Why is GMR Airports falling/rising?

As of 01-Jul, GMR Airports Ltd is currently priced at 86.07, reflecting an increase of 0.69 or 0.81%. The stock has been on an upward trend, gaining for the last eight days and achieving a total return of 6.92% during this period. It has outperformed its sector by 0.57% today and is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. However, the stock faces challenges due to a negative book value and high debt levels, which contribute to its weak long-term fundamental strength. Despite a significant rise in the short term, the company has reported poor long-term growth, with net sales and operating profit increasing at rates of only 4.52% and 3.38%, respectively, over the last five years.
In the broader market context, GMR Airports has outperformed the Sensex in the past week, with a return of 3.46% compared to the benchmark's 2.00%. However, the stock has underperformed over the past year, generating a return of -11.84% while the broader market has seen a gain of 5.31%. This discrepancy highlights the stock's volatility and the risks associated with its negative book value and high debt-to-equity ratio. Despite recent gains, investor participation has declined, as indicated by a 15.31% drop in delivery volume, which may affect future price movements.
