  1. Managerial Finance FINA 6335 The CAPM and Cost of Capital Lecture 9

  2. Simplifying Assumptions • Individuals can trade securities without regard to fees, taxes, and other frictions. • Individuals get any relevant information about the firms they are interested in costlessly. • Individual investors can borrow or save at the same riskless rate equal the the “riskfree rate”

  3. Market Equilibrium All investors have the same CML because they all have the same optimal risky portfolio given the risk-free rate. CML return Optimal Risky Porfolio rf 

  4. Market Equilibrium The CML: Rp = Rf + (sp /sM)(RM- Rf ) CML return Optimal Risky Porfolio rf 

  5. Definition of Risk When Investors Hold the Market Portfolio • Researchers have shown that the best measure of the risk of a security in a large portfolio is the beta (b)of the security. • Beta measures the responsiveness of a security to movements in the market portfolio.

  6. Estimates of b for Selected Stocks

  7. The Formula for Beta

  8. Relationship between Risk and Expected Return (CAPM) • Expected Return on the Market: • Expected return on an individual security: Market Risk Premium This applies to individual securities held within well-diversified portfolios.

  9. Expected return on a security Risk-free rate Beta of the security Market risk premium = + × • Assume bi = 0, then the expected return is RF. • Assumebi = 1, then Expected Return on an Individual Security • This formula is called the Capital Asset Pricing Model (CAPM)

  10. Relationship Between Risk & Expected Return Expected return b 1.0

  11. Relationship Between Risk & Expected Return Expected return b 1.5

  12. Summary and Conclusions • This chapter sets forth the principles of modern portfolio theory. • The expected return and variance on a portfolio of two securities A and B are given by

  13. Summary and Conclusions • The efficient set of risky assets can be combined with riskless borrowing and lending. In this case, a rational investor will always choose to hold the portfolio of risky securities represented by the market portfolio. P

  14. Summary and Conclusions • The contribution of a security to the risk of a well-diversified portfolio is proportional to the covariance of the security's return with the market’s return. This contribution is called the beta. • The CAPM states that the expected return on a security is positively related to the security’s beta:

  15. Characteristic Line Slope = bi Estimating b with regression Security Returns Return on market % Ri = ai + biRm + ei

  16. Security Market Line Slope = R(m)-R(f) Security Market Line Security Returns Beta Ri = Rf + bi(Rm – Rf )

  17. Practical Issues in CAPM • Forecasting Beta • The problem is that you assume your estimate of Beta is the true value of Beta • “regression toward one” • Allow for extremes • What Time Horizon • 2 years of weekly, or 5 years of monthly

  18. The Security Market Line • Risk free interest rate? • The Market Risk Premium 5.7%

  19. Firm valuation • See Chapter 18, Section 1 and 2. • We will want to value the firm using the Discounted Cash Flow (DCF) method. • Three issues: • What do you want to discount? • How do you project this over time? • How do you discount it?

  20. Be Heroic!!!

  21. Basic Valuation • What do you want to Discount? • How do you project these? • How do you discount these?

  22. Basic Valuation • What do you want to Discount? • Free Cash Flow • How do you project these? • How do you discount these?

  23. Basic Valuation • What do you want to Discount? • Free Cash Flow • How do you project these? • From Historical Data • How do you discount these?

  24. Basic Valuation • What do you want to Discount? • Free Cash Flow • How do you project these? • From Historical Data • How do you discount these? • The Cost of Capital or (Weighted Average)

  25. Free Cash Flow • Start with EBIT • Subtract Taxes • Leaves EBIT(1-t) = Unlevered (Operating) Net Income • Plus Depreciation • Less Capital Expenditures • Less Increases in Working Capital • Bottom Line: = Free Cash Flow

  26. Example: Current Sales = $60 Cost of Goods Sold 25 Gross Profit 35 Less Operating Expenses 9 Less Depreciation 6 EBIT 20 Less Income Tax Rate (@ 35%) 7 Operating (Unlevered) NI 13 Plus Depreciation 6 Less Capital Expenditures 2 Less Increases in Working Capital 1 Free Cash Flow 16

  27. How do we make estimates? • 1. Income tax should be the statutory rate. • Depreciation: You need to project depreciation into the future. Will increase as Capital Expenditures increase. How do you estimate? • Capital Expenditures: Note, to propel growth, you need to invest: How do you determine Cap Ex =??? • Finally, Changes in Working Capital?

  28. Projections of Growth: • Recall: growth depends on 2 variables: Retention rate = (1 – Payout ratio) Return on Investments = Operating Income as a percentage of Book Value of Assets • Consider Historical Rates as well:

  29. Discount Rate • Conceptually: V = Present Value of the firm’s Cash flows, discounted by a number called the “cost of capital” Basically it is the IRR of the Firm. Conceptually, you want to discount by a rate that reflects the risk of the firm’s operating Cash Flow.

  30. How do you estimate this • Weighted Average Cost of Capital Once you have the stream of operating Cash Flows generated by the firm, the next problem is to determine how to discount it. The discount rate that makes the Value of the firm equal the firm’s cash flow is what we call the Cost of Capital. As a practical matter this can be approximated by the Weighted Average Cost of Capital (WACC)

  31. WACC • The WACC is defined as: rWACC = rE X (E/(E+D)) + rD(1-t) X (D/(E+D)) The weighted average of the (after tax) cost of the component securities issued by the firm, weighted by the proportion of those securities issued by the firm. rE is the required return to the equity of the firm rD is the required return to the debt of the firm D is the (market value) of the debt issued by the firm E is the market value of the equity. t is the firms tax rate.

  32. WACC Estimation • Some of these variables are not easily estimated so we make some assumptions: To estimate D use the Book value of the debt. To estimate rD use the ratio of Total Interest payments to the total book value of the debt To estimate rE use the Capital Asset Pricing Model
