Suppose your expectations regarding the stock price are as follows:

State of the Market	Probability				Ending Price				HPR (including dividends)
Boom		0.28			$	140				53.5	%
Normal growth		0.23				110				20.0
Recession		0.49				80				17.0

Use the equations E(r)=sp(s)r(s)E(r)=sp(s)r(s) and 2=sp(s)[r(s)E(r)]22=sp(s)[r(s)E(r)]2 to compute the mean and standard deviation of the HPR on

MEAN: ? %

Standard Deviation: ? %
