All 30 stock research sites, in one ranking
This is a ranking of attention, not of quality. It says nothing about accuracy, price or features, and it is not investment advice. Three measures, each turned into a rank among the 30 sites (first = 100 points, last = 0, ties share) and then averaged into the index: linking subnets — the number of distinct networks hosting pages that link to the site's domain, from the Majestic Million (2026-10-13), licensed CC BY 3.0; Wikipedia views — human readers of the site's article across every language edition, 2026-09-12 to 2026-10-11, from the Wikimedia pageviews API; Hacker News — stories and comments containing the domain in the 365 days to 2026-10-13, counted with the Algolia HN Search API. 18 of the 30 sites have no Wikipedia article in any language and tie for last on that measure. Sites that live under a larger domain (Yahoo Finance, Google Finance) are left out because their links cannot be separated from the parent's.
