Infosys and other Indian IT heavyweights surged on Friday. The Nifty IT index climbed over 3% during the session.

Nvidia's strong quarterly earnings and optimistic revenue forecast triggered the rally. These results reassured global investors about the continued boom in artificial intelligence spending.
