On April 10, 2026, two things happened simultaneously in Indian markets that seemed to contradict each other.
Nifty 50 closed at 24,050.60, up 275 points, or 1.16%, for the session. Auto stocks gained 2.8%. Banking stocks rose nearly 2%. The broader market was firmly in risk-on mode following the US-Iran ceasefire that had eased global tensions since earlier in the week.
At the same time, the Nifty IT index fell roughly 2%. TCS, India's largest IT company by market cap, dropped 3% despite reporting a 12% year-on-year increase in net profit. Infosys, the second-largest, fell around 4% despite showing Q4 PAT growth.
Most retail investors who read the profit headlines were confused. Most institutional traders were not.
What Actually Happened
The confusion comes from a fundamental misunderstanding of how equity markets price earnings.
Stock prices don't respond to what a company earns in absolute terms. They respond to the gap between what analysts expected and what the company actually delivered — and more critically, to what management says is coming next.
Before every results season, hundreds of equity research analysts at brokerages and funds publish their earnings models. Revenue forecast, EBITDA margin estimate, net profit target, EPS projection — all of it modelled in detail. These forecasts get averaged into what's known as the consensus estimate. By the time the company announces results, this consensus is already embedded in the stock price.
A company can report record profits and have its stock fall. If the consensus had priced in even higher profits, the actual result is a disappointment.
This is the mechanism behind today's TCS sell-off. Revenue came in at ₹70,698 crore — up 10% year-on-year. Net profit rose 12%. By any historical measure, these are strong numbers. But the market's issue wasn't with Q4. It was with the question of where TCS goes from here.
The TCS Problem: AI Is Eating the Revenue Model
TCS and the broader Indian IT sector have faced a structural headwind throughout FY26. Traditional IT services — application development, maintenance, testing, infrastructure management — are being automated by AI tools. Clients are getting more output from fewer service hours. Billing rates are under pressure. Deal sizes for traditional work are shrinking.
TCS management's commentary reflected this reality. The BFSI (banking, financial services, and insurance) segment, historically the largest revenue driver for Indian IT majors, showed tepid demand. Management signalled that the recovery in discretionary IT spending, which had been expected in FY27, may be further delayed.
Analysts tracking TCS noted that despite the profit growth, the earnings upgrade cycle — where analysts progressively raise future estimates — is not happening. Some brokerages flagged potential for only modest earnings growth through FY29. For a large-cap stock where the forward multiple matters as much as current profits, that trajectory is not reassuring.
Infosys and the Guidance Problem
Infosys compounded this for the sector.
Its Q4 FY26 results showed a sequential revenue decline of 3.5% in constant currency terms — a 4.2% decline in dollar terms — which missed both company and analyst expectations. More importantly, management issued FY27 guidance of just 0% to 3% revenue growth, with margins expected in the 20–22% range.
That guidance line was the trigger for the sell-off.
When a company like Infosys, which had historically guided conservatively and then beaten its own guidance, comes out with a range starting at zero, it signals that demand visibility is genuinely poor. The FY27 guidance essentially told the market that there is no confident recovery story to invest in yet.
Infosys ADRs (American Depository Receipts traded on US exchanges) fell approximately 4% after the results.
What This Looks Like to a Retail Investor vs an Institutional One
A retail investor reading the headline — "Infosys profit grows, TCS revenue up 10%" — might conclude these are good results. They might even buy the dip, reasoning that falling stocks on good results represent an opportunity.
An institutional investor reads the same results and focuses on three different data points:
- The surprise gap: Did the company beat or miss the consensus estimate? By how much?
- The guidance trajectory: Is management raising or lowering its forward outlook? Is the bar going up or down?
- The narrative shift: Is the management commentary becoming more or less confident about demand recovery?
On all three of these metrics, both TCS and Infosys disappointed. The profit growth was real but it came against a backdrop of slowing forward momentum. That's a very different investment signal from profit growth driven by accelerating demand.
The Broader Sector Context
Indian IT stocks had already underperformed the broader market for much of FY26. The Nifty IT index was down roughly 20% from its peaks entering results season, having been weighed down by concerns about:
- AI-driven productivity gains reducing demand for traditional services
- Geopolitical uncertainty affecting client spending in the US and Europe
- Dollar revenue stagnation amid rupee fluctuation
Today's results did not resolve any of these concerns. They confirmed them.
The sector's Q4 results essentially told the market: the AI disruption story is real, the recovery is not imminent, and the best the large Indian IT companies can do in the near term is defend margins.
What Nifty Did Instead
While IT dragged, the rest of the market interpreted today's environment very differently.
The US-Iran ceasefire had removed a major tail risk — oil supply disruption — that had weighed on the market since early April. With that fear fading, investors rotated into sectors that benefit from a stable, low-volatility environment: automobiles, banking, and real estate.
Bajaj Auto, Eicher Motors, Mahindra & Mahindra, and Asian Paints were among the top Nifty 50 gainers. ICICI Bank contributed meaningfully to the advance. India VIX, the volatility index, fell approximately 7%, signalling that the broader market fear was receding even as IT-specific concerns remained.
This is what sector divergence looks like in practice. Macro risk-off → macro risk-on transition. Capital moves from defensive or pressured sectors into growth and cyclical ones. The overall index moves up even while a major component moves down.
The Lesson for Indian Investors
If you hold Indian IT stocks — TCS, Infosys, Wipro, HCL Tech, Tech Mahindra — and you're using quarterly results as your primary signal for position management, today is a reminder that the profit headline is the last thing you should anchor to.
Before earnings day, look up the consensus estimate. This is available on financial platforms like Trendlyne, Screener, and Bloomberg Terminal. Know what the market expects before the number arrives.
On results day, watch for three things before you decide to hold, buy, or sell:
Revenue and profit vs consensus — Not vs last quarter or last year. Vs what analysts expected this quarter.
Margin guidance — Is the company guiding margins to expand, hold, or compress? Margin compression usually triggers selling regardless of headline profit.
Management commentary tone — Listen to the earnings call or read the transcript. Cautious, hedging language about demand visibility is a forward signal the headline number doesn't capture.
Today's TCS and Infosys results were not bad by historical standards. But they were disappointing by the forward-looking standards the market was applying. Understanding that distinction is the difference between being confused by a 3% post-results drop and understanding exactly why it happened.
