economies growing far faster than our own - there may not be enough
historical data to back test this in Firecalc, but it may be that going forward well diversified portfolios with international component will return more than one based solely US stocks and bonds.
Yes, and these international investments have been available to their country residents for as at least as long as U.S. investments have been to U.S. residents. You could get some feel for the diversification by reading "Triumph of the Optimists" by Dimson & Marsh.
They may not necessarily return more but they may be less volatile.
Do us a favor-- if you have more on this subject, please start a new thread in "FIRE & Money" and limit this thread to a "Hi, I am..." introduction.
