Use the information in table $1$ belowto answer questions $1\mathrm{.}1$ to $1\mathrm{.}2\mathrm{.}7.$ Note that the correlation matrix merely shows the correlations between the four assets in the table $($e$.$g$.$ correlation between asset A and asset C is $0\mathrm{.}60)$

$1\mathrm{.}1$ Explain $($and provide an illustration wit separate CALs for each portfolio$)$ which pf the four portfolios in table $1$ is $($are$)$ on the worst$-$possible CAL.

$1\mathrm{.}2$ Use the information in Table $1$ to calculate and explain the following:

$1\mathrm{.}2\mathrm{.}1$ Which portfolio have the largest correlation

$1\mathrm{.}2\mathrm{.}2$ Which two portfolios have the smallest correlation

$1\mathrm{.}2\mathrm{.}3$ Use the $$Markowitz formula$$ to calculate the historical standard deviation of portfolio consisting of $40\%$ in portfolio A and $60\%$ in portfolio D$.$ Call it portfolio AD
