STOCK ACT DISCLOSURE TRACKER
NIO Senator & Congress Trading Activity
Track every disclosed NIO trade by members of the U.S. Senate and House of Representatives, filed under the STOCK Act. Congressional trading has consistently outperformed the S&P 500 in recent years, and elected officials have access to information flows retail investors do not — which is why "follow the politician" is one of the fastest-growing retail strategies.

Why congressional trades of NIO matter
Members of Congress often trade individual stocks like NIO while sitting on committees with jurisdiction over the industry the company operates in. Because these trades are legally disclosed under the STOCK Act — but often buried in raw PDFs on the House and Senate disclosure portals — retail investors rarely see them in time to act. Our NIO congressional tracker parses those disclosures the day they publish, groups them by member, and flags trades where the member sits on a directly-relevant committee.
Combined with insider Form 4 data and technical signals on the interactive dashboard, this gives you a "smart-money view" of NIO that would otherwise cost hundreds of dollars a month on institutional platforms.
Frequently asked questions about NIO congressional trades
Is congressional trading of NIO legal?
Yes. Members of Congress are permitted to trade individual stocks so long as they disclose transactions within 45 days under the STOCK Act (Stop Trading on Congressional Knowledge Act, 2012). Multiple bills to ban the practice are pending but none have passed as of 2026.
How reliable is congressional trading as a signal for NIO?
Studies (Ziobrowski 2004, Belmont 2020) have found sitting members of Congress have historically outperformed the market. Individual trades vary — but a cluster of purchases by members on relevant oversight committees has been shown to precede outperformance.
How current is the NIO congressional trade data?
We ingest STOCK Act disclosures within hours of publication on the House and Senate financial disclosure portals. The interactive dashboard shows the most recent 12 months of activity for every ticker with reported trades.
