BSE and NSE are the two stock exchanges in inda and in my idea have a similar stocks also. Then what is the difference between investing in NSE and BSE for same stocks.
For example What is the difference between SBI stock in both NSE and BSE. A quick look at the SBI chart from NSE and BSE looks similar
Since you've used the word "investor", I assume that you are referring to someone who buys and holds good stocks for a long time.
From such investor's point of view, differences are not too relevant.
For traders with average quantities (1 to 10000), liquidity is also not a major issue. You are trading for a better price and if you do it right, you can sell at little higher price on BSE or buy at lower price.
BSE lists more stocks than NSE and has concepts of Groups in addition to Industry Sectors.
Only nuisance in BSE is its numeric scrip codes. As long as you manage to resolve that, you will be fine.
