Obviously I know. And so do you. Cause I did mention exactly that point to you a week ago.
(…though you would have already known or found out without me bringing it up, I’m sure 
)
Of course it’s not.
Now I certainly won’t be calling the valuation U.S. (especially tech) stocks a bubble to rival Japanese asset price inflation in the 1980. But the facts still remain:
- U.S. equity enjoys very high valuations, historically
- and it’s much higher valued than most of the (developed) world
Is it overalued? Or is the valuation justified? Why?
I am just advocating that - before putting more than half of one’s portfolio into that one market - one would maybe want to try to answer these question. To himself at least. Though I would (honestly) welcome opinions on the forum here.
I think there is a strong tendency in markets to revert to the mean, in the longer term. I also believe that U.S. economic dominance and the U.S. share of the total market cap won’t greatly expand above what it is today. If any, it might rather decline. This leads me to the conclusion that other markets might outperform U.S. equity in the future - though it won’t necessarily be today’s developed economies in the EU (with its problemativ currency) or Japan.
