Why is Hindustan Zinc falling/rising?

As of 28-Aug, Hindustan Zinc Ltd's stock price is currently at 423.25, reflecting a decrease of 6.85, or 1.59%. The stock has been experiencing a downward trend, having fallen for the last two days with a total decline of 2.86% during this period. It is trading below all its moving averages, indicating weak momentum. Additionally, the stock has underperformed the market significantly over the past year, with a return of -17.20% compared to the benchmark's -2.08%. The company's recent financial performance has also raised concerns, as its profit after tax and net sales have both declined compared to previous quarters, and a high percentage of promoter shares are pledged, which can exert further downward pressure on the stock.
In the broader market context, Hindustan Zinc's short-term performance has been relatively better than the benchmark, with a 1-week return of -1.71% compared to the Sensex's -2.34%. However, the overall sentiment remains negative due to the company's poor long-term growth prospects, as indicated by a decline in operating profit over the last five years. Despite having a high dividend yield of 4.42%, the stock's valuation appears expensive compared to its peers, contributing to investor caution. The combination of falling investor participation and the company's financial struggles suggests that the stock is facing significant challenges in the current market environment.
