Why is Munjal Auto Inds falling/rising?

Despite a high dividend yield of 3.28% and a strong ability to service debt indicated by a low Debt to EBITDA ratio of 1.12 times, the stock has faced challenges, including a significant drop in investor participation, with delivery volume falling by 69.95% against the five-day average. The stock's returns over the past year have been notably poor, with a decline of 30.69%, coinciding with a 53.5% drop in profits.
In the broader market context, the Sensex has increased by 1.58% over the past week, contrasting sharply with Munjal Auto's decline. While the stock has shown healthy long-term growth with an annual operating profit increase of 53.68% and a very attractive valuation, it is currently trading at a discount compared to its peers. The stock's performance over the year and the recent drop in investor interest suggest that market sentiment may be weighing heavily on its price movement, despite the underlying fundamentals indicating potential for recovery.
