Mumbai: The benchmark BSE Sensex extended losses on a fourth straight day as it fell by over 378 points on Thursday while NSE Nifty dipped below the 7,700 level in early deals as further sell-off in China forced the market to halt trading for the second time this week.
In addition, weakness in the rupee against the dollar too weighed on the sentiment. Asian markets were in deep red with Shanghai shares crashing 7.32%, forcing authorities to suspend trading, less than half an hour after opening.
The fall came amid worries over slowing growth in the world's second-largest economy, which have roiled investors worldwide, and with pressure on its currency from capital outflows.
China's central bank on Thursday lowered the yuan against dollar by 0.51% to 6.5646, the lowest since March 2011. The 30-share Sensex tumbled by 378.38 points or 1.48%, to 25,027.95 in early trade.
All the sectoral indices led by metal, capital goods and auto were trading in the negative zone with losses up to 2.18%. The gauge had lost 754.57 points in the previous three consecutive sessions.
The NSE Nifty cracked below the 7,700-mark by slumping 116.90 points or 1.51% to 7,624.10.
Major losers that dragged down the indices were Tata Motors, Tata Steel, Maruti Suzuki, Axis Bank, BHEL, ONGC, ICICI Bank, Adani Ports, M&M and Dr Reddy's.
Brokers said sentiment remained weak as investors indulged in offloading their positions, tracking a weak trend overseas on a slew of negative factors, including crude oil slumping to multi-year lows.
Besides, overnight losses in the US markets hurt sentiment, they added. In other Asian markets, Hong Kong's Hang Seng index was down 3.05% while Japan's Nikkei shed 1.78% in early trade. The US Dow Jones ended 1.47% lower in Wednesday's trade on more signs of a Chinese economic slowdown and a North Korean announcement that it completed a hydrogen bomb test.
