Estimating Beta

Now that you have calculated the monthly returns, you can estimate the beta for Mylan using regression analysis. The data object rets you calculated previously is stored in memory.

When you regress the company return (ticker: MYL) on the market index return (ticker: SPY), beta is the resulting coefficient for the market index return in that regression. In this exercise, we want to perform a regression of myl on spy using the lm() function and then extract the beta from the regression summary.

Note: To extract beta, recall that it is the second element of the coefficient matrix (i.e., coeff[2]).

Many individuals and institutions invest in equities. To do so effectively, the investor must have a solid understanding of how the value of the equity compares to the stock price. In this course, we focus on fundamental concepts of equity valuation. We begin with a discussion of time value of money and then move on to the first of two discounted cash flow methods we will discuss - the free cash flow to equity valuation model.

Exercise 1: Course Intro and Fundamental Valuation Exercise 2: Time Value of Money Exercise 3: Difference Between Valuing Enterprise and Equity Cash Flows Exercise 4: The Free Cash Flow to Equity Model Exercise 5: Calculating Operating Profit Exercise 6: Calculate Free Cash Flow to Equity Exercise 7: Calculating Terminal Value Exercise 8: Calculating Equity Value Exercise 9: Calculating Present Value of Free Cash Flow to Equity Exercise 10: Calculate Present Value of Terminal Value Exercise 11: Calculate Equity Value

One of the critical components of free cash flow to equity valuation is using reliable projections. In the first part of this chapter, we will discuss ways to analyze the projections to help us identify the right questions to ask. In the second part of this chapter, we will go through the second of our discounted cash flow models - the dividend discount model. In this approach, we discount expected dividends instead of free cash flows.

Exercise 1: Analyzing the Projections Exercise 2: Analyze Revenue Trends - Bar Chart Exercise 3: Analyze Revenue Trends - Regression Exercise 4: Perpetuity Growth Rate Exercise 5: Calculate Retention Ratio Exercise 6: Perpetuity Growth Rate Calculation Exercise 7: Dividend Discount Model Exercise 8: Valuing Preferred Stock Exercise 9: Valuation Assuming No Dividends For First Few Years Exercise 10: Valuation Assuming 2-Stages of Dividends

To be able to discount cash flows, we need a discount rate. For the free cash flow to equity and dividend discount model, the cost of equity is the appropriate discount rate. In this chapter, we will discuss how each of the components of the cost of equity are calculated.

Relative valuation allows us to use the valuation of comparable companies to infer the value of our subject firm. In this chapter, we discuss how to identify comparable companies and how to calculate valuation multiples. We also show how to analyze the determinants of multiples.

This chapter combines the lessons from Chapters 1 to 4 in a series of exercises. You will be asked to inspect the data and to value the firm using discounted cash flow and relative valuation approaches. At the end, you will combine the results in a summary table.
