NEW YORK (AP) --- U.S. stock indexes are mostly lower in early trading, but Amazon soared after reporting a surprise profit.

With corporate earnings in full swing, several big companies were making sharp moves Friday after reporting their results.

Most notable was Amazon, which jumped 17 percent after surprising investors with a profit.

Elsewhere, Capital One sank 10 percent and Biogen plunged 17 percent after their results fell short of what analysts were expecting.

The Dow Jones industrial average was down 20 points, or 0.1 percent, to 17,712 as of 9:35 a.m. Eastern time.
