Applied Materials is the largest semiconductor wafer fabrication equipment manufacturer in the world. It has a broad portfolio spanning nearly every corner of the WFE ecosystem. Applied Materials holds leading market share in deposition, which entails the layering of new materials on semiconductor wafers. It is more exposed to general-purpose logic chips made at integrated device manufacturers and foundries. It counts the largest chipmakers in the world as customers, including TSMC, Intel, and Samsung.

What to Watch
Holds across regimes
Correlation is similar when markets rise (-16%) and fall (-31%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
Time Series
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.

Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
