Why is Munjal Showa falling/rising?

As of 14-Jul, Munjal Showa Ltd. is experiencing a price increase, currently at Rs 154.60, reflecting a rise of 4.1 or 2.72%. The stock has shown strong performance recently, gaining 5.53% over the last two days and outperforming its sector by 1.33% today. It opened with a gain of 2.06% and reached an intraday high of Rs 156.9, indicating positive momentum. However, despite this short-term gain, the stock has generated a return of -2.80% over the past year, and its profits have declined by 9.9%. The company maintains a low Debt to Equity ratio and has a fair valuation with a Price to Book Value of 0.9, but it is trading at a premium compared to its peers' historical valuations.
In the broader market context, Munjal Showa's short-term return of +10.67% over the past week significantly outperforms the Sensex, which has declined by 1.42% in the same period. This indicates that the stock is gaining traction despite a generally unfavorable market environment. However, there are concerns regarding long-term growth, as evidenced by a decline in net sales and operating profit over the last five years. Additionally, institutional investor participation has decreased, which may impact future stock performance. Overall, while the stock is currently rising, underlying challenges could affect its sustainability.
