Tata Consultancy Services rose 3.9 percent, while Tech Mahindra gained 4.6 percent.
Axis Bank surged 5.8 percent while HDFC Bank gained 2.1 percent.
The Sensex rose 1.7 percent, while the broader Nifty gained 1.97 percent at 0847 GMT.
The October futures contract on the Nifty spiked as much as 2.87 percent earlier in the day in what multiple traders described as a "freak", or erroneous, trade.
