We can see that Russia is extremely cheap, so it might make sense to place some small amount of our investing money in a Russian ETF, such as RSX. As you can see this ETF as biased towards the energy sector. Another option could be RSXJ (Small caps) and less oil and gas, obviously.
Russia is a risky country and its currency has suffered a huge decline in the latest years, therefore only expert investors who know how to manage their risks should think of this market. But also, remember, that buying stocks of a "safe" country at desorbitan prices can be as risky, if not more, as Russia.
