It was created in 1996 and provides time series data from July 1990, onward.
At the last count, the BSE had about 4,700 listed firms, whereas the rival NSE had about 1,200.
Out of all the listed firms on the BSE, only about 500 firms constitute more than 90% of its market capitalization; the rest of the crowd consists of highly illiquid shares.
S., but upon closer inspection, you will find the same things you would expect from any promising market.
