U.S. stock futures were higher earlier this morning, as stocks seemed intent on extending Monday's gains. Investors were encouraged late Monday by some good news impacting bond insurers, but economic data, as well as several companies reporting earnings, may yet change that mood.

On Monday, stocks advanced after Standard and Poor's affirmed its AAA rating of troubled bond insurers MBIA (NYSE: MBI) and Ambac (NYSE: ABK). MBIA also announced late Monday it a plan to stop paying quarterly dividends. The Dow industrials surged 189 points, or 1.53%, the S&P 500 added 18 points, or 1.38%, and the Nasdaq Composite rose 24 points, or 1.05%.

At 10:00 a.m., the Conference Board will report consumer confidence For February, which economists project dipped to 82 from 87.9 in January.

Several companies report earnings today including Target (NYSE: TGT) and Macy's (NYSE: M).
