Why is GMR Airports falling/rising?

As of 06-Aug, GMR Airports Ltd is currently priced at 91.21, reflecting a decline of 1.59 points or 1.71%. Today's price summary indicates that the stock has underperformed its sector by 1.33% and has experienced a trend reversal after two consecutive days of gains, touching an intraday low of Rs 90.76. Despite a strong performance over the longer term, with a year-to-date return of 16.06%, the stock has faced challenges, including a negative book value and high debt levels, which contribute to its weak long-term fundamental strength. The recent positive results, such as the highest recorded net sales and return on capital employed, are overshadowed by concerns regarding poor long-term growth and declining profits.
In the broader market context, GMR Airports Ltd's short-term performance contrasts with the benchmark Sensex, which has declined by 1.15% over the past week while the stock itself has gained 1.62%. However, the stock's recent decline indicates a shift in investor sentiment, possibly influenced by its high debt-to-equity ratio and the risks associated with its negative book value. While institutional holdings remain strong, reflecting confidence from larger investors, the overall market conditions and the stock's recent performance suggest caution among retail investors, contributing to the current downward movement in its price.
