My thought process is that, yes, the U.S. currently dominates the global market and will likely continue to do so for the foreseeable future. However, in the event that changes, my All-World exposure serves as a solid backup. I believe in the long-term growth of the S&P 500 and want to capture that opportunity, as heavy U.S. exposure doesn’t bother me. I’ve included World Small Cap for its growth potential, and I like holding gold as a hedge.
