Advanced Micro Devices Inc. Amid After-Hours Losers Monday

With the benchmark NASDAQ Composite

falling Monday to 8.6 percent below its high of last month, a number of its higher-profile components notably underperformed Monday in the extended session on little discernable news. Advanced Micro Devices Inc.

plunged more than 7 percent in the extended session, changing hands recently at $2.56 a share, after closing Monday little changed. Advanced is slated to post earnings Thursday, a week after Chief Executive Chief Executive Rory Reade quit. GoPro Inc.

dropped nearly 10 percent in Monday's session to $76.67 a share, falling a further 2 percent after hours. GoPro's decline came amid reports that Michael Schumacher, a former race car driver, sustained brain injuries wearing the company's camera while skiing last year season in France. Tesla Motors Inc.

lost 5 percent at closing and continued to falter by nearly a point in the extended session. The shares are off more than 20 percent from their peak last month. Twitter Inc.

closed down Monday nearly 4 percent at $48.49, falling a further 0.8 percent in the extended session recently. The shares are down nearly 10 percent in the past week, which included the departure of a high-profile news executive. Google Inc.

closed down nearly 2 percent and was off a further 1 percent after hours Monday, even as rumors suggested the unveiling of its Nexus 6 smartphone may happen later this week. Dennis Dick, host of Benzinga's #PremarketPrep show and Proprietary Trader at Las Vegas-based Bright Trading LLC. said Advanced Micro, Twitter and Google "all had serious institutional selling pressure" Monday. Dick said Advanced Micro "dropped nearly 20% after hours" and after hours selling was relentless."
