CapitolRadar analysis
45 tracked ALGN trades split 19 buys and 26 sells
Align Technology, Inc. (ALGN), a Healthcare / Medical - Devices company, had 45 tracked congressional trades from 2020-11-06 through 2026-09-11. The activity comprised 19 buys and 26 sells by four distinct traders, giving sells a seven-trade lead. With only four participants, this is a small sample and may reflect the activity of a few individuals rather than a broad congressional pattern.
The listed buyers account for all 19 tracked buys. Ro Khanna recorded 12, with the last on 2024-09-09. Josh Gottheimer recorded five, most recently on 2023-03-06. Diana Harshbarger and Tommy Tuberville each recorded one, last dated 2022-09-26 and 2021-03-29, respectively. Khanna alone represented more than half of the recorded purchases, underscoring the concentration within this limited group.
3 recent 2026 trades contained no buys
The provided quarterly data show two trades and zero buys in 2026 Q3, plus one trade and zero buys in 2026 Q1. Earlier activity was mixed: 2024 Q3 had one trade, which was a buy; 2024 Q2 had one trade and no buys; and 2024 Q1 had two trades, both buys.
In 2023, Q2 recorded four trades with two buys, Q3 recorded two trades with one buy, and Q4 recorded three trades with one buy. These quarter-level observations are also small samples, so shifts in buy/sell balance should not be treated as durable trends.
6 other tickers overlapped across two ALGN buyers
Two of the ALGN buyers also purchased each of ADI, RSG, GOOGL, SNDK, AMD and MSFT. The facts do not identify whether the same pair accounts for every overlap or provide timing for those purchases, limiting comparisons.
Congressional disclosures can appear up to 45 days after a transaction, so the record is not real time. Any disclosed dollar amount ranges are estimates rather than exact transaction values; no amount ranges are provided here.
