gives you the higher after-tax yield if your tax
bracket is 0? 10? 20? 30? - At what tax rate would you be indifferent between
the two bonds? - 5(1-tax rate) 4 -- indifferent at tax rate

- Organized Exchanges vs. Over-the-Counter
- Centralized location
- Listing requirements
- Market makers

26Trading in the U.S.
- The NYSE, NASDAQ and AMEX are national in scope.
- Proportions traded by other regional exchanges
are small - NASDAQ double counts some trades so not exactly
like this but close - Below is percent of dollar volume
- (Different than share volume)
- Market Capitalization of NASDAQ is 2.8 Trillion
and NYSE is 16 Trillion (11.7 US) what does this
tell you ?
27NYSE Listing Requirements
- Listed firms must also meet continued listing
requirements - Current NYSE Listing requirements
- Dont worry about exact numbers There are
exceptions that make the rules not worth
knowing
28NYSE-Listed Firms
- At the end of 2002 there were fewer companies
- 448 foreign companies had securities listed on
the NYSE
29The NYSE Specialist
- Functions
- Provide Price Continuity and Stabilization

- Obligations To provide a fair and orderly
market - Rights Exclusive market maker and Access to the
limit order book - Trading Restrictions

30Specialist Profits
- Commissions
- on agency trades only (not dealer trades)
- commissions are a small part of specialist
revenues - Bid-Ask spread
- Returns on Inventory Positions
- Empirical Research
- Sofianos - spread revenues and position losses
- Hasbrouck/Sofianos and Madhavan/Smidt -
specialists appear to make short-term trading
profits
31The Over-the-Counter (OTC) Market
- Self regulated by the National Association of
Securities Dealers (NASD) - The NASD owns and operates its own automated
quotation system (NASDAQ) - Markets at the end of 2000 and 2001
- National Market System (What you think of as
NASDAQ.) 3827gt 3351 - Small Cap 907 gt 758
- Total Market Capitalization
- 3.6 Trillion to 2.8 trillion (then NASDAQ was at
1950)
32NASDAQ Characteristics
- A decentralized, electronically linked market
- Multiple market makers
- Different than the NYSE -- it is a decentralized
dealer market -- harder to control and regulate - Imperfect coordination between dealers
- 1996 try for more disclosure
- display all limit orders
- make public best quotes (dont pay for order
flow) - reveal the size of best customer limit orders
33NASDAQ Listing Requirements
34Types of Orders
- Market Order
- Limit Order
- Stop-loss (Stop-buy) Order
- Buying on Margin
- Short Sale
35Order Qualifications
- Day Orders
- Good-till-canceled Orders
- Fill or Kill (FOK) --immediate execution of whole
order -- no NASDAQ - Immediate or Cancel (IOC) -- immediate execution
but accept partial order - All or None (AON) -- most likely to use in real
world -- 200 shares or greater with limit - Market-on-Close/Open
36The Costs of Trading
- Commissions
- Brokers charge commissions in return for services
such as security analysis, investment advice,
deposit for securities, and access to trading. - Bid-Ask Spread
- What factors typically affect the spread?
- How do spreads compare across exchanges?
37Margin Trading
- Margin is the capital put up by investors when
using credit from their broker to buy securities. - Call loan rate
- Initial vs. Maintenance Margins
- Minimum initial margins are set by the Federal
Reserve, they are currently 50. - Equity is the Market Value of the Position less
the amount of the loan.
38Margin Trading Example
- Assume an initial margin requirement of 55 and
maintenance margin of 40. An investor has
5,500 in cash and wishes to purchase ABC stock.
ABC is currently trading at 100 per share. - Choices (1) buy 55 shares (2) buy 100 shares
on marginPrice is either good -- 120 or bad --
80 at the end - Ret (TV1-TV0)/(TV0-borrowed)
- Good -- just equity -- (6600-5500)/(5500-0)20
- Good -- margin -- (12000-10000)/(10000-4500)36.3
6 - Magnification factor is 1/.5536.36/20
- Bad is just opposite sign
39Margin Example Continued
- At what price will you receive a Margin Call from
your broker?Mm(sharesP-borrowed
money)/sharesP0.4(100P-4500)/100P gtgt P75 - How does this example change if your broker
charges a call loan rate of 10? - Just subtract interest payment (will assume 1
year here) - (12000-10000-4500.1)/550029.82
40Short-Sales
- Short sales allow investors to profit from a
decline in security price by selling a security
borrowed from another investor. - SEC Rules
- short sales must be identified to the exchange
- margin accounts are marked-to-market each day
- subject to the Tick Test Rule
41Short-Sale Example
- You are bearish on ATT. The current market price
is 50 per share and you anticipate selling short
100 shares. - How much cash and securities must you put into
your brokerage account if the initial margin is
50? - 50 100 shares 50/share 2500
- How high can the price go before you get a margin
call if the maintenance margin is 30? - .3 (7500-100P)/100P 57.7
42Circuit Breakers
- Trading Halts
- NASDAQ?
- NYSE
- Started after 1987 market crash
- Reviewed after 1997 market volatility

