Doris O. Matsui Congressional Trading Disclosures | Quantellect Doris O. Matsui Congressional Trading Disclosures

Doris O. Matsui's disclosure record is unusual for what it is not. Of the 50 transactions logged against her name since 2017, only one is attributed to her personally: a sale of Westmed Holding Company in June 2017, reported in the $1,001 to $15,000 range. The other 49 are attributed to her spouse. Investors reading this record should treat it as a household disclosure history built almost entirely from spouse-attributed transactions, not as evidence that the congresswoman personally executed those trades.

The most recent activity reinforces that pattern. On December 15, 2025, four separate purchases of U.S. Treasury Notes, with maturities spread from February 2029 to August 2030, were attributed to her spouse in a periodic transaction report filed January 9, 2026. The fact packet does not supply an amount range for any of the four. There is no sale activity, no equity name, and no non-Treasury instrument anywhere in the 2025 transaction data. That has been the dominant shape of this record for several years running.

A Filing Record Dominated by Treasury Notes, With a Few Exceptions

The year-by-year count shows where the activity actually concentrates. 2023 and 2024 were the two busiest years on record, with 15 and 14 transactions respectively, and every one of the 14 in 2024 was a purchase. 2023 mixed 13 purchases with 2 sales. By contrast, 2022 shows a single transaction, and the record contains no entries at all for 2018 or 2019. The most active recent stretch, then, sits squarely in 2023 to 2025, following two years with relatively few entries.

Most of this volume is Treasury paper. The transaction list is dense with U.S. Treasury Notes across a rolling set of maturities and includes purchases, sales and a partial sale. That pattern is visible across transactions reported for 2020, 2021, 2023, 2024 and 2025, including six separate Treasury Note purchases made on April 23, 2024, and disclosed in a May 2024 filing. Another cluster of nine Treasury Note transactions, eight purchases and one partial sale, was reported in the November 2023 filing. The data classifies 49 of the 50 disclosed transactions under an “Unknown” sector; Nu Holdings is the sole transaction classified under Financials.

The exceptions are where the record gets more interesting. Transactions dated in 2020 include a sale of Zoom Video Communications and a sale of Tencent Music Entertainment's ADR, both amid heavier activity that year across seven sales and five purchases. In June 2021, a purchase of Nu Holdings Ltd (ticker NU) in a disclosed range of $500,001 to $1,000,000 was reported. It is the only NU transaction in the record, and the database includes it in its most frequently disclosed securities field with one transaction. The disclosure classifies Nu Holdings under Financials, in the Banks industry.

The other recurring name is Intrinsic Exchange Group, which appears three times across three different filings: a purchase of an Intrinsic Exchange Group convertible promissory note in June 2022, a purchase of a note receivable from the company in October 2023, and a purchase listed simply as Intrinsic Exchange Group, Inc. in May 2024. All three transactions are attributed to Matsui's spouse. The fact packet supplies neither an amount range nor a company description for any of the three.

Attribution and What the Record Does Not Show

Every transaction in this history carries an attribution code, and the split matters. Forty-nine of fifty are labeled “Spouse,” meaning the transactions are reported as spouse-attributed rather than as transactions attributed directly to Doris Matsui. The single “Self” entry is the oldest one in the record: the 2017 Westmed Holding Company sale, disclosed in the smallest reporting bracket of $1,001 to $15,000. Readers should not treat the volume of Treasury and named-security activity here as evidence that the congresswoman personally executed each transaction.

No Quantellect Score is published for Matsui at the latest score date. In Quantellect's population snapshot dated August 22, 2026, the database lists 537 sitting members of Congress, including 437 House members and 100 senators. Of those sitting members, 276, 237 in the House and 39 in the Senate, have no disclosed trades. At the latest published score date of August 21, 2026, 76 members have a score, including 73 sitting members; no score row exists for Matsui. The data does not state why she lacks a score row, so the absence should not be read as an assessment of her disclosed activity.

Disclosure and Methodology Notes

This profile is built from official periodic transaction reports filed under the Stop Trading on Congressional Knowledge Act of 2012, following the reporting framework described in the House Committee on Ethics financial disclosure instruction guide. Where supplied by the fact packet, disclosed amounts reflect reporting ranges rather than exact transaction values. Dates described as transaction dates are distinct from disclosure dates; under House timing rules, periodic transaction reports generally must be filed within 30 days of awareness and no later than 45 days after the transaction. This page is limited to transaction-level disclosures.
