What is an advantage and disadvantage of the Capital Asset Pricing Model

$($CAPM$)?$ List one advantage and one disadvantage

One advantage of CAPM is how easy it is to calculate it$.$ Users of CAPM only need

to put in different variables to easily estimate the required rate of return for an

asset. However, one disadvantage of CAPM is the assumption that investors can

borrow and lend at a risk$-$free rate, and that is unattainable in the real world.
