Eternal’s Nifty 50 Weight Surpasses TCS on Free Float
Eternal and TCS are both companies in India’s Nifty 50 stock index.
Eternal now takes up a slightly bigger share of the index than TCS.
That does not mean Eternal is a bigger company.
The index counts the shares investors can buy and trade, and Tata Sons owns a large part of TCS.
Eternal’s share price and expectations for future growth, especially at Blinkit, also affect its index weight.
TCS currently earns much more profit, according to the figures in the article.
Funds that copy the index therefore need to hold a little more Eternal and a little less TCS.
Investors may prefer Eternal’s growth prospects or TCS’s lower valuation and dividend, depending on their goals.
As of September 30, 2026, Eternal had a 2.29% Nifty 50 weight, compared with TCS at 2.08%.
The difference reflects free-float market capitalisation: Tata Sons owns about 72% of TCS, while more of Eternal’s shares are publicly investable.
TCS has a reported market capitalisation of about ₹7.5 lakh crore and quarterly profit of ₹13,420 crore; Eternal’s figures were about ₹3.1 lakh crore and ₹92 crore.
Eternal’s valuation reflects growth expectations, particularly for quick-commerce business Blinkit, while TCS is described as trading at a lower valuation and offering a dividend yield.
Nifty 50 funds tracking the index must hold relatively more Eternal; analysts say investors should also assess each company’s growth prospects, valuation and business risks.
