The ten most valued domestic firms together lost a massive Rs 3.35 lakh crore from their market capitalisation last week, as the equity markets witnessed a massive sell-off amid fears of coronavirus outbreak turning into a pandemic.

Reliance Industries was the biggest hit, as its market capitalisation (m-cap) declined by Rs 99,430.93 crore to Rs 8,42,262.64 crore.

On February 28, the Sensex logged its second-biggest one-day fall in history as concerns over the rapidly-spreading coronavirus triggered a manic global sell-off.

Following the downtrend in the broader market, the top ten firms witnessed significant erosion in their market capitalisation, traders said.

Among other blue-chip firms, the m-cap of Hindustan Unilever plunged Rs 15,792.31 crore to Rs 4,70,824.97 crore, and that of HDFC Bank declined by Rs 21,369.47 crore to Rs 6,45,544.93 crore.

The carnage in the equity markets wiped out investor wealth worth Rs 5,45,452.52 crore, with the total market capitalisation of BSE-listed companies standing at Rs 1,46,94,571.56 crore as on February 28.
