US stocks off to a mixed start

NEW YORK (AP) — Stocks are off to a mixed start on Wall Street as investors pore over a large batch of corporate earnings reports.

McDonald’s slumped 3 percent in early trading Tuesday, the biggest loss in the Dow Jones industrial average, after the hamburger chain reported disappointing sales growth in the U.S.

Biotechnology company Gilead Sciences dropped 7 percent after reporting weak sales and cutting its revenue estimate for the year.

The Dow edged up 11 points to 18,505.

The Standard & Poor’s 500 index was little changed at 2,171. The Nasdaq composite edged up 8 points, or 0.1 percent, to 5,106.

Bond prices barely budged. The yield on the 10-year Treasury note held steady at 1.57 percent.
