Why is GMR Airports falling/rising?

As of 18-Jul, GMR Airports Ltd is currently priced at 94.28, reflecting a decrease of 0.28 or 0.3%. Despite this recent decline, the stock has shown strong performance over the past week, with a return of 4.20%, and a notable 13.65% increase over the past month. The stock has outperformed its sector today by 0.35%, although it has experienced a trend reversal after four consecutive days of gains. Additionally, GMR Airports is trading above all its moving averages, and there has been a rise in investor participation, with delivery volume increasing by 13.62% compared to the five-day average. However, the company faces challenges, including a negative book value and high debt levels, which contribute to its weak long-term fundamental strength and a risky investment profile.
Broader market context indicates that while GMR Airports has outperformed the Sensex in the short term, with a year-to-date return of 19.96% compared to the Sensex's 4.63%, the stock's performance over the past year has been less favorable, with a return of -1.75%. The company's financial health is concerning, as evidenced by a significant drop in profit after tax and a high debt-to-equity ratio, which may deter long-term investors. The combination of strong short-term returns and underlying financial weaknesses creates a complex picture for GMR Airports, contributing to its current price movement.
