These Stocks Have Already Doubled -- but They're Still Crazy-Cheap

A lot of investors are frustrated with the stock market. Many of the most popular stocks in the market consistently trade at nosebleed-level valuations, making those who prefer the margin of safety that value investing offers uncomfortable.

Fortunately, there's more than one way to make money by investing in stocks, and those who like to invest in stocks at a bargain aren't out of luck. Below, we'll look at three stocks that still trade at levels that most value investors would consider crazy-cheap -- even though they've already doubled from where they traded just a year ago.
