Mumbai: Ahead of the release of 2010-11 GDP estimates, the Bombay Stock Exchange benchmark Sensex on Monday slipped over 34 points or 0.19 per cent to 18,232.60 in lack lustre trading.

Similarly, the broad-based National Stock Exchange index Nifty fell by three points or 0.05 per cent to 5,473.10.

The BSE 30-share guage, Sensex, had gained over 114 points in early trade on news of early arrival of monsoon rains in Kerala.

However, lack of any major direction from global markets and profit booking by investors after last two-session gains of nearly 419 points pulled down the Sensex, brokers said.

"Market sentiment got a boost after reports stated that monsoon hit Kerala two days ahead of schedule," said IIFL Head of Research (India Private Clients) Amar Ambani.

However, the market was unable to find any specific direction throughout the day ahead of the quarterly GDP numbers to be announced on Tuesday.

The US and the UK markets are closed today. The Asian indices ended narrowly mixed while other European stocks were displaying a better trend in the mid-session trade.

Also, traders said several domestic factors would influence the market this week.

"Besides the GDP data, monthly auto sales, manufacturing PMI and exports figures during the course of the week would also play important market determinants," said Ambani.

Although the Sensex finished in the red, total market breadth was strong due to price rise in second-line stocks, pointing towards the increased retail participation.
