Valuesider

valuesider.com

Free web tool for tracking “superinvestor” portfolios and stock ownership changes based on SEC 13F filings. Valuesider notes 13F data is delayed (filed up to 45 days after quarter-end) and incomplete (e.g., shorts not included), and states it only shows data from 2013 Q2 onward due to filing format limitations; shares/prices are split-adjusted. Terms prohibit bots/automated scraping.
