How the radar works

  1. Detect. New SEC filings are pulled within minutes and matched to their NYSE or Nasdaq tickers: 8-Ks, merger filings (425), tender offers, target responses (14D-9), activist stakes (13D) and share offerings. Deals reported by Bloomberg, CNBC and the FT are read from the headlines and marked unconfirmed until the companies file.
  2. Read. The filing's item codes and text separate a CEO resignation from a routine director election, or a merger from a supply contract. Flags like "effective immediately" or an interim successor raise the severity.
  3. Rank. Severity is weighted by liquidity (average dollar volume) and by the actual price and volume reaction once the market trades it. High-impact events get an AI brief that pulls in news headlines for context.
  4. Alert. If a ticker is on your watchlist, you get a notification (turn on "Watchlist alerts" in Notifications for push).

Educational tool, not investment advice. Filings are summarized automatically and can be misread; always check the filing itself. Prices may be delayed.
