Why is GMR Airports falling/rising?

As of 23-Sep, GMR Airports Ltd is experiencing a decline in its stock price, currently at 90.57, reflecting a decrease of 0.6 or 0.66%. The stock has underperformed its sector today, with a consecutive fall over the last two days resulting in a total decline of 2.31%. Although the stock has shown positive performance over the longer term with a year-to-date increase of 15.24% and a remarkable 322.24% rise over the past five years, it has also faced challenges, including a negative book value and high debt levels, which contribute to its weak long-term fundamental strength. Additionally, the stock's delivery volume has significantly decreased, indicating falling investor participation, which may further pressure the stock price.
In the broader market context, GMR Airports' short-term performance has been notably weaker compared to the benchmark Sensex, which has only declined by 0.34% over the past week while GMR Airports has fallen by 2.46%. This underperformance is compounded by the company's high debt-to-equity ratio and a recent drop in net sales growth, which has raised concerns among investors. Despite having strong institutional holdings that have increased, the overall sentiment remains cautious due to the company's financial challenges, leading to a more bearish outlook in the short term.
