Why is Hindustan Zinc falling/rising?

As of 05-Aug, Hindustan Zinc Ltd's stock price is currently at 421.05, reflecting a decrease of 0.25, or 0.06%. The stock has been trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 42.81% compared to the 5-day average. Over the past week, the stock has declined by 3.83%, and it has underperformed the market considerably, with a year-to-date return of -5.10% compared to the Sensex's gain of 3.29%. The company's low debt-to-equity ratio and high dividend yield of 4.5% are positive factors; however, the poor long-term growth, as evidenced by a -2.83% annual decline in operating profit over the last five years, and a recent drop in profit after tax by 14.2% have negatively impacted investor sentiment.
Broader market context indicates that while the broader market has generated a return of 0.50% over the past year, Hindustan Zinc has significantly underperformed with a return of -31.83%. This underperformance is compounded by a reduction in promoter confidence, as they have decreased their stake by 1.58% in the last quarter, which may signal a lack of confidence in the company's future prospects. The stock's high valuation relative to its peers, combined with disappointing quarterly results, has led to a perception of it being a strong sell, further contributing to its declining price.
