Imagine you wish to estimate the betas for two investments, A and B. You have gathered the following return data, E, for the market and for each of the investments over the past 10 years, 2008-2017 a. On a set of market return (x-axis)-investment return (y-axis) axes, use the data to draw the characteristic lines for investments A and B on the same set of axes. b. Use the characteristic lines from part a to estimate the betas for investments A and B. --- a. The equation of the line for asset A is YA = **Market + (Round to two decimal places.)
