Rs 82,500 crore rally in 3 days: Why TCS, HCL Tech, other IT stocks jumped up to 12% in 3 days and will the boom last?

Indian IT stocks surged 8% across the three sessions, adding Rs 82,500 crore to the sector’s market value. This rally showed renewed investor buying despite recent worries that artificial intelligence could disrupt technology-services demand.

HCLTech led the advance, climbing 12%, while TCS gained 11% and Tech Mahindra rose 10.60%. Infosys added 9%, while Wipro increased 7%, showing gains spread across major companies.

The immediate backdrop was stronger-than-expected earnings, including TCS’s 15% year-on-year profit growth to Rs 13,884 crore. Accenture also reassured investors that AI would create more new demand than the demand it replaces. Still, rapid AI adoption could pressure future earnings and valuations. Analysts expect near-term support after HCLTech’s results but warn that profit-taking and volatility may follow the sharp rally.

The rally refers to a rapid rise across India’s listed technology companies, measured by the Nifty IT index. Over three sessions, the index gained 8%, showing a strong shift in investor sentiment toward the sector.

The move added Rs 82,500 crore to the sector’s total market value, meaning investors valued these companies collectively much higher. HCLTech led with a 12% rise, followed by TCS at 11% and Tech Mahindra at 10.60%.

Infosys climbed 9%, while Wipro advanced 7%, confirming that gains extended across major IT stocks. The gains came despite a global selloff in artificial intelligence shares after hotter-than-expected US inflation data. Accenture said AI could create more new demand than it replaces, supporting longer-term technology spending. However, analysts warned that profit-taking and volatility could follow after such a sharp rally.

The Nifty IT index is a market barometer for India’s leading listed technology companies. It reflects their combined share-price performance, so investors use it to judge sector momentum. When it rises, the sector’s overall market value generally increases, although individual companies can move differently.

Over the past three sessions, it rose 8% and added Rs 82,500 crore to market capitalisation. HCLTech led with 12% gains, followed by TCS at 11% and Tech Mahindra at 10.60%. Infosys gained 9%, while Wipro rose 7%. These moves explain the index’s rise: stronger share prices lift the combined measure.

This rally followed better-than-expected IT earnings and improved sentiment after HCLTech’s results. TCS reported 15% year-on-year profit growth in its second quarter, to Rs 13,884 crore. However, the index is not a guarantee of future gains. Analysts cited AI adoption concerns and warned that profit-taking and volatility could follow the sharp rally.

Better-than-expected earnings showed that Indian IT companies were still winning business and protecting profits, despite worries that artificial intelligence could replace some services. Accenture’s upbeat outlook added global evidence: technology demand created by AI may exceed the work it displaces. Together, these signals reduced fears about weakening demand and supported confidence in future growth.

TCS provided a concrete example. Its second-quarter net profit rose 15% year on year to Rs 13,884 crore, while revenue increased 0.5% sequentially in constant-currency terms. Its 24% operating margin and broad-based growth across international markets suggested clients were continuing to spend, giving investors a reason to revalue the wider sector.

The response was visible in prices: the Nifty IT index gained 8% in three sessions, adding Rs 82,500 crore in market value. Accenture expects mid-single-digit revenue growth in 2027 and 2028, and mid-to-high single-digit growth in 2029. Still, investors remain cautious because AI investment costs, stretched valuations, and uncertain rollout could bring volatility or profit-taking.

Higher-than-expected US inflation can push technology-stock prices lower worldwide. Investors may expect the Federal Reserve to keep interest rates higher, making future company profits less valuable today and raising borrowing costs.

That reaction appeared in the article: after September US consumer inflation beat expectations, Asian markets opened lower and US AI stocks fell overnight. South Korea’s KOSPI dropped 5.6%, Japan’s Nikkei 1.3%, and S&P 500 futures 0.3%. Higher rates can also make expensive AI projects harder to justify, especially when profits remain years away.

The pressure is not universal or permanent. Indian IT shares gained 8% in three sessions, adding Rs 82,500 crore in market value, while HCLTech rose 12%. Strong earnings and improving demand can offset rate worries, but stretched valuations and heavy AI spending may increase volatility. Investors will watch whether inflation cools, borrowing costs stabilize, and AI investments produce returns.

AI can reduce demand for traditional IT work by automating repetitive tasks, but it can also create entirely new projects. Companies may need fewer hours for routine coding or support. Yet they may need advice, software, data systems, and training to use AI safely and profitably.

Accenture illustrates the shift. CEO Julie Sweet said AI efficiencies could affect its business, but new demand should exceed replaced demand. Accenture expects mid-single-digit revenue growth in 2027 and 2028, supported partly by acquisitions.

The outcome remains uncertain. TCS reported 15% year-on-year profit growth in the second quarter, while the Nifty IT index gained 8% over three sessions. However, Broadcom and Intel leaders warned that expensive AI investment may face capital constraints, so adoption could slow.

A stock’s price reflects what investors expect the business will earn later, not only what it earns today. They value those expected profits because future cash can justify today’s price, while uncertainty makes investors pay less. A high valuation means investors already assume strong growth, so even a small disappointment can trigger heavy selling.

When investors expect AI to create more technology demand than it replaces, expected profits rise. TCS reported 15% year-on-year profit growth to Rs 13,884 crore, while HCLTech helped lead the Nifty IT index to an 8% three-session gain. Accenture’s CEO said AI-driven new demand should exceed replaced demand, supporting that optimistic view.

Yet Broadcom’s Hock Tan and Intel’s Lip-Bu Tan warned that rising capital costs could constrain AI expansion. If expensive investment produces uncertain profits, investors lower growth forecasts and valuations. Asian markets weakened after hotter-than-expected US inflation, and South Korea’s KOSPI fell 5.6%, showing how quickly expectations can reverse. After sharp rallies, profit-taking becomes more likely, especially when valuations already assume strong growth.
