NEW YORK, Sept 30 (Reuters) - U.S. stocks were poised to rise at the open on Tuesday, clawing back from Wall Street's worst slide in more than 20 years, as investors bet that Washington will work to revive a plan to stabilize the U.S. financial system.
The House of Representatives rejected the proposed $700 billion rescue plan on Monday, but investors held out hope that leaders in Washington might work around any disagreements.
Still, signs of mounting strains in the credit markets fueled caution after overnight dollar interbank lending rates hit their highest in at least 7-1/2 years, suggesting banks continued to horde cash amid a lack of confidence. For details, see [
]U.S. President George W. Bush said the legislative process on the bailout plan was not over and the economy depended on "decisive action" from the government. For details, see [
]The surprise defeat of the plan rattled markets around the globe, with Asian stocks following Wall Street's Monday slide overnight. European shares gave up gains on Tuesday after Bush's remarks and awaited news on the bailout plan.
"There's an overarching belief that at some point this week, whether it's Wednesday or Thursday, we'll get something passed by the House," said Arthur Hogan, chief market analyst at Jefferies & Co in Boston.
"At the same time, the market is coming to the realization that this rescue package, in whatever form it comes out, is not going to cure everything. It's not going to cure a slower economy or force banks to lend to each other. We're going to fix one problem but we're still in a slow economy."
S&P 500 futures <SPc1> rose 21.40 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures <DJc1> climbed 124 points and Nasdaq 100 <NDc1> futures added 18 points.
According to Thomson Reuters weekly 14-day relative strength chart data, the broader market -- as measured by the S&P 500 <.SPX> -- will start Tuesday's trading at its most oversold level since July 2002, right before the start of the last bull market.
Hogan said he expected gains to be tentative until there was clarity from Washington. He added bargain-hunting was likely to underpin the market on Tuesday. Trading may be light with many market participants away from their offices for the Jewish New Year holiday on Tuesday and Wednesday.
In economic news, the S&P/Case-Shiller Home Price Index showed further deterioration in housing, with prices of single-family homes plunging a record 16.3 percent in July. [
