Another major NSE and BSE difference is that BSE has a larger number of listed companies than NSE. BSE has over 5,500 listed companies, while NSE has around 1,600 listed companies. This makes BSE more diversified in terms of the range of companies that can be traded.
In case of liquidity, NSE is a clear winner, since volumes traded in NSE are much higher compared with BSE.
Can we buy in NSE and sell in BSE? Yes, you may buy stock from one exchange and sell it on another exchange after taking delivery of shares in your Demat account.
