Why is GMR Airports falling/rising?

As of 25-Jul, GMR Airports Ltd is experiencing a decline in its stock price, currently at Rs 89.90, which reflects a decrease of Rs 1.94 or 2.11%. The stock has underperformed its sector by 0.3% today and reached an intraday low of Rs 89.6. Over the past week, the stock has seen a drop of 4.65%, while it has performed better over the past month with a gain of 7.60%. However, the stock's long-term performance shows a decline of 4.47% over the past year, despite a significant increase of 151.47% over the last three years. The company has a negative book value and a weak long-term fundamental strength, with poor growth in net sales and operating profit over the last five years. Additionally, the high debt-to-equity ratio and recent flat results, including a substantial loss in profit after tax, contribute to the stock's downward pressure.
In the broader market context, the Sensex has only declined by 0.36% over the past week, indicating that GMR Airports Ltd's short-term performance is significantly worse than the benchmark. The stock's liquidity remains adequate for trading, but there has been a notable decrease in investor participation, with delivery volume falling by 39.65% against the five-day average. While the company has high institutional holdings, which typically indicate confidence from knowledgeable investors, the overall negative indicators regarding its financial health and performance suggest that investors may be cautious, leading to the stock's current decline.
