Intel also had a negative reaction to its first-quarter report, despite reporting solid earnings. The world's largest chipmaker reported non-GAAP earnings of 56 cents a share, on revenue of $12.9 billion for the first quarter. Analysts surveyed by Thomson Reuters were expecting EPS of 50 cents and $12.84 billion in sales. Second-quarter guidance was higher than anticipated, but margins are expected to fall quarter over quarter, and that caused pressure on the stock. For the second quarter ending in June, Intel expects revenue of $13.6 billion, plus or minus $500 million, and margins between 62% and 63%, down from 65.1% in the first quarter. Wall Street estimates call for $13.45 billion in revenue. Intel shares ended the week down 1.74% at $27.60.
