The Indian IT sector witnessed one of its sharpest sell-offs of 2026, with the Nifty IT index plunging 6% in a single trading session, wiping out around ₹1.7 lakh crore in investor wealth. According to latest reports, all ten index constituents ended the session in the red, with TCS, LTIMindtree and Persistent Systems leading the decline, falling as much as 9%. The sector has now fallen nearly 23% since the start of 2026, erasing approximately ₹6.6 lakh crore in market value. This represents the most significant decline since the COVID-led market crash of 2020, when the Nifty IT index had fallen 38.4% over a 231-day period.
Tata Consultancy Services (TCS) shares tumbled 2% Monday, extending a four-day loss to 12%, as rising U.S. bond yields fueled fears of further Federal Reserve rate hikes. The stock hit an intraday low of ₹2,144 on BSE, marking the most significant decline since the historic plunge on March 12, 2020. As per The Economic Times, TCS is now trading at ₹2,238.90, just 1.4% above its 52-week low of ₹2,206.40. The stock had climbed 8% across the two sessions to Tuesday's close of ₹2,446.90, but Wednesday's sell-off wiped out the entire gain from the recent rally. TCS now trades at a P/E ratio of 16.46x, significantly below its historical averages.
The sharp correction in IT stocks comes as investors grapple with fears around artificial intelligence disruption, weak global demand and rising geopolitical uncertainty. According to Jefferies analysis, Generative AI could structurally reduce revenue from traditional Application Managed Services (AMS) by as much as 25% over time. The potential revenue exposure is estimated at ₹66,755 crore, equivalent to roughly one-fourth of TCS's annual sales and larger than many Nifty 500 companies' annual revenue. While this represents a long-term scenario rather than an immediate earnings hit, it highlights the scale of disruption that AI could bring to the IT services industry. Apart from AI concerns, Indian IT companies are also dealing with weaker demand from overseas markets, with the United States and Europe facing economic uncertainty.
The IT sector decline was part of a broader market crash that affected smallcap and midcap stocks significantly. According to latest market data, the Nifty Midcap 100 index crashed 1.6% (nearly 950 points) while the Nifty Smallcap 100 index lost 1.4% (around 254 points) as of 12:20 pm on Wednesday. The broader market indices are currently underperforming the benchmark Nifty 50, which dropped around 1.3%. Several smallcap and midcap companies saw significant declines, with Tata Technologies, Creditacess Grameen, NBCC and Zensar Technologies shares falling around 4% each, while CAMS, Triveni Turbine, PNB Housing Finance, Firstsource Solutions, Aarti Industries and Sagility shares dropping over 3% each. The crash was attributed to persistent FII selling, a weakening rupee, and global factors, with analysts pointing to energy shocks and current account deficit concerns impacting market sentiment.
Technical analysts warn of potential further downside based on key technical indicators. According to The Economic Times, technical expert Shah noted that momentum indicators have weakened, with the RSI turning lower after approaching the 60 mark, signalling a loss of bullish momentum. The stock has slipped below the Bollinger Band midline, a level often considered an important support. Shah added that the ₹2,210-2,200 zone remains a crucial support, and a breakdown below this level could accelerate further downside. Harshal Dasani from INVasset PMS emphasized that the ₹2,206 level is the key level to watch, as a decisive close below that zone would weaken the structure further. Dasani noted that the stock has fallen below several key short- and long-term moving averages, indicating a weakening trend, and suggested that the ₹2,400-2,450 range represents a significant supply zone that any rally must overcome.
