India's blue-chip universe took a ₹1.25 lakh crore hit in a single week, with RIL alone absorbing nearly ₹40,000 crore of that loss. The only bright spots were the big three banks — SBI, ICICI, and HDFC Bank — whose gains offered a slim buffer against an otherwise broad-based selloff.

Seven of India's top-10 most valued companies collectively shed ₹1.25 lakh crore in market capitalisation during the week ended 7 June, as broader indices came under pressure. The BSE Sensex fell 532.4 points (0.71%) over the same period, while the Nifty50 slipped 181.05 points (0.76%).
Reliance Industries Bears the Biggest Blow
Reliance Industries Limited (RIL) suffered the steepest valuation cut among the top-10, shedding ₹39,718 crore to close the week at a market capitalisation of ₹17,47,321.40 crore. Despite the sharp erosion, RIL retained its position as India's most valued listed company.
Tata Consultancy Services (TCS) was the second-biggest loser, with its market cap declining ₹20,134.66 crore to ₹7,95,346.09 crore. Bharti Airtel followed, losing ₹18,736.04 crore to settle at ₹10,96,150.49 crore.
Infrastructure and Insurance Names Also Under Pressure
Engineering conglomerate Larsen & Toubro saw its valuation erode by ₹16,880.2 crore, bringing it down to ₹5,43,956.44 crore. State-owned insurer Life Insurance Corporation of India (LIC) lost ₹14,610.74 crore, taking its market value to ₹5,05,873.32 crore.
In the financial space, Bajaj Finance shed ₹9,681.36 crore, while Hindustan Unilever Limited (HUL) lost ₹5,909.23 crore in market capitalisation over the week.
Banking Stocks Offer Partial Cushion
Not all large-caps were in retreat. State Bank of India (SBI) bucked the trend, adding ₹12,692.09 crore in valuation to reach ₹9,02,523.63 crore. ICICI Bank gained ₹4,484.86 crore, and HDFC Bank added ₹4,101.47 crore, lifting its market cap to ₹11,50,743.31 crore. The resilience of public and private sector banks provided a partial offset to the week's broader selloff.
Top-10 Ranking After the Week's Moves
Despite the mixed performance, the pecking order among India's most valued firms remained largely intact. Reliance Industries held the top spot, followed by HDFC Bank, Bharti Airtel, ICICI Bank, State Bank of India, TCS, Bajaj Finance, Larsen & Toubro, LIC, and Hindustan Unilever. With global macro uncertainty and domestic earnings season on the horizon, market watchers will be tracking whether the banking sector's relative strength can sustain the broader market through further volatility.
Point of View
718 crore drop alone accounts for nearly a third of the total damage — a structural vulnerability that index-heavy retail investors rarely price in. The banking counter-rally is encouraging but narrow; SBI and HDFC Bank gains do not signal broad market health, they signal sector rotation. Until global risk appetite stabilises and domestic earnings visibility improves, this pattern of concentrated losses in heavyweight non-banking names is likely to recur.
