Field notes
Discovery cards pair each reported position with its manager, reported value, weight within the reported share portfolio, and links to Q1/Q2 filings and position history. Some cards add a comparison against the manager’s prior newly reported positions across eight comparable quarters; the page also exposes separate counts for new positions, increases, reductions, and value/share changes. The site labels the newest reporting quarter.
