These are efficient portfolios, denoted with A, B, and C. 30 Figure 7.16 Lending and Borrowing • Lending or borrowing at the risk-free rate (rf) allows us to exist outside the efficient frontier. 31 The Efficient Portfolio with Borrowing and Lending 22 The Market Risk is Measured by Beta • Market Portfolio: Portfolio of all assets in the economy. In practice, a broad stock market index such as the S&P Composite is used to represent the market. • The risk that a stock contributes to a well-diversified portfolio is its market risk. • Market risk is the risk that a stock shares with the market. • Beta: Sensitivity of a stock’s return to the return on the market portfolio, defined as: π½π = πππ 2 ππ (1) πππ is the covariance between the returns on stock i and the returns on the market. 2 ππ is the variance of the returns on the market. Total risk = (Market risk) + (Specific risk) => ππ = πππ ππ + (1 − πππ )ππ ππππππ‘ πππ π = πππ ππ = πππ π ππππ π = πππ ππ = πππ 2 ππ ππ = π½π ππ ==> π΄πππππ ππππ = π·π ππ΄ (2) where: π½π = 23 πππ 2 ππ (1) Figure 8.1 The Return on Amazon Stock • The return on Amazon stock changes on average by 1.55% for each 1.00% change in the market return.

The market risk of a stock is measured by its beta. 2. The risk of a well-diversified portfolio is given by its market risk. • We also know the beta of a portfolio is the weighted average of the betas of the individual stock in the portfolio. • Beta measures undiversifiable risk. So, there is no diversification effect when adding a stock to a well-diversified portfolio. • If a portfolio includes a large number of randomly selected stocks, its beta is 1.0 • Adding low-beta stocks to a portfolio lowers the overall risk, but this is NOT “Diversification” it is “de-risking” • Investing higher proportion of your wealth in Treasury bills is another way of de-risking. 28 The relationship between Risk and Return – CAPM We know that the market risk of a stock is measured by its beta. • How much extra return an investor expects for bearing market risk? From Chapter 7: Capital Market Line: ππ = ππ + ππ −ππ ππ ππ (3) This equation gives the expected return for an efficient portfolio that combines borrowing or lending and the market portfolio. • An investor is rewarded only for market risk (π½π ,eq.2) (we replace ππ with π½π ): ππ = ππ + ππ − ππ ππ − ππ ππππππ‘ πππ π ππ π π‘πππ π = ππ + (π½π ππ ) = ππ + π½π (ππ − ππ )=> ππ ππ ππ = ππ + π·π (ππ΄ − ππ ) (4) or: ππ = ππ + π·π (ππ΄ − ππ ) The risk premium of a stock depends only on its beta: π½π = (5) CAPM πππ 2 ππ 29 Risk and Return - Capital Market Line The risk in the horizontal line is measured by the standard deviation. 04/09/2023 30 Figure 8.3 Capital Asset Pricing Model The risk in the horizontal axis is measured by the beta (π½) Security Market Line (πππΏ) πΈππ’ππ‘πππ: π¬ π = πΉπ + π· ∗ (πΉπ − πΉπ ) 31 Figure 8.4 Equilibrium What if a stock did not Lie on the security Market Line? • In equilibrium, no stock lies below the security market line. • Instead of buying Stock A, investors lend part of their money and put the balance in the market portfolio. • Instead of buying Stock B, they borrow and invest in the market portfolio. 32 Capital Market Line and Security Market Line • The Capital Market Line (CML) applies only to efficient portfolios. • Individual stocks and inefficient portfolios carry more risk and lie below the CML. • Investors still hold them as part of a diversified portfolio, but they get rewarded only for systematic risk. • The Security Market Line (SML) applies to all stocks, securities and portfolios. The expected returns in the vertical axis are drawn against… …the total risk ππ in the horizontal axis (CML), …the market risk π½π on the horizontal axis (SML). • An investor may hold inefficient assets as part of their portfolio because the inefficiencies (specific risk) are wash away. • Specific (idiosyncratic) risk is not compensated. • An efficient portfolio is comprised of individual inefficient securities. 33 The Capital Market Line and the Security Market Line 34 Does CAPM Hold in the Real World? • The CAPM makes several assumptions: 1. Investors choose portfolios based on expected return and risk (variance of returns). 2. All investors have the same estimates of mean returns, variances, and covariances. 3. Investors trade in perfect capital markets. • no Taxes. • no Transaction Costs. • no restrictions on Short Sales. 4. Investors can borrow and Lend at the same risk-free rate. 5. Investors are price takers. 6. The supply of all assets is fixed. Pros: • Asset classes with more risk command a higher expected return • The expected returns should not depend on diversifiable risk (only on market risk - beta) • Most financial managers use it (73% in a survey by Graham, Harvey 2001) • Questions: Unrealistic assumptions – empirical evidence. 35 Figure 8.5 CAPM (1931–2020) • Beta Versus Average Risk Premium. 36 Figure 8.6 Relationship Between Beta and Average Return (mid-19 60s) 37 Figure 8.6 Relationship Between Beta and Average Return (19 66–2020) • Source: F.

