If you had invested in the BSE Sensex in 1991 – at say Rs. 1000, it would be worth Rs. 28,000 in February 2017 and 20,000 till 2013 alone. The way the market goes up and never lets you down. The BSE (Sensex) and NSE Nifty has allowed investors to make ample money and that too making returns and profits tax free when invested for more than a year.
