The key index, however, registered a very negligible change of 0.09 points at 19,663.64 points. It had closed at 19,663.55 yesterday.
After a better start at 19,839.80, the Sensex failed to hold initial gains as disappointing industrial and export data hit hard. The gauge touched the day's low of 19,619.83.
The National Stock Exchange index Nifty fell by 17.35 points to 5,951.30, after climbing to 6,018.85 at the outset.
IT stocks led by Infosys saved the market from any eventuality as 26 stocks of the 30-BSE index components were down following reports of the industrial output contracted to a four-month low of 0.1 per cent in November due to poor performance of manufacturing and mining sectors, and declining production of capital goods.
Brokers said the market heavy and second largest software exporter Infosys recorded its biggest ever rise of almost 17 per cent to Rs 2,712.60 on higher revenue guidance remained a lone feature of the trading.
They said despite weakening trend in the overall trade, stocks of IT companies and consumer durables remained in the lime-light.
"The industrial production declined to a negative 0.1 per cent in November from a year earlier. This dampened the positive spirit of the market and selling pressure was seen across all major sectors, with the exception of IT and Technology, said Rakesh Goyal, Senior Vice President, Bonanza Portfolio Ltd.
The IT sector index gained the most by rising 9.34 per cent to 6,252.26 as Infosys shot up by Rs 392.25 to Rs 2,712.60, Tata Consultancy by Rs 47.80 to Rs 1,306.35 and Wipro by Rs 24.10 to Rs 419.50.
Infosys, the first Sensex company to begin earnings season for the December quarter, increased its sales forecast about three per cent to Rs 40,746 crore and reported net profit of Rs 2,369 crore.
The major market pullers were Reliance Industries, Bajaj Auto, Tata Motors, BHEL, ICICI Band, State Bank of India, ONGC Tata Motores and Tata Power with their steep losses.
