Data & methodology
How does the investment calculator work?
- Enter an investment amount and a start date. We use historical stock prices to calculate how many shares you would have bought, then apply the current price to show your hypothetical portfolio value and return.
What are Historical extremes?
- Max profit: the best buy and sell dates that maximize percentage return. Max drawdown: the largest peak-to-trough decline in price. Return since IPO: total return from IPO date to the latest price.
What is Max drawdown?
- Maximum drawdown is the largest peak-to-trough decline in price. It shows the worst drop from any prior high to a subsequent low. Peak and Trough are the dates and prices at which this decline occurred.
Does this include dividends?
- The calculator uses adjusted closing prices when available, which account for stock splits and dividends. For the most accurate results, we recommend using data that includes dividend adjustments.
Where does the price data come from?
- Historical prices are dividend-adjusted closing prices from our data provider. The calculator and Historical extremes use the same data source for consistent results.
How are the dollar amounts in the cards calculated?
- The dollar amounts in Historical extremes use the investment amount you select in the calculator above (e.g. $1,000). They show what your investment would have been worth at the Buy/Peak/IPO date versus the Sell/Trough/Current date.
