No filing on MDY counts toward a CAT Scan in the last year, so there is no number.
The tape
Daily closes on file for MDY. A disclosed trade plots here as a twin dot, filled at the trade and hollow at the filing.
The cost of chasing
Each rail runs from their trade to their filing. The hatched part is the move a copier missed to the disclosure lag; the solid part is what copying at the filing kept.
Boozman+4.7+2.2
Across 1 priced trade, median copy kept +2.2% from the filing vs +4.7% from the trade date; the lag took 2.5 pts. The S&P returned +13.2% over the same windows. Numbers describe the window shown; they are not a forecast.
Who is behind it
Congress members with a disclosed position, biggest first. Click through to their dossier.
Committee overlap is a fact, not an accusation. An option leg behind a share buy reads very differently from a plain purchase, so it is called out but never scored as intent.
The boardroom
Form 4 insider transactions. The stated plan is part of the record.
No Form 4 insider activity on file for this ticker.
The forward book
Every disclosed option leg on this ticker: what was filed, and where the strike sits versus today.
No disclosed option legs on MDY yet. They plot here the day they file.
A call and a put are shown as filed. We do not infer whether a leg is a hedge or a leveraged bet, because the filing does not say. Read the strike and expiry, not an implied intent.
The fund book
Tracked 13F holders and how their position moved, quarter over quarter.
Positions as filed for the quarter ending 30 Jun 2026, the latest on file. A 13F is a quarter-end photograph filed up to 45 days later, so this is where these funds stood then, not what they hold now. Common stock only: options and short positions are not in a 13F, and a fund that had already sold out does not appear.
Cross-check
When different sources file on the same name inside a window. Overlap like this is rare.
No convergence: MDY is not showing congress and insider filings together in the last 90 days.
Sources file on different clocks; an overlap like this is rare.
