While Vodafone Idea crashed 34 per cent after the Supreme Court's dismissal of the AGR review petitions filed by telcos on its earlier Adjusted Gross Revenues (AGR) verdict, Bharti Airtel jumped 4 per cent and Reliance Industries gained nearly 2 per cent on Friday.

Bharti Infratel was the top loser on the NSE. Its stock price fell nearly 10 per cent on the AGR verdict.

JM Financials in a report said that it expects a governmental intervention soon to ensure that Vodafone Idea Limited (VIL) would not have to approach the NCLT next week due to payment deadline.

"While total sector AGR dues are pegged at Rs 920 billion to 1,400 billion, we believe exposure to VIL remains the most concerning from banks point of view due to insufficient cash balance and cash flows, and lack of borrowing capacity to fund these dues," JM Financials said.
