Hello everyone.
00:01
So the question says that a pension fund manager is considering three mutual funds.
00:06
The first is a stock fund.
00:08
The second is a long -term government and corporate bond fund.
00:11
And the third is a t -bill money market fund that yields a rate of 4 .3%.
00:16
The probability distribution of the risk fund is as below.
00:22
That is stock fund for expected return is 13%.
00:26
So we'll write over here that it will be denoted by a e r s is equal to 13%.
00:37
Then bond fund that will be denoted by b, expected return that is e, rb is equals to 6%.
00:51
Then stock fund for stock fund standard deviation.
00:56
So standard deviation for stock fund is given 34%.
01:01
And similarly standard deviation for bond fund is given 27%.
01:11
The correlation between the funds funds returns is 0 .12%.
01:22
So cov for b as well as s is equals to correlation multiplied by standard deviation for stock fund multiplied by standard deviation for bond fund.
01:44
So putting the values we get 0 .12 multiplied by 335 .3 .3 .5 .5 .3 .5 .5 .3 .5 .5 .3 .5 .5...
