MGMT20005-Business Decision Analysis
Assignment 2: Group Assignment
Introduction: This is a group assignment of up to 3 students (1-3 students) from the same tutorial group. You are also allowed to form a group with students of the same tutor. Note that if the group is formed with students of different tutors, you will receive zero marks for this assignment. You can complete your assignment individually, if you wish, however, you are strongly encouraged to complete this assessment in a group setting.
Weight: 25% of the total mark.
Format: Slide deck (.pptx/.pdf) + Recorded presentation (.mp4) + Excel workbook (.xlsx).
Due date: 5 pm Thursday, Week 11.
Submission: Only one submission (including all your files) is required per group. Make sure you include the names and student numbers for all team members on the front slide of your slide deck file submission; otherwise, a penalty will be applied!
Late submission: It will attract a marking penalty. A 10% penalty will be applied for every day of late submission for up to a maximum of 4 days. Assignments submitted later than 4 days after the due date will not be marked and will receive no mark.
Extension (Special consideration): No further extension will be provided for this assignment (since this is a group submission, no extension will be provided even for individual work). Special considerations submitted to the faculty will be considered for re-weighting to the exam.
Submission format and word limit, and instructions:
1. Prepare your submission using Microsoft PowerPoint (or similar presentation software). You can use up to 30 slides and up to 2,500 words in your slides altogether (excluding figures, tables, references, and appendices); however the 30 slides limit still applies). Your slides should be well-organised, coherent, and visually appealing. Please note that it is essential to address all the requirements in your submission. The awarded grade will be applied to all students in that group.
2. A maximum of a 5-minute recorded presentation outlining your analysis and assessment of your portfolio optimisation methods used. You may choose to use the same deck of slides that you and your group have prepared (or a revised slide deck) if you find this suitable and appropriate for the 5-minute presentation. You must submit an .mp4 file (or a similar format) for your video presentation. It is also a requirement to include your face(s) in the presentation recording. Note that in group submission, one student can record on behalf of the group, or students can share the responsibility of recording.
3. Ensure that all your files - Excel, slide deck (in .ppt or .pdf), and video (in .mp4 format) - are submitted together in a single submission through the Upload function on Canvas. Do not upload the video file separately in the 'Media' section. Canvas only allows you to upload files from one category per submission. If you submit files in both the 'Upload' and 'Media' sections, only one set of files will be submitted, which may result in missing parts of your work. To avoid this, please upload all files (including the video) using the Upload function and check whether you can view all your files in your submission.
Assignment Details
This assignment is designed to let you explore and evaluate a number of approaches for portfolio optimisation, using live real-world data from DatAnalysis Premium (Australian company financial data) and/or Orbis (foreign company financial data). In this assignment, you are required to use asset return data from a period of 5 years to identify the optimum portfolio using a variety of different optimisation methods. The assignment slide deck should include three main sections: Preliminary Work, Optimisation Models, and Conclusion. The requirements of each part are detailed below. The breakdown of marks (a total of 25) is given in this document and as a rubric in Canvas.
Definition - Portfolio Optimisation (Risk and Return): An investment portfolio consists of a collection of investment items (or stocks or assets) held by an individual or organisation, in which the investor seeks to purchase a variety of assets to gain a good return (profit) through increasing asset value. Individual assets vary in value from minute to minute, and whilst over time, they might grow in value, their value fluctuates over time. The possibility of such fluctuations represents a risk to the investor. Accordingly, in portfolio selection, investors should wisely choose to invest across a range of assets, ideally those with a total value that is less liable to fluctuation than the individual assets.
1. Preliminary Work (3 marks: Data collection + Classifications)
The first stage is to identify a set of 10 investment items from which you will subsequently determine optimum portfolios using various optimisation models. You may select any Australian or global assets (including indices) whose data is provided onDatAnalysis Premium(Australian company financial data) and/orOrbis(foreign company financial
data).
To obtain company share price data, please refer to the Financial Data Resources guide compiled by the FBE Library Team. This guide provides step-by-step instructions on how to access and extract historical share prices and financial data from various databases available to University of Melbourne students. You can find this resource from the Assignment 2 folder in Persuall.
The chosen assets must satisfy the following general conditions:
• Each must have at least 60 months (August 2020 - August 2025) of monthly data available, up to and including August 2025.
• They should be selected from any 4 different sectors/categories of your choice (let’s call them S1, S2, S3, and S4), e.g., banking, pharmaceuticals, media, technology, government bonds, property trusts, etc., with at least two assets in each category. Provide clear justification and reasoning for your choices.
