Using Yahoo! Finance find the value of beta for your reference company. Write a two page paper discussing the following items:

- What is the estimated beta coefficient of your company? What does this beta mean in terms of your choice to include this company in your overall portfolio?
- Given the beta of your company, the present yield to maturity on U.S. government bonds maturing in one year (currently about 4.5% annually) and an assessment that the market risk premium (that is – the difference between the expected rate of return on the ‘market portfolio’ and the risk-free rate of interest) is 6.5%, use the CAPM equation in order to find out what is the present ‘cost of equity’ of your company? Explain what is the meaning of the ‘cost of equity’?
- Choose two other companies, look up their “Beta” and report the names of these companies and their betas. Suppose you invest one third of your money in each of the stocks of these companies. What will the beta of the portfolio be? Given the data in (b), what will the Expected Rate of Return on this portfolio be? Do you feel that the three-stock portfolio is sufficiently diversified or does it still have risk that can be diversified away? Explain.
