A company$$s stock had a required return of $11\mathrm{.}50\%$ last year, when the risk$-$free rate was $5\mathrm{.}50\%$ and the market risk premium was $7\mathrm{.}45\%.$ Now, suppose there is a shift in investor risk aversion, and the market risk premium increases by $2\%.$ The risk$-$free rate and the beta remain unchanged. What is this company$$s new required return?
