Ask you to calculate the beta of the portfolio.
00:05
So to calculate this question, first of all, you want to calculate the weight of each investment.
00:13
So the weight of a is the security amount invested, which is 2 ,000, divided by the total.
00:28
Total is going to be the auto money together.
00:30
2 ,000 plus 4 ,000, plus 6 ,000 plus 8 ,000.
00:44
And so from there you can see that this is 2 ,000 divided by 20 ,000.
00:53
So the weight is 0 .1.
00:56
Using the same method, we can calculate the weight of b.
01:02
And this equals the amount invested, which is 4 ,000, divide by the total, 20 ,000...
