Investing in top Indian business groups can provide steady, lower-risk growth or income, as these established companies have a proven track record. Currently, direct stock purchases are the primary method, but Tata Mutual Fund is seeking approval to launch a BSE Select Business Groups Index Fund, which will track the performance of the top 30 companies from seven major business groups in India. The fund will select stocks based on free-float market capitalization from the BSE 500 index.
