Why is Linde India falling/rising?

As of 16-Sep, Linde India Ltd. is experiencing a decline in its stock price, currently at 6,500.00, reflecting a decrease of 15.5 points or 0.24%. The stock has underperformed its sector by 0.32% today, with a notable drop in investor participation, as evidenced by a 45.88% decrease in delivery volume compared to the 5-day average. Despite this, the stock has shown positive returns over the past week and month, with increases of 0.84% and 4.69%, respectively. However, it has a significant year-over-year decline of 22.01%. The company maintains a low debt-to-equity ratio, which is a positive factor, but the recent underperformance and falling investor interest may be contributing to the current price movement.
In the broader market context, Linde India's short-term performance has lagged behind the Sensex, which has gained 1.58% over the past week, while Linde's return was only 0.84%. This underperformance relative to the benchmark may be influencing investor sentiment negatively. Additionally, while the stock has shown impressive long-term growth over three and five years, the recent decline in participation and the stock's inability to maintain momentum against the benchmark could be causing concern among investors, leading to the current downward price trend.
