Why is Solar Industries falling/rising?

As of 17-Jul, Solar Industries India Ltd is experiencing a decline in its stock price, currently at 15,174.00, which reflects a decrease of 36.0 points or 0.24%. The stock has underperformed its sector by 0.49% today and has been on a consecutive downward trend for the last two days, accumulating a total decline of 1.25%. Over the past week, the stock has decreased by 4.47%, while it has shown a significant year-to-date increase of 54.60%. Despite strong long-term fundamentals, including a high Return on Capital Employed (ROCE) of 30.00% and consistent positive results over the last four quarters, the stock's recent performance is hampered by falling investor participation, as evidenced by a 51.71% drop in delivery volume compared to the five-day average.
In the broader market context, the stock's short-term performance contrasts with the benchmark, as it has underperformed the Sensex, which has only declined by 1.12% over the same week. While Solar Industries has shown impressive long-term growth with a 474.74% increase over the past three years, the current market sentiment appears cautious, likely influenced by its high valuation metrics, such as a Price to Book Value of 31.3, and a PEG ratio of 2.5, indicating that the stock may be perceived as expensive relative to its earnings growth. This combination of declining short-term performance and high valuation concerns may be contributing to the stock's recent downward movement.
