Why is Solar Industries falling/rising?

As of 24-Sep, Solar Industries India Ltd is experiencing a decline in its stock price, currently at 14,008.35, reflecting a decrease of 209.25 points or 1.47%. The stock has underperformed its sector by 0.98% today and has been on a downward trend for the last three days, accumulating a total drop of 4.56%. Over the past week, the stock has decreased by 5.46%, while it has shown a more positive performance year-to-date with a gain of 42.72%. Despite its strong long-term fundamentals, including a robust Return on Capital Employed (ROCE) of 30% and consistent growth in net sales and operating profit, the stock's high valuation and recent price movements indicate investor caution.
In the broader market context, the Sensex has only declined by 1.18% over the past week, suggesting that Solar Industries' recent performance is significantly worse than the overall market. The stock's liquidity remains adequate, with a delivery volume increase of 48.21% against the five-day average, indicating rising investor participation. However, the stock's current price is below several moving averages, which may signal bearish sentiment among investors. The company's high institutional holdings could provide some stability, but the expensive valuation and a PEG ratio of 2.8 may be contributing to the recent selling pressure, as investors reassess their positions in light of the stock's performance relative to its fundamentals.
