The argument that the US stock market always goes up over relatively long periods of time seems somewhat flawed to me. If it were true that it was always best to invest in US stocks, everyone’s (longish term) money would flow to that asset class, thus undervaluing something else in return. So it just seems that it can’t be a dominant strategy or else everyone would be doing it. Wouldn’t that leave assets like bonds, real estate, foreign stocks, etc undervalued?
