Continuing governance and succession-related uncertainty within the Tata Group has significantly impacted investor sentiment, resulting in a loss of nearly ₹10 lakh crore in market value for listed Tata companies since the passing of Ratan Tata in October 2024.
Data from Prime Database indicates that the combined market capitalization of 21 listed Tata companies fell by 28.7 percent, from ₹34.2 lakh crore on September 30, 2024, to ₹24.4 lakh crore in March 2026—just nine days after Ratan Tata’s death. During this timeframe, indices associated with the Tata Group markedly underperformed compared to broader markets and other rival business groups.
The ‘Nifty India Corporate Group Index – Tata Group’ experienced a decline of over 32 percent from September 2024 to March 2026, while the ‘Nifty Tata Group 25 Cap Index’ decreased by 28 percent. In contrast, the Nifty 50 index saw a decline of approximately 13.5 percent during the same period, and corporate group indices for both Mahindra Group and Aditya Birla Group fell by only around 5 percent each, according to data from NSE Indices.
Foreign Portfolio Investors (FPIs) have decreased their stakes in various Tata companies, most notably in high-growth businesses that had previously enjoyed significant valuation increases during the post-Covid pandemic rally. This decline in foreign ownership aligns with significant erosion in market capitalization across several Tata companies. For example, Tata Motors Passenger Vehicles saw its market cap plummet nearly 70 percent since September 2024, while Tejas Networks lost over 66 percent of its value. Other firms, including Tata Consultancy Services, Tata Chemicals, Trent, Tata Technologies, and Tata Elxsi, also faced market-cap declines of around 40 percent or more. Conversely, Tata Steel’s market capitalization increased by nearly 14 percent to ₹2.4 lakh crore as of March 2026.
Market participants note that this divergence indicates that investors have become increasingly selective within the Tata ecosystem, especially amid heightened focus on governance, succession planning, and leadership continuity within the group.
Growing Tussle
The Tata Trusts, which controls just over 66 percent of the Group’s holding company, Tata Sons, is currently facing internal conflict among its trustees over critical issues, including the potential listing of Tata Sons and the selection of board nominees. Additionally, there is uncertainty surrounding N Chandrasekaran’s potential reappointment as chairman. This internal strife has been exacerbated by complaints of alleged violations of the Maharashtra Public Trusts Act, prompting the postponement of a key trustees meeting twice.
“Since Ratan Tata’s death, they have taken considerable time to address the situation, but they are implementing significant steps to improve the public perception of the Group,” stated Arun Kejriwal, founder of Kejriwal Research and Investment Services.
He added, “Investors generally shy away from controversy or uncertainty. In situations where there is turmoil, they tend to withdraw.”
A fund manager, opting for anonymity, commented, “The market is essentially incorporating uncertainty at the holding-company level, despite the operational businesses being fundamentally sound.”
Analysts have pointed out that global risk aversion and corrections in high-valuation stocks have exacerbated sentiment across markets in recent months. Nevertheless, the pronounced underperformance of Tata Group companies began before the latest waves of global volatility.
“Markets can tolerate weaker quarterly performances, but they struggle with uncertainty surrounding leadership and structural issues. That’s when investors assign a higher risk premium,” remarked a senior market participant closely monitoring the Tata Group.
