National Aluminium Company Ltd (Nalco) surged nearly 9% in Monday’s trade after posting robust Q2 FY26 results and declaring a ₹4 per-share interim dividend. Consolidated revenue rose 18% year-on-year, driven by higher alumina realizations and cost optimization measures. Profit margins expanded on improved operational efficiency at its Angul and Damanjodi units. The board’s interim payout boosted investor sentiment, extending the stock’s winning streak to a 15-month high. Analysts cite rising aluminium demand and stable input costs as supportive factors for sustained profitability in coming quarters.
