:it means market efficiency can only be jointly tested what a given model of equilibrium expected returns.
-This means that we can't ever be sure what the correct model of expected returns is.
-In other words, we can only decide if markets are efficient if we assume that we know what risks investors care about, and how they are priced.
-There are lots of models of expected returns, and we don't know which one is correct. Ex. CAPM, fAMA French, Liquidity, Macro risk, Beta.
-We can only say that he market is or isn't efficient with respect to that model, but we can't say overall whether the market efficiency is independently true
