Why is GMR Airports falling/rising?

As of 24-Sep, GMR Airports Ltd is currently priced at 89.04, reflecting a decrease of 1.53, or 1.69%. The stock has been underperforming recently, having fallen consecutively for the last three days, resulting in a total decline of 3.96%. Additionally, the stock's performance today has underperformed its sector by 1.39%. In terms of returns, the stock has seen a decline of 3.11% over the past week and 0.56% over the past month, while it has a year-to-date increase of 13.30%. Despite some positive indicators such as high institutional holdings and strong quarterly net sales growth, the company faces challenges due to a negative book value and high debt levels, which contribute to its weak long-term fundamental strength.
In the broader market context, GMR Airports' short-term performance has been notably weaker than the benchmark, with the Sensex declining only 1.18% over the past week. The stock's liquidity remains adequate for trading, but a significant drop in delivery volume indicates falling investor participation, which may further pressure the stock price. While the company has shown some positive financial metrics, the overarching concerns regarding its debt and negative book value create a risky investment environment, leading to its current downward price movement.