43Chapter 4 -- Mutual Funds
- Investment Companies (financial intermediaries)
- Collect Funds from individuals
- Defined contribution vs. Defined Benefit
- Invest in wide range of securities
- Corporate Bonds Bond Quality
- Money Market
- Real Estate Commercial, Resid -- Mixed
- Equities, Index, special sector, value
- Yahoo Mutual Fund Center
44Services of Investment Companies
- Administration and Record Keeping
- Diversification and Divisibility
- Professional Management
- Reduced Transaction Costs
- Usually small (250 to 3000 dollar minimum
investment -- less for retirement accounts) - Most of you will have a choice of mutual funds to
invest in for your retirement account - It will probably be or was the first investment
for many of you
45Types of Investment Companies
- Unmanaged -- Unit Investment Trusts
- Managed -- Closed End Funds
- Can sell at a discount or premium
- Managed -- Open End Funds
- Always sell at NAV
- NAV Cash and Securities minus Liabilities Total
Number of Shares
46Closed End Funds
- Number of Shares is Fixed
- Traded on Secondary Markets -- Just like other
equities - Prices can and do differ from NAV
- If traded at premium -- usually do to hard to
invest countries (Middle East, Africa, Asia) - Most traded at a discount
- Why might an investor choose closed end over open
end?
47Open Ended Funds
- Shares issued and redeemed directly from
investment Company - Shares are bought and sold at NAV but may have
sales commission - Values Change Daily
- Number of Shares Change Daily
- ETFs are like mutual funds but they trade during
the day
48Mutual Fund Fees (Open-End)
- Front-End -- Less than 8.5
- Back-End -- Start at 5 to 6 and can decrease
over time - Operating Fees are deducted from assets
- Operating Fees
- Usually shown as of Assets each year
- 12b-1 fees
- SEC rule that allows funds to charge investors
for distribution costs (Advertising, Annual
Report, Commissions)
49Professional Management
- Most professionally managed mutual funds do worse
than the index they represent by the amount of
transaction costs - Professionally managed funds tend to outperform
indices for foreign mutual funds Why? - Most investment companies charge less than 2 per
year -- however 2 per year for many years can be
very substantial - Assume 12 return
- Assume 30 years till retirement
- Value of 1 dollar at 10 annual return is 17.45
- Value of 1 dollar at 12 annual return is 29.96
50Why Invest?
- Primarily -- low transaction costs
- Can Choose passive index mutual funds that charge
0.3 - 0.5 management fee - Think segment will do better over a period of
time -- but not sure which company - Efficient markets and most finance professors
believe this is dangerous and should not bet on
one sector over another - energy
- health care
- technology
51Other Things to Consider
- Bad performance persists more than good
performance - Be careful of front end loads
- Tax Efficiency of Mutual Funds
- if in a retirement account -- Dont care
- if in a taxable -- you care -- prefer they do not
turn over a portfolio much -- you have to pay
taxes!!!!!
52Information
- Generally available at any library
- Most annual reports and prospectus available on
line - Morningstar -- Mutual Fund Source Book

