Why is Hindustan Zinc falling/rising?

As of 08-Aug, Hindustan Zinc Ltd's stock price is currently at 420.65, reflecting a decrease of 3.9 points or 0.92%. The stock's performance today is in line with the sector, although it is trading higher than its 5-day moving averages but lower than the 20-day, 50-day, 100-day, and 200-day moving averages. Notably, there has been a decline in investor participation, with delivery volume falling by 22% compared to the 5-day average. Over the past year, the stock has underperformed significantly, with a return of -29.63%, while its profits have risen by 26.6%. The company has a high dividend yield of 4.48%, but it also has a high percentage of pledged promoter shares at 92.26%, which can exert additional downward pressure on the stock price.
In the broader market context, Hindustan Zinc's short-term return of +1.23% over the past week contrasts with a decline of 0.92% in the Sensex, indicating some relative strength in the short term. However, the stock has underperformed the market over the last year, where the benchmark has only declined by -1.79%. The company's low debt-to-equity ratio and significant market capitalization suggest stability, but poor long-term growth prospects, as evidenced by a -2.83% annual rate of operating profit growth over the last five years, contribute to a negative outlook. The stock's premium valuation compared to peers and the recent drop in net sales and profit after tax further highlight the challenges it faces in the current market environment.
