a time line
Using a time line The financial manager at Starbuck Industries is considering an investment that requires an initial outlay of $25,000 and is expected to result in cash inflows of $3,000 at the end of year 1, $6,000 at the end of years 2 and 3, $10,000 at the end of year 4, $8,000 at the end of year 5, and $7,000 at the end of year 6.
· a.Draw and label a time line depicting the cash flows associated with Starbuck Industries’ proposed investment.
· b.Use arrows to demonstrate, on the time line in part a, how compounding to find future value can be used to measure all cash flows at the end of year 6.
· c.Use arrows to demonstrate, on the time line in part b, how discounting to find present value can be used to measure all cash flows at time zero.
· d.Which of the approaches—future value or present value—do financial managers rely on most often for decision making? Why?

Risk preferences Sharon Smith, the financial manager for Barnett Corporation, wishes to evaluate three prospective investments: X, Y, and Z. Sharon will evaluate each of these investments to decide whether they are superior to investments that her company already has in place, which have an expected return of 12% and a standard deviation of 6%. The expected returns and standard deviations of the investments are as follows:
Investment  Expected return  Standard deviation 
X  14%  7% 
Y  12  8 
Z  10  9 
· a.If Sharon were risk neutral, which investments would she select? Explain why.

Rate of return, standard deviation, and coefficient of variation Mike is searching for a stock to include in his current stock portfolio. He is interested in HiTech, Inc.; he has been impressed with the company’s computer products and believes that HiTech is an innovative market player. However, Mike realizes that any time you consider a technology stock, risk is a major concern. The rule he follows is to include only securities with a coefficient of variation of returns below 0.90.
Mike has obtained the following price information for the period 2012 through 2015. HiTech stock, being growthoriented, did not pay any dividends during these 4 years.
