Explained: Why Accenture’s warning sparked a Rs 1.35 lakh crore meltdown for TCS, Infosys, other IT stocks

A brutal combination of demand deceleration, structural disruptions from artificial intelligence, and geopolitical headwinds has triggered a massive sell-off in Indian IT majors. A disappointing revenue guidance cut from global tech bellwether Accenture Plc sent shockwaves through Dalal Street, wiping out a staggering Rs 1.35 lakh crore in investor wealth in a single session.

The combined market capitalization of all Nifty IT stocks tumbled to Rs 21.57 lakh crore as the Nifty IT index crashed 6%. Infosys was the top loser, falling over 8%. Mphasis, TCS, Tech Mahindra, LTIMindtree, HCL Tech and Persistent were all down 5-6% each.

The single-day rout deepens the pain for the sector, pushing the Nifty IT index’s calendar year 2026 losses to 29%, amid mounting structural fears that generative AI is replacing the fundamental need for traditional IT services.

The Accenture shockwave: From Wall Street to Dalal Street

The immediate trigger for the carnage was overnight trading on Wall Street, where Accenture shares plunged 18% lower following its third-quarter earnings release for the May 2026 quarter.

While Accenture reported Q3 revenue of US$18.7 billion—up 3% year-on-year in constant currency (YoYcc), hitting the midpoint of its 1–5% guided range—the underlying metrics revealed severe pressure. Growth was heavily lopsided toward Managed Services (up 5% YoYcc), while high-value Consulting growth remained muted at just 1% YoYcc due to rapid cuts and delays in discretionary spending.

Crucially, Accenture lowered the top end of its full-year FY26 revenue growth guidance by 100 basis points to 3–4% (down from 3–5%). Adjusting for DOGE and inorganic contributions, the revised guidance implies a further moderation to -1.0% to +3.0% YoYcc growth for the fourth quarter, directly contradicting the consensus expectation of a growth acceleration for India’s top 6 IT firms.

More derating ahead for IT stocks?

Jefferies analyst Akshat Agarwal struck a cautious note, saying Accenture’s downward revision of its revenue growth guidance implies further growth moderation in the near term. He added that this may lead to further cuts to consensus earnings estimates for Indian IT and may also raise concerns on longer term growth outlook and PE multiples, and that focus on M&A and new client adds is likely to rise to support growth. Despite the 25% fall year-to-date, Jefferies reiterated its underweight stance, with Agarwal noting that growth uncertainty persists amidst AI pressures and a volatile macro.

Jefferies flagged three key takeaways for Indian IT names: first, the revised revenue growth guidance suggests further growth moderation which may lead to cuts in consensus expectations; second, soft growth on a low base is likely to raise concerns on the longer-term growth outlook and may drive further derating; and third, IT firms may have to look for new growth drivers such as mid-market deals and M&A to offset softness in traditional services growth. The brokerage noted that after Accenture’s 18% fall, the Top-5 Indian IT pack is trading at a 70% premium to Accenture, which poses further downside risks to the multiples of Indian IT firms.

Nomura said it believes the Middle East conflict is expected to have some effect on revenues and deal bookings in the first quarter of FY27, and that the indirect impacts can continue into the second quarter as it remains unclear how quickly spending behaviour will normalise, particularly in challenged sectors like automotive.

The brokerage also noted that, as it had flagged in a recent report, clients are moving beyond proof of concepts to live use cases in AI, and that AI will continue to drive demand for core fundamental elements like cloud, data and platform modernisation services.

Nomura expects the Middle East conflict’s impact to weigh on revenues in the near term for Indian IT services, while also expecting AI projects to scale up as clients move from proof-of-concept to live projects. However, it cautioned that a sharp growth revival hinges on macroeconomic improvement, particularly in the US. The brokerage said it prefers Infosys and Cognizant (both Buy-rated) among large-caps, Coforge among mid-caps, and eClerx among small-caps.

Motilal Oswal called the read-through for Indian IT “negative,” pointing out that outsourcing bookings are down 14.7% YoY, after decelerating sharply in the previous quarter as well. The brokerage noted that Accenture has called out the impact of the war, both direct impact from Middle East revenue and slower decision-making in EMEA, but said there are limited triggers right now to accelerate revenue. It added that the AI implementation revenue uptick remains too fragile, while discretionary spends continue to be hit from multiple directions: war, macro pressures, and AI.

The domestic brokerage firm expects first-quarter FY27 outcomes for most Indian IT large-caps to be similarly soft. On AI implementation, it believes the opportunity will surely materialise, but may not accrue to traditional vendors the way it did in the past, with a new, platformised AI-native vendor template set to emerge instead. It pointed to OpenAI’s DeployCo, and Anthropic’s services company, as the first credible blueprint of the next-generation system integrator, adding that this will not be a winner-takes-all market and that multiple vendors would survive as seen in past cycles, though not without a painful period of transition for the existing book of business.

Where are IT stocks headed?

Though the near-term consensus points to soft Q1FY27 earnings and potential estimate cuts, some market experts suggest the bottom may be nearing. Analysts note that buying could eventually emerge at lower levels as valuations become increasingly attractive after the steep correction.

While a sharp macroeconomic revival hinges heavily on spending normalization in the United States, investment preferences are becoming highly selective. Nomura stated it continues to prefer selective buying on dips, naming large-caps Infosys and Cognizant, mid-cap Coforge, and small-cap eClerx as its preferred names. Conversely, macro uncertainty will likely force traditional IT majors to aggressively chase M&A and mid-market client additions to replace missing legacy revenue streams.
