Why 13F filings matter
Funds managing over $100M in U.S. equities must publicly disclose their long positions every 90 days. By itself a 13F doesn't tell you when a fund bought or sold, only what they held at quarter-end. But cross-fund overlap on small-cap and pre-pop names often surfaces the same setup we look for in our research.
