Consider the following situation:
| 
 State of Economy  | 
 Probability of State of Economy  | 
 Returns if State Occurs  | 
||
| 
 Stock A  | 
 Stock B  | 
 Stock C  | 
||
| 
 Boom  | 
 20%  | 
 25%  | 
 10%  | 
 5%  | 
| 
 Recession  | 
 80%  | 
 -30%  | 
 5%  | 
 10%  | 
The expected return on the market portfolio is 7% and the US Treasury bill yields 3%. The capital market is currently in equilibrium.
| a) Systematic Risk = Beta | |||||||
| Returns if State Occurs | Expected Return | ||||||
| State of Economy | Probability of State of Economy | Stock A | Stock B | Stock C | Prob. x Stock A 's Return | Prob. x Stock A 's Return | Prob. x Stock A 's Return | 
| Boom | 20.00% | 25.00% | 10.00% | 5.00% | 5.00% | 2.00% | 1.00% | 
| Recession | 80.00% | -30.00% | 5.00% | 10.00% | -24.00% | 4.00% | 8.00% | 
| Total | -19.00% | 6.00% | 9.00% | ||||
| According CAPM Expected Return E(R)= Risk free Rate + Beta x (Market Return - Risk free Rate) | |||||||
| Risk Free Rate RF = | 3.00% | ||||||
| Return on market RM | 7.00% | ||||||
| Stock A 's Beta = -19% - 3% = Beta x (7% -3%) | -5.5 | ||||||
| Stock B 's Beta = 6% - 3% = Beta x (7% -3%) | 0.75 | ||||||
| Stock C 's Beta = 9% - 3% = Beta x (7% -3%) | 1.5 | ||||||
| Stock C has the most systematic risk because it has the highest beta. | |||||||
| b) | |||||||
| Stock A has the most unsystematic risk because it has the negative Beta. |
