Compare FAQ
- What does the RGEN vs SPY overlay show?
- LOPJLB overlays RGEN vs SPY as total return (dividends and splits) from the first adjusted close in the selected 5Y window. Each path starts at 0% so you can read relative holding performance, not raw tape price.
- Is this holding return or tape close?
- Holding return. The series uses split- and dividend-adjusted close (Yahoo-style backward adjustment) when dividend coverage is sufficient, otherwise it falls back to tape close. Candles and technical overlays on /chart stay tape.

- Drawdowns are current and worst peak-to-trough on the visible range. Periods are calendar lookbacks (1Y / 2Y / 3Y / 5Y, plus 10Y on MAX) from the last bar. Annual is calendar-year holding return, with the latest year labeled YTD.
