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

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

X $15\%32\%1\mathrm{.}4$

Y $14271\mathrm{.}1$

Z $9170\mathrm{.}75$

Market $10\mathrm{.}3221$

Risk$-$free $4\mathrm{.}200$

Assume that the tracking error of Portfolio X is $7\mathrm{.}4$ percent. What is the information ratio for Portfolio X$?($Round your answer to $4$ decimal place.$)$
