What the calculation uses
- Month-end closing prices in US dollars, adjusted for stock splits
- Price return only: dividends are not included
- Shares are bought at the close of the last trading day of the month, including fractions of a share
- Full calendar years only, here 2007 to 2025
- Prices from Financial Modeling Prep, as of 12 Nov 2026
The return per year is the constant annual rate at which the amount would have grown to the same value in the same time.
How it is calculated
- Once: shares = amount ÷ closing price at the end of the previous year
- Every month: shares += instalment ÷ month-end closing price
- Value = shares × closing price at the end of the last year
- Value today = the same shares × latest closing price
- Largest decline = lowest close ÷ highest close before it − 1
This is a calculator using past prices, not a forecast, not a price target and not a recommendation to buy or sell this stock. Past performance is not a reliable indicator of future results. Calculated with month-end closing prices in US dollars, without dividends, costs or taxes; if you invest in euros, you also have currency gains or losses.
