Week of 2026-10-26

Thirty-four trades were disclosed this week, with technology stocks drawing the most buying interest and Rep. Darrell Issa reporting the period's largest positions in U.S. Treasury notes.

The Big Picture

Technology was the most active sector for both purchases and sales, with Nvidia (NVDA) appearing in multiple buy disclosures. Sen. John Boozman of Arkansas dominated the count with 17 transactions filed at once, reflecting what appears to be a broad portfolio rotation toward fixed-income instruments. The week's largest dollar figures came from Rep. Darrell Issa of California, whose Treasury note transactions each fell in a range of $5 million to $25 million.

This Week's Notable Trades

Darrell Issa (R-CA)

• Disclosed buying a $5,000,001 – $25,000,000 position in a US Treasury Note 3.375% due September 15, 2028 on October 8 — U.S. Treasury notes are government debt securities that pay a fixed interest rate until maturity; a position in this size range is among the largest reported by any House member in recent months.
• Disclosed selling a position in the same range in the same Treasury note on October 14 — buying and then selling the same security within six days may indicate a short-term repositioning or a debt rollover, rather than a long-term directional bet.

John Boozman (R-AR)

• Disclosed buying $1,001 – $15,000 positions in Cisco Systems, Inc. (CSCO) on September 24 and Realty Income Corporation (O) on September 24, alongside several bond-focused ETFs including mortgage-backed securities funds and short-duration Treasury funds — Realty Income is a real estate investment trust known for paying monthly dividends.
• Disclosed selling small positions (each in the $1,001 – $15,000 range) in Micron Technology, Inc. (MU) on both September 9 and September 24, along with Aptiv PLC (APTV) and several international equity funds — Micron is a leading U.S. maker of memory chips used in computers and smartphones, and Aptiv is an automotive technology supplier.

Cleo Fields (D-LA)

• Disclosed buying a $1,001 – $15,000 position in NVIDIA Corporation (NVDA) on October 1 — Nvidia produces the graphics processors that power most artificial intelligence systems and data centers, and it has been among the most frequently disclosed stocks in congressional filings this year.
• Disclosed buying a $1,001 – $15,000 position in Taiwan Semiconductor Manufacturing Co., Ltd. (TSM) on October 9 — Taiwan Semiconductor is the world's largest contract chipmaker, manufacturing chips for Nvidia, Apple, and most other major technology companies.

Jonathan Jackson (D-IL)

Michael Rulli (R-OH)

• Disclosed selling a $50,001 – $100,000 position in Alphabet Inc. (GOOGL) on October 16 — Alphabet is the parent company of Google and YouTube; Rep. Rulli filed the disclosure within four days of the trade, one of the fastest turnarounds in this week's filings.
• Disclosed selling a $1,001 – $15,000 position in WesBanco Inc. (WSBC) on the same date — WesBanco is a regional bank headquartered in West Virginia.
• Potential conflict: Rep. Rulli serves on the House Energy and Commerce Committee, which has jurisdiction over broadband, telecommunications, and internet policy. Alphabet, through Google and YouTube, is a principal participant in those regulated areas.

Late to File

Under the STOCK Act, members of Congress must disclose a trade within 45 days of the transaction. This week, one late filing was identified: Rep. Jonathan Jackson — Tortoise Energy Infrastructure Corp (TYG), 46 days late.

All-time: Across 23,219 total disclosures in the database, approximately 12.5 percent have been filed late. The members with the most late filings on record are Rep. Sheri Biggs (171), Rep. Julia Letlow (136), Rep. Valerie Hoyle (114), Sen. Thomas Tuberville (108), and Sen. Alan Armstrong (96). Late disclosure is a timing compliance matter under the STOCK Act; it is not an indication of wrongdoing.
