Suzan K. DelBene Stock Trades

The most recent disclosures from Representative Suzan K. DelBene of Washington's 1st District read less like a stock trader's ledger and more like a bond desk's activity log. Every transaction dated in 2025 and 2026 in the record concerns a named bond or debt security, purchased or sold in disclosed ranges as large as $500,001 to $1,000,000, and every one of them is attributed jointly rather than to DelBene individually. That is not a new turn so much as the latest chapter of a trading history that has moved decisively away from the single-name technology and industrial equities that defined its earlier years.

Across the full disclosure record, 840 transactions have been logged under DelBene's name since December 23, 2013, the most recent dated July 23, 2026. Of those, 453 were purchases, 386 were sales, and one was logged as another transaction type. Attribution matters here: 779 of the 840 transactions carry the "Joint" code, 60 are attributed to a spouse, and just one is attributed to DelBene directly. None are attributed to a dependent child. In other words, the overwhelming share of this activity is jointly attributed rather than attributed solely to the member of Congress.

From Tech and Industrial Trading to Bond Transactions

The security that appears most often across the full history is Microsoft Corporation, with 62 disclosed transactions (39 purchases and 23 sales), the last of which was dated August 31, 2024. No other name comes close in frequency. Behind Microsoft, the next tier of frequently disclosed names is dominated by industrial and clean-energy-adjacent equipment makers tagged to the Industrials and Information Technology sectors in the data: Complete Solaria, Energy Recovery, Acuity Brands, Flowserve, First Solar, Itron, Johnson Controls, Xylem, Watts Water Technologies, Valmont Industries, MYR Group, Trimble, Cognex, SolarEdge Technologies, and Canadian Solar, among others. A striking number of these securities share the same latest transaction date, June 9, 2016, showing that many of the names saw transaction activity on the same day.

The year-by-year record supports that read. 2014 was the most purchase-heavy year on file, with 113 total transactions split 77 purchases to 36 sales. 2016 flipped that pattern sharply, with 103 transactions split 26 purchases to 77 sales, the largest annual sale count in the dataset. From 2020 through 2024, purchases exceeded sales in every year; the pattern reversed in 2025, which logged 86 transactions, 65 of them sales against 21 purchases, and the 23 transactions recorded so far in 2026 split 8 purchases to 15 sales. Earlier, 2018 logged 29 purchases and 21 sales, while 2019 logged 24 purchases and 11 sales. Taken together, the record moves from purchase-heavy activity in 2014 to sale-heavy activity in 2016, followed by several purchase-leaning years and, most recently, bond transactions with more sales than purchases.

That change also shows up in the sector breakdown. Of the 840 total transactions, 706 carry no assigned equity sector. Of the transactions that do carry a sector tag, 82 fall under Information Technology, 41 under Industrials, 6 under Consumer Discretionary, 2 under Energy, 2 under Real Estate, and 1 under Health Care.

What the Recent Filings Show

The transactions dated in 2025 and 2026 are dominated by general obligation and revenue bonds associated with school districts, transportation authorities, housing finance agencies, municipal utilities, and other issuers across states including Texas, New York, Washington, Maryland, Illinois, Wisconsin, and Alabama. The most recent, a purchase in the $250,001 to $500,000 range of a Fort Bend Texas Independent School District bond dated July 23, 2026, was disclosed August 11, 2026 in an official filing. Earlier that year, a $500,001 to $1,000,000 purchase of the security listed as “Pacific Co B1 Bond - Trimble 05/29/28” was disclosed on June 11, 2026 in a separate official filing.

Two dates stand out for the sheer volume of activity packed into a single filing. On January 13, 2026, thirteen separate partial-sale transactions across bonds associated with jurisdictions and authorities in states including Texas, Illinois, Arizona, and North Dakota were disclosed together on January 23, 2026 in an official filing. A similar cluster occurred on July 16, 2025, when nineteen partial-sale transactions spanning bonds from Honolulu to Colorado to New Jersey were disclosed on August 9, 2025 in another official filing. The record contains repeated same-day, multi-bond batches, but every transaction in these recent batches carries the joint attribution code, and the disclosures do not identify DelBene personally as the underlying decision-maker.

No Quantellect Score is currently available for DelBene. As of the latest published scoring date, August 21, 2026, 76 members have a score row, 73 of whom are among the 537 currently sitting members of Congress; DelBene does not have a score row at that date. For context, 276 of the 537 sitting members, including 237 of 437 House members and 39 of 100 senators, have no disclosed trades on record at all. DelBene's disclosure history contains 840 transactions even without a score attached to it.

About This Disclosure Data

This profile is built from transactions disclosed in periodic transaction reports filed under the Stop Trading on Congressional Knowledge Act of 2012. The law establishes a defined filing window for qualifying transactions by covered filers. Read the STOCK Act. Dollar amounts are disclosed as ranges rather than exact figures, and the "Joint," "Spouse," and "Dependent Child" attribution codes reflect how each transaction was filed, per House Committee on Ethics guidance, not necessarily who made the underlying investment decision.
