U.S. equity markets have dominated their international and emerging market counterparts over the past 10 years. That doesn't mean it's time to give up on international stocks.

International markets have similar long-term performance to the U.S. market and provide uncorrelated returns for a smoother investment experience.

Watch the video below to see why it's important to maintain international exposure in your investment portfolio, despite its recent performance.
