US futures rise as more US companies show health

(AP) U.S. stock futures are heading higher as markets focus on the health of U.S. corporations.

Dow Jones industrial futures are up 37 points to 13,104 and the broader S&P futures added 5.4 points at 1,395.30. Nasdaq futures are up 16 points at 2,702.50.

CVS Caremark on Tuesday posted an 18 percent spike in second-quarter net income as new business and an expansion of its pharmacy benefits management business boosted revenue. The drugstore chain operator's adjusted earnings beat Wall Street expectations.

Disney, Priceline and Express Scripts, which just ended an extended contract dispute with CVS rival Walgreen, will all report earnings after the closing bell.

Also Tuesday, the Federal Reserve is expected to report that U.S. consumers likely took on more debt in June, even as they largely kept spending in check.
