This is true! Most money can be made where no one is looking that closely :) but of course there is a larger risk for smaller companies and single, rather developing countries (expect for maybe the US which is hard to hit hard without also affecting any other market)
Well, it is natural because those countries have a lot higher risk profile. Meaning, their stocks could make 2-3 extra percents per year but this is the price of risk of something really bad when they go to zero, say Taliban takeover, or Communist revolution, or a hot war with India...
And yet it's the US that has >5% inflation rate and the long bond around 1%. Every country can become a banana republic, you know.
Also, I agree with the consensus on the risk level ordering, but it's not just the risk, it's the reward too. High priced securities offer no (or even negative) reward in the optimistic outcome scenario.
