Expected Value Calculator for Stocks
Introduction
Expected Value (EV) is a concept that helps investors evaluate potential investments by weighing different possible outcomes by their probabilities. This calculator helps you estimate the expected value of a stock investment based on various scenarios.
Expected Value Formula
The expected value is calculated using:
EV = Σ(Outcome × Probability)
Where:
- EV is the expected value
- Outcome is the potential return (positive or negative) for each scenario
- Probability is the likelihood of each outcome occurring
Note: The sum of all probabilities should equal 100%.

Scenarios
Define different scenarios and their probabilities. The total probability must sum to 100%.
Scenario 1 (Bull Case)
Scenario 2 (Base Case)
Scenario 3 (Bear Case)
Warning: The total probability should equal 100%.
Understanding Expected Value for Stocks
- Expected Value helps quantify the average outcome you can anticipate from an investment given various scenarios.
- A positive expected value suggests the investment has a statistical edge over time.
- The accuracy of your expected value calculation depends on how realistic your scenarios and probability estimates are.
- Consider factors like company fundamentals, industry trends, and market conditions when defining your scenarios.
- This calculation ignores dividends, transaction costs, and taxes, which should be considered for a complete analysis.
- Remember that expected value is a theoretical concept and actual results may differ significantly.
