Why is Hindustan Zinc falling/rising?

As of 25-Sep, Hindustan Zinc Ltd is experiencing a price increase, currently at Rs 466.55, which reflects a rise of Rs 13.65 or 3.01%. The stock has shown strong performance today, touching an intraday high of Rs 468.55, and is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has gained 2.56%, and in the last month, it has risen by 7.08%, significantly outperforming the Sensex, which has declined by 2.23% over the same period. However, there are concerns regarding falling investor participation, as the delivery volume has decreased by 17.16% compared to the 5-day average. Additionally, while the company has a low debt-to-equity ratio and is a leader in its sector, it faces challenges such as poor long-term growth and a high percentage of pledged promoter shares, which could exert downward pressure on the stock.
In the broader market context, Hindustan Zinc's recent performance stands in stark contrast to the benchmark Sensex, which has seen a decline of 2.23% over the past week. The stock's ability to rise while the broader market is falling indicates a relative strength, likely supported by sector-specific gains, as the Metal - Non Ferrous sector has increased by 3.03%. Despite the positive short-term returns, the stock's long-term outlook is clouded by declining operating profits and a high valuation compared to peers, which may affect investor sentiment moving forward.
