Suppose Intel stock has a beta of $0\mathrm{.}74,$ whereas Boeing stock has a beta of $1\mathrm{.}17.$ If the risk$-$free interest rate is $6\mathrm{.}3\%$ and the expected return of the market portfolio is $13\mathrm{.}8\%,$

according to the CAPM,

a$.$ What is the expected return of Intel stock?

b$.$ What is the expected return of Boeing stock?

c$.$ What is the beta of a portfolio that consists of $60\%$ Intel stock and $40\%$ Boeing stock?

d$.$ What is the expected return of a portfolio that consists of $60\%$ Intel stock and $40\%$ Boeing stock? $($There are two ways to solve this.$)$

a$.$ What is the expected return of Intel stock?

Intel's expected return is

$\%.($Round to one decimal place.$)$ The return of stock B is $\%.($Round to two decimal places.$)$ The variance of stock Ais $($Round to five decimal places.$)$ The variance of stock B is $($Round to five decimal places.$)$ The standard deviation of stock A is $\%.($Round to two decimal places.$)$ The standard deviation of stock B is $\%.($Round to two decimal places.$)$
