Reliance Industries Limited on Wednesday witnessed its stock hit a seven-year high, just a day after announcing the new tariff plans for Reliance Jio Prime. The Mukesh Ambani-led company’s stock rallied as much as 7.3% to Rs 1,158. This is RIL's highest intraday jump since May 16, 2014, when Narendra Modi-led Bharatiya Janata Party won the country's general elections.
