There are two divergent trends in the governments' and market's response to the Omicron variant, said VK Vijayakumar, Chief investment Strategist at Geojit Financial Services.

"Governments, globally, are responding with caution and imposing some restrictions. In India too Maharashtra and Delhi have imposed some restrictions in the context of rising cases. But the markets have responded to the Omicron variant assuming that this marks the last phase of the pandemic," he said.

He further said, "a strong positive for the market is that FIIs have turned buyers. This augurs well for financials, particularly leading banking stocks whose valuations are attractive now. Rising crude is a macro headwind."

Elsewhere in Asia, bourses in Shanghai, Hong Kong, Seoul and Tokyo were trading with losses in mid-session deals.

Stock exchanges in the US largely ended with losses in the overnight session.

Meanwhile, international oil benchmark Brent crude rose 0.06 per cent to USD 78.72 per barrel.
