In depth comparison

Letters and Reviews

lettersandreviews.blogspot.com

Free, personal curation site that aggregates **fund manager letters**, tickers mentioned in those letters, and **quarterly 13F** filer lists the author follows. Each quarter page links to original letters and maps tickers to quick‑reference pages; some 13F pages embed holdings tables and activity (new/increased/decreased/sold) for many managers. Also includes a small **Podcasts** list. No accounts, alerts, exports, or API-think link‑hub for primary sources rather than a data platform.

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.
