I'm Up 370% on This Under-The-Radar Stock, and I'm Not Selling

Most of your portfolio's returns will be driven by the minority of your stock picks, so a willingness to hold on to your winners long-term can help you beat the market. For example, I'm up more than 370% on Align Technology (NASDAQ: ALGN), and following its third-quarter earnings, I still don't have plans to sell my stock anytime soon.

For years, orthodontists have relied upon traditional metal braces to straighten teeth, but increasingly, they're adopting Align Technology's Invisalign, a transparent straightening system that's fueling significant top- and bottom-line growth.
