The tape
Price with a twin dot per disclosed trade: filled at the trade, hollow at the filing. The dashed gap is what the market did in between, not anyone’s return.

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.

Median copy kept +77.6% from the filing vs +83.6% from the trade date; the lag took 6.0 pts. The S&P returned +16.7% 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
Scheduled 10b5-1 sales are usually noise, set on autopilot months ago. The unscheduled ones are the tell.

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 MKSI 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.
13F fund positions on MKSI light up when fund ingestion lands. Quarter-end marks, up to 45 days lagged, never live holdings.
Cross-check
When different sources file on the same name inside a window. Overlap like this is rare.
No convergence: MKSI is not showing congress and insider filings together in the last 90 days.
Sources file on different clocks; an overlap like this is rare.
⚠️ Public information, sourced from STOCK Act, Form 4 and 13F filings. Ranges use midpoints. Price paths between a trade and its filing are market moves, not anyone’s return. Not financial advice.
