The volatility of a stock is often measured by its beta value. More information about beta values is provided below. The table below gives beta values for five stocks. Complete? (a) and? (b).

Company A B C D E

Beta 0.35 0.66 1.35 2.66 5.03

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)=β0+β1(% weekly change in S&P 500 Index)+ε

The? least-squares regression estimate of the slope b1 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.

D. The stocks of companies A and B move about 35% and 66% more than the overall? market, respectively. The stocks of companies? C, D, and E move about 35%, 166%, and 403% more than the overall? market, respectively.
