I took a quick look at the major US companies. I simply went at Google Finance and calculated FCF, deducting Capital Expenditures from Cash from Operating Activities. The results are listed below.
My feeling is that US market is very attractive, considering the excellent worldwide companies we talking about, historical low rates, great country, and so on.
Or, on the other hand, we can say Brazil isn't that cheap as they usually say.
It's amazing to see that great companies, most of them with a stable and somewhat growing cash flow, being traded by a nice yield.
