DeterminantsofBetas&RelativeRisk
88
Beta of Equity (Levered Beta)
Beta of Firm (Unlevered Beta)
Nature of product or
service offered by
company:
Other things remaining equal,
the more discretionary the
product or service, the higher
the beta.
Operating Leverage (Fixed
Costs as percent of total
costs):
Other things remaining equal
the greater the proportion of
the costs that are fixed, the
higher the beta of the
company.
Implications
1. Cyclical companies should
have higher betas than noncyclical companies.
2. Luxury goods firms should
have higher betas than basic
goods.
3. High priced goods/service
firms should have higher betas
than low prices goods/services
firms.
4. Growth firms should have
higher betas.
Implications
1. Firms with high infrastructure
needs and rigid cost structures
should have higher betas than
firms with flexible cost structures.
2. Smaller firms should have higher
betas than larger firms.
3. Young firms should have higher
betas than more mature firms.
Aswath Damodaran
Financial Leverage:
Other things remaining equal, the
greater the proportion of capital that
a firm raises from debt,the higher its
equity beta will be
Implciations
Highly levered firms should have highe betas
than firms with less debt.
Equity Beta (Levered beta) =
Unlev Beta (1 + (1- t) (Debt/Equity Ratio))
88
Inaperfectworld…wewouldestimatethebetaofa
firmbydoingthefollowing
89
Start with the beta of the business that the firm is in
Adjust the business beta for the operating leverage of the firm to arrive at the
unlevered beta for the firm.
Use the financial leverage of the firm to estimate the equity beta for the firm
Levered Beta = Unlevered Beta ( 1 + (1- tax rate) (Debt/Equity))

Bottom-upBetas
92
Step 1: Find the business or businesses that your firm operates in.
Possible Refinements
Step 2: Find publicly traded firms in each of these businesses and
obtain their regression betas. Compute the simple average across
these regression betas to arrive at an average beta for these publicly
traded firms. Unlever this average beta using the average debt to
equity ratio across the publicly traded firms in the sample.
Unlevered beta for business = Average beta across publicly traded
firms/ (1 + (1- t) (Average D/E ratio across firms))
Step 3: Estimate how much value your firm derives from each of
the different businesses it is in.
Step 4: Compute a weighted average of the unlevered betas of the
different businesses (from step 2) using the weights from step 3.
Bottom-up Unlevered beta for your firm = Weighted average of the
unlevered betas of the individual business
Step 5: Compute a levered beta (equity beta) for your firm, using
the market debt to equity ratio for your firm.
Levered bottom-up beta = Unlevered beta (1+ (1-t) (Debt/Equity))
Aswath Damodaran
If you can, adjust this beta for differences
between your firm and the comparable
firms on operating leverage and product
characteristics.
While revenues or operating income
are often used as weights, it is better
to try to estimate the value of each
business.
If you expect the business mix of your
firm to change over time, you can
change the weights on a year-to-year
basis.
If you expect your debt to equity ratio to
change over time, the levered beta will
change over time.
