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.
