Why is Solar Industries falling/rising?

As of 18-Jul, Solar Industries India Ltd is experiencing a decline in its stock price, currently at 14,900.00, reflecting a decrease of 274.0 points or 1.81%. The stock has underperformed its sector by 0.78% today and has been on a downward trend for the last three days, accumulating a total decline of 3.03%. Over the past week, the stock has decreased by 3.20%, while its performance over the last month shows a significant drop of 12.83%. Despite these short-term declines, the company has demonstrated strong long-term fundamentals, with a robust average Return on Capital Employed (ROCE) of 30.00% and consistent growth in net sales and operating profit. However, the stock's valuation appears expensive with a high Price to Book Value ratio of 30.7, which may be contributing to investor caution.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has only declined by 0.90% over the same week. This indicates that while the market is experiencing some downturn, Solar Industries is facing a more pronounced drop. The company's liquidity remains adequate, but a notable decrease in delivery volume suggests falling investor participation, which could further pressure the stock price. Despite its strong institutional holdings and consistent returns over the past three years, the recent price movements may reflect investor concerns over its high valuation relative to earnings growth, as indicated by the PEG ratio of 2.5.
