Why is GMR Airports falling/rising?

As of 18-Sep, GMR Airports Ltd is currently priced at 91.71, reflecting a decline of 0.19 or 0.21%. The stock has been experiencing a downward trend, having lost 1.23% over the last two days. Despite this recent decline, the stock has shown positive performance over the past week, with a return of 4.79%, and a year-to-date increase of 16.69%. However, the stock's delivery volume has significantly decreased by 84.47% compared to the 5-day average, indicating falling investor participation. While the company has reported strong financial results, including the highest net sales and return on capital employed in the last quarter, it also faces challenges such as a negative book value and high debt levels, which contribute to its perceived riskiness.
In the broader market context, GMR Airports' short-term performance has outpaced the benchmark Sensex, which has gained 1.80% over the past week. However, the stock's longer-term performance shows a decline of 2.44% over the past year, contrasting with the Sensex's slight increase of 0.08%. The high institutional holdings at 20.19% suggest confidence from larger investors, but the company's weak long-term fundamentals and high debt-to-equity ratio raise concerns about its sustainability. Overall, while the stock has had strong short-term returns, the recent price decline reflects investor caution amid underlying financial challenges.
