Investment |
Beta |
A |
$1,951 |
0.7 |
B |
$2,625 |
0.3 |
What is the beta for this mutual fund (i.e. what is the portfolio beta)?
Portfolio beta is weighted average of the beta of contituents.
Portfolio beta = w1 * Beta1 + w2 * Beta2
w1 = $1951/($1951 + $2625) = 0.4264
w2 = $2625/($1951 + $2625) = 0.5736
Portfolio beta = (0.4264 * 0.7) + (0.5736 * 0.3) = 0.30+0.17 = 0.47
