Data Tables
Introduction to Data Tables
Data tables are tools used to perform sensitivity analysis.
They allow examination of output data (e.g., a company's EPS) impacted by changes in input variables (e.g., revenues, gross margin assumptions).
Data tables output results in a presentation-friendly matrix, commonly used by analysts to illustrate a range of possible output values.
Example of Data Tables
Illustration of assumptions before data table construction:
Revenue growth ranges.
Cost of goods sold margin assumptions.
Resulting data in the table showcases earnings per share (EPS) implications based on variations in cost of goods sold margins and revenue growth rates.
Types of Data Tables
Three primary types of data tables exist:
Vertical Data Table
Layout:
Input assumptions listed on the left (e.g., revenue growth rates).
Output variable (EPS) placed one row above the results column.
Process:
Highlight entire table for execution.
Indicate only the input variable's cell, e.g., replace revenue assumption in cell F25 with input values for analysis.
No row input cell is needed in this type of data table.
It's necessary to hit F9 for recalculation if Excel’s settings are manual.
Data table must be created within the same worksheet as input variables.
Horizontal Data Table
Layout:
Output variable on the left, directly followed by results on the right.
Input assumptions are listed above.
Process:
Highlight the entire table.
In the row input cell area, indicate the input variable's position (e.g., revenue growth rate).
Column input cell does not need to be specified in this layout.
Similar in function to the vertical table, results are displayed in the organized output.
Two-Sided Data Table
Layout:
Output variable located at the top left.
Input assumptions for one variable organized horizontally to the right and for another vertically below.
Process:
Highlight entire area of assumptions.
Indicate both row and column input cells when running the data table. For example:
Column input might link to revenue growth rates in F32.
Row input could link to project assumptions for cost of goods sold margin.
The procedure executes multiple calculations to display outputs.
Recalculation via F9 is still applicable after setup.
Excel Implementation Example
Setting up a practical example using Excel involves:
Creating Scenarios
Use a drop-down menu to select scenarios (e.g., best case, base case, weak case).
Implement the OFFSET and MATCH functions to determine the appropriate revenue growth rates and costs of goods sold margins based on the selected scenario.
Building Data Tables
Guide users through practical steps to build their data tables in Excel:
Initiate the setup for a vertical data table first where assumptions are placed accordingly.
Highlight the relevant areas and execute the data table command.
Confirm input variables and ensure accurate output calculation.
Organize the next data table horizontally and repeat similar steps to ensure consistent results.
Finally, construct a two-sided data table following the provided layout, ensuring all assumptions are accounted for in their respective slots.
Conclusion
Utilizing data tables in Excel provides a clear, concise method to conduct sensitivity analysis.
It is crucial to follow correct procedures for data input and calculations to ensure accurate outputs for decision-making processes.
The understanding of these principles is essential for effective financial analysis in practice.
