Earlier this week, I penned an article that questioned whether investors could achieve the benefits of low correlation in their holdings by owning shares of foreign companies in concert with domestic stocks. My conclusion was that it is increasingly difficult to benefit from foreign exposure because of synchronization of world economies.
It may no longer be sufficient to buy a couple of European stocks or a foreign fund to be considered internationally diversified. This is not to say you should avoid these areas necessarily but simply that stocks such as AstraZeneca
One way to diversify internationally is with emerging markets. But in that same breath (or at least the next one), I should mention that while emerging markets' volatility should partially offset, or at least buffer, the volatility of our own market, emerging markets come with their own set of unique risks, some of which are much greater than the risks inherent in industrialized country investments.

Often companies from emerging markets have low valuations and good dividend yields -- benefits of the low prices the market gives these companies on account of their increased risk.
There are specific names I've come across that are tied to the three countries mentioned earlier: Petroleo Brasiliero
While any of these companies could take a hit, it won't be on account of a speculative valuation. But if emerging markets are not your cup of ramen, then there is another way to add international diversity to your portfolio.
