Subject: Re: Foreign exposure
Is it dark for foreign markets? In my opinion, it could very well be.

Maybe?
From Vanguard ETFs:
S&P 500 (VOO) has a P/E of 28x, earnings growth of 20%. Rest of US (VXF) at 22x and 16%, Rest of world (VXUS) at 15x and 15%. Blithely assuming the growth rate materializes forever, the payback periods (when you get back $1 in earnings for $1 price today), are 10 years for S&P, 10 for rest of US, 8 for RoW.
Inflation can be ignored assuming earning yields are approximately real.

All math aside, foreign companies that pay regular dividends, have a boring business, and are in somewhat business-friendly and shareholder-friendly-ish jurisdictions, are good enough for me. Nestle, Roche, a few large ones in the FTSE UK index, etc.
