Stocks poised for a weaker start after Monday's rally

It was to be expected that a day after Wall Street's big rally -- biggest since November -- U.S. stock futures would be lower, pointing to sluggish start for stocks Tuesday morning. If on Monday investors welcomed the administration's plan to buy toxic assets from struggling banks, today they would tune into testimony about AIG.

Treasury Secretary Timothy Geithner and Federal Reserve Chairman Ben Bernanke are testifying later today before the House Financial Services Committee on the bonuses paid to American International Group (AIG), but after discussing that, they may also be grilled on the new risks to taxpayers from the latest plan unveiled Monday to take over up to $1 trillion in dodgy mortgage securities with the help of private investors.
