Frequently Asked Questions

Which SEC filings does Fin45 prioritize?

13D filings (activist stakes above 5%) and 8-K filings (material events like acquisitions, leadership changes, or guidance updates) receive the highest priority scores.

How are 13F filings used?

13F filings reveal institutional portfolio changes quarterly. Fin45 identifies when multiple top-performing funds simultaneously increase positions in the same stock.

Does Fin45 analyze filing text?

Yes. Natural language processing extracts sentiment, key terms, and material changes from filing text, especially 8-K and proxy statement narratives.
