Course Description
This course offers the financial theory and quantitative tools necessary for understanding how stock, bond prices are determined, and how financial assets are used for investment decisions. Topics covered include modeling the relation between risk and return, optimal portfolio selection based on mean–variance analysis, asset pricing models, money management, and more. The focus is mainly on common stocks, but fixed income securities (bonds) and derivative securities (options, futures) are also analyzed.
The course is quantitative and challenging. Rather than delving into the details of current practice, it takes a rigorous and critical view to the process of investing. The aim is to provide the students with a lasting conceptual framework in which to view and analyze investment decisions. At the same time, the course will discuss alternative philosophies of investing, and relate the material to current financial news and to problems relevant to the practitioner.

Project:
One of the main goals of this class is to promote learning by doing and team work. They are all vital skills for your future success. To achieve this goal, I will assign team of 4-6 to prepare a class project on a pre-specified topic. The class project last for the whole course, with a mid-term progress presentation, a final group presentation and a final report due. The mid-term presentation is to guide you through your preliminary analysis and provide insights to further improvement. The final report includes the in-class final presentation and a written report which summarized the project.
- Nature of the project
The project covers roughly three stages:
- Collection relevant information of which the most important one is data collecting.
- Strategy developing and back-testing
- Feasibility analysis of implementation
- Team management
- Requirement for final report
The final written reports should have the following format:
- Executive summary
- Why choose this idea?
- Major issues, challenges
- Your results, and conclusion
- Data and methodology
- Data collection (source, and procedure)
- Data cleaning (make sure data is making sense and no error)
- Simple descriptive statistics to show the major statistical property of your data
- Methodology describe how you handle your data, i.e. statistical models, portfolio construction methods etc.
- Show your analysis and results
- Robustness test etc.
- Various other related analysis
- Data analysis and results
- Conclusion
- Presentation requirements
Despite the class project is more technical orientated, a good presentation skill is required and a formal dressing code for presentation is enforced.

To tech the trading strategy, you need to collect historical data and construct portfolios which represent your trading strategy; then track the returns of your portfolios over time. To measure the performance of your strategy, you need to do risk adjustment (adjust for beta, use sharp ratio etc.). It is a good idea to show sub-period analysis to test to see if your results are robust (i.e., the results based on full sample period is applicable to sub-sample periods). Finally, you need to consider more realistic settings such as considering the impact of transaction cost and potential price impact.
The starting point of your project is to understand the effect that you are going to test. These are all well-known market “anomalies” based on studies on US data. So search the research journal on the topic will be your starting point. You can follow the procedure of the papers to construct you portfolio.
The progress of the project last the whole module. By week 5, I expect you to 1. Finish the introduction and literature review. 2. Already collected the data or report your data collection progress. 3. Has figured out the methodology to test your strategy. And these are the results you report in your mid-term project progress presentation.
