People have been asking Motley Fool CEO Tom Gardner one question a lot lately: Why haven't you sold your Motley Fool Stock Advisor shares of Netflix (Nasdaq: NFLX)? With the stock up more than eight times since Tom's recommendation -- and more since David Gardner first picked it at Stock Advisor -- one can understand the curiosity of profit-minded investors. But, as Tom explains in this video, there's more to valuing a stock than, well, valuation. He urges investors to take a 360-degree view of the companies they own and to evaluate a firm's leadership, culture, and brand before pulling the trigger to sell.

Tom Gardner does not own shares of Netflix but has recommended the stock -- along with David -- through Motley Fool Stock Advisor. Try any of our Foolish newsletter services free for 30 days.
