You are given the following information concerning three portfolios, the market portfolio, and the risk$-$free asset:

Portfolio RP $\backslash$sigma P $\backslash$beta P

X $14\mathrm{.}00\%31\mathrm{.}00\%1\mathrm{.}35$

Y $13\mathrm{.}0026\mathrm{.}001\mathrm{.}10$

Z $7\mathrm{.}0014\mathrm{.}000\mathrm{.}75$

Market $10\mathrm{.}2019\mathrm{.}001\mathrm{.}00$

Risk$-$free $6\mathrm{.}0000$

Assume that the tracking error of Portfolio X is $8\mathrm{.}60$ percent. What is the information ratio for Portfolio X$?($A negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to $4$ decimal places.$)$
