The record on $RIO

Coldpine has parsed 5 disclosed trades in $RIO by 3 members of Congress, drawn from 5 periodic transaction reports dated Feb 10, 2023 through Jul 10, 2026. That is 4 trades from House members and 1 trade from senators, filed 4 by Democrats and 1 by Republicans.

Of the 5 trades with a known filing lag, 1 was reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 28 days. The longest was 113 days: a $RIO purchase by Alan Armstrong dated Mar 30, 2026, disclosed Jul 21, 2026. How late filing is measured across all of Congress is in the late-filers study.

3 of the 4 trades that list an account holder (75%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $RIO purchases (2), and Gilbert Cisneros the most sales (1).

Activity peaked in 2026 with 2 trades.
