Why is GMR Airports falling/rising?

As of 14-Jul, GMR Airports Ltd is experiencing a price increase, currently at Rs 91.50, reflecting a rise of 1.02 (1.13%). The stock has shown a positive trend today, gaining after two consecutive days of decline, and has outperformed its sector by 1.57%. Additionally, the stock has touched an intraday high of Rs 92.33. Over the past week, GMR Airports has returned +1.61%, significantly outperforming the Sensex, which has declined by -1.42%. However, it is important to note that the company has a negative book value, indicating weak long-term fundamental strength, and has reported poor growth in net sales and operating profit over the last five years.
Broader market context shows that while GMR Airports has performed well in the short term, with a year-to-date return of +16.43% compared to the Sensex's +5.27%, the stock's long-term performance has been less favorable, with a one-year return of -6.36%. The stock's liquidity remains adequate for trading, but a significant drop in delivery volume suggests falling investor participation. Despite the positive short-term movements, the company's high debt levels and negative profitability trends raise concerns about its long-term viability, which could impact future stock performance.
