Real-time signals between the quarterly 13Fs — insider buys/sells, new activist stakes, and ARK’s daily ETF trades.
Sources: SEC Form 4 (open-market buys/sells, codes P/S, filed within 2 business days) and Schedule 13D/13G (5%+ stakes), plus ARK Invest daily ETF trades (day-over-day changes in ARKK’s published holdings). Only managers who are insiders or 5%+ owners file with the SEC, so most passive positions still appear only in the quarterly 13F. Material transactions only. Not financial advice.
