Show HN: Realtime 13Fs and track live institutional ownership for any ticker (opens in new tab)

What it does:

- Polls SEC continuously at small intervals

- Fetches all variants of the 13F since the last poll

- Resolves every filing to its effective manager (one filing can contain data for multiple filers or proxy statements)

- Resolves every ticker in each filing to its effective instrument

- Updates the holdings data for the filer (e.g. https://www.signalbloom.ai/13f/filer/point72-asset-managemen...)

- Updates the ticker's 'current view' (re-calculating the aggregate current ownership live) e.g. https://www.signalbloom.ai/13f/ticker/NVDA

- Majority of 13F filers are also registered investment advisers, it links them intelligently (e.g. Blackrock as a 13F filer https://www.signalbloom.ai/13f/filer/blackrock-fund-advisors vs Blackrock as Investment Adviser https://www.signalbloom.ai/investment-adviser/blackrock-fund...)

Reports for: Every single one of over 10k asset managers that files 13F
