Repeat Problem 2 using the data below for Qualcomm Inc. However, this time you should create a copy of your worksheet to use as a template. Replace the data for Chevron with that of Qualcomm.

a. Do you think that Qualcomm can maintain the current growth rates of sales and net income over the long run? Why or why not?

b. Which company was more profitable in 2010? Which was more profitable if you take a longer view? Would this affect your desire to invest in one company over the other?

Problem 2

In your position as research assistant to a portfolio manager, you need to analyze the profitability of the companies in the portfolio. Using the data for Chevron Corporation below:

a. Calculate the net profit margin for each year.

b. Calculate the average annual growth rates for revenue and net income using the GEOMEAN function. Is net income growing more slowly or faster than total revenue? Is this a positive for your investment in the company?

c. Calculate the average annual growth rate of total revenue using the AVERAGE function. Is this result more or less accurate than your result in the previous question? Why?

d. Create a Column chart of total revenue and net income. Be sure to change the chart so that the x-axis labels contain the year numbers, and format the axis so that 2010 is on the far right side of the axis.
