Textbook Question
Chapter 2, Problem 49SE
The term Beta refers to a measure of a stock’s price volatility relative to the stock market as a whole. A Beta of 1 means the stock’s price moves exactly with the market. A Beta of 1.6 means the stock’s price would increase by 1.6% for an increase of 1% in the stock market. A larger Beta means the stock price is more volatile. The Betas for the stocks of the companies that make up the Dow Jones Industrial Average are shown in Table 2.17 (Yahoo Finance, November 2014).
Table 2.17 Betas for Dow Jones Industrial Average Companies
- a. Construct a frequency distribution and percent frequency distribution.
- b. Construct a histogram.
- c. Comment on the shape of the distribution.
