Consider the following information concerning three portfolios, the market portfolio, and the risk-free asset:

Portfolio	Return of p	Standard Deviation of p	Beta of p
X	15.50%	36.00%	1.35
Y	14.50	31.00	1.15
Z	7.40	21.00	.60
Market	11.70	26.00	1.00
Risk-Free	7.00	.00	.00

Assume that the tracking error of Portfolio X is 10.70 percent. What is the information ratio for Portfolio X?(Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 4 decimal places.)
