Congress Edition

Week of 2026-07-27

This week's 102 disclosed congressional trades were dominated by a single omnibus Senate filing that covered 96 transactions from late March 2026 — all reported months past the legal deadline.

The Big Picture

Nearly all of this week's activity came from one filing. Sen. Alan Armstrong (R-OK) disclosed 96 trades at once, all executed in late March 2026 but reported 113 to 116 days after the fact, well past the 45-day STOCK Act window. The remaining six trades came from three other members and were filed on time. Buying was broadly diversified, with financial services and industrials leading the way, while selling was relatively light.

Late to File

Under the STOCK Act, members must disclose a trade within 45 days. This week, every late filing belongs to one member. Sen. Alan Armstrong (R-OK) reported all 96 of his March 2026 trades in a single disclosure on July 21 — between 113 and 116 days after the trade dates, or roughly 70 days past the legal deadline. A sampling: Armstrong — SanDisk Corp (SNDK), 116 days late; Armstrong — PepsiCo Inc (PEP), 116 days late; Armstrong — PayPal Holdings Inc (PYPL), 116 days late; Armstrong — The PNC Financial Services Group Inc (PNC), 116 days late. The filing spans domestic and international stocks across more than a dozen sectors.

All-time: Across 21,793 total disclosures tracked in this dataset, 2,559 — or 11.7% — arrived late. The five members with the most cumulative late filings on record are Rep. Sheri Biggs (171), Rep. Julia Letlow (136), Rep. Valerie Hoyle (114), Sen. Thomas H. Tuberville (105), and Sen. Alan Armstrong (96). Late disclosure is a timing compliance matter; it does not imply any wrongdoing related to the trades themselves.

The Fine Print

Data derived from public STOCK Act disclosures. Disclosure date is not the trade date (filings lag 30-45 days). Dollar figures are disclosed ranges, not exact amounts. Conflict-of-interest flags are heuristic "potential overlaps," not assertions of wrongdoing. Not investment advice.