- Brills Mutual Fund
- http//www.brill.com/
53Constraints
- Liquidity -- How soon you might need the money --
generally, the more liquidity you need, the less
risk you can take - Financial assets tend to be much more liquid than
real assets - Longer the horizon, the greater the risk you may
be able to take - Unique Needs
- if you worked for Boeing, would you want your
retirement fund or your other investments in
aerospace defense stocks? - Tax Deferred Retirement Plan
- IRA
- 401(k)
- Roth IRA
- Very confusing????
54Chapter 11 Framework of Analysis
- Fundamental Analysis
- Approach to Fundamental Analysis
- Domestic and global economic analysis
- Has changed significantly 70s, 80s, 90s today
- Industry analysis
- Hard to compare across different industries
- Grocery stores Vs Aerospace
- Company analysis
- Top-down Vs Bottom-up approach
- (personal bias for Top-down)
- Top-Down Start with world and work down to
companies - Bottom-up Start with companies then try and
understand how state of world might affect them
55Global Economic Considerations
- Performance in countries and regions is highly
variable - Political risk
- Middle east
- Emerging markets in Asia
- Maybe not followed that closely in the 1990s or
at least thought of as a local problem as
opposed to global - Exchange rate risk
- Sales
- Profits
- Stock returns
56Key Economic Variables
- Gross domestic product
- Unemployment rates
- Think obvious and also impacts consumer sentiment
- What were people talking about two or three years
ago - Interest rates inflation
- Ability to borrow and general risk to economy
- International measures/exchange rates
- Can be important even if small amount of sales
overseas-- Boeing - Consumer sentiment
- Watched much more closely than it used to be
- Current recession vs. past recessions?
57Federal Government Policy
- Fiscal Policy - government spending and taxing
actions -- Mostly impact demand - Direct policy
- Slowly implemented
- Argument that by the time the impact is felt it
is already too late????? - Can stimulate or slow the economy
- What are Bush and the Congress trying to do now
-- how?
58Federal Government Policy
- Monetary Policy - manipulation of the money
supply to influence economic activity -- 14 year
terms (Board) - Initial feedback effects
- Tools of monetary policy
- Open market operations
- Buy put money into economy sell take out
- Discount rate
- Reduce discount rate makes it easier
(theoretically) for companies to borrow - True today?
- Reserve requirements
- May change to improve liquidity but can be
dangerous
59Demand and Supply Shocks
- Demand shock - an event that affects demand for
goods and services in the economy - Tax rate cut
- Increases in government spending
- Supply shock - an event that influences
production capacity or production costs - Commodity price changes
- oil or electricity in the last year
- Educational level of economic participants
- Could argue corporate tax cuts
60Business Cycles
- Business Cycle
- Peak -- Entering recession. Defensive industries
that are not sensitive to economic conditions
should do well (food producers, tobacco
companies, public utilities, pharmaceutical
companies). - Trough -- Economic recovery begins. Cyclical
industries that are sensitive to the economy
should do well (autos, washing machines, etc). - Industry relationship to business cycles
- Cyclical - Cars
- Defensive Sin/Consumer Staples
61NBER Cyclical Indicators
- Leading Indicators - tend to rise and fall in
advance of the economy Yahoo Link - Examples
- Stock Prices
- Housing???
- Machine Orders????
- Coincident Indicators - indicators that tend to
change directly with the economy - Examples
- Industrial production
- Manufacturing and trade sales
- Lagging Indicators - indicators that tend to
follow the lag economic performance - Examples
- Ratio of consumer installment credit outstanding
to personal income - Inventories
- Credit Outstanding to Personal Income
62Industry Analysis
- Sensitivity to business cycles
- Factors affecting sensitivity of earnings to
business cycles - Sensitivity of sales of the firms product to the
business cycles - Operating leverage

