Benchmark indices closed 2 percent higher each with Sensex ending the session with a gain of 622 points at 30,818.61 and Nifty settling 187 points higher at 9,066.55.
"Benchmark indices closed up by more than 2 percent, in spite of mixed global cues and unabated increase in the number of infections across India. The government cabinet approvals of some of the proposed measures and leaving the door open for further stimulus measures could have played a part in the positivity. Investors are advised to remain cautious," said Vinod Nair, Head of Research at Geojit Financial Services.
