Financial Accounting Discussion #2 Help

I need help with this discussion question that's due tomorrow 2/5/15 by 11:59PM. The reading that goes along with this discussion is from page 343 in the textbook by Ross, S. A., Westerfield, R. W., Jaffe, J. F., & Jordan, B. D. (2014). Corporate finance: Core principles and applications (4th ed.). New York, NY: McGraw-Hill. ISBN: 9780077861650. I have posted the discussion topic  and response guidelines below. Many thanks in advance!

Activity Instruction

Discuss beta and its importance. What type of investors would invest in a high beta stock and a low beta stock? Also, in your textbook, review the Real World case, focusing on "Beta, Beta, Who's Got the Beta?," on page 343. Is beta a useful tool? Why were the beta estimates discussed in the reading different?
