U.S. stocks fluctuated, after two days of declines, amid quarterly results from Regeneron Pharmaceuticals Inc. to Allstate Corp. while Apple Inc. slipped further into a correction.
Allstate lost 10 percent as the insurer's profit plunged on a surge in auto claims. CVS Health Corp. fell 1.4 percent after narrowing its earnings forecast. Apple sank 2.2 percent to a six-month low. Regeneron and Sprint Corp. gained more than 5.3 percent as their earnings exceeded analysts' forecasts. Baxalta Inc. surged 14 percent after Shire Plc offered to buy the company for about $30 billion.
The Standard & Poor's 500 Index lost 0.1 percent to 2,095.06 at 3:04 p.m. in New York, after falling as much as 0.5 percent. The Dow Jones Industrial Average lost 36.72 points, or 0.2 percent, to 17,561.48. The Nasdaq Composite Index was little changed.
"There's some concern over Apple -- it's a big stock that has a big impact on all the indexes," said Randy Warren, who manages more than $100 million at Exton, Pennsylvania-based Warren Financial Service & Associates Inc. "We've seen a lot of companies struggling this earnings season. There are a lot of global growth concerns out there."

Analysts now forecast a 2.8 percent drop in second-quarter earnings, shallower than calls for a 6.4 percent fall about three weeks ago.
"When investors look at the tail-end of earnings season, you've had some companies come out and disappoint, and they've been punished for it," said Bill Schultz, who oversees $1.2 billion as chief investment officer at McQueen, Ball & Associates Inc. in Bethlehem, Pennsylvania.
