Of course, most of us can' t really make sensible investment decisions when it comes to picking stocks on the Frankfurt or Tokyo stock exchanges. So the best way to include some global stocks is with a mutual fund. Think small, too. Every big company once started out as a small company. If you can buy good companies when they're small, you'll benefit as they get to be big and successful companies.
Trouble is, lots of small companies just get smaller and eventually go out of business.
So small company stocks tend to be a little risker than big stocks. And vice versa. So if you own big and little companies in you portfolio, over the long-term, things will more than balance out in your favor. Little US stocks. Big foreign stocks.
