Amazon.com (NASDAQ: AMZN) — After reporting Q4 earnings that beat expectations but revenues missed by a small amount, AMZN sold off more than 9% in after-hours trading on Thursday.

This leading online retailer is expected to see a 28% rise in net sales in 2011, according to Standard & Poor’s, following the astounding rise of 36% in 2010. S&P said, “We consider AMZN a best-in-class retailer that generates significant free cash flow.”

The worldwide base of the company’s business model, along with a plan of continuous investments in long-term growth opportunities, sets it apart from the competition and makes it one of the best stock picks for investors and traders. 

AMZN is also a favorite of technicians and especially point-and-figure chartists like Dorsey Wright Associates of Richmond, Va., who has a target of $226 for the stock.

The sell-off on its earnings report makes AMZN a buy here for a trade to the top of the clearly established bull channel at $200, and is a long-term buy as well. Traders will want to place a stop-loss order at $170.
