John J. McGuire III Stock Trades

John J. McGuire III: Congressional Trading Disclosure Profile

Every one of the twenty transactions disclosed under Rep. John J. McGuire III's name since he took office is attributed to his spouse. None are marked as the congressman's own account, and none are joint or dependent-child transactions. That single fact should frame how a reader interprets everything that follows: this is a record of spousal trading activity disclosed under the Virginia Republican's reporting obligation, not a documented account of decisions he personally made.

McGuire represents Virginia's 5th District and began his current term on January 3, 2025. The disclosure history opens shortly after, with a purchase dated April 10, 2025, and runs through the most recent disclosed transaction dated July 31, 2026. Across that span the record shows 20 total transactions: 12 purchases and 8 sales, with no transactions of any other type recorded. Activity was not evenly distributed. The 2025 calendar year shows 5 transactions (4 purchases, 1 sale), while 2026 shows 15 (8 purchases, 7 sales). Both years are represented in the same underlying dataset, so the comparison itself is on solid footing even without translating it into a rate.

A Technology-Heavy, Spouse-Attributed Trading Pattern

Sector activity is concentrated. Of the transactions with a sector on file, Information Technology accounts for 11, Communication Services and Financials each account for 3, and Consumer Staples and Health Care each account for 1. One additional transaction, the SpaceX-linked security described below, carries no sector classification in the data. The most frequently disclosed names span two sectors: Microsoft, classified as Information Technology, shows up three times (two purchases, one sale), while BlackRock, classified as Financials, also shows up three times, all as sales.

The BlackRock activity is worth isolating because of its shape. The disclosures show a partial sale on July 7, 2026, a second partial sale on July 10, 2026, and a full sale on July 14, 2026, across two filings. Rather than a single disposition, the record shows three separate disclosed sales over roughly a week. Microsoft shows a separate buy-sell-buy sequence: a purchase on January 21, 2026 was followed nine days later by a partial sale, with another purchase disclosed on April 15, 2026. Nvidia was purchased on January 30 and April 15, with the latter date also including a first disclosed purchase of Apple. Meta Platforms appears twice, both as purchases, in June 2025 and June 2026. ServiceNow appears twice as well, first as a purchase in May 2025 and then as a partial sale in June 2025.

The most recent disclosures, covering trades from mid-June through the end of July 2026, include the SpaceX-linked purchase described below, a purchase of Applied Materials, a partial sale of Palo Alto Networks, and the BlackRock sales described above. Applied Materials supplies semiconductor manufacturing equipment used across the chip industry, spanning etch, deposition, and wafer inspection tools. Palo Alto Networks sells cybersecurity software and platforms, including its Cortex security-operations suite and cloud-native protection tools. Both are categorized under Information Technology, reinforcing the sector's dominance in this disclosure record.

What the Frequently Disclosed Companies Do

Beyond the technology cluster, the record includes single disclosed transactions in Dell Technologies (enterprise hardware and infrastructure), Netflix (streaming entertainment), UnitedHealth Group (health insurance and pharmacy benefits through its Optum and UnitedHealthcare segments), and Walmart (retail and e-commerce). It also includes a purchase, dated June 15, 2026, in an instrument identified in the data as "SpaceX CDR (CAD Hedged)," while the security name is listed as "Space Exploration Technologies Corp. - Class A Common Stock (SPCX) [ST]." No sector or company description is available for that instrument in the underlying data.

BlackRock, tied with Microsoft as the most frequently disclosed name by transaction count and the only one of those two appearing exclusively as sales, is an investment manager serving institutional and individual clients through separate accounts, mutual funds, ETFs, and alternative strategies. Microsoft, Nvidia, Apple, and Meta need little introduction to investors: they represent, respectively, enterprise and consumer software and cloud infrastructure, data-center AI computing hardware, consumer hardware and services, and social and AI-driven consumer platforms. ServiceNow provides cloud-based digital workflow software used by large enterprises and government agencies.

On Quantellect's own scoring framework, McGuire's disclosed trading carries a Quantellect Score of 9, placing him in the "weak" tier and ranked 70th of 76 members in the scoring cohort as of August 21, 2026. For context, the dataset lists 537 sitting members of Congress, 276 of whom have no disclosed trades. It lists 76 members with a score, 73 of whom are sitting members. The weak tier and 70th-place cohort rank describe where this disclosure record falls within Quantellect's scored group; they do not attribute any transaction to McGuire personally.
