Trading was suspended in the market for an hour. The markets had crashed on the wake of Securities and Exchange Board of India's (Sebi) proposal to tighten the rules for purchase of shares and bonds in Indian companies through the participatory note (PN) route.
The Sensex recovered sharply from the day's low (17,308 points) and touched an intra-day high of 18,841 points - up 1,533 points (8.9%) from the day's low.
The Sensex finally ended with a loss of 336 points (1.8%) at 18,716.
Here are the 10 biggest falls in the Indian stock market history:
May 18, 2006: The Sensex registered a fall of 826 points (6.76 per cent) to close at 11,391, it's biggest ever, following heavy selling by FIIs, retail investors and a weakness in global markets.
April 28, 1992: The Sensex registered a fall of 570 points (12.77 per cent) to close at 3,870, it's second-largest, following the coming to light of the Harshad Mehta securities scam.
