The Dow industrials rallied Tuesday as investors welcomed news that billionaire Warren Buffett has reached out to ailing bond insurers and major lenders have announced a plan they say will help U.S. homeowners avoid foreclosure. However, a technology advance lost momentum late in the session, leaving the Nasdaq virtually unchanged. Stocks rose for most of the session, with the Dow at one point up more than 210 points. But the market was unable to sustain gains in the afternoon, with the technology sector and commodity stocks turning lower. Wall Street reacted favorably to news that Buffett has offered to rescue the bond insurers and that delinquent homeowners might get some help from the major mortgage lenders. Specifically, Buffett, the chief executive of Berkshire Hathaway investment fund, has offered to insure about $800 billion in bonds. The offer was made to the three big bond insurers, MBIA, Ambac Financial, and FGIC. In economic news, the Federal Reserve (Fed) auctioned $30 billion in funds to commercial banks in the fifth in its series of auctions that have added $130 billion to the banking system.
