My point is simply a tautology: the price is the price. Now the price may change, someone may have their thumb on the scale, there may be shill bidders driving sentiment, etc. But at the moment you get a bid/ask spread, that is what you get.
Practically speaking, I personally don't believe the efficient market hypothesis due to the very obvious meddling by political actors, central banks, national treasuries, etc. Behavioral finance has also consistently demonstrated that humans do not react rationally in markets.
That may have been your point, but it's not what you said. "Perfectly valued" means that the price is what it should be (for some definition of "should").
"Perfectly valued" to me means that at that moment, the price reflects the actions of everyone. It includes the actions of all buyers/sellers who choose to participate and not participate, the regulators, as well as the meddlers.
My point is a pedantic one referring to the OP using the word "overvalued". The market price is never over/under valued. It is merely the market price at that moment.
