MUMBAI: Stock market barometer Sensex on Wednesday tumbled 310 points, as investors were spooked by an overnight crash in US stocks and weakness in Asian and European markets over concerns about the deepening financial crisis in Greece.

The 30-share Sensex fell for the second consecutive day to close at 17,380.08, down 310.54 points or 1.76 per cent -- the worst since February five. It touched a low of 17,344.58 during the day.
The National Stock Exchange’s 50-share Nifty index too fell 1.75 per cent to settle at 5,215.45 points.
Trading sentiment was also affected by bluechips such as RIL, ICICI Bank, Maruti and Bharti Airtel falling short of Dalal Street’s expectations, brokers said.
Index heavyweight Reliance Industries, which is slipping since the announcement of its quarterly results, nosedived further by 4.16 per cent to Rs 1,017. ICICI Bank fell 2.93 per cent to Rs 918.65.
Among the 30 constituents of Sensex, 25 scrips ended in the red, while five stocks managed to buck the trend and ended in the positive territory.
Among the losers in Sensex firms, Jaiprakash Associates was the worst sufferer which dropped 4.48 per cent. Tata Steel declined 3.52 per cent and was followed by DLF that dipped by 3.17 per cent and Tata Motors by 3 per cent.
All the 13 sectoral indices of the BSE ended in red with falling in the range of 1-4 per cent.