Which portfolios are efficient. ATP: Assumes that each stocks risk premium depends on pervasive macroeconomic “factors”. πΉπππππ = πΆ + ππ πππππππ π + ππ πππππππ π + ππ πππππππ π + β― + πππππ (6) ππππ π stands for specific, diversifiable risk. The expected risk premium on a stock depends on the expected risk premium associated with each ‘factor’ and the sensitivity of the stock returns to each factor: π¬πππππππ πΉπππ π·ππππππ = π − ππ = ππ πππππππ π − ππ + ππ πππππππ π − ππ + β― (7) 40 Three-Factor Model • Steps to Identify Factors: 1. Identify a reasonably short list of macroeconomic factors that could affect stock returns. 2. Estimate the expected risk premium on each of these factors: πππππππ π − ππ etc. 3. Measure the sensitivity of each stock to the factors (ππ , ππ , etc.) Factor Measured by Market factor Return on market index minus risk-free interest rate Size factor Return on small-firm stocks less return on large-firm stocks Book-to-market factor Return on high book-to-market-ratio stocks less return on low book-to-market-ratio stocks 41 Table 8.5 Estimates of Expected Equity Returns Using Three-Factor Model and CAPM Three- Factor Model Factor Sensitivities a CAPM B market B size B book-to-market Expected Return a Expected Return b Autos 1.12 0.26 0.31 11.9% 10.2% Banks 1.18 0.09 0.65 13.1 10.5 Chemicals 1.19 0.26 0.41 12.8 10.7 Computers 1.30 −0.18 0.03 10.5 10.9 Construction 0.96 0.49 0.04 10.4 9.3 Food 0.67 −0.38 0.02 5.6 6.3 Oil and gas 1.17 0.49 0.90 15.3 11.0 Pharmaceuticals 0.91 0.20 −0.38 7.5 8.5 Telecoms 0.78 −0.24 0.12 7.2 7.2 Utilities 0.46 −0.36 −0.08 3.7 4.8 The expected return equals the risk-free interest rate plus the factor sensitivities multiplied by the factor risk premiums, that is: 2.0 + πππππππ‘ ∗ 7.0 + ππ§ππ π ∗ 3.1 + πππππ−π‘π−ππππππ‘ ∗ 4.0 . b Estimated as ππ + π½ ππ − ππ , that is: ππ + π½ ∗ 7.0 Note that we use simple egression to estimate beta in the CAPM formula.

This is the correct discount rate only if the project beta is 0.75. 45 The Company Cost of Capital – Debt and Equity rassets ο½ Cost of Capital D E = rE ο΄ ο« rE ο΄ V V V ο½ Dο«E D ο½ market value of debt E ο½ market value of equity rD ο½ YTM on bonds rE ο½ rf ο« ο’ ο¨ rm ο rf ο© • Important: E, D, and V are all market values of equity, debt, and total firm value 46 Estimating Beta - Figure 9.2 U.S. Steel The SML shows the relationship between return and risk. CAPM uses beta as a proxy for risk.
