Stock A pays 30% in a boom, 10% in a normal economy, and -30% in a recession. Stock B pays -15% in a boom, 0% in a normal economy, and 20% in a recession.

Enter your answer as a percentage point without the % sign, and round it to the second decimal point (i.e., if the answer is 10.3456%, enter it as 10.34).
