Investors snapped up trust-preferred securities last week  after a rumor rumbled through the market that Congress may soon eliminate   the novel securities.   
Spreads on the issues tightened by 10 basis points on Thursday afternoon  and held strong into late market trading on Friday. 
  
But many observers were skeptical of the rumor, noting that Congress  adjourned in mid-November and won't reconvene until late January. 
"This sounds like a made-up story to push the market up," said bank bond  analyst Allerton J. Smith of Donaldson Lufkin Jenrette Securities. "We have   seen no indication that the Treasury Department plans to reintroduce   legislation that curtails trust-preferred issuance."     
  
The biggest holders of the securities include Goldman Sachs & Co., which  helped engineer the product; Morgan Stanley & Co.; and Fidelity   Investments.   
Either way, the securities retain worth, said Joseph Labriola, head of  corporate bond research at PaineWebber Inc. "If the window is shut the   securities offer value, if it remains open, they are still valuable   although not as much so." - Tania Padgett
