Known limitations

What we don't do — yet.

The honest edges of the model. Every number on this site is nominal — we do not deflate for inflation, so a 2015 dollar and a 2026 dollar are shown at face value. We do not model income, dividend, or capital-gains taxes, and we report no risk-adjusted metrics such as volatility or Sharpe ratio. Treat results as a disciplined backtest, not a forecast.

Assumptions
  • 01All values are nominal — no CPI/inflation deflation or real-dollar mode.
  • 02No income, dividend, or capital-gains tax modeling.
  • 03No risk-adjusted metrics (volatility, standard deviation, Sharpe) are computed.
  • 04No FX or non-USD assets.
  • 05No single-stock options or short positions.
  • 06No leverage beyond a 30-year fixed mortgage.
  • 07No rebalancing or trading-strategy alpha.
