Before the bell: Stock futures higher as earnings mostly top estimates


U.S. stock futures edged higher Tuesday morning, indicating stocks are poised for a mildly positive open. This comes a day after U.S. markets set new 2009 highs and following solid results from Apple and Texas Instruments late Monday.

Tuesday, investors will watch for a flood of earnings from such heavyweights as Coca-Cola, Pfizer and DuPont. In addition, some economic releases are scheduled for this morning, including inflation and housing data.
