Measuring Market Risk

Market Portfolio - Portfolio of all assets in the economy. In practice a broad stock market index is used to represent the market.

Beta - Sensitivity of a stock’s return to the return on the market portfolio.

12- 4

Measuring Market Risk

Example - Turbo Charged Seafood has the following % returns on its stock, relative to the listed changes in the % return on the market portfolio. The beta of Turbo Charged Seafood can be derived from this information.

Measuring Market Risk

B = = 0.81.62

When the market was up 1%, Turbo average % change was +0.8% When the market was down 1%, Turbo average % change was -0.8% The average change of 1.6 % (-0.8 to 0.8) divided by the 2% (-1.0 to 1.0) change in the market produces a beta of 0.8.

Portfolio Betas

Diversification decreases variability from unique risk, but not from market risk.

The beta of your portfolio will be an average of the betas of the securities in the portfolio.

If you owned all of the S&P Composite Index stocks, you would have an average beta of 1.0

Measuring Market Risk

CAPM - Theory of the relationship between risk and return which states that the expected risk premium on any security equals its beta times the market risk premium.

Market risk premium = r - r

Risk premium on any asset = r - r

Expected Return = r + B(r - r )

Capital Budgeting & Project Risk

The project cost of capital depends on the use to which the capital is being put. Therefore, it depends on the risk of the project and not the risk of the company.

12- 21

Example - Based on the CAPM, ABC Company has a cost of capital of 17%. [4 + 1.3(10)]. A breakdown of the company’s investment projects is listed below. When evaluating a new dog food production investment, which cost of capital should be used?

1/3 Nuclear Parts Mfr. B=2.0

1/3 Computer Hard Drive Mfr. B=1.3

1/3 Dog Food Production B=0.6

AVG. B of assets = 1.3

Capital Budgeting & Project Risk

12- 22

Example - Based on the CAPM, ABC Company has a cost of capital of 17%. (4 + 1.3(10)). A breakdown of the company’s investment projects is listed below. When evaluating a new dog food production investment, which cost of capital should be used?

R = 4 + 0.6 (14 - 4 ) = 10%

10% reflects the opportunity cost of capital on an investment given the unique risk of the project.
