Then, we check the load of each component of the volatility - accounting component or economic component - on the predictability of earnings. Our results confirm our prediction, ie the presence of a negative relationship between volatility and the predictability of earnings. Nevertheless, this capacity decreases with the presence of the extreme values of earnings
