V K Vijayakumar, Chief Investment Strategist at Geojit Financial Services said, spiking COVID tells us that the light at the end of the tunnel, which the market is focussed on, is a long way away. But the market is taking cues from the second wave experience of other countries where the curve flattened and fell in around two months.

"This explains the resilience of the market in the midst of very negative COVID-related news. An important point to be understood is that global markets are highly correlated, and therefore, a major correction is likely to be global," he stated.

Elsewhere in Asia, bourses in Shanghai, Hong Kong, Seoul and Tokyo were trading on a negative note in mid-session deals.

Bourses on Wall Street ended with gains in overnight sessions.

Meanwhile, international oil benchmark Brent crude was trading 0.44 per cent higher at USD 67.75 per barrel.
