Shares of Take-Two Interactive ( TTWO) sank in late trading Thursday after the video-game publisher reported a wider-than-expected second-quarter loss amid rising product costs and a huge write-off.

For the quarter ended April 30, Take-Two posted a loss of $50.4 million, or 71 cents a share, widened from $8.2 million, or 12 cents a share, a year ago. The bottom line included a charge of 24 cents a share related to restructuring. Without that charge, the company still would have recorded a loss of about 47 cents a share. Analysts polled by Thomson First Call had predicted the company would post a loss of 11 cents a share before the charge. The wider loss came even as sales jumped 19% to $265.1 million, topping Wall Street's estimate of $258.8 million. Take-Two shares dropped $2.27, or 13%, to $14.50 in after-hours trading.

Shares of Quality Systems ( QSII) surged after the health care information-systems company beat Wall Street's fourth-quarter earnings estimates. The company posted earnings of $7.6 million, or 28 cents a share, for the quarter ended March 31, topping analysts' average forecast of 23 cents. A year earlier, the company earned $4.8 million, or 18 cents a share. Revenue climbed 39% to $35.6 million, compared with Wall Street's target of $33.2 million. Shares jumped $3.15, or 10%, to $35.15 in late trading.

Quiksilver ( ZQK) shares rose after the outdoor-sporting-goods company matched Wall Street's second-quarter earnings expectation. For the quarter ended April 30, the company reported earnings of $3.7 million, or 3 cents a share, down from $34.7 million, or 28 cents a share a year ago. The company's results included the Rossignol and Cleveland Gold businesses, which were acquired in July 2005. Rossignol's business is seasonal, and hurt the company's second-quarter results, Quiksilver said. Revenue increased to $516.9 million from $426.9 million. Wall Street was looking for earnings of 3 cents a share on revenue of $527.3 million.
