Seven stock trades were disclosed by members of Congress between March 28 and April 4, 2026, according to newly filed reports under the STOCK Act. The activity came from just two lawmakers and leaned heavily toward buying: five purchases versus two sales.
Sen. John Fetterman, a Democrat from Pennsylvania, accounted for the majority of the activity with five transactions. Sen. Tina Smith, a Democrat from Minnesota, disclosed the remaining two trades. Together, their filings touched seven different companies across technology, financial services, and industrials.
The disclosures provide another snapshot of how lawmakers and their families are positioning personal portfolios while Congress debates economic policy, technology regulation, and federal spending. Under the 2012 STOCK Act, members of Congress must disclose most securities trades within 45 days.

Fetterman Leads the Week With Five Purchases
Sen. John Fetterman reported five separate stock purchases during the period, making him the most active trader of the week by volume.
His buys included shares of semiconductor maker MU (Micron Technology), software giant MSFT (Microsoft), and insurance services firm ERIE (Erie Indemnity Company). Each appeared once in the week’s filings and represented purchases rather than sales.
The companies span sectors that have been closely tied to broader economic and policy conversations in Washington. Semiconductor manufacturers such as Micron remain central to federal industrial policy after the CHIPS and Science Act directed tens of billions of dollars toward domestic chip production. Microsoft, meanwhile, sits at the heart of debates over artificial intelligence regulation, cloud infrastructure, and federal cybersecurity contracts.
Erie Indemnity represents a different corner of the market: regional insurance services. The company manages the Erie Insurance Exchange and is often viewed as a steady financial-sector play tied to property and casualty insurance performance.
While the disclosure forms do not provide precise share counts, congressional filings typically report transactions in value ranges such as $1,001–$15,000 or $15,001–$50,000.
Tina Smith Reports Two Sales
Sen. Tina Smith disclosed the week’s only sales. Her two transactions involved long-established U.S. companies: MMM (3M Company) and BRKB (Berkshire Hathaway Class B).
Both positions were reported as sales rather than purchases. Berkshire Hathaway, the conglomerate led by Warren Buffett, is one of the most widely held large-cap stocks among institutional and retail investors alike due to its diversified portfolio of operating businesses and equity stakes.
3M, the Minnesota-based industrial manufacturer, has faced several years of legal and restructuring challenges tied to earplug and environmental liabilities. The company has been in the process of reshaping its business and recently spun off its healthcare division, moves closely watched by investors.
Technology and Industrials Appear in the Mix
Despite the small sample size, the week’s trades touched several sectors that frequently appear in congressional portfolios.
- Technology: Purchases of MU and MSFT reflect continued investor interest in semiconductors and software infrastructure.
- Financial and Insurance Services: ERIE represents a more traditional financial-services exposure.
- Industrials and Conglomerates: Sales of MMM and BRKB highlight holdings in diversified legacy companies.
Even during slower reporting weeks, congressional trades can draw attention because lawmakers may have access to policy discussions or economic briefings not available to the public. The STOCK Act prohibits members from trading on nonpublic information gained through their official roles, but it does not ban them from owning or trading individual stocks.
A Quiet Week for Disclosures
Compared with more active periods that can feature dozens of filings, the March 28–April 4 window was relatively quiet. Only two lawmakers reported trades, and the total number of transactions remained in the single digits.
Still, individual filings can provide clues about portfolio shifts or sector preferences among policymakers. Purchases in technology companies such as MSFT and MU stand out given the ongoing legislative focus on artificial intelligence, semiconductor supply chains, and U.S. competitiveness with China.
With the 45‑day reporting window under the STOCK Act, additional trades executed during late March or early April could still appear in future filings. As those disclosures arrive, they will offer a clearer view of how lawmakers were trading during the early spring market environment.
