Nifty's Third Straight Losing Week as a New Closing Bell Draws the Blame — Even as Oil Tumbles From $94
Nifty closed at 24,175.65 on Friday, down about 0.3% for the week and its third straight weekly decline — the longest such run in five months. What made this week different was the excuse: alongside the usual Fed jitters, traders and Reuters alike pointed a finger at SEBI's new Closing Auction Session (CAS), the closing-price mechanism that's been live for less than a month and is still unsettling nerves around expiry. The offsetting story was oil, which gave back nearly all of last week's spike — Brent fell more than 5% to around $89 as the Iran standoff cooled from a supply threat into more of a sanctions stand-off. Meanwhile in Wyoming, Kevin Warsh delivered his first Jackson Hole speech as Fed chair, warning that inflation's "underlying trends" haven't meaningfully improved.
−0.3% — third straight losing week
Down over 5% for the week, from near $94
Strengthened 6 paise on Friday
Pulled back from this week's multi-month highs
The week never found a direction, chopping in a tight ~244-point band between 24,090 and 24,335 across five sessions with a different sector in the driver's seat almost every day: PSU banks and defence sold off Monday ahead of a new US sanctions push on Iran, pharma and healthcare rescued Tuesday's expiry session, IT and FMCG dragged Wednesday, metals and cement pulled the index below 24,100 on Thursday, and IT reversed course entirely on Friday to claw back some of the damage. Underneath the swings, Iran and Oman struck a revenue-sharing deal over the Strait of Hormuz and Gulf oil exports climbed back toward two-thirds of pre-war levels, which is what let crude fall as sharply as it did. Institutional flows stayed one-directional even as the index wasn't: FIIs sold on both Thursday and Friday, while DIIs kept absorbing that selling with net buying on the same two days, extending a pattern that's now held for most of 2026.
IT's Friday Rescue, and a Week Where the US Outran India
A look beyond the index level — at individual stocks, and at the rest of the world
IT stocks were the week's standout story, but only on the final day. Tata Consultancy Services (TCS) jumped over 4% on Friday, dragging Tech Mahindra, Infosys, HCL Tech and Wipro up alongside it, as Nvidia's strong quarterly results and an upbeat guidance raise from US software major Salesforce reassured investors about IT services demand. Earlier in the week the same sector had been a drag, falling on Wednesday alongside FMCG and auto stocks as traders stayed cautious ahead of Nvidia's earnings and fresh US inflation data. On the losing side, PSU banks and defence names sold off hard on Monday as investors turned cautious ahead of the US Treasury Secretary's press conference on new Iran sanctions, while metal, cement and PSU banking names — including Hindalco, HDFC Bank and Mahindra & Mahindra — led Thursday's slide as the week's second straight losing session took Nifty below 24,100.
| Stock | Move | Why |
|---|---|---|
| TCS, Tech Mahindra, Infosys | +3% to +4% (Fri) | Nvidia's earnings, Salesforce's guidance raise lift Indian IT sentiment |
| Vishal Mega Mart | +9.7% (Mon) | CEO's five-year reappointment announced |
| Hindalco, HDFC Bank, M&M | Thu's top losers | Metal, PSU bank and cement stocks dragged the index below 24,100 |
| SBI, LIC, Adani Ports | Mon's laggards | PSU bank and defence sell-off ahead of new Iran sanctions |
Zooming out, Nifty's mild weekly dip actually left India trailing most global peers for once. Wall Street snapped its own losing run, helped by falling Treasury yields early in the week and a market that mostly took Warsh's Friday tone in stride, while Asian markets traded without a clear common direction through the week.
| Index | Weekly Change | Note |
|---|---|---|

| S&P 500 (US) | ~+0.5% | Dow ~+0.5% (first winning week in three); Nasdaq ~+0.9% |
