Consider the multifactor APT with two factors. Stock A has an expected return of $21\mathrm{.}20\%,$ 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 $8\mathrm{.}60\%.$

What is the risk premium on factor $2$ if no arbitrage opportunities exist? $($Round your answer to $2$ decimal places.$)$
