Why is Man Industries falling/rising?

As of 09-Sep, Man Industries (India) Ltd is currently priced at 416.30, reflecting a decrease of 0.7 points or 0.17%. The stock has been underperforming recently, having fallen consecutively for the last two days, resulting in a total decline of 1.63%. Additionally, the stock's performance today has lagged behind its sector by 0.47%. Despite a strong long-term performance with a 368.81% increase over the past three years and a 27.23% rise year-to-date, recent quarterly results show a decline in net sales and profit after tax, which may be contributing to the current downward trend. Furthermore, a significant drop in delivery volume by 56.95% against the five-day average indicates falling investor participation, which could further pressure the stock price.
In the broader market context, while the Sensex has increased by 1.18% over the past week, Man Industries has outperformed the benchmark with a 7.16% gain in the same period. However, the stock's one-month performance shows a decline of 0.76%, contrasting with the Sensex's 1.56% increase, suggesting a weakening relative strength. The company's low debt-to-equity ratio and consistent returns over the last three years are positive factors, yet concerns about poor long-term growth and high valuation compared to peers may be causing investors to reassess their positions, contributing to the stock's recent decline.
