Methodology
The figures on this page use XCEM's historical total-return data from 2015-09 to 2026-09. The tables above use month-end closes, and the latest close so far for a month still in progress.
Returns use adjusted close prices, which account for stock splits and reinvested dividends, the same convention used by major brokerages. End-of-day prices come from EODHD; parts of the deep historical series are carried over from Yahoo Finance data. A "year" scenario invests $1,000 at the prior December's month-end close and values it at the latest close. Amounts in other currencies are converted at month-end exchange rates published by the European Central Bank and, for earlier years, the Federal Reserve: into US dollars at the buy date's rate and back at the sell date's rate, so the return includes the currency move.
For exact dates, use the calculator above, which uses trading-day closes where daily data is available; the monthly tables miss the highs and lows inside a month. Figures ignore taxes, fees and the currency effects of non-USD listings.
