When you say 'random' you probably mean that market prices are a Martingale? See https://en.wikipedia.org/wiki/Martingale_(probability_theory...
That's very, very related to being efficient.

“No, not at all”.
The “weak version of EMH” has nothing to do with markets being “efficient”, it's a property of random markets. Assimilating the two just Fama's motte-and-bailey fallacy.