• You need to calculate the monthly return of each asset by (Stock_value_new – Stock_value_old)/(Stock_value_old). Then the average return of an asset is the mean of return of that asset over 60 months. Similarly, the risk is calculated as the standard deviation of return over 60 months. A sample Excel file is provided that includes sample data with the calculation of return and risk for 36 months.
• Data should span a reasonable range of volatilities/risks. Classify the assets into 4 groups according to (ascending) risk (let’s call them R1, R2, R3, and R4). A simple classification approach would be to calculate the standard deviation of each asset (as explained in the previous dot point) and define risk categories based on the 4 quartiles. Therefore, R1 should include investment stocks with the lowest risk (lowest standard deviation).
• Recall that each asset lies in one of the Rs and in one of the Ss.
2. Optimisation Models
The assignment requires you to consider two different optimisation techniques: linear programming and mixed integer linear programming. For each optimisation model, explain the optimisation approach taken, the mathematical formulation, and identify how the Excel Solver is to be used (explain any constraints used – e.g., that a variable needs to be an integer or binary, and include any necessary screenshots of how Excel Solver is implemented on your slides).
Mathematical Models
The aim is to achieve the maximum overall return of the portfolio, subject to specified requirements on risk mix (percentages in R1 to R4) and category mix (percentages in S1 to S4). Note that the overall return of a portfolio (or its expected return) is calculated as a weighted average of the expected returns of all assets, where the weights represent the proportions of the portfolio that should be invested in each asset. The following investment guidelines are to be applied:
Part A (9 marks: Mathematical Model + Excel Solver + Sensitivity report + Discussion)
(1) Investment in the highest-risk assets shouldn’t exceed 15% of the portfolio, while at least 30% of the portfolio must be allocated to the lowest risk group. (2) To ensure diversification, each sector category must have a minimum of 10% invested; apart from one sector that you choose (your discretion) to have a minimum of 20% invested.
Use Excel’s reports to comment on binding constraints and the impacts of changes to the risk and category constraints on the optimum portfolio (sensitivity analysis). Further, if an asset(s) is not selected in your optimal solution, explain how much its return should be changed, so that asset can be included in your optimal selection.
Part B (5 marks: Mathematical Model + Excel Solver + Discussion)
(1) At most 2 assets can come from the riskiest and second riskiest group. (2) At least 30% of the portfolio must come from the least risky group. (3) To ensure diversification, each sector category must have a minimum of 10% invested. (4) To offset the risk, if any asset from the riskiest group is selected, then at least one asset from the second least risk group must also be included.
3. Conclusion (4 marks: comparison + conclusion + overall presentation)
Summarise your work (of all the above parts), present all your results comparatively, coherently, and compellingly. Then, based on your assessment of the various approaches, briefly explain a strategy that you might prefer to use for this portfolio optimisation problem. Include a summary table detailing each chosen portfolio and the basis of choice, compare each of your chosen portfolios. You may wish to discuss any shortcomings of the utilised optimisation techniques.
4. Recorded 5-minute Presentation (4 marks)
Imagine you are addressing a distinguished panel of executives at a leading investment firm. Your goal is to present a clear, data-driven asset allocation recommendation based on financial data and optimisation modelling, demonstrating sound analytical reasoning aligned with real-world investment decision-making.
Your task is to create a concise 5-minute recorded presentation about portfolio optimisation strategies. Begin by providing a comprehensive overview of your carefully selected 10 investment items, showcasing your keen understanding of the market landscape. Afterward, briefly explain a preferred portfolio optimisation strategy, providing reasons for your choice and including a summary table comparing each selected portfolio. This presentation should showcase your understanding of investment strategies and your ability to communicate them effectively.
This presentation should showcase your understanding of investment strategies and your ability to communicate them effectively. You may choose to use the same deck of slides that you and your group have put together for submission to support your presentation, if you find this suitable and appropriate. Alternatively, you might consider adapting or creating a slightly different version tailored to this audience and context.
It is also a requirement to show your face/s in your presentation recording for two key reasons. First, it is to help the audience connect with the individual/s behind the analysis conducted; and second, to support academic integrity, as this forms part of a formal assessment task.
You must submit an mp4 file (or similar) for your video presentation. We recommend using Zoom (see Zoom Recording Basics) to record your video presentation, but you may use another tool of your choice and then upload the video file (.mp4) into Canvas in the Assignment submission link with your presentation slides.
Marking guide
Assignments will be marked based on the methodologies adopted and the quality of work. Given the vast range of assets to select from the financial database(s), it is highly unlikely that you will choose the same portfolio of stocks as another student group.
It is important to pay special attention to spelling, grammar, and punctuation to avoid ambiguity and confusion. Students can include relevant graphs, tables, and other exhibits such as appendices. They must be clearly labelled and will not be included in the word count.
