Why is Hindustan Zinc falling/rising?

As of 26-Aug, Hindustan Zinc Ltd's stock price is currently at 430.10, reflecting a decrease of 5.6, or 1.29%. The stock's performance today is in line with the sector, although it is trading lower than its 50-day, 100-day, and 200-day moving averages. Despite a recent rise in investor participation, with delivery volume increasing by 75.53% against the 5-day average, the stock has underperformed over the past year, showing a return of -18.57% compared to the Sensex's -1.12%. The company has a low debt-to-equity ratio of 0.04, but its long-term growth prospects appear poor, with operating profit declining at an annual rate of -2.83% over the last five years. Additionally, the recent quarterly results show a significant drop in profit after tax and net sales, contributing to negative sentiment around the stock.
In the broader market context, while the stock has shown a slight positive return of 0.33% over the past week, it has still lagged behind the Sensex, which has decreased by 1.05% in the same period. The stock's performance over the year has been notably worse than the market, with a decline of -18.57% compared to the broader market's negative return of -3.87%. The high percentage of pledged promoter shares, at 92.26%, adds to the downward pressure in a falling market, further exacerbating the stock's challenges. Overall, the combination of poor financial performance, high valuations relative to peers, and significant pledged shares has contributed to the stock's recent decline.