65Industry/Firm Life Cycle
- Start Up - New technology, high risk, high
growth. - Consolidation - Survivors are more stable, market
share is more predictable, still grow faster than
the overall economy. - Maturity - Product reaches full potential, growth
tracks growth in economy, price competition.Cash
Cows - stable cash flows but little opportunity
for expansion. - Decline - Slow or no growth, competition or
obsolete product.
66Chapter 12 Fundamental Stock Analysis Models
of Equity Valuation
- Basic Types of Models
- Balance Sheet Models
- Dividend Discount Models
- Price/Earning Ratios
- Estimating Growth Rates and Opportunities
67Intrinsic Value and Market Price
- Intrinsic Value (IV) True Value?
- Self assigned Value
- Variety of models are used for estimation
- Market Price
- Consensus value of all potential traders
- Trading Signal
- IV gt MP Buy
- IV lt MP Sell or Short Sell
- IV MP Hold or Fairly Priced
68Dividend Discount ModelsGeneral Model
- V0 Value of Stock
- Dt Dividend
- k required return
69No Growth Model Example
No Growth Model
Stocks that have earnings and dividends that are
expected to remain constant Preferred Stock
- E1 D1 5.00
- k .15
- V0 5.00 / .15 33.33
70Constant Growth Model g constant
perpetual growth rate Example
- E1 5.00 b 40 k 15
- (1-b) 60 D1 3.00 g 8
- V0 3.00 / (.15 - .08) 42.86
71Estimating Dividend Growth Rates
- g growth rate in dividends
- ROE Return on Equity for the firm
- b plowback or retention percentage rate
- (1- dividend payout percentage rate)
72Partitioning Value Growth and No Growth
Components
- PVGO Present Value of Growth Opportunities
- E1 Earnings Per Share for period 1
73Partitioning Value Example
- ROE 20 d 60 b 40
- E1 5.00 D1 3.00 k 15
- g .20 x .40 .08 or 8
Vo value with growth NGVo no growth component
value PVGO Present Value of Growth Opportunities
74Price Earnings Ratios
- P/E Ratios are a function of two factors
- Required Rates of Return (k)
- Expected growth in Dividends
- Uses
- Relative valuation
- Extensive Use in industry
75P/E Ratio No Expected Growth
- E1 - expected earnings for next year
- E1 is equal to D1 under no growth
- k - required rate of return
76P/E Ratio with Constant Growth
- b retention ratio
- ROE Return on Equity
77Numerical Example No Growth
- E0 2.50 g 0 k 12.5
- P0 D/k 2.50/.125 20.00
- P/E 1/k 1/.125 8
78Numerical Example with Growth
- b 60 ROE 15 (1-b) 40
- E1 2.50 (1 (.6)(.15)) 2.73
- D1 2.73 (1-.6) 1.09
- k 12.5 g 9
- P0 1.09/(.125-.09) 31.14
- P/E 31.14/2.73 11.4
- P/E (1 - .60) / (.125 - .09) 11.4
79P/E Analysis
- Pitfalls
- Use of accounting earnings
- Historical costs
- May not reflect economic earnings
- Reported earnings fluctuate around the business
cycle - Things to think about
- We can also obtain a price estimate by
multiplying projected earnings by a forecast of
the price/earnings multiple (P/E). - Consider two firms from a previous exampleThe
firm with good growth opportunities (and b.6)
was worth P200, or P/E 200/5 40.The firm
with no growth opportunities was worth P50, or
P/E 50/5 10. - The Result P/E multiples can be good indicators
of growth opportunities.
80Inflation and Equity Valuation
- Inflation has an impact on equity valuations
- Historical costs underestimate economic costs
- Empirical research shows that inflation has an
adverse effect on equity values - Research shows that real rates of return are
lower with high rates of inflation - Shocks cause expectation of lower earnings by
market participants - Returns are viewed as being riskier with higher
rates of inflation - Real dividends are lower because of taxes
81Chapter 13 Firm-Specific analysis -
- How do we choose stock within an industry?
- Equity Value Definitions
- Book Value - The net worth of the firm as shown
on the balance sheet - Liquidation Value - The value of the firm if
broken up and sold off (after paying off all
obligations). This may provide a floor for the
stock price. - Replacement Cost - Cost to replace all assets
less the value of liabilities.Tobins Q
Market Price / Replacement Cost
82Firm Specific Analysis
- In order to determine the value of a company, we
must move away from the balance sheet and
actually forecast cash flows. - Once we have cash flow forecasts, we can use
models such as the Dividend Discount Model or
Price to Earnings multiples to estimate firm
value. - Comparing our estimate of value to the current
market price tells us whether we should invest in
the security.Market Value - The price at which
