Why is Munjal Showa falling/rising?

As of 01-Aug, Munjal Showa Ltd. is experiencing a decline in its stock price, currently at Rs 145.10, which reflects a decrease of Rs 3.45 or 2.32%. The stock has underperformed its sector by 1.1% today and has been on a downward trend for the last two days, accumulating a total decline of 4%. It opened significantly lower today, with a gap down of 3.74%, and reached an intraday low of Rs 139.15, marking a 6.33% drop. Over the past week, the stock has decreased by 3.01%, while its one-year performance shows a substantial decline of 20.30%. Despite a high dividend yield of 6.2%, the stock's profitability has decreased by 9.9% over the past year, contributing to its negative momentum.
In the broader market context, Munjal Showa's short-term performance has been worse than the benchmark Sensex, which has only fallen by 1.06% over the past week. While the stock has shown some resilience over longer periods, such as a 39.52% increase over three years, its recent performance indicates a struggle against both sector trends and overall market conditions. The company's low debt-to-equity ratio and attractive valuation at a price to book value of 0.9 suggest some underlying strength; however, the recent losses and declining profits overshadow these positives, leading to a cautious outlook among investors.
