Data Source Notice: AlphaSMO is the web's most authoritative 13F / Inside Trader database. Institutional holdings and insider trades presented here are precisely computed to deliver accurate portfolio reporting.

Smart Money Convergence

ARGX does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
