Why is GMR Airports falling/rising?

As of 07-Aug, GMR Airports Ltd is currently priced at 90.88, reflecting a decrease of 0.33, or 0.36%. The stock has been underperforming, having fallen for the last two days with a total decline of 2.07%. Despite a recent increase in investor participation, as indicated by an 82.96% rise in delivery volume, the stock's performance today has underperformed its sector by 0.51%. Over the past week, the stock has gained 0.90%, while it has shown a year-to-date increase of 15.64%. However, it has also experienced a year-over-year decline of 6.41%. Positive factors include strong quarterly results, such as the highest net sales and operating profit to interest ratio, along with high institutional holdings, which suggest confidence from larger investors. Conversely, the company faces challenges due to a negative book value, high debt levels, and weak long-term growth, which may contribute to the recent price decline.
In the broader market context, GMR Airports Ltd's short-term performance has been relatively better than the benchmark, as it has gained 0.90% over the past week compared to the Sensex's decline of 0.69%. However, the stock's year-over-year performance is concerning, as it has underperformed the Sensex, which has increased by 1.45% in the same period. The combination of recent price declines, high debt levels, and a negative book value indicates that while there are some positive indicators, the overall sentiment may be weighed down by fundamental weaknesses, leading to the current downward movement in the stock price.
