CapitolRadar analysis
21 VMC trades split almost evenly
Vulcan Materials Company has 21 tracked trades from 2021-05-18 through 2026-09-25: 10 buys and 11 sells by three distinct traders. That leaves selling ahead by only one transaction, so the aggregate direction is nearly balanced. The sample is small, however, and trade counts do not show whether the estimated dollar value of purchases matched the estimated value of sales.
Buying was concentrated: Ro Khanna accounted for eight of the 10 buys, with the latest dated 2026-09-25. Michael McCaul had one buy, last dated 2025-03-21, and Marjorie Taylor Greene had one, dated 2021-05-18. Khanna therefore represented 80% of tracked purchase transactions, making the apparent buying pattern heavily dependent on one trader rather than broadly distributed across the three.
7 trades in the first three quarters of 2026
The supplied quarterly data show seven trades in 2026 through Q3. Q1 had one trade and no buys; Q2 had three trades, including two buys; and Q3 had three trades, including one buy. Combined, those quarters produced three buys and four sells. The two most recent quarters alone were evenly split at three buys and three sells across six transactions.
Earlier listed activity was sparse: one sell in 2025 Q4, one sell in 2025 Q2, one buy in 2025 Q1, one buy in 2024 Q1, and one buy in 2023 Q4. Because only 21 trades and three traders are represented, quarter-to-quarter changes can be driven by very few disclosures.
6 shared holdings appear among two buyers each
Two of the VMC buyers also bought each of DHR, WDAY, MA, AJG, META, and TER. The data do not identify whether the same two buyers overlap in every name, nor do they establish timing or a common rationale.
Congressional disclosures may be filed up to 45 days after a transaction, so public visibility can lag the trade date. Reported transaction amounts are ranges and any dollar totals derived from them are estimates. These limitations are especially material for this small sample.
