Follow the federal money
Why a company's stock can be sensitive to what Congress does: many of them are also paid by the government. Merck & Company, Inc.'s federal contracts, grants and loans are public record.

We link to the source rather than repeat a dollar figure here. Federal awards are recorded under many recipient names — a parent company and its subsidiaries — so an accurate company-wide total has to be read at USASpending itself, where the recipient hierarchy is resolved. Present this beside the trading record and draw your own conclusions.
