TAILIEUCHUNG - Lecture Managerial finance - Chapter 7: Portfolio theory and other asset pricing models

Chapter 7 provides knowledge of portfolio theory and other asset pricing models. This chapter presents the following content: Portfolio theory, capital asset pricing model (CAPM)L: capital market line (CML), security market line (SML). | Chapter 7 Portfolio Theory and Other Asset Pricing Models Topics in Chapter Portfolio Theory Capital Asset Pricing Model (CAPM) Capital Market Line (CML) Security Market Line (SML) Expected Portfolio Return, rp Risk, p Efficient Set Feasible Set Feasible and Efficient Portfolios Feasible and Efficient Portfolios The feasible set of portfolios represents all portfolios that can be constructed from a given set of stocks. An efficient portfolio is one that offers: the most return for a given amount of risk, or the least risk for a give amount of return. The collection of efficient portfolios is called the efficient set or efficient frontier. IB2 IB1 IA2 IA1 Optimal Portfolio Investor A Optimal Portfolio Investor B Risk p Expected Return, rp Optimal Portfolios Indifference Curves Indifference curves reflect an investor’s attitude toward risk as reflected in his or her risk/return tradeoff function. They differ among investors because of differences in risk aversion. An investor’s optimal portfolio is defined by the tangency point between the efficient set and the investor’s indifference curve. What is the CAPM? The CAPM is an equilibrium model that specifies the relationship between risk and required rate of return for assets held in well-diversified portfolios. It is based on the premise that only one factor affects risk. What is that factor? What impact does rRF have on the efficient frontier? When a risk-free asset is added to the feasible set, investors can create portfolios that combine this asset with a portfolio of risky assets. The straight line connecting rRF with M, the tangency point between the line and the old efficient set, becomes the new efficient frontier. M Z . A rRF M Risk, p The Capital Market Line (CML): New Efficient Set . . B rM ^ Expected Return, rp Efficient Set with a Risk-Free Asset What is the Capital Market Line? The Capital Market Line (CML) is all linear combinations of the risk-free asset and Portfolio M. Portfolios below the CML are inferior. The CML defines the new efficient set. All investors will choose a portfolio on the CML. rp = rRF + Slope Intercept ^ p. rM - rRF ^ M Risk measure The CML Equation What does the CML tell us? The expected rate of return on any efficient portfolio is equal to the risk-free rate plus a risk premium. The optimal portfolio for any investor is the point of tangency between the CML and the investor’s indifference curves. rRF M Risk, p I1 I2 CML R = Optimal Portfolio . R . M rR rM R ^ ^ Expected Return, rp Capital Market Line What is the Security Market Line (SML)? The CML gives the risk/return relationship for efficient portfolios. The Security Market Line (SML), also part of the CAPM, gives the risk/return relationship for individual stocks. The SML Equation The measure of risk used in the SML is the beta coefficient of company i, bi. The SML equation: ri = rRF + (RPM) bi How are betas calculated? Run a regression line of past returns on Stock i versus returns on the market. The regression line is called the characteristic line. The slope coefficient of the characteristic line is defined as the beta coefficient. CAPM: ri = rRF + (rM - rRF)bi ri = + ()() = CAPM Required Return for Stock i
