The SPDR S&P 500 Trust (SPY) trades at a P/E (trailing 12 months) of 18.64 and a P/B of 2.7. The average P/E ratio since the 1870’s is roughly 15, while the current P/B is higher than 82% of the bull market tops since the mid-1920s.

Although several may try to describe the U.S. stock market as “fairly priced,” value-oriented investors recognize the lofty premium for what it is. Specifically, zero percent interest rates, deficit spending and trillions of electronically created dollars have enriched the lives of shareholders and property owners at the expense of interest-income savers. In fact, many might argue that these policies also encouraged corporations to borrow cheaply, buy back their own stock shares and limit meaningful job hiring. Indeed, approximately 95% of Americans have been unable to increase their inflation-adjusted household income since the Great Recession ended in June of 2009.

Valuation headwinds notwithstanding, the world’s money continues to pour into the North American equity space. Exchange-traded funds with a North American focus raked in $14 billion in the week ending November 7. In contrast, developed Europe and Asia-Pacific were net losers in fund flow – $1.5 billion in outflows for each region.

If money is moving out of Europe and out of Asia-Pacific, might it have anything to do with valuation concerns? Hardly. Vanguard Europe (VGK) offers a more reasonable P/E of 16.5 and a more seductive P/B of 1.7. The iShares MSCI Asia excl Japan Fund (AAXJ) boasts a P/E of 12.4 with a tantalizing P/B of 1.4.

In truth, the reservations that investors have with countries outside the U.S. rest primarily with the global growth slowdown as well as an uncertainty that foreign central banks (e.g., European Central Bank, People’s Bank of China, Bank of Japan, etc.) can do enough to strengthen respective economies. There’s also the strength of the U.S. dollar. Investing in foreign equities will require some faith in a stabilizing euro and a stabilizing yen. Both CurrencyShares Euro Trust (FXE) and CurrencyShares Yen Trust (FXY) demonstrate that stabilization may not happen anytime soon.
