Coldwater Creek ( CWTR) was among the losers in a generally mixed post-close session Thursday. Shares plunged 15.4% after the women's-products retailer forecast a fiscal third-quarter loss of 11 cents to 13 cents a share on $260 million to $265 million in sales. In February, it had projected a profit on significantly higher revenue. Analysts are looking for earnings of 14 cents a share, before special items, on $300.2 million in sales. As with many of its fellow retailers, the Sandpoint, Idaho-based company blamed its woes on declining store traffic as well as an "increasingly promotional environment." Fourth-quarter guidance was also slashed. Shares were sinking $1.67 to $9.20. Californian wireless-products maker CalAmp ( CAMP), meanwhile, said it swung to a continuing-operations loss of 14 cents a share. That's in line with two analysts' targets, but revenue dwindled some 40% year over year to $32.7 million, coming in just shy of estimates. Shares tumbled 61 cents, or 14%, to $3.75. Electronic Arts ( ERTS) of Redwood City, Calif., saw choppy trading after agreeing to pick up two game development studios, BioWare and Pandemic by buying VG Holding from Elevation Partners. The deal, worth up to $620 million in cash and as much as $155 million in equity, should close in January. Shares of the video-game publisher were recently up 19 cents to $58.88. Elsewhere, Threshold Pharmaceuticals ( THLD) halted enrollment in a midphase trial of lung-cancer treatment glufosfamide. The study yielded only one confirmed partial tumor response, said Threshold, falling short of the three-or-more threshold required for further enrollment. Shares of the California-based company lost 19.5% to 70 cents in light extended trading.
