Susan M. Collins Stock Trades

The most striking pattern in Susan M. Collins's disclosure record is not any single trade but the transformation in what gets disclosed at all. Between 2012 and 2018, disclosures tied to the Maine senator's household ran through a diversified range of individual-stock transactions, spiking to 271 transactions in 2014 and 258 in 2013. Beginning in 2019, bond disclosures became much more prominent, and after 2022 individual-stock activity nearly disappeared. In 2026 alone, all three disclosed purchases so far are bonds: a Cumberland County, Maine issue, a Pfizer corporate note, and a Maine State Health & Higher Educational Facilities Authority bond. There is no equity purchase in the most recent disclosures at all.

Across the full record, the database shows 794 disclosed transactions dating back to February 2012, split between 386 purchases, 401 sales, and 7 other transaction types such as exchanges. The overwhelming majority, 619 of 794, are attributed to a spouse rather than to Collins personally; only 65 are attributed directly to her, one to a dependent child, and 109 carry no attribution the data can confirm. That imbalance matters for how a reader should interpret the record: this is predominantly a spousal transaction history contained in Collins's financial disclosures, not a personal trading log.

From Diversified Equities to Fixed Income

The trading pattern breaks cleanly into two eras. The first, running roughly from 2012 through 2018, was heavy in large-cap names across technology, financials, industrials, and consumer sectors. The most frequently disclosed securities over the full history include Microsoft (12 transactions, last disclosed in 2014), Goldman Sachs (10, last in 2014), Meta Platforms under the META ticker (10, last in 2018), Citigroup (9), Apple (8), General Motors (8), and American Express (7), among others. The former FB ticker is separately listed with 8 transactions. Sector activity data reinforces this: Financials (77 transactions), Information Technology (70), and Industrials (65) are the three largest categorized sectors across the full record, followed by Consumer Discretionary (47), Health Care (43), Communication Services (29), and Energy (25).

The single largest sector bucket, however, is "Unknown" at 377 transactions, more than any named sector. That reflects in part the fixed-income securities that increasingly dominate the recent record. In the recent data, municipal bonds and corporate notes are disclosed by issuer and CUSIP rather than by ticker, and the data does not carry a sector classification for them. As disclosed activity shifted toward bonds, transactions with no assigned sector became increasingly prominent.

A notable inflection point falls on January 6, 2022, when spouse-attributed disclosures recorded nine transactions in a single day: purchases of Nvidia, Linde, and Amazon.com, alongside full sales of Carrier Global, Henry Schein, 3M, V.F. Corporation, WEX, and Otis Worldwide. Nvidia designs data-center and AI computing hardware alongside its long-standing gaming graphics business; Amazon operates retail, cloud computing through AWS, and advertising; Linde is an industrial gas supplier serving healthcare, chemicals, and manufacturing customers globally. Two weeks later, on January 21, spouse-attributed disclosures recorded a purchase of Hershey alongside a full sale of Unilever. That cluster is the last broad group of equity purchases and sales visible in the record; after early 2022, disclosed purchases turn almost exclusively to bonds.

A later equity transaction came on December 20, 2022, with a spouse-attributed full sale of Akamai Technologies. Another followed on August 5, 2024, when a spouse-attributed disclosure recorded a full sale of Globe Life, the McKinney, Texas-based life and supplemental health insurer, on the same day as a municipal bond purchase. After that date, every disclosed transaction in the record, including the three from early 2026, has been a bond. Across the 2024 through 2026 bond disclosures, the names include Maine municipal and state authority issues alongside corporate notes from Pfizer, Wells Fargo, Thermo Fisher Scientific, and Fidelity National Information Services.

What the Recent Filings Show

Reading the record since 2022, the picture is one of disclosed activity shifting away from individual stocks and toward fixed income. The January 2022 sales cluster covered industrial, consumer-discretionary, and health-care names, while the same-day purchases were Nvidia, Amazon.com, and Linde. Within weeks, the purchase disclosures shifted to corporate and municipal bonds. Across the broader fixed-income record, disclosed purchases include Maine municipal issuers such as Portland, Scarborough, Waterville, and York, alongside national corporate debt. Disclosure lag varies by filing: the transaction dated September 19, 2019, for instance, was not disclosed until May 7, 2020, illustrating that a disclosure date does not always track closely with the underlying transaction date.

Overall, the record does not show frequent trading in the most recent period. 2024 carried six disclosed transactions, 2025 carried one, and 2026 has carried three so far, a marked slowdown from the multi-hundred-transaction years of 2013 and 2014. The 109 transactions with unknown attribution and the near-total absence of individual-stock activity after 2022 make this a household disclosure record now oriented toward fixed income rather than equity selection.
