Instructions on Final Project
Option 1: Coding based project-Backtesting a trading signal (number of students: 3-6)
The purpose of this project is to help you get in hands with the quantitative trading strategies
in practice. You need to use the knowledge you learned in lectures to construct your own
portfolio and trading strategies and backtest your strategy using programming language
(Python, Stata, SAS, R etc.). Submit your written report (3-5 pages), with your program code,
program output, and other related supporting materials on or before the due date, 10:00 pm 29th
February, 2024.
Handling Data:
Step 1: Constructing the sample
1. Quant signal selection, you can use either an existing one (e.g. accruals, Piotroski F-score,
the Magic formula), a composite score from multiple signals you learn from the class, or you
may come up with your own trading signal (with bonus grade 3 points).
2. Download financial data from COMPUSTAT and the market data (i.e. stock returns) from
CRSP from 1980-2023.
3. Screen the data
e.g. Remove tiny stocks by requiring market value>1 million and/or price>1 dollar
e.g. Remove non-sensible observations with negative sales/assets (obvious data errors)
e.g. Remove firms from financial and utility industries, as they are highly regulated
Step 2: Describe your data
1. Please calculate the Mean, Median, Variance, 25% and 75% of the distribution of your
trading signal variable and stock return variable.
** Please don t forget to scale your trading signal variable by either asset or market
value. Otherwise, you only pick up the scaling effect.
2. Please present the correlations among your trading signal variable and other common
firm characteristics, including book value of firm, market value of firm, book-to-market
ratio, various financial ratios (such as asset growth, leverage ratio, return on assets,
sales growth etc.).
Step 3: Backtest: Perform portfolio analysis based on your (historical) data
1. Please use market adjusted returns to proxy for abnormal returns (see class note).
Bonus grade (1 points) will be given if you can use size and B/M adjusted returns to
proxy for abnormal returns.
2. Each year, sorting firms into deciles (i.e. 10 portfolios) according to your trading
signal
3. Each year, calculating simple average abnormal return (i.e. equal weighted portfolio
1
2
return) for each decile and the hedge return (i.e. the difference in abnormal returns
between the long decile and the short decile, ALPHA) based on your trading signal.
a) If your trading signal is a positive return predictor decile one is associated with
the lowest future stock return (short) and decile 10 is associated with the highest
stock return (long)
b) If your signal is a negative return predictor decile one is associated with the
highest future stock return (long) and decile 10 is associated with the lowest stock
return (short)
4. Please plot the hedge return (alpha) each year from 1980-2022 and describe the trend
of the hedge returns
5. Based on time-series hedge returns in step 4 (i.e. 43 observations), please calculate the
mean average abnormal return (average alpha) and associated t-statistics (=mean
average abnormal return/standard deviation; the higher the larger the Sharpe Ratio)
across 1980-2022.
Written report (in 3-5 pages, font 12, double spaced, the number of pages for program
and output is unlimited)
Please explain
1) The rationale of your trading signal. Do you expect it to be a positive or a negative stock
return predictor? Why?
2) Please describe descriptive statistics.
3) Please describe the correlations among your trading signal and other firm characteristics.
4) Please describe the results of your portfolio tests.
a) How many years out of 43 years can your trading signal generate positive alpha? Do
you observe any time-trend pattern (e.g. declining magnitude of alpha)?
b) Can your trading strategy generate statistically significant alpha in your sample period?

Option 2: Coding based project-Predicting fundamentals (number of students: 3-6)
The purpose of this project is to help you get in hands with the quantitative predictive analytics
in practice. Your objective is to predict a fundamental variable (i.e. earnings, revenue, cash
flow from operation or other metrics you are interested*** Again, please scale your variable
by either asset or market value) using programming language (Python, Stata, SAS, R etc.) for
a large scale of data. Submit your written report (3-5 pages), with your program code, program
output, and other related supporting materials on or before the due date.
Handling Data:
Step 1: Constructing the sample (panel data)
1. Download financial data from COMPUSTAT and the market data (i.e. stock returns) from
CRSP (if necessary) from 1980-2023.
2. Screen the data
e.g. Remove tiny stocks by requiring market value>1 million and/or price>1 dollar
e.g. Remove non-sensible observations with negative sales/assets (obvious data error)
Step 2: Describe your data
1. Please calculate the Mean, Median, Variance, 25% and 75% of the distribution of your
dependent (Y) and independent variables (Xs).
2. Please present the correlations among your Y and X variables.
Step 3: In-sample prediction
You may try different combinations of predictive variables you expect to forecast Y
For each trial, please specify Y (target) and Xs (predictive variables) of your predictive
model (i.e. Y=a+b1X1+b2X2+b3X3 ).
1. For each trial, please run OLS regression. Any other methods are encouraged.
2. For each trial, please describe the economic (i.e. magnitude of the coefficients on your
predictive variables) and statistical significance (i.e. t-stat and p-value associated with
the coefficient of each predictive variable).
3. For each trial, please describe the overall fitness of the model (i.e. adjusted R-square).
Written report (in 3-5 pages, font 12, double spaced the number of pages for program
and output is unlimited):
Besides describing results mentioned above.
1) Please explain the rationale of your choice of each predictive variable. Do you expect it to
be a positive or a negative Y predictor? Why?
2) Please describe descriptive statistics.
3) Please describe the correlations among X and Y variables.
Option 3: Non-coding based project (number of students: 3-6 students)
You will prepare a detailed analysis of earnings quality of a company. Select a firm in which
you have a particular interest. Assess its attractiveness from the perspective of a hedge fund
specializing in US equity and focusing on value investing. Concluding your findings in the
form of an Analyst Recommendation (Buy, Sell, or Hold).
DESCRIPTION
The team will be analyzing a company s annual report for consecutive 5 years. The team must
prepare a prospectus of not more than 12 pages (font 12, double spaced), including title page,
which describes the team s analyses and recommendations. A prospectus is a short description
of the analyses and must include the following sections: 1. Executive Summary 2. Earnings
Quality Analysis 2. Conclusions/Recommendations
SECTION 1: EXECUTIVE SUMMARY
This section provides a brief overview of the company. Participants are not limited but, at a
minimum, should provide the following information for both companies:

Date of the annual report (10-K) filing according to the financial statements provided
The primary products(s) and/or services (s) of the corporation
The major competitors of the corporation
SECTION 2: EARNINGS QUALITY ANALYSIS
Your project should demonstrate evidence of detailed financial analysis of firm data.
Integration of tools and concepts acquired in this and other courses (e.g., financial ratio, vertical
analysis, horizontal analysis, cash flow analyses and analyst forecasts) will enhance your grade.
Your project should also include some form of benchmarking, that is, comparison to other
similar firms or circumstances.
Please analyze major accounts on the Balance Sheet and Income Statement, and also read the
Cash Flow Statement to see whether you can locate the trace of possible earnings misstatement.

Incentives:
Any change of auditors, CEO/CFO?
4
Earnings are just above an important benchmark (such as analyst forecast, zero or last
year s earnings)?
Issuance of capital (equity or debt) or any M&A transaction?
Balance Sheet:
Abnormally high accrual or low accruals for each individual accruals account?
Any cookie jar reserve or reverse of the reserve?
