MetaSuppose that the index model for stocks A and B is estimated from excess returns with the following results:

RA $=3\%+0\mathrm{.}7$RM $+$ eA

RB $=2\%+1\mathrm{.}2$RM $+$ eB

$\backslash$sigma M $=20\%$; R$-$squareA $=0\mathrm{.}20$; R$-$squareB $=0\mathrm{.}12$

Assume you create portfolio P with investment proportions of $0\mathrm{.}60$ in A and $0\mathrm{.}40$ in B$.$

$1.$ What is the standard deviation of the portfolio? $($Do not round your intermediate calculations. Round your answer to $2$ decimal places.$)$

Standard deviation $?\%$

$2.$ What is the beta of your portfolio? $($Do not round your intermediate calculations. Round your answer to $2$ decimal places.$)$

Portfolio beta $?$

$3.$ What is the firm$-$specific variance of your portfolio? $($Do not round your intermediate calculations. Round your answer to $4$ decimal places.$)$

Firm$-$specific $?$

$4.$ What is the covariance between the portfolio and the market index? $($Do not round your intermediate calculations. Round your answer to $4$ decimal places.$)$

Covariance $?$
