medium enterprises and follows its own eligibility and market-making rules. During an IPO, the BSE and the NSE both publish bidding data, so investors can see category-wise subscription figures through the issue, and the BSE issues the listing circular announcing the date on which a stock begins trading. Companies often list on both exchanges, though some choose one. The BSE website publishes offer documents, anchor investor details, allotment notices and corporate filings, and these are primary sources for any IPO analysis. IPO Bulletin uses the BSE’s disclosures and links to them from each IPO page, so readers can check the figures themselves.
Example: A company lists on both the BSE and the NSE. The BSE’s Sensex may later include the stock if it meets the index criteria, but a new listing is not automatically part of the index.
