Common ownership of competing firms suppresses competition and inflates prices
Evidence
When large asset managers such as BlackRock and Vanguard hold large blocks of corporate equity of competing firms with the same industries. Common ownership consolidates corporate shares within the hands of a few large firms, which harms competition, incentivizes companies to keep prices high and wages low, and produces conflicts of interest. Also known as horizontal shareholding. — Andrew deWaard, Derivative Media, 484

- DEEPTHINKING: The claim that passive index funds — the socially benign-sounding way retail investors own the market — structurally suppress competition is a genuinely counterintuitive mechanism worth sitting with.

- DEFINE: Defines ‘common ownership/horizontal shareholding’ — a central instrument for the reader’s finance-to-form trace.
