Hindustan Zinc shares experienced a significant decline, falling up to 10% over two days, with its stock price dropping to around Rs 588. This downturn is primarily attributed to a sharp fall in silver prices, which retreated from recent highs, impacting investor sentiment. The company's stock has seen a substantial rally in the past year, leading to profit-taking. Analysts suggest that while silver prices are crucial for Hindustan Zinc's profitability, the stock's recent surge may limit further immediate upside for new investors.
