Consider the following information concerning three portfolios, the market portfolio, and the risk-free asset: Portfolio RP ?P ?P
X 14.50 % 35.00 % 1.30
Y 13.50 30.00 1.25
Z 8.40 20.00 .90
Market 11.60 25.00 1.00
Risk-free 6.00 .00 . 00
Assume that the tracking error of Portfolio X is 9.30 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.)
