"After opening at a record high, the domestic markets slipped into the negative zone tracking cues from global peers due to spike in Covid cases across Asia," said Vinod Nair, Head of Research at Geojit Financial Services.
PSU banks were in focus in anticipation of progress in privatisation, he said, adding that the market got volatile in the closing hour during the FM's announcement on fresh stimulus, though it was focused on Covid-19 relief package mainly for healthcare and stressed sectors, which will benefit the broader economy.
Elsewhere in Asia, bourses in Shanghai, Hong Kong, Seoul and Tokyo ended with losses. Stock exchanges in Europe were trading in the red in mid-session deals.
Meanwhile, international oil benchmark Brent crude was trading 0.16 per cent lower at $75.26 per barrel.
