Why is Hindustan Zinc falling/rising?

As of 18-Aug, Hindustan Zinc Ltd's stock price is currently at 427.25, reflecting an increase of 0.75 or 0.18%. Despite this slight uptick, the stock has been experiencing a downward trend, having fallen by 1.02% over the last two days. The stock's performance over the past week shows a gain of 2.42%, contrasting with a decline of 1.92% over the past month. While the stock is currently trading above its 5-day moving average, it remains below its longer-term moving averages, indicating mixed performance. The company has a high dividend yield of 4.45%, which may attract some investors, but it also faces challenges such as a significant decline in quarterly profits and sales compared to previous averages, alongside a high percentage of pledged promoter shares, which can exert downward pressure on the stock price.
In the broader market context, Hindustan Zinc's recent performance has outpaced the benchmark Sensex in the short term, with a 1-week return of 2.42% compared to the Sensex's 0.83%. However, the stock has underperformed significantly over the longer term, with a 1-year decline of 17.83% against the Sensex's modest gain of 1.04%. This underperformance, coupled with poor long-term growth indicators such as a negative annual operating profit growth rate and a high valuation compared to peers, suggests that while there may be some short-term investor interest, the overall sentiment remains cautious due to the company's financial challenges and market dynamics.
