You are holding a stock that has a beta of 2.0 and is currently in equilibrium. The required return on the stock is 15%, and the return on an average stock is 10%. What would be the percentage change in the return on the stock, if the return on an average stock increased by 30% while the risk-free rate remained unchanged?

Answer:

The percentage change in the return on the stock is 40%

Explanation:

Beta = 2

Required return = 15%

Return on average stock = 10%

Step 1:

Calculating the risk free rate on return, we use the formula;

Required Rate of Return = Rf +Beta (Rm - Rf)

Where;

Rf = risk free rate

Rm = return on average stock =10%

Beta = 2

Substituting, we have

15% = Rf + 2 (10% - Rf)

0.15 = Rf + 2(0.1 - Rf)

0.15 = Rf +0.2- 2Rf

0.15 = 0.2 - Rf

Rf = 0.2-0.15

    = 0.05

Rf = 5%

Step 2: Calculating new market return, we have

Since the return on average stock  increased by 30%,

Therefore Rm = 1.3(10%) = 13%.

the  new required return on stock  becomes,

ks = 5% + 2(13% - 5%)  

    = 5% + 2*8%

   = 5% + 16%

   = 21%.

Step 3: percentage change in the return on the stock;

The percentage change  on return stock =  (21 - 15)/15

                                                                     = 6, 6/15

                                                                       = 40%

The percentage change in the return on the stock will be 40% if the return on an average stock increased by 30%  

Given Information

Beta = 2.0

Required return = 15%

Return on average stock = 10%

  • We are now calculating the risk free rate on return and the formula of the Required Rate of Return is Rf +Beta (Rm - Rf)

15% = Rf + 2 (10% - Rf)

0.15 = Rf + 2(0.1 - Rf)

0.15 = Rf + 0.2- 2Rf

0.15 = 0.2 - Rf

Rf = 0.2-0.15

Rf = 0.05

Rf = 5%

Now, we are calculating the new market return.

Given Information

The return on average stock increased by 30%,

Rm = 1.3*(10%)

Rm = 13%.

The new required return on stock is now as follows:

Ks= Rf +Beta (Rm - Rf)

Ks = 5% + 2*(13% - 5%)

Ks = 5% + 2*8%

Ks = 5% + 16%

Ks = 21%.

Percentage change on return stock =  (21 - 15)/15

Percentage change on return stock = 6/15

Percentage change on return stock = 0.40

Percentage change on return stock = 40%

Therefore, the percentage change in the return on the stock will be 40% if the return on an average stock increased by 30%
