Thornburg May Be Forced Out of Business

``Shares in jumbo mortgage lender Thornburg Mortgage Inc. lost more than half their value Monday after the company said a spike in margin calls could force it out of business.... The lender is most likely going to have to sell assets at a discount to raise the $270 million, as the tightening credit markets would make it extremely expensive to raise new capital through a debt offering, George said.'' -- which of course will make the market worse.
