Why is Hindustan Zinc falling/rising?

As of 14-Aug, Hindustan Zinc Ltd's stock price is currently at 426.50, reflecting a decrease of 3.35, or 0.78%. The stock has shown a mixed performance recently, with a slight increase of 0.46% over the past week, but a decline of 2.27% over the past month and a significant drop of 25.56% over the last year. Today's price summary indicates that the stock has fallen after two consecutive days of gains, and while it is trading higher than its 5-day moving averages, it remains below the 20-day, 50-day, 100-day, and 200-day moving averages. The company has a high dividend yield of 4.42%, but it also faces challenges such as a poor long-term growth outlook, with operating profit declining at an annual rate of -2.83% over the last five years and a significant drop in quarterly net sales and profit after tax.
In the broader market context, Hindustan Zinc has underperformed compared to the benchmark, with a return of -25.56% over the past year against the BSE500's negative return of -0.57%. The company's high promoter share pledge (92.26%) adds additional downward pressure in a falling market, contributing to investor concerns. Despite a strong market position, with a market cap of Rs 1,81,625 cr and a low debt-to-equity ratio, the stock's valuation appears expensive relative to its peers, which may deter potential investors. Overall, the combination of declining financial metrics and high promoter pledges has led to a negative sentiment surrounding the stock, resulting in its recent price decline.
