The Bombay Stock Exchange benchmark Sensex on Friday slumped over 332 points in opening trade on brisk selling by funds amid concerns over the euro-zone debt crisis.
The 30-share index, which had gained 111.19 points in the previous sessions, plunged by 332.65 points to 16,187.03 in the first five minutes of trading.
All the sectoral indices, led by realty and metal, were trading in the negative zone with losses up to 3.20 per cent.
Likewise, the wide—based National Stock Exchange index Nifty fell by 105.30 points to 4842.30 points.
Marketmen said investors sold shares heavily after a steep fall in the US and Asian stocks markets on concerns that the European fiscal crisis might deepen further.
Meanwhile, the US Dow Jones Industrial Average fell by 3.60 per cent lower in Thursday’s trade, while Japan Nikkei was down by 2.51 per cent in the morning trade on Friday.
