Consider the following information about three stocks:

State of Economy Probability of State of Economy Rate of Return if State Occurs

Stock A Stock B Stock C

Boom $\mathrm{.}25\mathrm{.}25\mathrm{.}30\mathrm{.}56$

Normal $\mathrm{.}45\mathrm{.}22\mathrm{.}17\mathrm{.}14$

Bust $\mathrm{.}30\mathrm{.}00\mathrm{.}30\mathrm{.}46$
