01The wedge

By the time it’s news, it’s already priced in.

Every meaningful move in a stock leaves a paper trail before it shows up in a chart. A senator files a transaction. An officer exercises options. A fund discloses a quarter-old position that’s already moved the tape.

Signal sources every filing the moment it hits the SEC, the House, and the Senate. The same disclosures that move billions — surfaced on your phone before the analysts wake up.
