QUESTION 4
You are given the following data about expected returns on a security on the LUSE where different states of the economy have the same probability of occurrence:
State Return
Strong growth 9.0%
Normal growth 6.5%
Weak growth 2.5%
Recession -4.5%
Required:
Compute and fully interpret the following for the investment:
[3 Marks]
[6 Marks]
[4 Marks]
[7 Marks]
Total 20 Marks
a)
State | Return | Probability | Expected Return |
Strong growth | 9% | 25% | 2.25% |
Normal growth | 7% | 25% | 1.63% |
Weak growth | 2.50% | 25% | 0.63% |
Recession | -4.50% | 25% | -1.13% |
Total | 3.38% |
Hence total expected return is 3.38%.
b) Downside deviation is a measure of downside risk that focuses on returns that fall below a minimum threshold or target return.
Using average return as target return 3.38% from question a)
Volatility of security return using downside deviation:
State | Return (a) | Probability (b) | Expected Return (c) | Return(a) -target(3.38) (d) | (Return -target)^2 |
Strong growth | 9% | 25% | 2.25% | 0.000% | 0.000% |
Normal growth | 7% | 25% | 1.63% | 0.000% | 0.000% |
Weak growth | 2.50% | 25% | 0.63% | -0.875% | 0.008% |
Recession | -4.50% | 25% | -1.13% | -7.875% | 0.620% |
Total | 3.38% | -8.750% | 0.628% | ||
Target Return | 3.38% | ||||
Downside Deviation | Sqrt (0.628/4) = 3.96% |
You can see in column (d) for strong and normal growth it is 0 as we are using downside deviation hence -ve difference should be used.
Hence volatility is 3.96% using downside deviation.
c)
