Why is GMR Airports falling/rising?

As of 09-Jul, GMR Airports Ltd is experiencing a rise in its stock price, currently at Rs 92.80, reflecting an increase of 1.57 (1.72%). The stock has shown strong performance recently, gaining 15.28% over the last 14 days and outperforming its sector by 1.73% today. Additionally, it has outperformed the benchmark Sensex with a 5.00% increase over the past week compared to the benchmark's 0.15%. However, despite these short-term gains, the company faces challenges such as a negative book value and high debt levels, which contribute to concerns about its long-term fundamental strength.
In the broader market context, GMR Airports Ltd has significantly outperformed the Sensex in the year-to-date period, with a return of 18.08% compared to the benchmark's 6.91%. This strong performance is notable given the company's recent struggles, including a decline in net sales growth and operating profit over the last five years. While the stock's recent gains may attract investor interest, the underlying financial issues, including a high debt-to-equity ratio and negative profit after tax, suggest that the stock remains risky compared to its historical valuations.
