nsidr - Investor Tracker

nsidr gives you real-time visibility into the trades that matter most — the ones made by people who know their companies better than anyone else.

Corporate Insiders
CEOs, CFOs, board members, and general counsels are required by law to report their personal stock trades. nsidr ingests these SEC filings daily and surfaces the signal — who bought, how much, and why it matters.

Congressional Trading
Members of Congress must disclose stock trades under the STOCK Act. nsidr tracks Senate and House filings so you can see exactly which legislators are trading — and in what.

Follow What Matters
- Follow individual insiders and get notified the moment they file a new trade
- Follow stocks and track every insider move on that ticker
- See trade history, estimated share counts, and filing delays

Inside Track
Every trade comes with context — what role the insider holds, how the trade compares to their salary, and whether they sit on a committee that regulates the industry they're buying into.

Built for Clarity
- Clean, dark interface designed for fast scanning
- Buy/sell color coding with party and chamber identifiers for congressional trades
- Full transaction detail with historical trades on the same ticker

nsidr doesn't give financial advice. It gives you the same information that's publicly filed — organized so you can actually use it.
