Chapter 7, Problem 22PS

Stock betas There are few, if any, real companies with negative betas. But suppose you found one with β = –.25.

  1. a. How would you expect this stock’s rate of return to change if the overall market rose by an extra 59%? What if the market fell by an extra 5%?

  2. ii. Invest $20,000 in stocks with β = 1.
  3. iii. Invest $20,000 in the stock with β = –.25.
