Why is Saint-Gob. Sekur falling/rising?

As of 24-Sep, Saint-Gobain Sekurit India Ltd is experiencing a slight increase in its stock price, currently at 118.00, reflecting a change of 0.7 or 0.6% upward. The stock has been gaining for the last two days, with a total return of 0.68% during this period. However, it has underperformed its sector by 3.11%. Over the past week, the stock has shown a modest gain of 1.20%, while it has declined by 2.12% over the last month and 9.23% year-to-date. Despite a healthy operating profit growth rate of 57.50% and positive quarterly results, the stock's valuation appears expensive with a Price to Book Value of 5, which may deter some investors. Additionally, the low participation from domestic mutual funds, holding only 0.01% of the company, suggests a lack of confidence at current price levels.
In the broader market context, the Sensex has decreased by 1.18% over the past week, indicating that the stock's recent performance is somewhat favorable compared to the benchmark. However, the stock's year-over-year performance shows a significant decline of 14.18%, while the Sensex has only fallen by 3.77% in the same period. This disparity highlights the stock's struggles relative to the overall market. The glass sector, in which the company operates, has gained by 3.71%, suggesting that the broader sector is performing well, yet Saint-Gobain Sekurit India Ltd's performance remains lackluster, potentially due to its high valuation and limited investor interest.
