Why have shares of Vodafone Idea surged over 20% in a month?

Vodafone Idea's shares have jumped more than 20% over the last month, taking the stock's price to ₹12.01 on Tuesday. The surge is driven by investor optimism about a potential relief package for the company's long-standing adjusted gross revenue (AGR) dues of over ₹83,000 crore. The government reportedly plans to offer the telecom major an interest-free moratorium of 4-5 years.
