That seems to be directly the opposite of the common definition of the EMH, which emphasizes how the market reacts to new information. And not how it produces information. For example in TFA:

"the market rapidly responds to new information"

Wikipedia starts the "Theoretical background" with an example on how information becomes widely available to all investors, not how one fast smart thinker generates it:

    Suppose that a piece of information about the value
    of a stock (say, about a future merger) is widely
    available to investors.