a security is currently trading.Intrinsic Value
- The firm or the present value of expected
future cash flows. This represents the value of
the firm as an ongoing concern.
83Financial Statements
- Balance Sheet Income Statement
- Common Sized -- vertical analysis
- Trend or Indexed -- horizontal analysis
- Common sized simply puts everything in a
percentage and allows comparison from year to
year -- all expenses add up to 100 - Trend Looks at percentage increase and decrease
from year to year hard to compare with other firms
84Ratio Analysis
- Purpose of Ratio Analysis
- Uses
- Trend analysis
- Comparative analysis
- Combination
- Use by External Analysts
- Important information for investment community
- Important for credit markets
85Type of Financial Ratios
- Liquidity Ratios
- Activity or Mgmt Efficiency Ratios
- Leverage Ratios
- Profitability Ratios
- Market Price Ratios
86Comparability Problems
- Accounting Differences
- Inventory Valuation
- Depreciation
- Inflation
- International Accounting Conventions
- After we go through the theory models we will go
back to securities analysis and work on some
regressions.
87P/B Analysis - ROE decomposition
- Are all ROEs created equal?
- Two Breakdowns
- DuPont
- ROE NI / Equity
- ROE NI/EBTEBT/EBITEBIT/SalesSales/AssetsAsse
ts/Equity - Which tend to matter most?
interest burden
operating margin
asset turnover
tax burden
leverage (1D/E)
88P/E Analysis - PEG ratio
- A simple control is to divide P/E ratio by
earnings growth rate. - I took 1 year average forecast of earnings
- Yahoo uses five year forecast of earnings
- The Motley Fools say
- PEG 0-0.5 BUY PEG 0.5 - 0.65 WEAK BUY
- PEG 0.65 - 1.00 HOLD PEG gt 1.00 SELL
89Examples with PEG P/E ratiosReturns are from
Oct 01 to Oct 02
90Examples with PEG P/E ratiosReturns are from
Oct 02 to Oct 03
91Conclusions
- Bottom line, its tough to tell (not withstanding
my data problems) - did not control for earning growth beyond t1
- did not do relative valuation against other
sectors - perhaps whole sector is overvalued...
- Best when performed on a lot of firms over time
- hold other factors constant as well
- market capitalization
- institutional ownership
- average trading volume
- these may control for liquidity premiums
- other risk-premiums unique from beta
- we would like to find a big, liquid, value stock,
with high growth, high payout, and low risk ---
good luck
92Dow Dividend Strategies
- Dogs of the Dow
- Sort by d/P
- Invest in top 10 yielding stocks each year
- Rebalance annually
- Strategy from 1973 -1994 yielded 17.23 vs.
11.19 - Dow Five (OHiggins)
- Invest in lowest five priced stocks stocks each
year - Strategy from 1973-1994 yielded 21.1 vs 11.19
- Foolish Four (Motley Fools)
- Throw out the least expensive Dow component
- Invest 40 in 2, and 20 each in the remaining
three - Strategy yielded 25.2 vs. 11.19 from 1973 - 1994
93Investing
- Many people have more pain from loses than
happiness they get from gains - specify objectives
- identify constraints
- formulate policy
- monitor performance
- reevaluate and modify portfolio as determined
from monitoring - Check out your own funds
- Dont do anything until you know the tax
implications
94Chapter 5Interest Rates
- Supply
- Households
- Provide capital
- Most companies do not have large amounts of cash
like Microsoft - Demand
- Businesses
- Typically need investment established companies
used bonds - Governments Net Supply and/or Demand
- Federal Reserve Actions
- What is one of the things that is currently being
discussed by the Democratic candidates with
respect to supply and demand?
95Real vs. Nominal Rates
- Fisher effect Approximation
- nominal rate real rate inflation premium
- R r i or r R - i
- Example r 3, i 6
- R 9 3 6 or 3 9 - 6
- Fisher effect Exact
- r (R - i) / (1 i)
- 2.83 (9-6) / (1.06)
- Empirical Relationship
- Inflation and interest rates move closely
together - Important for Risk Premiums
96Probability Distributions
- 1) Mean most likely value µ or E(r)
- 2) Variance or standard deviation
- 1s 68.3 should be between µ /- s
- 2s 95.4
- 3s 99.7
- 3) Skewness
- If a distribution is approximately normal, the
distribution is described by characteristics 1
and 2 - We assume this at times such as portfolio theory
even though it is not true. Returns may be
normal for short time periods with a steady
drift. - Stocks can only decrease by 100 but can go up by
more hence equity returns are skewed right.
97Measuring Mean Scenario or Subjective Returns

