You have performed the James optimization on a portfolio with 3 assets whose risk/return characteristics are summarized in the table below:

Asset 1

Asset 2

Asset 3

E[r]

5.00%

10.00%

15.00%

s.d.

10.00%

15.00%

20.00%

The ‘bordered matrix’ for the optimal risky portfolio based on these three assets is given below:
