Why is GMR Airports falling/rising?

As of 18-Aug, GMR Airports Ltd is currently priced at 90.26, reflecting a decrease of 0.52 or 0.57%. The stock has experienced a trend reversal, falling after two consecutive days of gains. It is performing in line with its sector today, but the delivery volume has decreased significantly by 38.18% compared to the 5-day average, indicating a decline in investor participation. Despite positive results in June, including the highest return on capital employed and net sales for the quarter, the company faces challenges such as a negative book value and high debt levels, which contribute to its weak long-term fundamental strength.
In the broader market context, GMR Airports Ltd has outperformed the Sensex over the past week, with a return of 1.25% compared to the benchmark's 0.83%. However, over the past month, the stock has declined by 4.26%, while the Sensex has only fallen by 0.59%. The high institutional holdings at 20.19% suggest that knowledgeable investors are backing the company, but the overall negative sentiment due to its poor long-term growth and high debt levels may be weighing on the stock's performance.
