Why is Hindustan Zinc falling/rising?

As of 29-Aug, Hindustan Zinc Ltd's stock price is currently at 419.20, reflecting a decline of 4.05 points or 0.96%. The stock has been underperforming, having lost 3.79% over the last three days and is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Additionally, the delivery volume has decreased significantly, falling by 39.98% compared to the 5-day average, indicating reduced investor participation. Despite a high dividend yield of 4.49%, the company's financial performance has raised concerns, with a decline in both PAT and net sales compared to previous quarters, contributing to a negative sentiment around the stock. Furthermore, the high percentage of pledged promoter shares (92.26%) adds to the downward pressure in a falling market.
In the broader market context, Hindustan Zinc's short-term performance has been relatively better than the benchmark, with a 1-week return of -1.36% compared to the Sensex's -1.84%. However, the stock has underperformed significantly over the longer term, with a 1-year return of -15.57% against the Sensex's -2.83%. This underperformance, coupled with poor long-term growth indicators such as a -2.83% annual operating profit growth over the last five years, has led to a cautious outlook among investors. The company's high valuation metrics, including a PEG ratio of 0.7, further complicate its attractiveness, especially in light of its recent financial struggles.
