The investor is expected to select the project that is less risky. In this case the project with the lowest standard deviation will be selected. Therefore, compute the standard deviation of each project.
State of the economy | Probability of occurrence of state of economy | Profit of project A if state of economy occurs | Probability*Profit | (Profit - Expected profit)^2 |
BOOM | 0.2 | 600 | 120 | 10000 |
NORMAL | 0.6 | 500 | 300 | 0 |
RECESSION | 0.2 | 400 | 80 | 10000 |
SUM | 500 | 20000 | ||
The expected profit for project A is 500. | ||||
The variance for project A is (Profit - Expected profit)^2 | ||||
The variance for project A is 20000. | ||||
Standard deviation = (20000)^(.5) | ||||
Standard deviation = 141.42. | ||||
The standard deviation for project A is equal to 141.42. | ||||
State of the economy | Probability of occurrence of state of economy | Profit of project B if state of economy occurs | Probability*Profit | (Profit - Expected profit)^2 |
BOOM | 0.2 | 1000 | 200 | 250000 |
NORMAL | 0.6 | 500 | 300 | 0 |
RECESSION | 0.2 | 0 | 0 | 250000 |
SUM | 500 | 500000 | ||
The expected profit for project B is 500. | ||||
The variance for project B is (Profit - Expected profit)^2 | ||||
The variance for project B is 500000. | ||||
Standard deviation = (500000)^(.5) | ||||
Standard deviation = 707.11 | ||||
The standard deviation for project B is equal to 707.11. | ||||
Project A is less risky because the standard deviation for project A is less than the standard deviation of project B. |
