Why is Hindustan Zinc falling/rising?

As of 10-Jul, Hindustan Zinc Ltd is currently priced at 422.70, reflecting a decrease of 2.35, or 0.55%. The stock has been on a downward trend, having lost value for the last nine consecutive days, resulting in a total decline of 6.29% during this period. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish sentiment. Despite a high dividend yield of 4.47% and positive quarterly results, including record net sales and operating profit, the stock's long-term growth prospects appear poor, with an annual operating profit growth rate of only 1.09% over the last five years. Furthermore, a significant 93.5% of promoter shares are pledged, which can exert additional downward pressure in a declining market.
In the broader market context, Hindustan Zinc's performance has been notably weak compared to the Sensex, with a 1-week return of -5.11% against a minimal decline of 0.06% for the benchmark. Over the past year, the stock has generated a return of -35.98%, significantly underperforming the broader market, which has seen a 4.09% increase. This underperformance is compounded by the company's expensive valuation metrics, such as a high enterprise value to capital employed ratio, which further diminishes investor confidence. Overall, the combination of poor short-term performance, high promoter share pledging, and lackluster long-term growth prospects contributes to the stock's current decline.
