Why is Hindustan Zinc falling/rising?

As of 19-Aug, Hindustan Zinc Ltd's stock price is currently at 428.70, reflecting an increase of 1.45 (0.34%). The stock has shown a positive movement recently, gaining for the last two days with a total return of 0.52% during this period. However, over the past month, the stock has decreased by 1.58%, and it has underperformed significantly on a year-to-date basis with a decline of 3.38%. While the stock's performance today is in line with the sector, it is important to note that the company has a low Debt to Equity ratio, which is favorable, but it also faces challenges such as a poor long-term growth outlook and a significant percentage of promoter shares being pledged, which can exert downward pressure on the stock price.
In the broader market context, the stock's short-term return of +1.24% over the past week is lower than the benchmark Sensex, which has increased by 1.76%. This underperformance is indicative of the stock's struggles, especially given its -13.52% return over the past year compared to the Sensex's +1.52%. The market has been relatively stable, but Hindustan Zinc's significant decline in profits and sales in recent quarters, alongside its high valuation compared to peers, suggests that investor sentiment may be cautious. Overall, despite some positive indicators such as rising investor participation and a high dividend yield, the stock's long-term challenges and recent performance relative to the market contribute to its current price movement.
