New York - US stocks opened higher Friday helped by Procter & Gamble's 2.4 percent gain after it beat quarterly earnings estimates and raised its outlook for 2013.

Positive quarterly reports from Oshkosh (+14.8 percent) and Halliburton (+4.6 percent) also underpinned the fresh rally, while Microsoft slipped 0.4 percent on its middling results.

Five minutes into trade, the Dow Jones Industrial Average gained 30.10 points (0.22 percent) to 13,855.43.

The broad-based S&P 500 added 4.72 (0.32 percent) to 1,499.54, while the tech-heavy Nasdaq Composite rose 7.42 (0.24 percent) to 3,137.80. - Sapa-AFP
