However, please note that codes, tables, figures and appendices do not count against the word limit. Assessment weighting: 70% Submission deadline: Tuesday, 25 June 2024 before 12:00 (UK time) Marks released by: Tuesday, 23 July 2024 (we will aim to release marks by this date, but in the event of an unavoidable delay a message will be posted on the module page) Instructions start overleaf. Page 1 of 7 IB93F0 INSTRUCTIONS Please read all instructions carefully. The objective of the project is to allow students to apply skills in gathering, clean- ing, analysing and presenting data; in formulating and testing hypotheses; and in interpreting results through the lens of empirical and statistical analysis. As such, the project is designed to help you acquire transferable skills relevant for writing your dissertation. An important aspect of this exercise is the economic interpretation of results and their discussion in the context of the strengths and weaknesses of the tests themselves. The quality of the interpretation is as impor- tant as the empirical analysis and the results. Please note that the task is very open-ended: there is no guarantee that you end up having the same or similar em- pirical results compared to what has been documented previously. While you should check the accuracy of your analysis, it is very likely that your results will differ from the existing literature and you should proceed and try to interpret your findings by relating them to the concepts covered in class. There are three research topics provided and you must choose ONLY ONE topic to analyse and write a report on . Format The report should follow the format of academic research papers, i.e. it should con- tain abstract, introduction, literature review, methodology, results, conclusion, and references. Figures and tables must be self-explanatory (again, following the format or academic research papers). That is, they should have a title and a descriptive caption. Software and good programming practice You are free to use any software to solve the assignments. MATLAB is available to students to install via WBS. If you have issues please contact the programme team. When coding, please remember to follow good programming practices, including: • Use a consistent indentation style. • Use descriptive variable and function names, with appropriate prefixes. • Comment all function inputs and outputs and comment other parts of your code where appropriate. • Consider writing little functions for pieces of code that are used repeatedly. Submitting your work Before you submit your assessment, you should ensure you are familiar with the guidance and rules in the “Your Assessments” section of your Student Handbook, paying particular attention to: Page 2 of 7 IB93F0 • Inserting a completed assignment coversheet as the first page of your submis- sion. • Academic integrity (including plagiarism). • Referencing. • Word count policy and formatting. • Confidentiality of your work. • Extensions and late submission of work. • Guidelines for online submission. In addition, please adhere to the following instructions: • Upload a single PDF to ‘Individual Project’ for the written answer. • Put all coding-related work files into one single folder without any subfolders, and upload it as a .zip file to ‘Data File.’ The folder name must be your student ID. The folder needs to contain all relevant files including files with data. • Within the folder, use one single file that produces all results once the folder is unzipped. The file name must be your student ID. Check that the file runs without error. Mitigating circumstances Mitigating circumstances MUST be submitted within 20 working days following the submission deadline. Mitigating circumstances not submitted by the relevant dead- line are not required to be considered by the School/Department and may have to be considered by an Academic Appeals Committee as part of an academic appeal—for further information, please see: Use of artificial intelligence For this assessment, AI is: PERMITTED The University recognises an increasing number of technologies such as Artificial Intelligence and that they may be applicable in your completing this assessment. The assessment brief sets out specific requirements or restrictions, and your student handbook has further guidance and advice. You are reminded that the inappropriate use of such a technology may constitute a breach of University policy, such as the Proofreading Policy or Regulation 11 (Aca- demic Integrity). If you breach these policies, it may have significant consequences for your studies. Please make sure you read and understand the assessment brief and how AI may or may not be used. If a generative AI or similar is permitted and has been used you MUST make clear why you used such a tool or service, what you used it for and you will be obliged to confirm that you take sole intellectual ownership of any submitted work. As Page 3 of 7 IB93F0 appendices, and as part of your submitted work, you must provide screenshots of the question and the AI-generated response, alongside an explanation of how the content has been utilised. You should note the relevant reference alongside each screenshot. When you submit you must complete (physically or electronically) a declaration. This requires you to explain the use of any AI. Failure to disclose at the point of submission may be prejudicial in any later investigations should they arise. If you use a generative Artificial Intelligence (AI) in the process of completing this assessment you MUST set out clearly the following: • WHY you used a generative AI • WHAT it was used for • WHICH AI was used; and • If any generated content has been used directly in this submission, if so where. Note that this declaration does NOT contribute towards the word count for the as- sessment. You will also have to confirm in your declaration that the work remains yours and you have intellectual ownership of it. You may be called for viva or other interview to demonstrate such intellectual ownership. A failure to disclose the use of AI, or the use of a misleading description of its use may have significant consequences for your studies. As a result, keeping good records of your interactions is strongly advised. Your assessment starts overleaf. Page 4 of 7 IB93F0 Topic I Momentum in currencies. Background: A large body of literature documents evidence of stock return pre- dictability based on a variety of firm-specific variables. Among these anomalies, the price momentum effect is probably the most difficult to explain within the context of the traditional risk-based asset pricing paradigm (see, e.g., Jegadeesh and Titman (2001) ). Menkhoff, Sarno, Schmeling and Schrimpf (2012) document momentum returns in currency markets that, however, are not easily exploitable. Research objective: Examine whether momentum effects are still present in currency markets. Discuss potential issues with regards to exploiting momentum returns. Data: A suitable cross-section of currency returns for the period January 2000 to December 2022. Potential empirical methods: Portfolio sorts, Fama-MacBeth regressions.

Titman (2001): “Profitability of momentum strategies: An evaluation of alternative explanations,” The Journal of Finance, 56, 699– 720. • Menkhoff, L., L. Sarno, M. Schmeling and A. Schrimpf (2012), “Currency momentum strategies,” Journal of Financial Economics, 106(3), 660–684. Continued . . . / Page 5 of 7 IB93F0 Topic II Post-earnings announcement drift PEAD. Background: No other single event has been found to explain more of the cross- sectional variation in stock returns than the earnings announcement. Earnings an- nouncements are the primary mechanism through which public companies provide periodic financial performance updates to investors. It is therefore not surprising that a considerable body of academic research examines the relation between stock prices and earnings. PEAD refers to the phenomenon of abnormal stock returns’ ten- dency to be positive (negative) in the months following positive (negative) surprise earnings announcements. Ball and Brown (1968) first documented this phenomenon using annual earnings announcements. More recently, Daniel, Hirshleifer, and Sun (2020) and Bryzgalova, Huang, and Julliard (2023) show the importance for PEAD to price the cross-section of stock returns. Research objective: Examine whether the PEAD is still an observable phenomenon, discuss the potential explanations, and evaluate whether it is a violation of market efficiency. Data: Pick 50 US firm and collect stock returns and accounting information from the CRSP and COMPUSTAT for the period of January 2000 to December 2022. Potential empirical methods: Event study.

Background: How do firms choose their capital structure? This is a fundamental question in financial economics and, indeed, the question is at the heart of the “cap- ital structure puzzle” put forward by Myers (1984). Much of the research since the seminal work of Modigliani and Miller (1958) has focused on testing the im- plications of two traditional views of capital structure: the static trade-off model, in which firms form a leverage target that optimally balances various costs (e.g., financial distress costs, stockholder-bondholder agency conflicts) and benefits (e.g., tax savings, mitigated manager-shareholder agency costs) of debt, and the pecking order of Myers and Majluf (1984), in which firms follow a financing hierarchy de- signed to minimize adverse selection costs of security issuance. Research objective: Explain the heterogeneity in observed capital structures across firms by identifying determinants and associating them with firm leverage. In par- ticular, discuss/illustrate the importance of firm fixed effects.
