"Personally, I haven't played a video game since college; but I know the video game market is red hot," says Alex Green; here, the investment director for The Oxford Club takes a look at GameStop (NYSE: GME).

"With more than 5,100 stores throughout the United States and 15 other countries, GameStop is the world's largest video game retailer.

"Its stores include GameStop, EB Games and Electronics Boutique. It also publishes Game Informer, the industry's largest circulation video game magazine with more than 2.2 million paid subscribers.

"Finding its way onto the short-term bullish list is discount retailer Costco Wholesale (NASDAQ: COST), our 'focus stock of the week'," says Chris Johnson in his contrarian advisor service, Insightful Investor.

"The warehouse giant is currently seeing a positive mix of technical strength along with growing pessimism that makes it a potential outperformer. Costco is one company that has maintained a level of demand not seen throughout the bulk of the retailing sector.

"COST's core business, which caters to small businesses and households willing to buy in bulk, has maintained strength despite the slowing economy. In fact, the company's latest earnings report, released March 5, beat analyst expectations by 23%.

"Reflective of its fundamental strength, COST's stock price has remained a relative strength leader by trading above its 50-day moving average. The equity has outperformed not only most of its peers in the retail group, but the overall market as well.
