Why is GMR Airports falling/rising?

As of 05-Sep, GMR Airports Ltd is experiencing a decline in its stock price, currently at 86.13, reflecting a decrease of 0.27 or 0.31%. The stock has been underperforming recently, with a consecutive fall over the last two days resulting in a total decline of 1.26%. Additionally, the stock's performance over the past month shows a significant drop of 7.19%, while its year-to-date return remains positive at 9.59%. Despite some positive financial indicators, such as a high return on capital employed and strong 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 Ltd's recent performance contrasts with the Sensex, which has increased by 1.13% over the past week. The stock's falling investor participation, evidenced by a 52.28% drop in delivery volume compared to the five-day average, further indicates a lack of confidence among investors. While institutional holdings are relatively high, suggesting some level of confidence from more sophisticated investors, the overall negative sentiment surrounding the company's debt and declining profits has overshadowed these positive aspects, leading to the current downward trend in stock price.
