3. Correlation coefficient

4. Portfolio variance In terms of the correlation coefficient

5. Diversification, minimum variance  E(R)  A B MV

6. The case of r = 1

7. Portfolio expected return

8. Still  = 1

9. Expected return

10. Substitute out X B

11. Diversification, minimum variance  E(R)  A B MV

12. Now r = -1

14. Diversification with a risk-free asset  E(R) A= risk-free asset B MV

15. Capital Market Line Expected return of portfolio Standard deviation of portfolio’s return. Risk-free rate (R f ) M... Capital market line. X Y.. Indifference curve preferred

16. Argument for the security market line  Only beta matters  A mix of T-Bills and the market can produce any beta.  An asset with that beta is no better or worse than the two-fund counterpart  Hence it has the same return.

17. Security Market Line Expected return on security (%) Beta of security RmRm RfRf 1 M. 0.8 S. T. Security market line (SML) S is overvalued. Its price falls T is undervalued. Its price rises...
