Reliance Industries Ltd's stock could climb to Rs 1,800 a share, an upside of about 55 percent from Friday’s close, according to Deven Choksey, managing director of DRChoksey Finserv. He sees gains from strong refining margins in the oil-to-chemicals (O2C) business and the value of Reliance’s stake in listed Jio Platforms, and said he may raise his target price. Speaking to CNBC Awaaz, Choksey said his target price of around Rs 1,800 per share could be raised further.
