The Bombay Stock Exchange benchmark Sensex lost nearly 235 points in early trade on Tuesday on heavy selling by funds, triggered by weakening global trends.
The 30-share index, which gained nearly 112 points on Friday, tumbled 234.61 points at 15,573.03 in the first five minutes of trade.
Marketmen said the selling pressure was so strong that even better earnings by IT bellwether Infosys Technologies failed to support the falling market. Infosys Technologies' shares were up by Rs 38 at Rs 1,459.90.
Similarly, the wide-base National Stock Exchange's index, Nifty, lost 69.50 points to 4,708.30 as heavy-weight stocks like Larsen and Toubro, Tata Steel and Reliance Industries fell sharply.
