Domestic equities look to be good as of now. Increased optimism about economic recovery with continuous fall in daily caseload in second COVID wave and improvement in recovery rates has already led domestic equities to new highs, said Binod Modi, Head Strategy at Reliance Securities.

Further, the beginning of gradual withdrawal of restrictions by states, which hints at improvement in economic indicators from the current month, also lifted market mood, he added.

Elsewhere in Asia, bourses in Shanghai, Tokyo and Seoul were trading in the positive territory in mid-session deals, while Hong Kong was in the red.
