The question links a conditional variance value to a claim about the conditional mean of tomorrow's return, so we should unpack what variance tells us and what it does not. Option 1: "Make sense". This would imply that knowing Var_t(R_{t+1}) = 0.0004 directly pins down the conditional expectation to be......Login to view full explanation
