Priceline.com’s (NASDAQ: PCLN) stock continues to defy gravity and stay near the $800 level. Many skeptics have been asking how the stock can be this high with shares having risen 3,000% in the past eight years. The answer is that the company is the best in the online travel space. Priceline has successfully moved from being primarily a “Name Your Price” website to a fully integrated online travel booking destination.

…. Priceline is the better bet [compared with Expedia and Orbitz Worldwide]. It has the largest market cap, fastest quarterly revenue growth, highest operating margins, highest profits, and the lowest P/E. Based on these metrics, Priceline is the stock to own of the three.
