So, the minimum variance for portfolio b is w as standard deviation, e minus e, s, d, multiplied with deviation s, multiplied with deviation d, the whole thing divided by deviation s squared plus deviation d squared minus 3 multiplied with d, s, d, multiplied with deviation s and deviation d.
01:09
So, for ws, ws is equal to d, 1 minus w.
01:18
So, calculating ws, we get 15 percent minus 0 .1 multiplied with 15 percent, multiplied with 15 percent, the whole thing divided by 20 percent, 15 percent, s squared minus 2 multiplied with 0 .1, 3 percent, multiplied with 15 percent.
02:21
So, final value is 90 .73, which is 0 .5.
02:44
And for wb, 1 minus 0 .5 is 0 .5.
02:54
So, calculate portfolio expected return, s standard deviation, expected return, and standard deviation b.
03:11
We get, multiplied with 20 percent, plus 0 .5 multiplied with 12 percent, which is 16 percent.
03:43
And, deviation b, we get, square root 0 .5 squared, multiplied with 30 percent, squared, plus 0 .5 squared, multiplied with 50 percent, squared, plus 2, multiplied with 0 .5, multiplied with 0 .1, multiplied with 30 percent, multiplied with 15 percent.
04:30
Here, we get the value, 90 .73 percent.
04:36
This is for the question number 4.
04:40
And for question number 5, we need to create a table for this one.
04:59
So, it is ws, er, b, percentage, and deviation b, percentage.
05:55
So, we need to create a table for this one.
05:58
So, we need to create a table for this one.
05:59
So, we need to create a table for this one.
05:59
So, we need to create a table for this one.
06:55
So, we need to create a table for this one.
06:59
So, we need to create a table for this one.
07:10
So, we need to create a table for this one.
07:27
So, we need to create a table for this one.
07:37
So, we need to create a table for this one...
