# Utility

Please see attached.

Base on the following info, and assume a concave utility function.

(ERA, ) = (10, 3), (ERB, ) = (10, 4), (ERC, ) = (11, 3) and (ERD, ) = (11, 4).

How can I establish a dominance relationship between the following securities based on

the expected return, standard deviation pairs (ER, )?

Are there any alternative method?
