Why is Hindustan Zinc falling/rising?

As of 12-Aug, Hindustan Zinc Ltd's stock price is currently at 423.45, reflecting an increase of 6.3, or 1.51%. The stock has shown a trend reversal, gaining after two consecutive days of decline, and has outperformed its sector by 0.33% today. Despite this positive movement, the stock has underperformed in the longer term, with a year-to-date decline of 4.56% and a significant drop of 31.08% over the past year. The company has a high dividend yield of 4.55%, which may attract investors, but it also faces challenges such as a low debt-to-equity ratio and a poor long-term growth outlook, with operating profit declining at an annual rate of -2.83% over the last five years.
Broader market context indicates that while Hindustan Zinc has shown some resilience in the short term, the broader market, represented by the Sensex, has experienced a decline of 0.59% over the past week and 2.75% over the past month. The stock's performance has been notably weaker compared to the benchmark, with a one-year return of -31.08% against the Sensex's modest gain of 0.74%. Additionally, the high percentage of pledged promoter shares (92.26%) could exert downward pressure on the stock in a falling market, further complicating its recovery amidst broader market challenges.
