Indian IT stocks tumbled on Friday after Accenture warned its growth is slowing, putting the sector on track for its worst year since 2008.
Accenture is the firm markets watch most closely for IT services demand, so its outlook tends to ripple straight through to every major outsourcing player.
TCS and Infosys sell into the same Fortune 500 client base as Accenture, which is why its guidance carries so much weight in Mumbai.
Tata Consultancy Services lost as much as 6.5% in Mumbai trading, hitting its lowest level since 2020, while Infosys dropped 8.7% after its US-listed shares fell 10% overnight.
The pain spread across Asia, with Japan's NEC and BayCurrent both finishing lower as investors marked down the entire IT services group.
The trigger was Accenture itself, which shed 20% Thursday after telling investors growth would slow in coming quarters, blaming slower client decisions tied to the Middle East conflict and disruption from AI.
The Dublin-based consulting giant has long been viewed as a leading indicator for Indian IT, since its clients and business model overlap closely with TCS and Infosys.

For years, Indian IT firms bet that AI would expand corporate tech budgets, bringing more contracts and more work for the outsourcing firms that powered the country's software boom.
Accenture's update suggests the opposite is happening, with client budgets staying flat as money gets moved toward AI instead of growing the overall spend.
That's a direct hit to the Indian IT model, which mirrors Accenture's almost exactly.
Emkay Global analyst Dipeshkumar Mehta said Accenture's commentary indicated AI is not expanding client budgets as spending is getting reallocated, calling it a challenge to the "AI lifts the wallet" thesis the whole sector has been built on.
The shift also pressures the labor-heavy model Indian outsourcers have run for decades, where revenue grows with headcount rather than with software efficiency.
All of this is showing up on the tape, with the NSE Nifty IT Index now down more than 32% from its December peak and over $100 billion in market value erased along the way.
Accenture also said it's targeting mid-market clients - smaller companies that have long been bread and butter for Indian firms.
Systematix analyst Ashis Dash said the move "raises competition and pricing pressure" for Indian IT, piling another headwind on top of the AI shift.
Indian IT earnings season kicks off in January, giving investors their first direct read on whether the Accenture warning is a one-off or an industry trend.
The bigger question is whether this is a rough patch or the start of something longer, and Friday's selloff suggests investors are betting on the latter.
