The Bombay Stock Exchange 30-share Sensex resumed lower at 19,034.00. After trading in a narrow 100-point band, heavy selling in RIL, L&T, ICICI Bank, Bharti and the auto pack dragged the Sensex into negative zone.
It finally ended at 18,801.64, a loss of 239.31 points or 1.26 per cent, snapping the Sensex's four-day long winning run where it gained 359.53 points. This is Sensex's lowest close since 18,704.53 on March 26.
Brokers said the market has been lacking positive triggers while reports of lower quarterly earnings by companies in the fourth quarter sparked selling.
Sanjeev Zarbade, Vice President, Private Client Group Research, Kotak Securities said: "Sensex came under severe selling pressure especially in the last hour of the session. Likely reasons for the market fall could be speculation about early general elections and weak macroeconomic datapoints."
Automakers lead falls on concern over slowing vehicle sales and the sectoral index dropped 2.23 per cent led by stocks of Tata Motors, Bajaj Auto and Maruti Suzuki. Bharti Airtel, the biggest mobile-phone services provider, fell by 3.95 percent.
Besides the country's private sector output for the month of March witnessing the slowest pace of expansion in 17 months, the sentiment further dampened on weak trend in Asia and lower opening in Europe, traders said.
