Vote Now! Apple vs. BlackBerry in Squawk Box Money Madness Final

Investors can be a finicky bunch and few stocks illustrate the point better than Apple and BlackBerry.

In Apple's run-up to record highs in 2012, the stock peaked back in September at more than $700 a share. That was a 68 percent increase before it started to nosedive—dropping 20 percent by the end of the last year and another 20 percent so far in 2013.

Meanwhile, BlackBerry's continued its slide for most of 2012—bottoming out at around the same time Apple peaked before recovering into year end. And that BlackBerry comeback carried over into the new year with shares rocketing up 46 percent in just the first few weeks in 2013 before cooling off somewhat.
