Methodology
The figures on this page use VST's historical price data from 2017-05 to 2026-10. The tables and the calculator above use month-end closes.
Prices come from IEX Historical 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.
Prices are the last regular-session trade on IEX (Investors Exchange) each day, which can differ slightly from the official close. Month-end closes miss the highs and lows inside a month. Figures ignore taxes, fees and the currency effects of non-USD listings.
