Shares of Tata group companies, including Tata Consultancy Services Ltd (TCS), Tata Power Company Ltd, Tata Steel Ltd, Tata Motors Ltd, Trent Ltd, and Titan Company Ltd, would be in focus on Thursday morning following the death of Ratan Tata, 86, the chairman emeritus of Tata Sons.

Ratan Tata led the Tata Group's globalization push, which included high-profile acquisitions such as Tetley, Corus, Jaguar Land Rover, Brunner Mond, General Chemical Industrial Products, and Daewoo. He succeeded JRD Tata as Chairman of Tata Sons and Chairman of the Tata Trusts in March 1991. Tata Sons is the primary investment holding firm and promoter of Tata Enterprises. Philanthropic trusts own 66% of Tata Sons' equity share capital, which supports education, health, livelihood generation, and art & culture.

Ratan Tata resigned as Chairman of Tata Sons in December 2012, following 50 years with the Tata company, and was named Chairman Emeritus of Tata Sons.

In 2023-24, the combined sales of Tata firms exceeded $165 billion. These enterprises combined employed nearly ten lakh people. As of March 31, 2024, 26 publicly listed Tata firms had a combined market capitalization of more than $365 billion.

Natarajan Chandrasekaran, chairman of Tata Sons and Tata Group, stated in an evening statement: "It is with profound sadness that we bid farewell to Mr. Ratan Naval Tata." His immense achievements have shaped not only the Tata Group, but the very fabric of our country."

Ratan Tata had previously rejected worries about his health, telling the public that his hospitalization was for standard age-related examinations. But his untimely death has created a gap in the Indian economic environment that few can fill.

TRF, Voltas, Automobile Corporation of Goa Ltd, The Indian Hotels Company Ltd, and Tata Investment Corporation Ltd have all surged between 50 and 90 percent during the same time. Titan Company Ltd, Benares Hotels Ltd, Tata Technologies Ltd, Tata Elxsi Ltd, and Tata Teleservices (Maharashtra) Ltd are five group companies that have provided negative returns of 5-13% in 2024 thus far.
