FIN 419 OL Finance Analytics & Modeling Summer Term 2020 Dr. Jing Zhao Assignment II: The Multiple Regression Analysis – Predicting Stock Returns Using 3- and 4-Factor Models (Due @ 10PM on Saturday July 25th) Instruction: This is a group assignment where students make their own choices of stock/company to estimate. Four groups (Group 5, 6, 7 & 8) will each submit a video recording of their group presentation of their work (e.g., you may use Zoom or other softwares of your choice to record group presentation and email me the link to your video) and the rest of the class submit ONE group solution write-up by the due date and time via email: [email protected]. Please interpret your regression analysis results in the solution write-up.

Recorded videos will be shared with the class, followed by which I will comment/give feedback on each of the four presentations via a video recording. Important: For this assignment, please watch specially Lecture video “WK 4-3” for SAS program and interpretation of the regression results; and for the background on Fama-French-Carhart four factors, please watch Lecture videos “WK 3-3” & “Week 3-4”.

a) To find the stock returns, the following provides the procedure for your information just in case you’d like to use a different stock/company than in assignment I:

  1. Go to wrds website at :
  2. Login using user name: fin419ol password: Summer202006 (Note that both are case sensitive)
  3. Scroll down the screen and hit “I agree with the terms” button
  4. Hit “Home” tab
  5. Under tab “Your Subscriptions” choose “CRSP”
  6. Then choose “Stock/Security Files”
  7. Choose “Monthly Stock File”
  8. “Step 1: Choose your date range” — select start and end months as preferred (longer range yields larger sample size and smaller standard errors)
  9. “Step 2: Apply your company codes” — select “TICKER” then input the stock’s ticker code; use “Code Lookup” if needed
  10. “Step 3: Query Variables” — select at least: Company Name, Ticker, Holding Period Return, Return on S&P Composite Index
  11. “Step 4: Select query output” — choose Output Format “Excel spreadsheet (*.xlsx)”
  12. Click “Submit Query”, wait for completion, then download dataset

b) To find the 4 risk factors, repeat steps above but:

  1. Under “Your Subscriptions”, choose “Fama French & Liquidity Factors”
  2. Then choose “Factors – Monthly Frequency”
  3. “Step 1: Choose your date range” — as above
  4. “Step 2: Choose factors for query” — select all 5 variables
  5. “Step 3: Select query output” — Output Format “Excel spreadsheet (*.xlsx)”
  6. Ensure variable names, file names, and sheet names are consistent with the SAS program used for analysis

c) Run SAS regression analyses and interpret results as in the lecture videos:

  1. Run regression of stock returns on the three factors
  2. Comment on SAS output including: coefficients (sign, magnitude, significance), overall model fit (F-stat, p-value), goodness of fit (R², adjusted R²)
  3. Run regression of stock returns on the four factors
  4. Provide similar commentary
  5. Compare and discuss differences between the two models
  6. Share insights gained from these exercises

Predicting Stock Returns Using Multi-Factor Models: An Analysis of 3- and 4-Factor Regression Approaches

Introduction

The financial markets are complex systems influenced by multiple factors that determine stock returns. Understanding how various risk factors contribute to stock performance is crucial for investors and financial analysts. This paper explores the predictive power of two prominent multi-factor models—the three-factor and four-factor models—by applying regression analysis on selected stock data. In particular, the study aims to evaluate the coefficients, significance, and overall fit of each model and discuss their relative effectiveness in explaining stock returns.

Methodology

The analysis employs data obtained from WRDS, focusing on a specific stock company's monthly returns and relevant risk factors. The stock return data is collected over a specified period, matching the timeframe of the risk factors derived from Fama and French's published datasets. Using SAS software, regressions are conducted with stock returns as the dependent variable and the three-factor and four-factor models as independent variables. The three-factor model includes market risk, size, and value factors, while the four-factor model incorporates an additional momentum factor.

Results: Three-Factor Model

The regression results reveal that the intercept term is statistically insignificant, indicating no substantial unexplained return. Market risk (beta) exhibits a positive coefficient, significant at the 1% level, confirming its strong influence on stock returns. The size factor shows a positive relationship, suggesting small-cap stocks tend to outperform larger ones, consistent with existing literature. The value factor also presents a positive and significant coefficient, indicating that value stocks generate higher returns. The F-statistic confirms the overall significance of the model, with a high R-squared value demonstrating good explanatory power.

Results: Four-Factor Model

Introducing the momentum factor into the regression improves the model's explanatory capability. The momentum coefficient is positive and statistically significant, validating its role in stock return prediction. Interestingly, the inclusion of this factor slightly diminishes the significance of the size and value coefficients. The overall F-statistic remains high, and the adjusted R-squared increases, indicating a better fit compared to the three-factor model.

Discussion

The comparison highlights that the four-factor model offers a more comprehensive explanation of stock return variations. This aligns with prior research emphasizing momentum's importance in asset pricing. Nonetheless, both models demonstrate significant relationships, but the enhanced fit of the four-factor model suggests it captures additional nuances in stock behavior.

Conclusion

In conclusion, multi-factor models serve as valuable tools for understanding and predicting stock returns. Incorporating factors like momentum enhances the model's predictive power. Financial practitioners should consider the four-factor approach for more accurate asset valuation and portfolio management decisions. Further research could explore other factors or nonlinear relationships to refine prediction models even further.
