Step 1

For the Calculation of Alpha, first we have to calculate Beta of each stocks and Beta can be calculated by using this formula:

Expected Return of Stock = Risk-Free Rate (RF) + Beta (β) × (Market Return - Risk-Free Rate (RF))

Calculation of Beta (β) of Aggressive Stock: help_outlineImage Transcriptionclose4%=RF+Bx (7%+RF) = RF +7%xB+ BXRF (Equation 1) 38% RF+Bx (25%+ RF) = RF +25% x B+BXRF (Equation 2) From Subtracting Equation from Equation 2, we get 34%=18%xB 34% 18% 1.89 =B fullscreen
Step 2

Calculation of Beta (β) of Defensive Stock: help_outlineImage Transcriptionclose= RF 2.5%=RF Bx ( 7% + RF) 7%xB+ BXRF (Equation 1) (Equation 2) 16%=RF +Bx (25% + RF) = RF+ 25% x B+Bx RF From Subtracting Equation from Equation 2, we get 13.5%=18%xB 13.5% 18% 0.75 B fullscreen
Step 3

Beta of Aggressive Stock (β) = 1.89

T-Bill Rate or Risk-Free Rate (RF) = 3%

Market Return (MR) = (7% + 25%) ÷ 2 = 16%
