Equity benchmark BSE Sensex plunged 811 points in fag-end sell-off on Tuesday after a see-saw session over fears of a recession brought about by the coronavirus pandemic.

After opening on a positive note, the 30-share index gyrated 1,653 points during the day. It finally settled 810.98 points, or 2.58 per cent, lower at 30,579.09.

The broader NSE Nifty slumped 230.35 points, or 2.50 per cent, to close at 8,967.05.

Top losers in the Sensex pack included ICICI Bank, IndusInd Bank, Bajaj Finance, Kotak Bank, HDFC, Infosys and SBI.

On the other hand, HUL, Hero MotoCorp, PowerGrid, Maruti and Asian Paints were among the gainers.

According to traders, value-buying lifted benchmarks during the first half of the session, but the gains could not be sustained as markets succumbed to coronavirus-led fears of a recession.

Markets in Europe cracked up to 3 per cent in early trade.

The rupee appreciated marginally to 74.20 per US dollar (intraday).
