Chapter 13 Hwfollow The Instructions On Using Excel To Create A Regres

Chapter 13 HW Follow the instructions on using Excel to create a regression equation and retrieve historical data on Yahoo (see the files under Module 11) for this assignment. The Walmart Regression file under module 11 is a sample of how your completed task should look. Instructions Pull the historical data on your favorite company at Yahoo Finance ( ) or any website for January 2022 to December 2022, and use the monthly closing stock prices to find the following. Show your work in Excel (the equations should be embedded under the cells containing the following values): 1. Find the slope (a) and intercept (b). 2. Create the linear regression (equation). 3. Predict the stock price at the close of December 2023 (show your work leading to the price) Submit your assignment in Excel with the historical monthly data in the following columns. Include the name of the company whose stock price you predict and the website link where you retrieved the historical data. Be sure items 1 to 3 above are also included in your submission. Use the columns below: Column 1 = Date Column 2 = Open $ Column 3 = Low $ Column 4 = Close $ Column 5 = Month (x)

Paper For Above instruction

In this assignment, the primary goal is to utilize Microsoft Excel to perform a linear regression analysis on historical stock data and make a future price prediction. The process involves multiple steps: gathering relevant data, performing regression calculations, and interpreting the results to forecast stock prices. This practical application demonstrates core statistical concepts, such as calculating the slope and intercept of a regression line, constructing the regression equation, and employing the derived model to predict future stock values.

Step 1: Data Collection

The first step involves collecting historical stock data for a specific company, ideally for the period from January 2022 to December 2022. Data can be retrieved from Yahoo Finance or other reputable financial websites. The required data points include the date, opening price, lowest price, closing price, and the month number (x). The month number acts as the independent variable in the regression model, representing time progression. Proper organization of this data in an Excel worksheet is essential, with columns labeled clearly to facilitate analysis. For illustration, suppose the dataset includes monthly closing prices for a chosen company like Apple Inc. (AAPL). The data should be arranged sequentially from January 2022 to December 2022 in the following format:

  • Date
  • Open Price ($)
  • Low Price ($)
  • Close Price ($)
  • Month (x)

Step 2: Calculation of Regression Parameters

The core of the project is calculating the regression parameters—specifically, the slope (a) and intercept (b)—using Excel formulas. The slope indicates the average change in stock price per month, while the intercept represents the estimated price at the starting point (month zero). Using Excel functions such as SLOPE() and INTERCEPT(), input the array of monthly closing prices (dependent variable) and the corresponding month numbers (independent variable). For example:

=SLOPE(range of Close Prices, range of Month numbers)


=INTERCEPT(range of Close Prices, range of Month numbers)

Embedding these formulas directly under the data ensures transparency and allows for validation of calculations. This step produces the regression coefficients necessary to formulate the linear equation.

Step 3: Creating the Regression Equation

With the slope (a) and intercept (b), formulate the linear regression equation: Price = a * Month + b. This equation models the relationship between time (months) and stock prices, enabling prediction of future values. Display this equation clearly within the Excel sheet for reference. For example, if the slope is 2.5 and the intercept is 150, the regression equation becomes:

Price = 2.5 * Month + 150. This model reflects the anticipated trend in stock prices over time based on historical data.

Step 4: Future Price Prediction for December 2023

Predicting the stock price for December 2023 involves identifying the value of 'Month' corresponding to December 2023. If January 2022 is Month 1, then December 2023 corresponds to Month 24 (for 2022) plus 12 (for 2023), totaling Month 36. Substituting this in the regression equation yields:

Predicted Price = a * 36 + b

Calculate this in Excel, ensuring the use of the already computed regression coefficients. Show your detailed work, including the substitution process, to demonstrate the prediction methodology clearly.

Step 5: Final Submission

The completed Excel file should contain the original monthly data, the formulas used for regression calculations, the regression equation, and the predicted future stock price. Additionally, include the name of the company whose stock price you predicted and provide the URL where the historical data was obtained. This comprehensive document showcases your understanding of regression analysis and your ability to apply it effectively for financial forecasting.

In conclusion, this practical exercise underscores the importance of statistical tools in financial analysis. By mastering Excel regression functions, students can analyze trends, forecast future performance, and develop data-driven investment strategies. Accurate data collection, precise application of formulas, and clear explanation of process are critical components for successful completion of this assignment, reflecting the core principles of quantitative analysis in finance.
