MAT312 Excel Lab #3 – Choosing Stocks with Confidence
NOTE: You need to use Excel functions/tools for this lab rather than just typing
numbers into the cells. Please review the Excel tutorial videos provided in weekly
resources, along with examples provided in Chapter 8, sections 1 and 2, before
attempting the lab.
For your first assignment as an investment analyst intern, you have been asked to write
a report summarizing the performance of two different mutual funds. Your manager is
trying to decide whether to include one of these funds in a client’s portfolio and average
stock performance is one of the key indicators.
The funds you’re researching are the Fidelity Select Pharmaceuticals Portfolio and the
Fidelity Select Gold Portfolio.
The historical fund performance data (given in percentages) is provided in the “MAT312
PART 1
To impress your new boss, you’re going to select a third mutual fund and compare all
three funds. Go to the Fidelity Mutual Funds directoryLinks to an external site. and
select a fund. Once you select your fund, go to the Performance and Risk tab and add
the Historical Fund Performance for at least the past 8 years on the second sheet (“New
Mutual Fund”) in the Excel Lab file provided.
Calculate the descriptive statistics to compare the returns of each fund within Excel.
You will also assess reward by constructing 95% confidence intervals for the population
mean returns. These results should be shown within the Excel Spreadsheet.
Your completed Excel file must be submitted to Canvas through the assignment link.
PART 2
Your new boss has required you to submit a report of your findings. Create a memo to
compare and contrast descriptive statistics for all three funds, such as mean, standard
deviation, max, min, outliers, etc., and provide comments on the reward and risk for
investing in each. In addition, explain the meaning of your confidence intervals in
context. What can you recommend for further analysis?
This should be written as if you were writing a professional report to your employer, not
an outline of tasks you did for a project in stat class. You can find a sample report on
pages 302-303 in the textbook.
