Sushil Choksey, director at Indus Equity Advisors, says Reliance Industries' core business would be generating minimum of 20 per cent growth year on year. This will help the company bear the cost of its Jio venture in the initial years, he adds. Mr Choksey expects RIL shares to rise to Rs 1,300 level in 6 months and Rs 2,000 in 18 months.
