Unnatural would be prices not supported by future cash flows, or prices that are not typical of historic norms based on concrete measurements such as profit, revenue, or growth. I take your point that pricing is arbitrary, particularly moment to moment. But economics theory dictates that all the arbitraryness resloves or cancels out into an efficient finding of price.
