Subject: Foreign exposure
"Why is the US market expensive? The simplest response is "prices fluctuate". There has been almost no penalty for buying dips for a long time, so the market ratchets upwards till something breaks. More subtle answers come from macroeconomics: other things being equal, or even approximately equal, it's pretty much an identity that a rising government deficit will cause corporate profits to soar, which of course causes people to want to own more equities... The S&P 490 (all but big 10) manages to produce only 2/3 of the total S&P 500 profits."

"Investors hate international stocks, emerging market stocks and value stocks for a reason. The companies at the top of the S&P 500 and Nasdaq 100 are, frankly, better businesses. They’re outperformed in the stock market because they’ve outperformed on business fundamentals. Maybe large cap growth now has overtaken what was the small cap value premium in the past."
U.S. stocks have gained profit share along with market share. US as % of Global: Profits 55%, Market Cap 65%.
