Currency impact on equity allocation is now extreme
The strength of the US dollar has hugely overstated the attractiveness of US equities to both US and international investors. The currency effect against developed markets is more powerful than it has been in all but 3% of weekly observations, going back to 1995. This is fine while it lasts, but one day it will go into reverse. Meanwhile, the dollar index is approaching generational highs. After the last tech-bust and peak dollar, US equities underperformed the rest of the world, in dollar terms, for the next five years (2003-08).
