Investment and Equity Cost
2. Suppose the market portfolio has an expected return of 10% and a volatility of 20%, while Microsoft’s stock has a volatility of 30%.
- A. Given its higher volatility, should we expect Microsoft to have an equity cost of capital that is higher than 10%?
No, Microsoft is diversifiable and it will not be affected by the changes in the market. We do not expect Microsoft’s equity cost of capital to be higher than 10%. Each stock carries its own weight.
- B.What would have to be true for Microsoft’s equity cost of capital to be equal to 10%?
In order for Microsoft’s equity cost of capital to be 10% its beta will have to be 1. 4. Suppose all possible investment opportunities in the world are limited to the five stocks listed in the table below.
- What does the market portfolio consist of (what are the portfolio weights)?
Stock Price/Share ($) Number of Shares Outstanding (millions) A 10 10 B 20 12 C 8 3 D 50 1 E 45 20
- Total value of the market = 10×10+20×12+8×3+50×1+45×20= $1. 314 billion
- Stock Portfolio Weight A 10×10=100 100/1314 =0. 0761 x 100 = 7. 61%
- B 20×12= 240 240/1314 =0. 1826 x 100= 18. 6%
- C 8×3= 24 24/1314= 0. 0183 x 100 = 1. 83%
- D 50x 1 = 50 50/1314=0. 03381 x 100 = 3. 81%
- E 45×20 = 900 900/1314= 0. 6859 x 100 = 68. 49%
- Total = 100% 5.
Using the data in Problem 4, suppose you are holding a market portfolio, and have invested $12,000 in Stock C.
A. How much have you invested in Stock A? 12,000x(10×10)/(8×3)=$50,000
