Graphical derivation of beta

A firm wishes to extimate graphically the betas for two assets, A and B. It has gathered the return data shown in the following tables for the market portfolio and for both assets over the last 10 years, 2006-2015.

Year	Market Portfolio	Asset A	Asset B
2006	6%	11%	16%
2007	2	8	11
2008	-13	-4	-10
2009	-4	3	3
2010	-8	0	-3
2011	16	19	20
2012	10	14	22
2013	15	18	29
2014	8	12	19
2015	13	17	26

a) ON a set of "market return (x axis) - asset return ( y axis)" axex, use the data given to draw the characteristic line for asset A and for asset B.

b) Use the characteristic line from part a to estimate the betas for assets A and B.

c) Use the betas found in part b to comment on the relative risks of assets A and B.
