TCS share price tumbles 9%: supports to watch in 2026

Steepest single-day slide since the 2020 crash

Shares of Tata Consultancy Services (TCS) came under heavy selling on Wednesday, falling more than 9% intraday and setting up what was described as its worst single-day decline since the COVID-19 market crash of 2020. The stock slipped to an intraday low of ₹2,224.80 on the NSE. It later closed at ₹2,244.40, down 8.28% for the day. The decline revived comparisons with March 2020, when the stock logged a much sharper one-day fall of about 12.7% on March 23, 2020.

Where the sell-off left the stock on the day

The day’s price action placed TCS among the major laggards, with one report noting TCS dropped 7.16% and led Sensex losers alongside Tech Mahindra and Infosys. The magnitude of the fall also pulled investor focus back to key chart levels that are often watched during high-volatility moves. Separately, sector-wide pressure was visible, with IT shares facing a broader sell-off that weighed on sentiment across large-cap names.

What technicians flagged: 100-day EMA resistance and reversal

Technical analysts linked the sharp reversal to resistance near the 100-day exponential moving average (EMA) zone. Sudeep Shah, Head of Technical Research and Derivatives Research at SBI Securities, said the stock faced strong resistance around ₹2,600 to ₹2,605, which triggered a reversal. He also pointed to TCS slipping below the Bollinger Band midline, a level that traders often track as a support marker during trending phases. With the fall, TCS moved below key short and long-term moving averages, which Shah described as a sign of a deteriorating trend.

Key support levels now in focus: ₹2,210 to ₹2,200

The immediate technical focus has shifted to the ₹2,210 to ₹2,200 zone, described by Shah as a crucial support band. According to the same view, a breakdown below this region could accelerate further downside. Separately, another analyst view cited a key level near the 52-week low around ₹2,206 as an important watch point. On the upside, ₹2,400 to ₹2,450 was identified as the first heavy supply zone, since a recent bounce attempt failed in that area.

Market cap risk narrative around ₹2,210

The sell-off also revived a market-cap threshold discussion. A separate report in Hindi noted that if TCS falls below ₹2,210, the company’s market capitalisation could slip below ₹8 lakh crore. While this framing depends on prevailing share count and market price at the time, it captures the immediate psychological importance of the ₹2,210 area during a steep drawdown.

What momentum indicators showed: RSI readings

Momentum indicators were cited as another reason traders are monitoring the stock closely. One update said TCS is nearing an “oversold” zone, with the daily Relative Strength Index (RSI) down to 39. That is above the commonly referenced oversold threshold of 30, but it still signals weakening momentum. Separately, during the February 2026 leg of the decline, another report described the RSI dipping to about 12.5, characterising it as an extreme oversold reading. Both references underline how quickly sentiment and positioning can shift when prices break multiple technical levels.

Performance snapshot: underperformance versus the benchmark

The drawdown has been part of a longer period of weakness, with multiple time-frame returns cited as negative.

One commentary also described TCS as “down nearly 23% in 2026” on margin pressure and weak growth visibility, reflecting a bearish fundamental narrative alongside the technical breakdown.

52-week range and recent lows: what the numbers show

Exchange-range data cited a 52-week low of ₹2,283 and a 52-week high of ₹3,630.50. It also stated TCS touched a fresh 52-week low of ₹2,283 on May 12, 2026. Alongside that, other references highlighted levels around ₹2,206 as a key low to watch, showing that different trackers and commentary pieces focused on slightly different reference points during fast-moving sessions.

The February 2026 slide: five-and-a-half-year low and market cap hit

Earlier in 2026, TCS fell to ₹2,585 on February 13, described as a five-and-a-half-year low and the lowest level since September 22, 2020, when it closed at ₹2,523. That decline was also linked to a drop in market capitalisation to about ₹9.60 lakh crore, a multi-year low that slipped below a previous trough of ₹9.77 lakh crore. The same set of reports pegged the fall as a 44% correction from the all-time high of ₹4,592 reached in August 2024. Another price reference for that date said TCS closed at ₹2,692.20, down 2.11%.

Sector context: AI disruption worries and the IT rout

The sell-off narrative repeatedly pointed to concerns around AI-led disruption and the impact on the traditional linear growth model of IT services. One report noted TCS had reported annualised AI services revenue of USD 1.8 billion in Q3 FY26, even as the stock corrected sharply from prior peaks. The broader technology tape remained weak too, with one update noting IT stocks dropped over 5% on a Thursday and the Nifty IT index moved close to a nearly 10-month low. The same commentary said the Nifty IT index declined 12.6% in 2025 and another 12.2% in 2026, highlighting sustained pressure on the segment.

Market impact and why these levels matter

Wednesday’s fall matters for investors mainly because several widely tracked technical levels were reported as breaking at once. The ₹2,210 to ₹2,200 band is being treated as a near-term pivot, while ₹2,400 to ₹2,450 has been positioned as an overhead supply zone where sellers could re-emerge. The repeated references to moving averages, the Bollinger Band midline, and RSI readings show how much of the near-term narrative is being driven by technical positioning rather than a single fresh fundamental trigger on the day. At the sector level, the IT weakness and the AI disruption discussion have coincided with sustained underperformance across time frames.

Conclusion

TCS’s more-than-9% intraday fall and 8.28% close-to-close drop has put fresh focus on ₹2,210 to ₹2,200 as a key support zone, with ₹2,400 to ₹2,450 cited as the first overhead supply area. Investors are also watching how the stock behaves around widely referenced lows and its stated 52-week range. With IT stocks under pressure and the AI disruption debate continuing, the next set of moves is likely to be judged against these clearly defined technical markers and any further company or sector updates.
