New Delhi [India], February 12 (ANI): Indian stock indices dipped Thursday, weighed down by a nosedive in IT counters, with analysts attributing it to mounting concerns over AI-led disruptions.

Sensex closed at 83,674.92 points, down 558.72 points or 0.66 per cent, while Nifty closed at 25,807.20 points, down 146.65 points or 0.57 per cent.

Among the sectoral indices, IT declined the most, by 5.51 per cent, according to the data.

'A nosedive correction in the IT index triggered by mounting concerns over AI-led disruptions, along with low expectations of a US Fed rate cut due to strong US job data and unemployment rates, dampened investor sentiment. Globally, AI is reshaping markets by compressing margins in service-intensive sectors and increasing concentration-led volatility. In India, this technology shift is likely to structurally transform IT services by accelerating delivery timelines and automating volume-driven tasks, thereby challenging the traditional headcount-based outsourcing model,' said Vinod Nair, Head of Research, Geojit Investments Limited.

Nair added that a weak sentiment in the IT sector, along with lingering geopolitical tensions between the US and Iran, may influence investors to take a cautious approach in the near term.

Heavyweights such as Infosys, TCS, Wipro, Tech Mahindra, and HCL Tech led the decline, exerting significant pressure on the benchmark indices.

'The selloff was triggered by intensifying concerns around AI-led disruption and the potential impact on traditional outsourcing revenue models. Rapid advancements in enterprise-grade AI tools capable of automating coding, analytics, legal drafting, and business workflows are prompting investors to reassess long-term growth assumptions for labor-intensive IT services. Additionally, stronger-than-expected US jobs data reduced expectations of near-term Federal Reserve rate cuts, raising concerns that discretionary IT spending from US clients may remain subdued,' said Ponmudi R, CEO of Enrich Money, a SEBI - registered online trading and wealth tech firm.

Earlier this week, Indian stock indices rose, taking cues from the interim trade deal with the US.

So far in 2026, Sensex dropped about 2 per cent on a cumulative basis. (ANI)
