The Bombay Stock Exchange benchmark Sensex on Tuesday plunged by over 309 points in opening trade on heavy selling by funds, tracking a weak global trend.
The 30-share index, which had lost over 195 points on Monday, fell further by 309.27 points at 14,016.95.
Similarly, the National Stock Exchange's Nifty tumbled by 92 points at 4,143.25 in opening trade as heavy-weight stocks like Reliance Industries and Infosys recorded heavy losses.
Marketmen said a steep fall in the global stock markets, led by Hong Kong, mainly influenced the trading sentiments here.
Hong Kong's Hang Seng opened 3.28 per cent lower on Tuesday, while Japan's Nikkei was down 2.81 per cent in morning trade.
