a. For each of the five companies, interpret the beta value. Choose the correct answer below.
A. The stocks of companies A and B move about 42% and 79% as much as the overall market, respectively. The stocks of
companies C, D, and E move about 29%, 166%, and 403% more than the overall market, respectively.
B. The stocks of companies A and B move about 58% and 21% as much as the overall market, respectively. The stocks of
companies C, D, and E move about 129%, 266%, and 503% as much as the overall market, respectively.
O C. The stocks of companies A and B move about 42% and 79% less than the overall market, respectively. The stocks of
companies C, D, and E move about 29%, 166%, and 403% more than the overall market, respectively.
D. The stocks of companies A and B move about 42% and 79% more than the overall market, respectively. The stocks of
companies C, D, and E move about 29%, 166%, and 403% more than the overall market, respectively.

You can estimate the beta value of a stock by developing a simple linear
regression model, using the percentage weekly change in the stock as the
dependent variable and the percentage weekly change in a market as the
independent variable. The S&P 500 Index is a common index to use. For example,
if you wanted to estimate the beta value for a company, you could use the following
model, which is sometimes referred to as a market model:
(% weekly change in company) = Bo
+ B1 (% weekly change in S&P 500 Index) + e
%3D
The least-squares regression estimate of the slope b, is the estimate of the beta
value for the company. A stock with a beta value of 1.0 tends to move the same as
the overall market. A stock with a beta value of 1.5 tends to move 50% more than
the overall market, and a stock with a beta value of 0.6 tends to move only 60% as
much as the overall market. Stocks with negative beta values tend to move in the
opposite direction of the overall market.
