Why is GMR Airports falling/rising?

As of 12-Aug, GMR Airports Ltd is currently priced at 88.50, reflecting a decrease of 0.65, or 0.73%. The stock has underperformed its sector today by 0.6%, and its delivery volume has significantly dropped by 80.18% compared to the 5-day average, indicating falling investor participation. Although the stock has shown strong performance over the long term with a 3-year return of 156.52% and a 5-year return of 313.55%, it has faced challenges recently, including a 1-week decline of 4.63% and a 1-year drop of 9.69%. The company has a negative book value and high debt levels, which contribute to its weak long-term fundamental strength, despite positive quarterly results such as the highest net sales and return on capital employed.
In the broader market context, GMR Airports Ltd's recent performance contrasts with the Sensex, which has only declined by 0.59% over the past week. While the stock has outperformed the benchmark year-to-date with a return of 12.61% compared to the Sensex's 2.68%, the negative trends in short-term performance and investor participation suggest a cautious outlook. The high institutional holdings may provide some stability, but the overall sentiment remains affected by the company's high debt and declining profits, which have fallen by 28.9% over the past year.
