Johnson & Johnson is the world's largest and most diverse healthcare firm. It has two divisions: innovative medicine and medtech. These now represent all of the company's sales following the divestment of the consumer business, Kenvue, in 2023. After restructurings in 2023-24, the drug division focuses on three main therapeutic areas: immunology, oncology, and neurology. Geographically, just over half of total revenue is generated in the United States.

What to Watch
Holds across regimes
Correlation is similar when markets rise (-11%) and fall (+5%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
