Question

Problem 8-12
Required rate of return

1. Suppose rRF = 6%, rM = 13%, and bi = 2.1.

What is ri, the required rate of return on Stock i? Round your answer to two decimal places.
%

2. Now suppose rRF increases to 7%. The slope of the SML remains constant. How would this affect rM and ri? CHOOSE ONE.

Both rM and ri will remain the same.

Both rM and ri will increase by 1%.

rM will remain the same and ri will increase by 1%.

rM will increase by 1% and ri will remain the same.

Both rM and ri will decrease by 1%.

3. Now suppose rRF decreases to 5%. The slope of the SML remains constant. How would this affect rM and ri? CHOOSE ONE.

Both rM and ri will decrease by 1%.

rM will decrease by 1% and ri will remain the same.

rM will remain the same and ri will decrease by 1%.

Both rM and ri will increase by 1%.

Both rM and ri will remain the same.

4. Now assume that rRF remains at 6% but rM increases to 14%. The slope of the SML does not remain constant. How would these changes affect ri? Round your answer to two decimal places.

The new ri will be

5. Now assume that rRF remains at 6% but rM falls to 12%. The slope of the SML does not remain constant. How would these changes affect ri? Round your answer to two decimal places.

The new ri will be

Explanation / Answer

1. Suppose rRF = 6%, rM = 13%, and bi = 2.1.

What is ri, the required rate of return on Stock i? Round your answer to two decimal places.

As per CAPM

ri = rRF +(rM - rRF)*bi

ri = 6% + (13%-6%)*2.1

ri = 20.70%

2. Now suppose rRF increases to 7%. The slope of the SML remains constant. How would this affect rM and ri? CHOOSE ONE.

Both rM and ri will increase by 1%.

3. Now suppose rRF decreases to 5%. The slope of the SML remains constant. How would this affect rM and ri? CHOOSE ONE.

Both rM and ri will decrease by 1%.

4. Now assume that rRF remains at 6% but rM increases to 14%. The slope of the SML does not remain constant. How would these changes affect ri? Round your answer to two decimal places.

The new ri will be

ri = rRF +(rM - rRF)*bi

ri = 6% + (14%-6%)*2.1

ri = 22.80%

5. Now assume that rRF remains at 6% but rM falls to 12%. The slope of the SML does not remain constant. How would these changes affect ri? Round your answer to two decimal places.

The new ri will be

ri = rRF +(rM - rRF)*bi

ri = 6% + (12%-6%)*2.1

ri = 18.60%
