Merck makes pharmaceutical products to treat several conditions in a number of therapeutic areas, including cardiometabolic disease, cancer, and infections. Within cancer, the firm's immuno-oncology platform, led by Keytruda, is a major contributor to overall sales. The company also has a substantial vaccine business aimed at preventing pediatric diseases, as well as Gardasil for human papillomavirus. Additionally, Merck sells animal health-related drugs. From a geographical perspective, 47% of the company's sales are generated from US human health (pharmaceuticals and vaccines).

What to Watch
Holds across regimes
Correlation is similar when markets rise (+14%) and fall (+12%) — 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.
