Mumbai: The BSE Sensex fell by over 158 points in opening trade on Thursday, extending  Wednesday’s losses on concerns over slowing industrial growth amid a weakening trend on other Asian bourses as worries over the euro zone debt crisis continued to dampen the investor sentiment.

The 30-share BSE benchmark index, which lost 121.37 points in Wednesday’s trade, moved down further by 158.51 points, or 1 per cent, to 15,722.63 in opening trade on Thursday.

In a similar fashion, the wide-based National Stock Exchange Nifty index declined by 48.15 points, or 1.01 per cent, to 4,715.10.

All the sectoral indices, led by metals and auto, were trading in the negative zone, with losses of up to 1.78 per cent.

Brokers said the market sentiment was badly dampened by concerns over slowing industrial growth and the rupee breaching the Rs 54 per US dollar-mark for the first time in history. The rupee depreciated by 46 paise to trade at a fresh record low of Rs 54.17 against the dollar in opening trade on Thursday.

In addition, a weakening trend on other Asian bourses in tandem with overnight losses in the US accelerated the selling activity.

In the Asia region, Hong Kong's Hang Seng index was down by 1.22 per cent and Japan's Nikkei index lost 1.32 per cent in morning trade on Thursday. The US Dow Jones Industrial Average ended 1.10 per cent lower in Wednesday’s trade.
