A real but noisy link — useful as context, risky as a standalone signal.
In 1984, Danaher's founders transformed a real estate organization into an industrial-focused manufacturing company. Then, through a series of mergers, acquisitions, and divestitures, Danaher now focuses primarily on manufacturing scientific instruments and consumables in the life sciences and diagnostic industries after the late 2023 divestiture of its environmental and applied solutions group, Veralto.

What to Watch
Tighter in drawdowns
Pair moves more tightly when both fall (+32%) than when both rise (+3%) — typical risk-off behaviour.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.

Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.
