Market breadth remained fairly negative with 27 of the 30 Sensex components ending the day in red, while volatility index VIX jumped over 18 per cent intraday. The index is a measure of the market's expectation of volatility over the near term.

Stock of Tata Motors was the worst performer on both the headline indices and sank over 6 per cent on BSE.

China's Caixin/Markit Manufacturing Purchasing Managers' Index (PMI) slipped to 48.2 in December as compared to 48.6 in November. Any reading below 50-point level signals contraction.
