Macroeconomic Multifactor Models:                                             READING 27: RETURN CONCEPTS
      They use factors associated with economic variables
      that can be reasonably believed to affect cash flows                               MODULE 27.1: RETURN CONCEPTS
      and/or appropriate discount rates.


      The Burmeister, Roll, and Ross model incorporates the following five factors:

       confidence risk      = 2.0%    Unexpected change in the difference between the return of risky corporate bonds and government bonds.

       time horizon risk    = 3.0%    Unexpected change in the difference between the return of long-term government bonds and Treasury bills.
       inflation risk       = 4.0%    Unexpected change in the inflation rate.

       business cycle risk  = 1.6%
                                      Unexpected change in the level of real business activity.
       market timing risk   = 3.4%
                                      The equity market return that is not explained by the other four factors.
        As with the other models, to compute the required return, factor values are multiplied by a sensitivity coefficient (i.e., beta) for that stock; the products are summed and
        added to the risk-free rate.

                                                       Build-Up Method
                                                       required return = RF + equity risk premium + size premium + specific-company premium
                                                       (size of premium would be scaled up or down based on the size of the company).

                            Suppose that we are also   An example is the bond-yield plus risk premium method
                            given the following
                            sensitivities for stock j:   EXAMPLE: Company LMN has bonds with 15 years to maturity. They have a coupon of 8.2% and a price
                            0.3, –0.2, 1.1, 0.3, 0.5,   equal to 101.70. An analyst estimates that the additional risk assumed from holding the firm’s equity
                            respectively. Using the risk-  justifies a risk premium of 3.8%. Given the coupon and maturity, the YTM is 8%. Calculate the cost of
                            free rate of 3.4%, calculate   equity using the bond-yield plus risk premium approach.
                            the required return using a
                            multifactor approach.       Answer: cost of equity = 8% + 3.8% = 11.8%
        required return =                               Don’t loose sight what the components of each method convey: If asked in the
        3.4% + (0.3 × 2%) + (–0.2 × 3%) + (1.1 × 4%) + (0.3 × 1.6%)   exam evaluate style and/or the overall impact of a component on return,
        + (0.5 × 3.4%) = 9.98%
                                                        separate out each factor and its beta—paying careful attention to whether there
                                                        is a + or - sign attached to the component—and work through it logically.
