Once again we can use the CAPM to estimate MMMs cost of equity. From the Internet, you can find a number of different sources for estimates of betaselect the measure that you think is best, and combine this with your estimates of the risk-free rate and the market risk premium to obtain an estimate of its cost of equity. (See the Taking a Closer Look problem in Chapter 8 for more details.) What is your estimate for MMMs cost of equity? Why might it not make much sense to use the DCF approach to estimate MMMs cost of equity?
