How Far Do You Have to Slide Before the "Match" Appears?
Drag the slider to translate the 1995–2000 dot-com window left or right against 2020–2025. The correlation panel is the lookup of bar-by-bar Pearson r at every possible shift.

Methodology · Pearson r is computed on the overlapping window only (smaller overlap at extreme lags). Lag is measured in trading days; positive lag = 1995–2000 window slid right (later) relative to 2020–2025. The "Instagram-style" preset (≈ −590 bars / −2.3 yrs) approximately reproduces the framing in the viral chart, which starts the dot-com series around 2022–2023 instead of 2020. Returns r is computed on log-returns, which is what bar-by-bar similarity actually requires.
