This paper company is trading as low as it has in decades, but it faces an uncertain future.

Ahead of a two-day hearing on derivatives, a bond analyst is warning that a proposed House bill to ban speculation in the once-obscure securities would annihilate the $31 trillion credit-default swaps market.

Companies brought a near record amount of debt to bond markets in January, taking advantage of the thaw in investorsâ?? appetite for risk.

Among the companies expected to trade actively on Monday are three Dow industrials components -- Caterpillar, McDonald's and American Express -- plus Texas Instruments, all of which are scheduled to report earnings. Other movers include Covidien, Crucell, Danaher, Eaton, First California, Pfizer, Smurfit-Stone, Walgreen and Wyeth.

Shares of already-battered Smurfit-Stone slide further, falling more than 80% on media reports that the packaging giant may be on the verge of bankruptcy.
