Why is Bimetal Bearings falling/rising?

As of 19-Sep, Bimetal Bearings Ltd. is experiencing a decline in its stock price, currently at Rs 643.70, which reflects a decrease of Rs 11.2 or 1.71%. The stock has underperformed its sector by 1.9% today, touching an intraday low of Rs 641.05. Over the past week, the stock has seen a decline of 1.73%, while it has shown a modest gain of 0.84% over the past month. Despite a strong performance in terms of operating cash flow and net sales reported in June, the stock has faced a significant drop of 17.32% over the past year, indicating challenges in maintaining investor confidence despite positive earnings growth.
In the broader market context, the Sensex has increased by 0.88% over the past week, contrasting with Bimetal Bearings' decline, which highlights the stock's underperformance relative to the market. The company's low debt-to-equity ratio and attractive valuation metrics, such as a price-to-book value of 1.1, suggest potential for recovery; however, the stock's year-to-date performance of -6.49% compared to the Sensex's gain of 5.74% reflects ongoing challenges. The rising investor participation, indicated by a significant increase in delivery volume, may provide some support, but the overall negative sentiment surrounding the stock continues to weigh heavily on its price movement.
