Mumbai:  The BSE benchmark index Sensex on Wednesday fell by over 150 points in early trade, due to fresh selling by funds amid a weak trend on other Asian bourses.

The 30-share barometer, which had gained 21.70 points on Tuesday, lost 150.63 points, or 0.87 per cent, to 17,093.21 in the early trade.

The wide-based National Stock Exchange index Nifty dipped below 5,200 points to trade lower by 49.20 points, or 0.93 per cent, at 5,194.40.

All sectoral indices, led by metal and capital goods, were trading in the negative zone, with losses up to 1.62 per cent, which led to the fall in the Sensex.

Brokers said fresh selling by funds amid a weak trend on other Asian markets, following overnight heavy losses in the European and US markets due to fresh euro-zone debt worries and concerns over the global recovery, mainly dampened the trading sentiment here.

In the Asian region, the Hong Kong's Hang Seng index fell by 1.27 per cent, while Japan's Nikkei was down by 1.17 per cent in the early trade on Wednesday. The US Dow Jones Industrial Average ended 1.65 per cent lower in Tuesday's trade.
