Nalco posts best-ever half-yearly results as net profit rises 54% in H1FY27

National Aluminium reported ₹11,143 crore and ₹3,837 crore, with movement of 54% and 33% attached to those lines. Those are the figures as filed — what moves the price is how they sit against what the market already expected, not their absolute size.

Against that, the stock is -3.2% on the day at ₹317.55, and has returned -13.9% over three months. It sits 28% below its 52-week high, which means a good deal of bad news was already in the price. The metals & mining sector has moved -9.5% over the same period, so National Aluminium is running 4.4 points behind its peers.

For National Aluminium, the question is how much of this is already reflected in the price and how much re-rates the metals & mining peer set alongside it.
