Consider the multifactor APT with two factors. Stock A has an expected return of $18\mathrm{.}70\%,$ a beta of $1\mathrm{.}2$ on factor $1,$ and a beta of $0\mathrm{.}6$ on

factor $2.$ The risk premium on the factor $1$ portfolio is $4\mathrm{.}00\%.$ The risk$-$free rate of return is $7\mathrm{.}60\%.$

What is the risk premium on factor $2$ if no arbitrage opportunities exist?

Note: Round your answer to $2$ decimal places.
