U.S. financial markets’ premium valuations are often called “U.S. exceptionalism.”
U.S. GDP growth, high corporate profits and an appreciating currency have long drawn more global capital flows than other economies attract.

A relative shift in economies’ outlooks could spur asset allocation rebalancing globally.
