Agency Problems VERY Important
  • Conflict between different stakeholders
  • Bankruptcy stockholders/workers/bondholders
  • Typically management and shareholders for
    healthy firms.
  • Are these problems new?
  • Why firms often offer CEOs options?

  • Money Market
  • Bonds
  • Equities (Primary emphasis of this course)
  • Preferred Stock
  • Common Stock
  • Derivatives
  • Options
  • Futures
  • Swaps

Returns Across Asset Classes
100 Invested in 1926 in Different Assets
Risk and Return Across Assets
If these terms are not familiar to you, I suggest
you learn about mean, variance (standard
deviation), covariance correlation coefficient
Risk and Return Across Assets
Small Stocks
Large Stocks
Corp Bonds
Govt Bonds
Has this changed since March, 2000? Has this
changed since September, 2001?
Money Market Securities - Treasury Bills
  • Tax Considerations
  • Auction Process
  • Treasury Initial Maturities of 91 and 182 days

Competitive vs. Non-competitive
Money Market Securities - Treasury Bills
  • Bankers Discount Yield
  • Bond Equivalent Yield (APR)
  • Effective Annual Yield (EAY)
  • EAY ?? BEY ?? BDY

Treasury Notes and Bonds
  • Different maturities, Semi-annual coupons,
  • Coupon and Principal Strips
  • Quotations (32nds of Par, Bond Equivalent Yields)
  • N note // ci stripped of coupon // i indexed
    for inflation

Other Fixed-Income Securities
  • Corporate Bonds - Convertibility -- cv
    - Covenants - Secured versus unsecured
    debentures - Zero-coupon bonds -- zr
  • Extensive bond listings are no longer provided in

Example Municipal Bond After-tax Yield
  • Suppose short-term municipal yields are currently
    4, while comparable taxable bonds pay 5. Which
    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

Equity Capital Markets
  • Common Stocks
  • Ownership shares
  • Residual claims
  • Limited liability
  • Different with every paper etc. I use yahoo

Other Equity Securities
  • Preferred Stock
  • Cumulative Dividend
  • Special Tax treatment corporations 70
  • Dont really worry too much about for this class
  • May use if you start a business for certain
    ownership rights
  • Buffet used in mid 90s with USAIR

Stock and Bond Market Indices
  • Price-weighted Index (DJIA, Nikkei 225)
  • Value-weighted Index (SP 500)
  • Others Equally-weighted, geometrically-weighted,
    Bond market indices
  • Can we replicate returns on an index?

Example Index Calculations
  • What are the returns on a price-weighted, a
    value-weighted, and an equally-weighted index of
    stocks A, B, C.
  • What if stock split occurs? must tell you when

Derivative Securities Markets
  • Options Contracts
  • A Call (Put) option gives the holder the right to
    purchase (sell) an asset for a specified price on
    or before a specified date
  • Futures/Forwards Contracts
  • dont worry about too much for this class may
    talk about at end of class
  • A Futures contract obligates the holder to
    deliver an asset at a specified date for an
    agreed upon price to be paid at maturity
  • Hybrid Contracts
  • Index Options, Swaps


Chapter 3
  • Markets and Trading Processes
  • The Primary Market
  • The Secondary Market
  • NYSE, AMEX, Regional, NASDAQ, Foreign
  • Trading Arrangements
  • Types of orders, execution of trades, margin
    trading and short sales

The Primary Market
  • New issues of stocks, bonds and other securities
    are marketed to the public by investment banks in
    the Primary Market.
  • Initial Public Offering (IPO)
  • Seasoned Offering
  • Private Placement
  • Shelf-Registration

  • Public issues of securities are marketed to the
    public through underwriters.
  • The Underwriting Process
  • Select Underwriter
  • Form Syndicate
  • Registration Statement (Red Herring, Prospectus)
  • Set Offer Price
  • Stabilization (up to 10 days after offer date)
  • Other Considerations
  • Firm Commitment vs. Best Efforts
  • Negotiated vs. Competitive bidding
  • Cost is substantial
  • Underwriter compensation
  • Gross Spread (7.3 for IPOs, 5.4 for Seasoned
    equity issues, and 1.6 for bonds)
  • Underpricing (12-18, 7, 2)
  • Direct expenses (3.7, 1.7, and 0.6)
  • Pecking order theory
  • Have there been many IPOs lately?

