The same people that say this are in the markets. They just want to short them.
How much of this is fodder for the AI traders?
Yessir...that's exactly what is going on. It's too hard to make money the honest way.
Yes, if you have enough money you can buy “shorts” which amounts to insurance if low expectations are realized. It is a false premise to suggest because of that the markets are not over valued and THE ONLY purpose of suggesting is is because you’ve been fortunate enough to take out some insurance, should you be proven right.
Go ahead an keep holding.
