That actually reinforces my point. For bubbles to occur, the delta between the price and the “rational” price must not be random. In bubbles prices exhibit strong temporal autocorrelation.

Assuming bubbles are real, which is somewhat unprovable. There are careful ways to falsify different formulations of the EMH.

"Bubbles" is not one.
