Why is Linde India falling/rising?

As of 11-Sep, Linde India Ltd. is experiencing a decline in its stock price, currently at 6,446.40, which reflects a decrease of 11.7 points or 0.18%. The stock has underperformed its sector by 0.41% today, and while it is higher than the 20-day moving average, it remains below the 5-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has seen a slight decrease of 0.23%, but it has performed better over the past month with a gain of 3.72%. However, the stock has faced significant challenges over the past year, with a return of -15.62%, despite a positive year-to-date return of 7.50%. The company's low debt-to-equity ratio is a positive factor, but its poor long-term growth, as indicated by a low annual net sales growth rate and flat quarterly results, raises concerns.
In the broader market context, Linde India has underperformed compared to the benchmark Sensex, which has gained 1.03% over the past week and 1.17% over the past month. The stock's performance is particularly concerning given that it has generated a return of -15.62% over the last year, significantly worse than the BSE500's negative return of -2.29%. The company's valuation appears expensive relative to its peers, with a high price-to-book value and a PEG ratio of 122.6, suggesting that investors may be cautious about its future growth prospects. Overall, the combination of underwhelming financial performance, high valuation metrics, and recent underperformance relative to the market contributes to the stock's current decline.