scenarios. - Rule 2 The variance of an assets return is the
expected value of the squared deviations from the
expected return.

risk-free asset, the portfolio standard deviation
equals the risky assets standard deviation
multiplied by the portfolio proportion invested
in the risky asset. - Rule 5 When two risky assets with variances s12

132Extending Concepts to All Securities
- The optimal combinations result in lowest level
of risk for a given return - The optimal trade-off is described as the
efficient frontier - These portfolios are dominant
133The Minimum-Variance Frontierof Risky Assets
134Extending to Include Riskless Asset
- The optimal combination becomes linear
- A single combination of risky and riskless assets
will dominate - History
- Started with just returns and dominance
- Then one risky asset and one risk free asset
- SP 500 and Rf
- Then talked about two risk assets
- SP500 and Bonds
- Then two risky assets and risk free
- Now multiple risky assets and risk free
- Multiple assets ? get market portfolio will

1391. Capital Asset Pricing Model
- The CAPM is a centerpiece of modern finance that
gives predictions about the relationship between
risk expected return - Based on original work on portfolio theory of
Harry Markowitz by Nobel laureate William Sharpe
John Lintner in 1965 - chapters 6-8 - Begins with simplistic assumptions for
hypothetical world of investors and builds into
reasonable comprehensive model
140Assumptions - Can these be relaxed???
- Trades of individual investors do not affect
prices - Carl Icon
- Risk-averse utility-maximizing investors
- Some people live for risk
- One-period investment horizon (myopic)
- We are not!
- Fixed quantities of assets and all marketable
- IPOs
- No taxes, transactions costs, regulations, etc
- There are and you know my views
- Homogeneous Expectations - All investors analyze
securities in same way with same probabilistic
forecasts for each - We do not agree for every buyer there is a
seller
141Implications
- All investors choose to hold the market portfolio
- Know it is not true many investors try and time
markets - The market portfolio is on the efficient frontier
- Probably true but impossible to define
- The Capital Market Line is the best attainable
Capital Allocation Line - True for most of us
- The Risk Premium on individual assets will be
proportional to the risk premium on the market
and the beta of the security (with the market). -
Just like Chapter 8 - but with beta
142Investors hold Market Portfolio
- All investors will identify same optimal risky
portfolio, M to combine with riskless asset - For supply/demand to clear, the holdings of each
security will be by relative market value
outstanding - M Market portfolio
MMarket SP500? Wilshire 5000? World Equity
Index?
143Passive Indexing is Efficient
- Market portfolio must be on efficient frontier
and it is tangent point for the best feasible
capital allocation line - Mutual Fund Theorem Rational investors will
passively hold an equity index fund a money
market fund
Capital Market Line
M
144Equilibrium Expected Returns
- CAPM is built on insight that appropriate risk
premium on an asset is determined by contribution
to risk of investors overall portfolio, i.e.
portfolio risk is what matters - Market price of risk or
is the benchmark tradeoff for risk return,
because all investors holdings are on CML --
Sometimes you see it divided by variance as well
as standard deviation (Can use Standard Deviation
or Variance - How does any individual security contribute to
the risk (and return) of a well-diversified
portfolio like the market portfolio?
145Expected Return/Beta Relation
- The relevant measure of risk is a securitys
return covariance with that of market - Beta is the measure of covariance risk
- Suppose historical risk premium for SP 500 index
is 8 with std dev of 22. - What is risk premium of Ford stock with beta of
1.10? GM with beta of 1.25? - Ford 1.10.088.8, GM1.250.0810
- What about portfolio of 50 Ford and 50 GM?
- Could multiply out or just half way between 9.4
146Security Market Line
A
SML
M
If a security plots off the Security Market Line,
its expected return is different from its fair
return, or it is misplaced. May be true for
small periods of time
147CAPM Example
- Two professional money managers are being
evaluated. One averaged 19 last year and the
other managed only 16. However, the first
managers beta was 1.3 and the second manager had
a beta of 1.0. - Which manager performed better?
- If the market risk premium were 8 and Tbills
were yielding 6, which is better? - What if market risk premium is 12 and Tbills
yield 3?
148Example Numbers
149Picture of Example
1502. CAPM and the Market Model
- Alphas and betas are measured statistically using
historical returns on the security and the market
portfolio proxy, e.g. SP 500 - Simple regression model, known as Market Model,
is used (in excess returns) -
- Statistically, beta measures the sensitivity of
changes in securitys return to changes in market
portfolio proxys return - Sound like CAPM beta? What about alpha?

