The Nasdaq slipped and the broader market struggled Thursday after comments by the chief executive of troubled mortgage lender Countrywide Financial revived investor worries about the turmoil in the credit and mortgage markets. Stocks rose early in the session after Bank of America said it was making a $2 billion investment in Countrywide Financial. However, gains were short lived, with stocks falling by late morning. Countrywide's chief executive said in a television interview in the late morning that there is still a big liquidity problem and that the housing slump could lead the U.S. economy into recession. Meanwhile, the Congressional Budget Office (CBO) said Thursday that the U.S. budget deficit will shrink more than expected this year, due to a reasonably strong economy. However, the CBO voiced uncertainty about the future because of the housing slump. In economic news, a morning repot showed that the number of Americans filing new jobless claims fell last week by a smaller-than-expected 2,000 to 322,000. Separately, mortgage lenders cut 18,000 jobs this month, reflecting the fallout from the high-risk “sub-prime” lending market.
