This article summarizes press coverage and company statements from October 13–16, 2026 for informational purposes. It is not investment advice. Stock prices change daily.
Key Takeaways
- Indian IT stocks rallied for about four sessions after September-quarter results. The Nifty IT index rose roughly 3.9% on Friday, October 16, to about 31,924.
- Tech Mahindra led the move with a gain of about 8% on the day. Infosys, TCS, HCLTech and Wipro also rose.
- IT stocks carried the broader market. The Sensex gained 413.66 points (0.56%) to close at 74,729.27, and the Nifty 50 rose 0.65% to 23,146.15.
- Reported drivers were TCS's September-quarter profit growth of about 15% year on year, a higher full-year growth outlook from HCLTech, and rising AI-linked revenue at large IT firms.
- Even after the bounce, the Sensex is still about 11% lower than a year ago, so this is a recovery inside a weak year.
What happened this week
IT stocks led the market from October 13, when TCS and HCLTech gained after their results, and the buying continued through Friday. On October 16 the Sensex briefly slipped into negative territory before IT stocks pulled it up. It closed at its highest level since September 23, according to Trading Economics.
The rally was narrow. The Nifty Midcap index fell about 0.12% and the Smallcap index ended flat the same day, so the gains came from a handful of large caps rather than the whole market.
Why IT stocks rose
Earnings. Tech Mahindra, Wipro, Infosys and TCS reported September-quarter results that analysts described as strong. TCS's profit was reported up about 15% year on year.
AI revenue. Coverage says Infosys and TCS reported meaningful AI-driven revenue. HCLTech's guidance upgrade added to the sense that demand is holding up.
Corporate action. Tech Mahindra's board was scheduled to meet on October 15–16 to consider a bonus issue, which drew extra attention to the stock.
Market backdrop. Reports also cite softer US bond yields, easing crude oil prices, a stronger rupee and SEBI's VWAP relief as supports for Friday's session.
What is still uncertain
IT companies earn most of their revenue from US and European clients, so a slowdown in tech spending there would show up in their numbers. Some analysts also question how much of the AI revenue is lasting rather than early project work. A four-day rally can also fade if profit-taking sets in.
What this means if you follow IT stocks
- Separate the news from the price move. Good results are already reflected in a stock that has risen 4 to 8% in a few sessions.
- Watch guidance, not only profit. HCLTech's higher outlook mattered because it points to future demand.
- Check the broader picture. A market that is down about 11% over a year can fall again even when one sector is strong.
- Expect volatility. Several IT stocks moved 3 to 8% on single days this week.
