The fall was also aggravated in absence of back-up buying by foreign funds and select unwinding by retail investors, as political uncertainty continued to haunt market participants.
In a volatile market on Thursday, the Sensex finished at 5,668.43 points down 44.66 points. The days low was 5,626.41 points. The broader S&P CNX Nifty lost 7.60 points to close at 1,808.95 points.
On Tuesday, the market lost 213 points on fears of economic reforms programme hitting a road block after the second phase of exit polls predicted that the ruling NDA coalition will be short of a simple majority, and that there is a possibility of a hung parliament.

Dealers said, the market undertone was weak since the beginning of this week amid fears of slowing of reform process, possibility of a hung parliament or following installation of an unstable government at the Centre.
On Thursday, the index heavy weight Reliance Industries lost ground despite the company posting a strong result. For the quarter ended March 31, 2004, the company posted a net profit of Rs 1,419 crore as against Rs 1,101 crore in the same quarter of last year.
