The real re-rating will happen in the PV vehicle space," he said.Tata Motors Demerger: Five Key Details Investors Should KnowHere's What Brokerages Have To SayJPMorganJPMorgan has maintained an 'overweight' rating on the stock with a target price of Rs 1,000 apiece, implying an upside of 1.29%.The research firm anticipates better-than-expected margin and free-cash-flow delivery at Jaguar Land Rover.Global luxury OEMs are prioritising profitability over volumes, which should benefit Jaguar Land Rover as well.Tata Motor's market share in Indian PVs has been resilient despite competitor launches.
