Vedanta Aluminium shares surged after Emkay initiated coverage with a 'Buy' rating and a Rs 550 target, citing strong medium-term prospects. The brokerage anticipates a global aluminium deficit through 2028, driven by robust demand and supply constraints. Emkay believes structural cost reductions through backward integration will fuel earnings growth, positioning Vedanta Aluminium as a low-cost producer with a favourable risk-reward profile.
