Index Performance
The broader market provided a supportive backdrop: the BSE Sensex advanced 663.44 points, or 0.86%, over the week, while the Nifty50 gained 214.85 points, or 0.89%. The back-to-back weekly gains reflect continued domestic buying interest even as global cues remained mixed.
Top Gainers in Market Capitalisation
Bharti Airtel recorded the sharpest jump, with its market capitalisation climbing ₹36,529.21 crore to reach ₹11,63,877.30 crore. Bajaj Finance followed with an addition of ₹33,059.83 crore, taking its valuation to ₹6,43,141.36 crore.
ICICI Bank added ₹16,084.29 crore to close the week at a market cap of ₹10,11,695.03 crore.

HDFC Bank rose by ₹7,664.89 crore to ₹12,33,646.33 crore, while Hindustan Unilever added ₹6,461.38 crore, ending at ₹5,17,086.30 crore.
Companies That Lost Ground
Four of the top-10 firms saw their valuations erode during the week. Larsen & Toubro suffered the steepest decline, shedding ₹26,572.20 crore to close at ₹5,53,978.63 crore. Reliance Industries lost ₹18,945.56 crore, bringing its market cap to ₹17,64,981.36 crore.
State Bank of India (SBI) saw its valuation fall by ₹4,846.08 crore to ₹9,59,891.92 crore, while Tata Consultancy Services (TCS) shed ₹1,031.15 crore, ending the week at ₹7,57,175.27 crore.
Ranking of Top-10 Most-Valued Firms
Despite its weekly dip, Reliance Industries retained its position as India's most-valued listed company. The full top-10 ranking, in order, stands as: Reliance Industries, HDFC Bank, Bharti Airtel, ICICI Bank, State Bank of India, Tata Consultancy Services, Bajaj Finance, Larsen & Toubro, Life Insurance Corporation of India, and Hindustan Unilever.
With indices sustaining their upward momentum, market participants will be watching whether the breadth of gains widens further in the coming sessions.
Point of View
Meaning the rally is concentrated rather than broad. Meanwhile, Reliance Industries and Larsen & Toubro — two of the market's traditional anchors — both lost ground, a divergence that deserves more scrutiny than the aggregate figure suggests. If index-level optimism is not translating evenly into the top-10, the risk is that retail investors chasing index momentum miss the stock-level dispersion underneath.
