Thirteen Foxtrot

Know exactly what they're holding — straight from the filing, not the blog post.

Tracks one fund's SEC filings quarter by quarter and delivers a clean breakdown of what changed — new stakes, exits, top holdings, and the options positions most sources quietly leave out. Thirteen Foxtrot works from the primary 13F on EDGAR first, falls back on aggregators only when necessary, and always tells you which source you're looking at. No secondhand summaries passed off as filings data.
