Why is Hindustan Zinc falling/rising?

As of 20-Aug, Hindustan Zinc Ltd's stock price is currently at 429.90, reflecting an increase of 1.2 (0.28%). The stock has been gaining for the last three days, with a total return of 0.8% during this period. It is performing in line with its sector, and the delivery volume has seen a rise of 12.14% compared to the five-day average, indicating increased investor participation. However, the stock's performance over the past month and year has been less favorable, with declines of 1.31% and 16.08%, respectively. Despite a high dividend yield of 4.43% and a low debt-to-equity ratio of 0.04, the company has faced challenges, including a significant drop in quarterly profits and sales, which may contribute to investor caution.
In the broader market context, the stock has underperformed relative to the benchmark, with the Sensex gaining 1.64% over the past week while Hindustan Zinc's return was nearly flat at 0.01%. Over the past year, the stock's decline of 16.08% starkly contrasts with the Sensex's modest gain of 1.31%. This underperformance, coupled with high promoter share pledges and poor long-term growth prospects, suggests that while there may be short-term gains, the overall sentiment towards Hindustan Zinc remains cautious amidst broader market conditions.
