The continuously compounded annual return on a stock is normally distributed with a mean of 28% and standard deviation of 30%. With 95.44% confidence, we should expect its actual return in any particular year to be between which pair of values? Hint: Refer to Figure.
multiple choice
A. −32.0% and 88.0%
B. −20.0% and 88.0%
C. −62.0% and 118.0%
D. −2.0% and 58.0%
The next year's return on stock X is expected to be either -7% with probability 0.2 or 20% with probability 0.8. Find the stnadard deviation of the returns.
a.12.37% b.11.10% c.12.88% d.11.69% e.10.80%
Suppose that the annual return for
particular stock follows the same
distribution every year, and that the
return for any given year is
independent of the returns for any
prior years. Based on an analysis of
the stock's annual returns over an
12 year period, it is determined that
the 95% confidence interval for the
stock's expected annual return is
given by (-0.1724, 0.2861). Find the
volatility of the stock. Use the
approximation formula from Berk
and DeMarzo.

- You build a binomial model with one period and assert that over the course of a year, the stock price will either rise by a factor of 1.5 or fall by a factor of 2/3.

Stock B has expected return 20% and s.d. 15%. The two stocks have a correlation coefficient of 0.5. 1.Note that Stock A has greater risk (s.d.) that Stock B, but a lower expected return. Explain how is this possible in a world where returns on assets are as predicted by the CAPM. 2. Determine the expected return and the s.d. of portfolio P1, composed by investing 30% in stock A and 70% in stock B. 3. Consider stock C that has expected return 15% and s.d. 15%.
