Why is Man Industries falling/rising?

As of 20-Aug, Man Industries (India) Ltd is experiencing a price increase, currently at 413.05, reflecting a rise of 9.55 or 2.37%. The stock has shown a positive performance today, outperforming its sector by 1.39%, and has gained consecutively over the last two days with a total return of 4.97%. Despite opening with a loss of 4.56%, the stock reached an intraday high of Rs 418.4. However, it has faced challenges, including a significant drop in delivery volume by 49.46% compared to the 5-day average. The company has a low debt-to-equity ratio of 0.08, but it is facing concerns regarding poor long-term growth, as evidenced by a decline in net sales and profit after tax.
In the broader market context, the stock has outperformed the Sensex in the short term, with a 1-week return of 3.26% compared to the benchmark's 1.64%. However, over the past month, Man Industries has underperformed with a return of -5.45% against the Sensex's slight gain of 0.12%. While the stock has shown impressive long-term growth over three and five years, recent quarterly results indicate a decline in net sales and profit, leading to concerns about its valuation, which is considered expensive relative to peers. This combination of short-term gains amidst long-term growth concerns contributes to the stock's current price movement.
