Estimating betas
3 approaches to estimate beta
1. Using historical data on market prices
2. From fundamentals
3. Using accounting data

How to calculateBottom up
Beta
1.1. Find the median historical (regression) beta and the median D/E ratio for a
sample of comparable companies. Use the Damodaran link here:
http://pages.stern.nyu.edu/~adamodar/New_Home_Page/datafile/Betas.html
1.2. Calculate the median unlevered beta for the sample (cell G7 in bottom-up
beta file):
π½π =π½πΏ
(1 + 1 β π‘π·πΈ
)
2. Find the companyβs marginal tax rate and D/E ratio and use the formula for
levered beta to find the levered beta of the company where the unlevered beta is
the one from step 1.1. above:
π½πΏ = π½π 1 + 1 β π‘π·
πΈ

Bottom-up fundamental beta
Bottom-up beta is more precise than the historical beta because:
- averages across companies
- reflects current business mix
For AbbVie:
historical (regression) beta was 0.8827
bottom-up beta is 1.8631
Conclusion: using historical beta would severely understate the riskiness of the stock!

Estimating the risk premium (π π β π πΉ)
β’ Risk Premium - return demanded by investors for moving money from a riskless investment to a risky investment
β’ Depends on:
1. Risk aversion of investors
2. Riskiness of the investment

Historical Risk Premia
β’ Most common approach in CAPM: difference b/n avgreturns on stocks and avg returns on risk-free securities over an extended period of time
Process:
Step 1: Define time period (up to 1871 in U.S.*)
Step 2: Calculate avg. returns for a stock index over time
Step 3: Calculate avg. returns for a riskless security over time
Step 4: Historical RP = step 2 result β step 3 result

Historical Risk Premia
Causes of differences in practical estimation:
1. time period used: long is better
- Risk aversion is likely to change over time so using short period β estimation error
2. choice of risk-free security: long-term govβt bonds
3. method for calculating avg. returns: arithmetic vs. geometric
- Arithmetic average: sum/N
- Geometric average: compounded return= (π£πππ’π ππ ππππππ π)
