SiRF: Another Rough Quarter Sends Stock Tumbling

GPS chipmaker SiRF Technology Holdings (SIRF) is taking a bath following another rough quarter. For Q2, revenue totaled $63.1 million, which was actually above the consensus of $62.1 million. But the company posted a non-GAAP loss of 19 cents a share, worse than the 13-cent loss the Street had expected.
