Why is GMR Airports falling/rising?

As of 15-Jul, GMR Airports Ltd is currently priced at 91.97, reflecting an increase of 0.47 or 0.51%. The stock has been gaining for the last two days, with a total return of 1.65% during this period. It is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a positive short-term trend. However, there are concerns regarding falling investor participation, as the delivery volume has decreased by 12.74% compared to the 5-day average. Additionally, the company has a negative book value and weak long-term fundamentals, with poor growth rates in net sales and operating profit over the last five years, which could be contributing to cautious investor sentiment.
In the broader market context, GMR Airports has outperformed the benchmark Sensex in the short term, with a 1-week return of +0.81% compared to the Sensex's -1.36%. Despite this positive short-term performance, the stock has generated a negative return of -6.25% over the past year, while the Sensex has increased by 2.36%. This disparity highlights the stock's volatility and the risks associated with its high debt levels and negative book value, which may deter long-term investors despite recent gains.
