with a beta of $2\mathrm{.}11$ you also invested $$20,000$ in Macy$$s$.$ For your last selection you have a

couple to choose from: Disney with a beta of $1\mathrm{.}20,$ the Boston Beer Company $($Sam Adams$)$ with

a beta of $0\mathrm{.}73$ and Boeing with a beta of $1\mathrm{.}83.$ You would like the overall beta of your portfolio to

be as close to $$the market$$ or $$average stock$$ as possible. Make your third selection and
