More product searches start on Amazon than on Google. That single fact makes Amazon search data one of the most direct behavioral signals available for consumer, retail, and e-commerce investing. When a consumer searches for a brand or product on Amazon, they are describing purchase intent at the point of decision -- not passive curiosity, not early-stage research, but active intent to buy.
For institutional investors and hedge funds, that translates into a measurable, high-frequency leading indicator that moves weeks or quarters ahead of reported earnings.