152The CAPM Beta
- How does any individual security contribute to
the risk of a well-diversified portfolio like
RM? - What is the Beta of the Market Portfolio?
- Note that if the SML holds for individual
securities it also holds for portfolios. What is
?P?
153Estimating Betas
- Alternatives 1 Excess, 2 total
- (1)
- (2)
- Alphas and betas are measured statistically using
historical returns on the security and the market
portfolio proxy, e.g. SP 500 - Statistically, beta measures the sensitivity of
changes in securitys return to changes in market
portfolio proxys return. - Model 1 is typically employed in tests of the
CAPM - Model 2 is used by many especially when the risk
free is so low

157Using the models
- Models employ ex-post returns
- CAPM is a statement about ex-ante returns
- If CAPM is true, the expected value of alpha0
from excess return model (1) - from market model regressions, we expect the
average alpha 0. - Most early studies show this to be true, Jensen
(1968) - But Black, Jensen, Scholes (1972) and Fama and
MacBeth (1972) find alpha gt 0. - Implication ??
158Is Beta/CAPM Dead? Chapter 8 preview
- With Sharpes 1964 development, the popularity of
CAPM took off because of simplicity and powerful
predictability - Many critiques challenged premise of systematic
risk as only factor that differentiates average
returns of assets - Roll Critique of 1979 and market proxy
- Fama and French in 1992 uncovered new evidence
about beta and book/market ratio
159CAPM and Beta
Common Sense Riskier assets must provide a
higher expected return ? CAPM attempt to
answer these questions! But How well does
the CAPM fulfill this task?
how should risk be measured?
which type of risk is priced in the market?
160- DEFINITION OF RISK
- Conventional ApproachRisk Chance that actual
investment outcomes differ from expected outcome - But Positive outcomes are not unfavorable!
- However, if outcomes are symmetric the Variance
should work as a measure of risk

162BETAS DEATH
163The Grundy and Malkiel Study (Dont worry about
name.)
- time frame 1968 -1992, declining market periods
with flexible duration - do a sort on market ?, form portfolio deciles
- regress the CAPM equation to determine portfolio
? - vary market proxies (SP 500 and Equal-weighted
market proxy) - vary lengths of time (preceding 24 and 60 month
periods - I just show the 24 month but same for
60 months) - find 4 decile ? and their returns during bear
markets
164Grundy Malkiel Mean Decile Returns,
24-Month-Preceding Betas
165Conclusions
- High-beta stocks suffer significantly greater
losses than low beta stocks in declining markets. - The above conclusion holds for each period and
does not change significantly when different
market proxies and lengths of time are used to
estimate beta. - Beta is a useful tool in forecasting short-term
risk in declining markets. - Value Line and Merrill Lynch Adjustment Equations
- High betas tend to over predict future betas
low betas tend to under predict - MLAdj. Beta 0.33753 0.66257(unadj. Beta)
- VL Adj. Beta 0.35 0.67(unadj. Beta)
- VL Betas are rounded to second decimal place of 0

166Arbitrage Pricing Theory Introduction Chapter
7 Continued
- CAPM is derived from the Theory of Choice
- requires behavioral assumptions
- one factor explains cross-sectional expected
returns - What is that factor???
- APT is derived from the Law of One Price
- requires less behavioral assumptions
- allows for several systematic factors
- Like multifactor CAPM
167Arbitrage Pricing Theory
- An arbitrage opportunity arises when an investor
can construct a zero-investment portfolio that
will yield sure profits in future - A zero-investment portfolio is one in which some
securities are long, others short with no
commitment of investors money - This fundamental concept lies at heart of an
alternative asset pricing model, known as the
APT, developed by Steve Ross in 1977.
168Factor Models
- All security returns are pervasively affected by
several macroeconomic factors -
- Different stocks have different sensitivities (b
coefficients) to different factors, e.g. banks
and inflation, auto companies and national income
growth, etc. - Factor models can quantify these multiple sources
of risk
169Factor Portfolios
- If we understood the attributes of factors, we
could construct portfolios of stocks for which
returns mimic factor movements - Consider well-diversified portfolios built to
have unique exposure to one factor and no
exposure to other factors. - Can we construct factor portfolios from these two
stocks A and B?
170Individual Assets and APT
- Each well-diversified factor portfolio is
available to any investor and each has an
expected excess return, - Consider an individual security, Z.
- Can we construct a SUPER portfolio combining
T-bills and factor portfolios to have same
expected returns and no security-specific risk?
What is that portfolio? What should be the
expected return on security
