Why is Munjal Showa falling/rising?

As of 15-Jul, Munjal Showa Ltd. is experiencing a decline in its stock price, currently at 153.25, which reflects a decrease of 1.35 (-0.87%). Today's price summary indicates that the stock underperformed its sector by 2.53% and has fallen after two consecutive days of gains. Although it opened with a gain of 2.13% and reached an intraday high of Rs 157.9, the weighted average price showed more volume traded close to the low price. The stock has generated a return of -3.22% over the past year, with profits falling by 9.9%, and it is trading at a premium compared to its peers' average historical valuations. Additionally, the company has shown poor long-term growth, with net sales declining at an annual rate of -0.59% and operating profit decreasing by -32.24% over the last five years.
In the broader market context, Munjal Showa's short-term performance has been relatively strong, with a 10.73% increase over the past week, while the benchmark Sensex has decreased by 1.36%. However, the stock's year-to-date return of 5.04% lags behind the Sensex's 5.67%. The decline in institutional investor participation, with a decrease of -0.69% in their stake, raises concerns about the stock's future performance, as these investors typically have better resources to analyze company fundamentals. Overall, the combination of falling investor participation, poor long-term growth prospects, and a premium valuation compared to peers contributes to the stock's recent downward movement.
