Katherine M. Clark Stock Trades

The single fact that jumps out of Katherine M. Clark's disclosure record is how lopsided it is in time. The annual counts show that the overwhelming share of the 786 transactions logged under her name since 2014 occurred between 2014 and 2021. Since 2022 the pace has collapsed to single digits each year: seven transactions in 2022, four in 2023, six in 2024, six in 2025, and eight so far in 2026. What's traded in that quieter stretch has also changed character. Much of the disclosed activity since 2022 involves U.S. Treasury notes, alongside a smaller number of individual-stock trades and other securities.

The most recent filing, covering a transaction date of June 16, 2026 and disclosed July 14, 2026, lists eight separate purchases, all attributed to Clark personally (Self), all U.S. Treasury notes maturing between October 2027 and February 2028, in amount ranges of $15,001-$50,000 or $50,001-$100,000 per line. The filing spreads the purchases across notes due in October and December 2027 and January and February 2028, rather than a single maturity. See the filing. The prior disclosure shows a different concentration: four Treasury-note purchases dated October 27, 2025 and disclosed November 6, 2025, all involving the same series due November 15, 2026. Three were attributed to Clark and one to her spouse, in ranges of $100,001-$250,000 or $250,001-$500,000. See the filing.

Trading Activity That Went Quiet After 2021

The busiest year on record by a wide margin is 2014, with 247 transactions, followed by a run of 47 to 63 transactions annually through 2019, a spike to 159 in 2020, and 83 in 2021. Then the volume falls off a cliff: seven in 2022 and never more than eight in any year since. Attribution across the full disclosure record splits almost evenly between Clark personally (382 transactions, coded Self) and her spouse (400 transactions, coded SP), with three joint transactions and one transaction that carries no attribution code in the record and cannot be assigned to any individual.

The clearest single event in the data is a large batch of sale transactions dated September 16, 2021, all coded to Clark's spouse and disclosed October 14, 2021. The list spans a wide cross-section of large, well-known names, including Microsoft, Visa, Mastercard, Alphabet, Home Depot, Starbucks, Honeywell, Merck, Novo Nordisk, Intel, Taiwan Semiconductor, Cisco, S&P Global, State Street, PepsiCo, Best Buy, SAP, Simon Property Group, UBS, and several others. See the filing. A related filing covers a mix of purchases and sales dated July 27, 2021 and disclosed August 15, 2021, many in the same names and also coded to the spouse. See the filing. Taken together, these two filings account for a large share of 2021's 83 transactions and mark the last point at which spouse-attributed activity shows meaningful turnover in individual equities. Nothing in the record after that date matches this scale or breadth.

A handful of transactions since then stand out for reasons other than size. On March 1, 2024, two sales of New York Community Bancorp common stock were disclosed, both coded to Clark personally, in the $1,001-$15,000 range and filed April 4, 2024. See the filing. On January 31, 2024, a partial sale of an interest listed as Ruane, Cunniff & Goldfarb Inc. [PS] was disclosed in the $100,001-$250,000 range; the record supplies no ticker for the transaction. See the filing. And two exchanges of Warner Bros. Discovery shares dated April 8, 2022 were not disclosed until June 8, 2023; both entries are recorded as exchanges rather than purchases or sales. See the filing.

What Shows Up Most Often in the Record

Ranked by how often they appear across the full disclosure history, the most frequently disclosed names include Apple, Home Depot, and Starbucks (12 transactions each), Simon Property Group (11), Intel (10), Merck (9), Amgen, BlackRock, and Microsoft (8 each), and a longer tail including Coca-Cola European Partners, Honeywell, JPMorgan Chase, KLA, Kimberly-Clark, Novo Nordisk, Taiwan Semiconductor, and Visa (5 to 7 each). Nearly all of these show a latest transaction date of 2021 or earlier, which lines up with the broader pattern: this is a record of what was traded repeatedly over more than a decade, not a list of what is currently being bought.

Sector activity across all 786 transactions is led by an "Unknown" category (286 transactions, including government and corporate bonds with no equity sector classification in the record), followed by Information Technology (85), Financials (68), Health Care (66), Industrials (62), Consumer Discretionary (52), Consumer Staples (45), Energy (32), Real Estate (31), Materials (25), Communication Services (19), and Utilities (15). Two tickers in the frequency list, NT and APC, appear repeatedly (11 and 6 transactions respectively) but carry no company name or sector in the record and are identified here only by ticker.

The post-2021 record leans toward U.S. Treasury notes and other debt securities rather than individual company stocks. Treasury-note purchases recur from 2022 through 2026, while a Federal Farm Credit Banks bond was bought in February 2023 and corporate notes issued by NetApp and KB Home were sold in 2022. Individual-stock entries remain, including Coca-Cola, New York Community Bancorp, and Procter & Gamble. See the Federal Farm Credit Banks filing.
