Darrell Issa Trading Activity | Quantellect Darrell Issa Trading Activity

Every one of Darrell Issa's disclosed transactions since 2023 has been a sale, not a single purchase among them. Twenty transactions, zero buys. That one-way pattern is the defining fact of his disclosure record.

Issa, the Republican representing California's 48th District, has filed disclosures covering 20 transactions between February 9, 2023 and April 10, 2025. All 20 are attributed to Issa himself (attribution code SELF), all 20 are sales, and none are purchases. The activity is heavily concentrated in short-term U.S. Treasury Bills, along with one large interest rate cap transaction disclosed in April 2025.

A Treasury-heavy liquidation pattern

The bulk of the disclosed activity, 19 of the 20 transactions, involves sales of U.S. Treasury Bills identified by CUSIP number, each with a stated maturity date. These instruments carry due dates ranging from April 6, 2023 through August 15, 2024, with transaction dates including February 9, February 23, March 10, March 15, and May 2, 2023, followed by a cluster running from January 24 through August 5, 2024. Several of the sales are marked "Sale (Partial)," including five separate partial sales tied to the same underlying instrument, a Treasury Bill with CUSIP 912796YN3 due April 6, 2023, with transaction dates from February 9 through March 24, 2023.

Transaction volume by year, according to the packet's own tally: 7 transactions in 2023, 12 in 2024, and 1 in 2025. All years show sales exclusively, with no purchases or other transaction types recorded in any of the three years.

The amount ranges disclosed for these Treasury Bill sales are large. Most fall in the $5,000,001 to $25,000,000 band, with several in the $1,000,001 to $5,000,000 range. These are congressional disclosure bands, which report a range rather than an exact dollar figure, so the true transaction size within each band is not stated in the underlying data.

The most recent disclosed transaction, dated April 10, 2025 and filed April 17, 2025, stands apart from the Treasury Bill pattern. It is described as an "Interest Rate Cap Transaction UBS," carrying the largest amount range in the entire record: $25,000,001 to $50,000,000. It is the only non-Treasury transaction in the dataset. The packet supplies no ticker, company name, company description, sector, industry, CUSIP, or maturity date for this row.

What the record does not show

None of the 20 disclosed transactions identify a ticker symbol, company name, sector, or industry. The packet's own sector classification for all 20 rows is "Unknown." This means the disclosures in this dataset are limited to Treasury instruments and one interest rate cap transaction, not corporate equity trades. There is no record here of stock purchases, stock sales, or sector concentration in individual companies.

Quantellect did not publish a Quantellect Score for Darrell Issa at the latest published score date, August 21, 2026, because no score row existed for him on that date. Score records existed for 76 members overall, 73 of whom were among the 537 sitting members of Congress. Separately, 276 sitting members had zero disclosed trades, including 237 of the 437 sitting House members, underscoring how much variation exists across the chamber in disclosure activity, even before scoring is considered.

Disclosure basis and limitations

This profile is built from Darrell Issa's official periodic transaction reports filed with the U.S. House of Representatives. Under the Stop Trading on Congressional Knowledge Act of 2012, covered transactions generally must be reported no later than 30 days after the filer receives notification and in no case later than 45 days after the transaction. The underlying reports can be reviewed directly: the filing covering 2023 transactions, the filing covering 2024 transactions, and the 2025 transaction filing. Filing requirements and disclosure mechanics are further detailed in the House Committee on Ethics financial disclosure instruction guide. Amounts are reported in required ranges rather than exact figures, and disclosure dates can trail transaction dates by weeks or months, as reflected in the gap between several 2023 and 2024 transaction dates and their corresponding 2024 disclosure dates. The dataset supplies transaction disclosures only, and references to "trading activity" describe only the frequency and pattern of those disclosed transactions.
