Shares of Tata Group companies soared up to 10% on Thursday, led by significant gains in Tata Chemicals and Tata Teleservices. This surge followed the passing of Ratan Tata, the revered Chairman Emeritus, who died at 86. Analysts noted that investors could pay tribute to Ratan Tata’s remarkable legacy by acquiring stocks of major Tata firms such as TCS, Tata Motors, Tata Steel, and Tata Consumer.
