How is the % calculated?
We fetch up to 10 years of historical data. If a stock is newer (like JGPI), we calculate the growth based on its total days on the market.
Note: This is a price-growth calculator. Monthly dividends from income ETFs are not automatically reinvested in this math.
Why does the number look so high? The last decade was one of the strongest bull runs in market history, especially for US tech. A ticker like AAPL or MSFT will show 20–26% because that is what actually happened — not because that is a safe assumption going forward.
Survivorship bias: You are searching for companies you already know succeeded. Companies that failed or were delisted do not appear here. This naturally skews the result upward.
Past performance does not predict future results. Long-term broad market averages (e.g. S&P 500) are closer to 7–10% annually. Use this tool to model scenarios, not to make financial decisions.