The Secondary Market
  • Definitions
  • Agent versus Dealer markets
  • Continuous versus Call (auction) markets
  • The Third and Fourth markets
  • ECNs
  • Organized Exchanges vs. Over-the-Counter
  • Centralized location
  • Listing requirements
  • Market makers
  • Specialists

Trading 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 ?

NYSE Listing Requirements
  • Listed firms must also meet continued listing
  • Current NYSE Listing requirements
  • Dont worry about exact numbers There are
    exceptions that make the rules not worth

NYSE-Listed Firms
  • At the end of 2002 there were fewer companies
  • 448 foreign companies had securities listed on
    the NYSE

The NYSE Specialist
  • Functions
  • Provide Price Continuity and Stabilization
  • Process Information
  • Supply Immediacy (trader of last resort)
  • Agent and Dealer Roles
  • Obligations To provide a fair and orderly
  • Rights Exclusive market maker and Access to the
    limit order book
  • Trading Restrictions
  • Trades behind public orders

Specialist Profits
  • Commissions
  • on agency trades only (not dealer trades)
  • commissions are a small part of specialist
  • 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

The 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

NASDAQ 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
  • reveal the size of best customer limit orders

NASDAQ Listing Requirements
Types of Orders
  • Market Order
  • Limit Order
  • Stop-loss (Stop-buy) Order
  • Buying on Margin
  • Short Sale

Order 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

The 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?

Margin 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.

Margin 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
  • Magnification factor is 1/.5536.36/20
  • Bad is just opposite sign

Margin 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

  • 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

Short-Sale Example
  • You are bearish on ATT. The current market price
    is 50 per share and you anticipate selling short
  • How much cash and securities must you put into
    your brokerage account if the initial margin is
  • 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

Circuit Breakers
  • Trading Halts
  • NYSE
  • Started after 1987 market crash
  • Reviewed after 1997 market volatility
  • End of 2001 gt 180 point move no index arbitrage
  • program trading
  • 10 - Halt of 1 hour before 2pm
  • 20 - Halt of 2 hours before 1pm
  • 30 - Halt for day

Chapter 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

Services 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

Types 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

Closed End Funds
  • Number of Shares is Fixed
  • Traded on Secondary Markets -- Just like other
  • 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

Open 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

Mutual 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)

Professional 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

Why 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

Other Things to Consider
  • Bad performance persists more than good
  • 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

  • Generally available at any library
  • Most annual reports and prospectus available on
  • Morningstar -- Mutual Fund Source Book
  • http//
  • Mutual Fund Education Center
  • http//
  • Brills Mutual Fund
  • http//

  • 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????

Chapter 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
  • Bottom-up Start with companies then try and
    understand how state of world might affect them

Global Economic Considerations
  • Performance in countries and regions is highly
  • 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

Key Economic Variables
  • Gross domestic product
  • Unemployment rates
  • Think obvious and also impacts consumer sentiment
  • What were people talking about two or three years
  • 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?

Federal 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?

Federal 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

Demand 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

Business 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
  • 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

NBER 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

Industry 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
  • Financial leverage
  • What happened to the airlines after September 11,
  • Industry life cycles

Industry Life Cycles
  • Stage Sales Growth
  • Start-up Rapid Increasing
  • Consolidation Stable
  • Maturity Slowing
  • Relative Decline Minimal or Negative

Industry/Firm Life Cycle
Rapid and Increasing Growth
Stable Growth
Slowing Growth
Minimal or Negative Growth
Start Up
Relative Decline
Industry/Firm Life Cycle
  • Start Up - New technology, high risk, high
  • 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.

