    Is this investment advice?

    No. Wall Street Regrets is an entertainment and education tool. Every number is a historical calculation, not a prediction, and past performance never guarantees future results.

    Methodology

    Ultragenyx Pharmaceutical Inc. (RARE) historical total-return data from 2014-01 to 2026-09, reduced to month-end closes for the tables above.

    Returns use adjusted close prices — adjusted for stock splits and reinvested dividends, the same convention used by major brokerages. End-of-day and live 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 available month-end close. Non-USD amounts are converted at historical month-end exchange rates (EODHD): to USD on the buy date and back to your currency at the latest rate, so the return reflects the currency move as well as the asset.

    Month-end resolution means intra-month extremes are not captured in tables; the calculator uses exact trading-day closes where daily data is available. Figures ignore taxes, fees, and the currency effects of non-USD listings. History is not a forecast. Wall Street Regrets is entertainment, not investment advice.
