Methodology & Sources

Price data: Historical prices are the closing price on the first trading day of each year, adjusted for splits and dividends (so returns assume dividends were reinvested), from Yahoo Finance and MacroTrends. Current prices come from Yahoo Finance and refresh hourly; if that source is unavailable, the last saved price is used.

Calculation: Assumes a single purchase at the start of 2018 (or the first trading day, for companies that listed that year), held until today. No transaction fees, taxes, or slippage are included.

Benchmarks: The S&P 500 comparison uses the S&P 500 Total Return index (dividends reinvested, like an index fund) at the start of2018 and today. Gold uses the price per troy ounce. Savings account assumes a 2% APY compounded annually.

Inflation adjustment: Uses U.S. CPI-U annual averages from the Bureau of Labor Statistics. The 2026 CPI value is estimated.
