Mumbai’s benchmark indices tore through resistance levels on Thursday. The BSE Sensex rocketed 2,008 points to finish at 79,310, while the NSE Nifty 50 surged 576 points to 24,536 in a relentless session of broad-market accumulation. The charge sealed a six-day winning run—the longest unbroken streak on Dalal Street since November 2025. Total market capitalization of BSE-listed firms crossed the ₹500 lakh crore threshold for the first time in history, hoisting the aggregate valuation of the domestic market back above $5 trillion after adding more than ₹8 lakh crore in a single day. Over the six-session advance, market capitalization expanded by nearly ₹30 lakh crore.
Bulls had one overwhelming tailwind: energy. Brent crude plunged 19% this week, printing its sharpest weekly price collapse since April 2020. That freefall radically altered the input-cost equation for import-heavy domestic industries, unleashing aggressive buying across fuel-sensitive sectors. InterGlobe Aviation leaped nearly 6% as jet fuel cost pressures evaporated, while paint makers and tyre fabricators saw immediate bids. Asian Paints joined the leaders on the Sensex board.
Lenders shouldered the heaviest lift. The Nifty Bank index surged 1,860 points to close at 57,774—its steepest single-day points advance since April 2026. Together, ICICI Bank and HDFC Bank alone delivered more than 200 points of the Nifty's total climb. Non-bank lenders followed in lockstep. Bajaj Finance and Shriram Finance dominated the high-beta volume table, absorbing persistent cash-market flows through the afternoon trade.
Then came the automakers. Commercial vehicle operators and car manufacturers rallied on the dual catalyst of tumbling fuel costs and quarterly earnings receipts. Ashok Leyland jumped 10%, breaking away from its previous ranges. Mahindra & Mahindra gained over 5% after its second-quarter financial numbers met Street expectations, anchoring an auto basket that saw sustained accumulation into the close.
Yet this was not an indiscriminate tide. The session produced severe corporate dispersion, rewarding clean balance sheets and punishing quarterly execution failures without mercy. Tonbo Imaging locked a 20% upper circuit after swinging from a year-ago net loss into a quarterly profit, while auto-component supplier Uno Minda surged over 11% on earnings strength.
The retribution elsewhere was swift. PI Industries crashed more than 19% after quarterly figures disappointed institutional desks. Cummins India sank 14% after missing revenue and margin estimates, while CG Power shed 5% following a Chhatrapati Sambhajinagar unit closure directive from the Maharashtra Pollution Control Board. State-run upstream producers also bucked the rally; Oil and Natural Gas Corporation slumped as crude realisations dropped, dragging NTPC, Coal India, and Hindustan Aeronautics into negative territory.
With the Nifty now pacing its strongest weekly gain since January 2021, trading desks head into Friday's closing session watching whether banking liquidity can defend the 24,500 base.
