I came across an article this week through the online site Seeking Alpha (written by "The Ox") which describes the five "most-hated" ETFs that might well have upsides for investors and advisors.
I like having at least one of these types of investments in our portfolios. They can add convexity to returns, since the downside of beaten down sectors such as these are often pretty low, especially compared to their upside if they transform into "swans."
My choice from these five are Japanese stocks. I like their proximity to China, but prefer large-cap issues that do a lot of exporting, as opposed to smaller-cap names (even though the latter are cheaper from a valuation standpoint).
