AMD posts third straight quarterly loss, causing its shares to drop

Shares of Sunnyvale, California-based Advanced Micro Devices (AMD) are bucking the tech trend and falling, after the maker of personal-computer processors reported its third straight quarterly loss.

AMD shares fell more than 12 percent today after the company reported a loss of $330 million in its second quarter. Tech companies Apple (AAPL) and Yahoo (YHOO) topped expectations in earnings Tuesday and chipmakers Intel (INTC) and Texas Instruments (TXN) also beat estimates. But AMD is still fighting falling chip sales over the past year.
