CapitolRadar analysis
26 trades split evenly between buys and sells
WST has 26 tracked congressional trades from March 29, 2021 through February 13, 2025: 13 buys and 13 sells across three distinct traders. The even transaction count does not establish an even dollar balance because no transaction-value ranges are provided here. It is also a small sample, especially when divided among individual traders and quarters.
The recent quarterly record is sparse. The first quarter of 2025 contains one trade and no buys, while the fourth quarter of 2024 also contains one trade and no buys. The third quarter of 2024 had two trades, including one buy, and the first quarter had two trades, also including one buy. No 2024 second-quarter figure is included in the supplied data.
10 of 13 buys came from Ro Khanna
Ro Khanna accounted for 10 tracked WST purchases, with the latest dated September 9, 2024. Jared Moskowitz recorded two buys, most recently on December 28, 2023. Tommy Tuberville recorded one buy, dated March 29, 2021. Those totals account for all 13 purchases, but only three buyers are represented, limiting the breadth of any pattern.
In the supplied quarterly detail, 2023 had three trades in the fourth quarter with one buy, one trade in the third quarter with one buy, two trades in the second quarter with one buy, and two trades in the first quarter with two buys. That is eight trades and five buys across the listed 2023 quarters.
Six other tickers overlap across two buyers each
Two of the WST buyers also bought each of HD, TJX, PANW, AVGO, MCD and AXP. These overlaps show shared activity in other securities, but the small group of three WST buyers does not support broader conclusions about sector preference or coordinated behavior.
Congressional disclosures can be filed up to 45 days after a transaction, so the public record may lag the trade date. Reported transaction amounts, when available, are disclosed as ranges and any derived dollar values are estimates; no amount ranges are included in these facts.

CapitolRadar signal history
NEW PICK 2026-09-15
Annette F. Favorite, West Pharmaceutical Services’ chief human resources officer, disclosed buying about $224,100 of WST stock, while another company insider also bought shares recently. The panel passed mainly because Favorite has no verified trading history against the S&P 500, so the purchase signal remains unproven. A documented record of her past open-market buys consistently outperforming the market would have strengthened the case enough to change the verdict.
NEW PICK 2026-09-10
West Pharmaceutical President and CEO Michel Lagarde disclosed buying about $4.69 million of WST stock. The panel found the large insider purchase notable, but it fell short mainly because Lagarde has no verified trading history against SPY, leaving the signal unproven. A documented record of his prior purchases outperforming SPY would have strengthened the case enough to change the verdict.
