Indian equity benchmarks Sensex and Nifty50 closed flat on Wednesday, February 4, 2026, ending a two-day rally. The BSE Sensex edged up by 78 points to settle at 83,818, while the Nifty 50 gained 48 points to finish at 25,776. Despite the marginal gains, the session was marked by significant volatility and a localized "SaaSpocalypse" in the technology sector. The Nifty IT index suffered its worst single-day crash since the 2020 pandemic, plunging 7% and wiping out nearly 2 trillion INR in market value. This sell-off was triggered by mounting concerns that rapid advancements in Artificial Intelligence (AI) tools are beginning to cannibalize traditional software maintenance and application revenue. Top IT heavyweights experienced sharp declines. TCS saw its consolidated net profit fall 14% year-on-year to 10,657 crore INR, despite a 5% rise in revenue to 67,087 crore INR. The firm declared a total dividend of 57 INR per share, including a 46 INR special dividend. Infosys also remained under pressure as investors weighed its 4 billion USD in new deal wins against the long-term threat of AI-driven disruption. In the automotive sector, Mahindra & Mahindra announced a historic milestone. The company secured its largest-ever export order to supply 35,000 Scorpio Pik Up units to Indonesia throughout 2026. This single contract is expected to match M&M’s entire annual export volume for the previous fiscal year, signaling a major boost for its international operations. Consumer goods major Marico made a strategic move into the wellness space by acquiring a 60% stake in Bengaluru-based Cosmix Wellness. The deal, valued at 226 crore INR, prices the plant-based nutrition brand at an equity valuation of 375 crore INR. This follows Marico's recent 226.8 crore INR acquisition of the snacking brand 4700 BC. Broad economic indicators remain resilient. The Economic Survey 2025–26 projects India’s real GDP growth at 7.4% for the current fiscal year. Foreign exchange reserves have climbed to a robust 701.4 billion USD as of mid-January, providing a significant buffer against global trade volatility. The market sentiment is currently influenced by the Union Budget 2026, which introduced a hike in Securities Transaction Tax (STT). Rates for futures were raised to 0.05%, while options premium tax increased to 0.15%. These changes have led to a cautious environment for derivative traders and high-frequency participants. Investors are now shifting focus toward the India–AI Impact Summit scheduled for mid-February in New Delhi. The event is expected to clarify how the domestic tech industry will integrate indigenous AI solutions to counter the ongoing pressure on traditional service models.
