Mumbai, 12 March 2020: Indian equity markets went on a free-fall on Thursday as investors pressed and held the 'sell' button after the World Health Organisation (WHO) declared the novel coronavirus outbreak a "pandemic" and the United States suspended travel from Europe. The carnage on the Dalal Street on Thursday eroded investor wealth worth Rs 11 lakh crore. Overall, the Indian benchmark indices S&P Sensex and Nifty both slipped over 9 per cent each in intra-day and posted their biggest one-day fall in absolute terms.
