Common questions about ARM
Which members of Congress have traded ARM?
2 distinct members appear in the disclosures for Arm Holdings plc, across 4 transactions, 2 of them purchases. The table above names each one with their chamber, the trade date and the date it was disclosed.
Why is there a gap between the trade date and the disclosure date on ARM?
The STOCK Act gives members up to 45 days to file. The most recent ARM entry here was traded 2025-12-11 and disclosed 2025-12-17. That lag is the law working as written, not evidence of anything, and it is the main reason this data is context rather than a signal.
Why are the amounts shown as ranges?
Because that is how they are filed. Members report a bracket, such as $1,001 to $15,000, never an exact figure. Anyone quoting a precise dollar amount for a congressional trade is estimating from the bracket.
Does following congressional trades work?
The results are mixed and the delay is the reason. By the time a ARM trade is public it can be six weeks old. What the data is genuinely good for is noticing when several members converge on the same name in the same window, which is visible in the table above and rare enough to be worth a look.
How many of the ARM congressional trades were purchases?
2 of 4 in the disclosures shown here.
When was the most recent congressional trade in ARM?
The latest filing on this page shows a trade dated 2025-12-11, disclosed on 2025-12-17. New filings arrive as members file, so the page can change any day.
Where do the ARM congressional trade records come from?
From the periodic transaction reports members of the House must file under the STOCK Act, published by the Clerk of the House. Each row on this page is one line of one filing, with the chamber, the trade date and the disclosure date kept as filed.
Can I see which committee a member trading ARM sits on?
Not on this page. Committee assignments are public on the House and Senate sites, and they are the context that makes a trade interesting or not: a purchase in a name the member's committee oversees reads differently from a purchase in an index fund. That check is worth doing by hand for the few names that matter.
