Why is Linde India falling/rising?

As of 18-Aug, Linde India Ltd. is experiencing a rise in its stock price, currently at Rs 6,366.85, reflecting an increase of Rs 143.85 or 2.31%. The stock has shown a positive performance today, aligning with the sector's growth, as the Industrial Gases & Fuels sector gained by 2.26%. However, despite today's uptick, the stock has underperformed over the past month with a decline of 5.10%. The stock's long-term growth prospects appear weak, with net sales growing at an annual rate of only 10.67% over the last five years. Additionally, the company has reported flat results recently, with the lowest ROCE and net sales figures, indicating potential challenges ahead.
In the broader market context, Linde India's short-term return of 2.44% over the past week outperforms the Sensex, which gained only 0.83% in the same period. However, the stock has significantly underperformed the market over the last year, with a return of -11.58% compared to the Sensex's positive return of 1.04%. This discrepancy highlights the stock's struggles despite recent gains. The company's high valuation, indicated by a Price to Book Value of 14.2, and a very high PEG ratio of 121.1 suggest that it is trading at a premium compared to its peers, which may deter investors looking for value. Overall, while there is a short-term rise in the stock price, the long-term outlook remains concerning.
