The proportion of the optimal risky portfolio that should be invested in stock A is 0%.

Using this formula

Stock A optimal risky portfolio=[(Wa-RFR )×SDB²]-[(Wb-RFR)×SDA×SDB×CC] ÷ [(Wa-RFR )×SDB²+(Wb-RFR)SDA²]- [(Wa-RFR +Wb-RFR )×SDA×SDB×CC]

Where:

Stock A Expected Return  (Wa) =16%

Stock A Standard Deviation (SDA)= 18.0%

Stock B Expected Return  (Wb)= 12%

Stock B Standard Deviation(SDB) = 3%  

Correlation Coefficient for Stock A and B (CC) = 0.50  

Risk Free rate of return(RFR) = 10%

Let plug in the formula

Stock A optimal risky portfolio=[(.16-.10)×.03²]-[(.12-.10)×.18×.03×0.50]÷ [(.16-.10 )×.03²+(.12-.10)×.18²]- [(.16-.10 +.12-.10 )×.18×.03×0.50]

Stock A optimal risky portfolio=(0.000054-0.000054)÷(0.000702-0.000216)

Stock A optimal risky portfolio=0÷0.000486×100%

Stock A optimal risky portfolio=0%

Inconclusion the proportion of the optimal risky portfolio that should be invested in stock A is 0%.

coldgirl [10]

Answer:

a. estimate the amount to mitigate high impact and probable issues.

Explanation:

In project management, a contractor can be defined as an individual or organization that temporarily undertakes a project in order to create a unique result, product, and service.

A contingency is an amount of money which is added to the initial or standard cost estimate so as to cover risk exposure and any uncertainty.

When making contingency estimates, the contractor should estimate the amount to mitigate high impact and probable issues.

As a result of uncertainties that are peculiar to everything in life, most especially projects undertaken, it is very important and necessary that the contractor should set aside an amount of money to mitigate or lessen any high impact such as dwindling prices, miscellaneous, faults, repairs and other probable issues that may arise in the process of execution.
