The National Association of Realtors' index for pending sales of existing homes rose in February at a seasonally adjusted annual rate of 0.7 percent.

The home sales report, the primary catalyst driving up stocks Tuesday, was not especially robust, but the market has been hungry for some decent news on the housing front to suggest that the broader economy is impervious to the financial problems of subprime lenders, companies that make loans to people with poor credit.
While Tuesday's stock gains were strong, the market remains vulnerable; the subprime lending market is still shaky, and earnings season is less than two weeks away.
"I don't think we're out of the woods yet," said John O'Donoghue, co-head of equities at Cowen & Co., noting that some of the market's gains were probably due to frustrated traders short-covering, or buying back bets that prices would fall. "The market has exhibited a certain amount of complacency. We'll see how earnings come in."
Investors are treading fairly optimistically toward the first quarter earnings season. So far, there have been a few profit warnings notably from a few homebuilders but some investors had braced for more dire earnings preannouncements.
