FundFlow is StonkWhisper's institutional sentiment index derived from SEC 13F filings. Institutional investment managers with at least $100 million in qualifying assets under management are required to file 13F reports within 45 days of each quarter end, disclosing their long positions in U.S. equities. FundFlow aggregates these disclosures across 170+ tracked managers and produces a net conviction score for each ticker. A rising FundFlow score — especially when driven by new position opens from concentrated funds — is a leading indicator of institutional thesis formation.