Chapter 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

Intrinsic 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

Dividend Discount ModelsGeneral Model
  • V0 Value of Stock
  • Dt Dividend
  • k required return

No 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

Constant 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

Estimating 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)

Partitioning Value Growth and No Growth
  • PVGO Present Value of Growth Opportunities
  • E1 Earnings Per Share for period 1

Partitioning 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
Price 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

P/E Ratio No Expected Growth
  • E1 - expected earnings for next year
  • E1 is equal to D1 under no growth
  • k - required rate of return

P/E Ratio with Constant Growth
  • b retention ratio
  • ROE Return on Equity

Numerical 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

Numerical 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

P/E Analysis
  • Pitfalls
  • Use of accounting earnings
  • Historical costs
  • May not reflect economic earnings
  • Reported earnings fluctuate around the business
  • 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.

Inflation 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

Chapter 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

Firm 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
  • 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.

Financial 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

Ratio Analysis
  • Purpose of Ratio Analysis
  • Uses
  • Trend analysis
  • Comparative analysis
  • Combination
  • Use by External Analysts
  • Important information for investment community
  • Important for credit markets

Type of Financial Ratios
  • Liquidity Ratios
  • Activity or Mgmt Efficiency Ratios
  • Leverage Ratios
  • Profitability Ratios
  • Market Price Ratios

Comparability 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

P/B Analysis - ROE decomposition
  • Are all ROEs created equal?
  • Two Breakdowns
  • DuPont
  • ROE NI / Equity
  • ROE NI/EBTEBT/EBITEBIT/SalesSales/AssetsAsse
  • Which tend to matter most?

interest burden
operating margin
asset turnover
tax burden
leverage (1D/E)
P/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

Examples with PEG P/E ratiosReturns are from
Oct 01 to Oct 02
Examples with PEG P/E ratiosReturns are from
Oct 02 to Oct 03
  • Bottom line, its tough to tell (not withstanding

  • 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
  • Important for Risk Premiums

Probability 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
  • Stocks can only decrease by 100 but can go up by
    more hence equity returns are skewed right.

Extending 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

The Minimum-Variance Frontierof Risky Assets
Extending 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

1. 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

Assumptions - Can these be relaxed???
  • Trades of individual investors do not affect
  • 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

  • All investors choose to hold the market portfolio
  • Know it is not true many investors try and time
  • 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

Investors 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
  • M Market portfolio

MMarket SP500? Wilshire 5000? World Equity
Passive 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
Equilibrium 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?

Expected 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, GM1.250.0810
  • What about portfolio of 50 Ford and 50 GM?
  • Could multiply out or just half way between 9.4

Security Market Line
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
CAPM 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?

Example Numbers
Picture of Example
2. 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?

Security Characteristic Line
R-squared measures proportion of total variation
in securitys return explained by its
relationship to the market portfolio, or how
well SCL describes XYscatterplot of points

  • (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
  • Model 2 is used by many especially when the risk
    free is so low

Using 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
  • But Black, Jensen, Scholes (1972) and Fama and
    MacBeth (1972) find alpha gt 0.
  • Implication ??

Is Beta/CAPM Dead? Chapter 8 preview
  • With Sharpes 1964 development, the popularity of
    CAPM took off because of simplicity and powerful
  • 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

CAPM 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?
  • 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

Average Monthly Returns vs. Beta (1963 - 1990)
The Grundy and Malkiel Study (Dont worry about
  • 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

Grundy Malkiel Mean Decile Returns,
24-Month-Preceding Betas
  • 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)

Arbitrage Pricing Theory Introduction Chapter
7 Continued
  • CAPM is derived from the Theory of Choice
  • requires behavioral assumptions
  • one factor explains cross-sectional expected
  • 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

Arbitrage 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.

Factor 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

Factor 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?

Individual 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
