Nifty IT index was the top gainer on October 15 by gaining 2%, taking the index's three-session rise to about 8%. Infosys, TCS and HCLTech added 3% each.
The information technology index notched its highest level in over a month at 30,856.90 points on October 15. Healthy earnings reported by Tata Consultancy Services and HCL Technologies earlier cheered investors, and the steep fall in shares of companies linked to the development of artificial intelligence infrastructure in Asia earlier in the day and on Wall Street overnight bolstered sentiment. In Nifty IT, Oracle Financial Services Software was the only one to trade lower.
"The strength in the IT stocks following the results of HCLTech and the optimism surrounding that will hold the IT index strong," said VK Vijayakumar, chief investment strategist at Geojit Investments.
Tech Mahindra and Wipro added 3.5% and 1.7%, respectively, ahead of their quarterly results due later in the day.
Other Asian markets fell, dragged by AI-linked stocks, as quicker-than-expected US inflation reinforced concerns over tighter global monetary conditions, eroding the appeal of high-growth companies whose valuations are sensitive to interest-rate assumptions.
