CapitolRadar analysis
10 trades split 6 buys to 4 sells
CNM has 10 tracked trades from September 29, 2023 through August 25, 2026, covering activity by two distinct traders. The total divides into six buys and four sells. Michael McCaul accounts for all six recorded buys, with his latest buy dated September 30, 2025. Because the sample includes only 10 transactions and two traders, the apparent buy majority should be read as a narrow record rather than a broad measure of congressional or insider sentiment toward Core & Main.
3 buys concentrated in 2025 Q3
The most active quarter was 2025 Q3, with three trades, all buys. Single buys also appeared in 2023 Q3 and 2023 Q4. Activity in 2024 Q3 consisted of two trades—one buy and, by the reported totals, one sell. The remaining reported quarters were sell-only: one trade in 2025 Q2, one in 2026 Q2 and one in 2026 Q3. This pattern places half of the six tracked buys in one quarter, while the four sells were distributed across four separate quarters. The limited transaction count makes quarter-to-quarter comparisons especially sensitive to individual filings.
1 buyer also reported ATR, KEYS and four other holdings
One of the CNM buyers also bought ATR, KEYS, VTI, AJG, IFNNY and VEA. These overlaps show that the disclosed buyer’s activity was not limited to CNM, but the data do not provide trade sizes, portfolio weights or reasons for any transaction. They therefore cannot establish conviction, strategy or relative preference among the securities.
Congressional transaction disclosures may be filed up to 45 days after a trade, so reported activity is not necessarily current when published. Disclosed dollar amounts are generally reported as ranges, making any transaction-value estimates approximate. Those timing and valuation limits, together with the small sample of 10 trades and two traders, constrain conclusions from the record.
