The Sensex bounced 1,130 points from Monday’s intraday low to close up 77.05 points at 75,315.04 on May 18, 2026, per BSE data, yet that near-flat close masks one of the most decisive sector rotations Dalal Street has seen in weeks. The Nifty IT index had crashed 7.3% in a single week just days before, making Monday’s sharp recovery the direct counterMove. IT led every gainer. PSU banks, power, and metals led every loser. The benchmark flatlined. What happened inside it absolutely did not.
The Numbers the Flat Close Is Hiding
On the Sensex, buying interest was led by TECHM at +4.39%, followed by INFY at +2.15%, BHARTIARTL at +1.76%, BAJAJFINSV at +1.52%, and SUNPHARMA at +1.34%. On the sell side, TATASTEEL fell 3.21%, POWERGRID dropped 3.07%, SBIN slid 2.38%, and NTPC declined 1.86%. Both things, sharp IT gains and sharp PSU losses, happened simultaneously, inside an index that printed +77 points. That is the real story Monday’s headline missed.
The Nifty IT index extended Friday’s rally, rising over 2% and emerging as the only sector trading with gains, broad-based across all 10 index constituents. Meanwhile, the Nifty IT rebound was supported by value buying, gains in IT stocks, and easing volatility, but the India VIX still rose 4.47% to 19.63, confirming the calm on the surface was not calm underneath.

Why IT Is Bouncing — And What’s Actually Driving It
The Nifty IT index had declined 3.73% to close at 28,235 on May 12, its lowest level since May 2023, after OpenAI announced the acquisition of consulting firm Tomoro as part of its push to deepen enterprise AI adoption. By Thursday May 14, the week’s cumulative fall had reached 7.3%, with TCS, Infosys, HCL Tech, LTIMindtree, Tata Elxsi, Zensar, and Birla Soft all hitting multi-year lows.
Monday’s rebound had one primary mechanical driver. The rupee crashed to a record intraday low of 96.39 against the dollar on May 18, part of a 5.5% decline since the Iran-linked conflict began in late February. For IT exporters billing in dollars and reporting in rupees, every rupee of currency weakness is a direct earnings tailwind that requires zero operational improvement to materialise.
Institutional money rotated sharply into defensive, dollar-earning businesses insulated from the macro turbulence gripping rate-sensitive and oil-exposed sectors.
G Chokkalingam, founder and head of research at Equinomics Research, said a 10–12% upside from recent bottoms is quite possible. “IT stocks have been beaten down very badly, causing their valuation multiples to shrink significantly. Additionally, the Indian rupee is depreciating and hitting new record lows, which acts as a positive tailwind for these export-driven companies,” he told Business Standard.
No, investors should not read Monday as a sector recovery. This is a tactically oversold bounce driven by currency, not fundamentals. BofA has an “Underweight” rating on India’s IT sector.
Amish Shah, head of India research at BofA Global Research, told Reuters in April 2026 that some large private lenders are trading 1.5 to 2.5 standard deviations below historical average valuations, calling banks, not IT, the structural value play. The rupee can reverse. The AI disruption thesis that drove the 7.3% weekly crash is not going away.
IT vs PSU—Sector Snapshot
| Sector | Monday Move | Weekly Fall (May 12–16) | YTD |
|---|---|---|---|
| Nifty IT | +2%+ (only green sector) | -7.3% | -27% |
| Nifty PSU Bank | -2.43% | Negative | -4.18% (2 sessions) |
| Nifty 50 | +0.03% | -3% | -9.5% |
| BSE Breadth | 1,264 rose | 3,034 fell | Negative |
The Less Obvious Detail Nobody Is Reporting
Oracle Financial Services Software has emerged as the sole outperformer in the Nifty IT pack in calendar year 2026, gaining 16% year-to-date even as the sectoral index has fallen nearly 28%, according to ACE Equities data. Nine of the 10 Nifty IT constituents have posted negative returns: LTIM is down 35%, Infosys is down 32%, and HCL Tech and TCS are both down 30%.
What makes OFSS different: “OFSS’s rally appears relatively sustainable, as growth is driven by a product-led banking software model rather than discretionary IT services spending. The company delivered strong Q4 FY26 results with around 20% revenue growth and sharp margin expansion to 51%,” said Anshul Jethi, research analyst at LKP Securities.
For Q4 FY26, OFSS reported revenue of ₹2,065 crore up 20% year-on-year, operating income of ₹1,049 crore up 39%, and net income of ₹842 crore up 31%. Its FLEXCUBE and OBDX banking platforms generate annuity-like revenues with high switching costs, the exact opposite of the project-based, discretionary IT spend that OpenAI’s deployment push is threatening. While 9 stocks in the IT index bleed, OFSS quietly proves the model matters more than the macro.
Why PSU Stocks Are Bleeding While IT Recovers
The two moves are mechanically connected. Brent crude hit an intraday high of $111.29 a barrel on Monday as Trump warned Iran of harder strikes, per an Axios report, with boiling crude, rising US bond yields, and a record-low rupee cited as the five key reasons markets opened sharply lower. The Nifty PSU Bank index tumbled 2.43% and has declined 4.18% across two consecutive sessions. PFC fell 3.60% and RECLTD dropped 3.54% alongside SBI’s 2.53% drop.
Higher crude squeezes the government’s fiscal math, raises inflation anxiety, delays capex allocations, and hits infrastructure-linked PSUs the hardest. Private financials moved differently: KOTAKBANK gained 1.14%, ICICIBANK rose 0.58%, and FEDERALBNK added 0.80%, showing the market is not rejecting banking broadly. It is specifically rejecting state-linked credit risk while the crude-fiscal chain is live.

FAQ
Q. IT stocks today—is the sector rotation from PSU to IT real?
The rotation is real but narrow. On the BSE, 1,264 shares rose and 3,034 fell on Monday, so while IT gained and the index printed positive, three in four stocks still declined. This is a defensive accumulation in dollar earners, not a broad market turn toward IT.
Q. Infosys and TCS share prices: Why did they rise after falling all week?
Currency, not fundamentals. The rupee hit a record low of 96.39 intraday against the dollar, amplifying the dollar-revenue advantage for IT exporters. In the last two sessions combined, the Nifty IT index has surged nearly 4%, but it remains 27% lower on a YTD basis. The bounce is from a very deep hole.
Q. Sector rotation in Indian markets: Which sector wins from here?
Private banks, per BofA. Amish Shah of BofA told Reuters in April 2026 that some large private lenders are at their cheapest levels in years, 1.5 to 2.5 standard deviations below historical average valuations, and BofA has an “Overweight” on large private banks versus “Underweight” on IT. The AI disruption risk caps IT’s medium-term ceiling regardless of the rupee tailwind.
The Nifty IT index has now recovered nearly 4% across two sessions following its worst week since the COVID-19 sell-off; the next decisive test is whether institutional buying sustains when the rupee stabilises and the AI disruption narrative reasserts itself.
