Why is GMR Airports falling/rising?

As of 01-Aug, GMR Airports Ltd is experiencing a decline in its stock price, currently at 89.29, reflecting a decrease of 0.78 or 0.87%. The stock's performance today is in line with the sector, and it is trading above its 50-day, 100-day, and 200-day moving averages, but below its 5-day and 20-day moving averages. Notably, there has been a rise in investor participation, with delivery volume increasing by 43.41% against the 5-day average. Over the past week, the stock has decreased by 0.68%, while it has shown a positive return of 3.74% over the past month. However, the stock has a negative book value and a high debt-to-equity ratio, indicating weak long-term fundamental strength, which may be contributing to its recent price movement.
In the broader market context, the Sensex has declined by 1.06% over the past week, suggesting that GMR Airports' performance is somewhat better than the benchmark. Despite the stock's year-to-date return of 13.61% compared to the Sensex's 3.15%, the stock has underperformed over the past year with a return of -11.99%, while the Sensex has only fallen by 1.55%. The company's high institutional holdings at 20.19% may provide some stability, as these investors typically have better resources for analyzing fundamentals. However, the overall negative sentiment surrounding the company's long-term growth prospects, as indicated by its declining profits and high debt levels, likely weighs on investor confidence and contributes to the stock's current downward trend.
