Indian equities head into Friday’s session carrying their strongest percentage gain since June after ICICI Bank Ltd, Reliance Industries Ltd, HDFC Bank Ltd and Bharti Airtel Ltd powered the Nifty 50 to a 22,997.35 close, leaving the index within sight of the 23,000 handle that strategists now treat as the session’s psychological pivot.

Thursday’s squeeze

The Nifty rose 1.66 percent on Thursday even as global technology shares sold off on artificial-intelligence valuation fears. The Sensex 30 gained 2.1 percent to 74,315.61. Traders said a jump in the Nifty put-call ratio to 1.65 from 1.01 pointed to aggressive short covering in index heavyweights after weeks of foreign selling.

Domestic institutional investors bought a net ₹3,319 crore of shares, while foreign portfolio investors sold a net ₹5,285 crore, according to exchange data cited by Livemint. On a gross basis, foreign funds still bought ₹12,735 crore, underscoring how net figures mask two-way books in a thin breadth rally.

Bank Nifty and the 55,500 floor

Nifty Bank closed above 55,500 after a 500-point advance led by large private banks, though Yes Bank Ltd weighed on the index when it failed to hold early gains. CNBC TV18 flagged 56,000 as immediate resistance and 55,500 as the level bulls want to cement as support going into a heavy banking results weekend.

Thursday’s rally also rode a fifth straight day of rupee appreciation—up 23 paise to 95.06 per dollar—and a 1.3 percent drop in Brent crude to $104.63, easing import-cost worries for oil marketing companies and inflation watchers at the Reserve Bank of India.

Friday’s setup

With the October 16 reporting fortnight now requiring banks to hold 99 percent of their daily cash reserve ratio average—up from 90 percent—treasury desks will watch whether liquidity tightness caps the follow-through. Earnings remain the other swing factor: fewer companies report on Friday than on “Super Saturday” for lenders, but Nestlé India’s strong volume print sets a consumer demand tone.

Strategists at CNBC TV18 said sustaining above 23,000 could open a path toward 23,200, while failure would put 22,650–22,600 back in play. Weak market breadth—more decliners than advancers on several recent sessions—means the index can rise without broad participation, a pattern foreign investors have punished in prior months.

Flows to watch

Options markets expire on 19 October, so gamma positioning around 23,000 could amplify moves into the close. Until foreign selling abates on a net basis, many desks treat this rally as tactical rather than structural, especially with Korea’s Kospi still nursing sharp tech losses that could spill into Asian sentiment.
