Why is Solar Industries falling/rising?

As of 14-Jul, Solar Industries India Ltd's stock price is currently at 15,271.00, reflecting a decrease of 121.2 points or 0.79%. The stock has been on a downward trend, experiencing a consecutive fall for the last 10 days, resulting in a total decline of 13.19% during this period. In the past week, the stock has underperformed significantly, with a return of -8.77%, while the Sensex has only declined by 1.42%. Despite this recent downturn, 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 is currently viewed as very expensive with a high Price to Book Value ratio of 31.5, which may be contributing to the recent price decline.
In the broader market context, while Solar Industries has shown impressive year-to-date returns of 55.59% and has outperformed the benchmark over the past year with a return of 27.42% compared to the Sensex's 2.15%, its short-term performance has been disappointing. The stock's recent struggles contrast sharply with its historical performance, as it has consistently generated strong returns over the last three years. The increase in investor participation, indicated by a rise in delivery volume, suggests that there is still interest in the stock, but the current market sentiment appears to be cautious, likely influenced by its recent price movements and valuation concerns.
