Why is GMR Airports falling/rising?

As of 23-Jul, GMR Airports Ltd is experiencing a decline in its stock price, currently at 91.35, which reflects a decrease of 0.54 or 0.59%. The stock has underperformed its sector by 0.83% today and has been on a consecutive downward trend for the last four days, resulting in a total decline of 3.39% during this period. Despite a positive performance over the last month with a return of 12.20%, the stock has shown a negative return of 2.91% over the past year. The company is facing challenges, including a negative book value and weak long-term fundamental strength, with net sales and operating profit growth rates of only 4.52% and 3.38%, respectively, over the last five years. Additionally, the stock's high debt-to-equity ratio and poor quarterly results, including a significant loss in profit after tax, contribute to its current negative sentiment.
In the broader market context, GMR Airports Ltd's recent performance contrasts with the Sensex, which has shown a slight increase of 0.11% over the past week. While the stock has outperformed the benchmark over a three-year period with a return of 159.52% compared to the Sensex's 47.54%, its recent struggles highlight a divergence in short-term performance. The falling investor participation, indicated by a 24.46% drop in delivery volume against the five-day average, further exacerbates the stock's challenges, suggesting a lack of confidence among investors in the company's future prospects.
