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)

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.
