Spanky: Thanks for the websites! I called Schwab yesterday and found there's another good website for ETF's: www.amex.com
. This site also has extensive ETF listings in all of the major categories as well as detailed info such as expense ratios, investment returns, holdings, dividend histories, etc. for each ETF.
Hyperborea: I re-read the article and I think you're right that Siegel considers the S&P Global and the DJ Global Ttans indexes to be primarily investments for the U.S. portion of one's portfolio, seeing that a lot of the companies in these indexes are American- like GE, XOM, MSFT, AIG, JNJ, PG, etc. - stuff that I already hold as individual stocks in my own account.
On the other hand, I have an acquaintance, an elderly man that I met at Schwab, about 12 years ago. We get together every so often to talk about finances, investments, and the economy in general. This man, who has been living off his investments for many years, does not have a pension due to working only a limited number of years for some company in the remote past. It seems the bulk of his investments are in large, dividend-paying U.S. stocks. He is the first and only FI/RE person I have personally met and known. He is a voracious reader of Barron's, Forbes, WSJ, etc. and is a much more knowledgeable and sophisticated investor than I am. One day I asked him what he thought about international mutual funds and foreign ADR stocks. He said, as far as he is concerned, he gets all the foreign exposure he needs through his positions in the large multinational U.S. stocks he holds. So, this is where I got to thinking that the aforementioned Global Indexes could be considered "additional international exposure".
