NEW YORK -- The Standard & Poor’s 500 index is trading above 1,500 for the first time since December 2007.

The S&P has risen for the past six days. Thursday’s gain followed a sudden drop in claims for unemployment benefits, another sign that the labor market is healing.

A plunge in Apple’s stock pulled the Nasdaq composite index lower. The electronics giant predicted slower sales.

The Dow Jones industrial average was up 69 points at 13,849. The Standard & Poor’s 500 index inched above 1,500 in early trading, and was up four points at 1,499 as of 10:15 a.m.

The Nasdaq fell nine points to 3,144. A sharp drop in Apple, one of the country’s most valuable companies, is enough to pull down the technology-heavy index.
