lululemon athletica (LULU 0.80%), which started out as a Canadian yoga-wear seller and has expanded to fitness gear around the world, has had an impressive run since March 2009.  The company has expanded to more than 280 stores worldwide, and its stock has appreciated more than 2,900% since then.

But even though the company's recent earnings report beat expectations, the stock is down significantly since CEO Christine Day -- who has been at the helm for all of this wild ride -- announced she'll be leaving the company once a replacement is found. 

In the following video, Fool contributor Brian Stoffel discusses why he thinks shares of Lululemon stock are worth looking into, given today's prices.
