Betas, Capital Budgeting and Risk: Chapter 9
(Note: We will not be covering section 94)
Topics:
WACC
Asset β
When you can (can’t) use the WACC as a discount rate in capital budgeting.
A firm’s value can be stated as the sum of the value of the assets; PV of cash flows that
accrue (sooner or later) to bondholders and stockholders. I.e.:
Firm value = PV of cash flows assets produce for security holders (debt, PS, CS)
Example of projects of differing risk:

What would happen if we used the WACC to evaluate ALL projects (both high and
low risk)?
Company Cost of Capital (COC) is based on the
average
beta of the assets (or their
assets AVERAGE market risk). The average beta of the assets is based on the
% of
Market Value of each
asset
Example
1/3 New Ventures β =2.0
1/3 Expand existing business β =1.3
1/3 Plant efficiency β =0.6
AVG β of assets = 1.3

Compute the proportion of Dell’s variance due to market risk if the total variance of
Dell Computer Company (annualized) is 720.
Compute the proportion of Dell’s variance due to business risk.
Can we reject the hypothesis that Dell’s stock has less market risk than average?

Compute the Standard Error of the BETA for GM.
Can we reasonably reject the
hypothesis that GM’s beta is negative?
Compute Campbell Soup’s beta using the most recent 5 years of monthly data.
Compute the amount of variance due to market risk and the amount of variance due
to business risk. Is “0” within a 95% confidence interval of Campbell Soup’s beta?
Compute Campbell Soup’s beta and a 95% confidence interval for the beta the most
recent 1year of daily data.

What we really want is the beta in the future period
for
which we are trying to predict returns.
Can we estimate the future expected beta using past
data
?
Evidence of
Beta
Stability: Chart in text: percentage of stocks in same risk category 5years later.
Notes:

We want beta check stability over time for the same firm

Estimate beta for a portfolio of all stock in the same industry (industry beta)
What to do if equity beta is not
stable. (How would we know this? When would this
be an issue for a firm manager?):
The Weighted Average Cost of Capital:

not Book Value for D and E

is the rate of return on new issues of debt (equity)
Query: The WACC measures required rate for projects of:
a)
All risks
b)
Average risk This is what the WACC and RRR is reflecting
c)
Some risk (not riskless)
What is the difference between the required rate of return on debt and equity, and
the firm’s cost of debt and equity?
