Y	13		34		1.15
Z	8.5		24		0.9
Market	12		29		1
Risk-free	7.2		0		0

Assume that the correlation of returns on Portfolio Y to returns on the market is 0.9. What is the percentage of Portfolio Ys return that is driven by the market? (Round your answer to 2 decimal places. Omit the "%" sign in your response.)
