As an investor, it’s important to keep track of big, demographic shifts. Truly, that’s where the money is. It is hard to time these trades because one day they’re not important, and then suddenly they are. I’ve never had much success trading on demographics—at least until recently. You see, if you’re going to invest in something like the WisdomTree Japan Hedged Equity Fund (DXJ), you have to understand Japan demographically and culturally.
