Why is Hindustan Zinc falling/rising?

As of 11-Aug, Hindustan Zinc Ltd's stock price is currently at 417.15, reflecting a decrease of 3.5 points or 0.83%. The stock has been experiencing a downward trend, having fallen for the last two days with a total decline of 1.74% during this period. It is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish sentiment. Additionally, there has been a notable drop in investor participation, with delivery volume falling by 36% compared to the 5-day average. The company has a low debt-to-equity ratio of 0.04, but its long-term growth prospects appear poor, as evidenced by a decline in operating profit over the last five years and a significant drop in quarterly net sales and profit after tax. Furthermore, a high percentage of promoter shares are pledged, which can exert additional downward pressure on the stock price in a declining market.
In the broader market context, Hindustan Zinc's performance over the past year has significantly underperformed the benchmark, with a return of -29.89% compared to the Sensex's modest gain of 1.13%. Over the last week, the stock has decreased by 0.99%, while the Sensex has only fallen by 0.51%. This underperformance is compounded by the company's recent financial results, which show a decline in key metrics, further contributing to negative investor sentiment. Despite a high dividend yield of 4.52%, the overall market conditions and the company's financial struggles suggest that the stock's decline is likely to continue unless there are significant improvements in its operational performance or market conditions.
