CapitolRadar analysis
362 trades across 120 tickers
Markwayne Mullin disclosed 362 trades from January 3, 2023, through February 25, 2026: 257 buys and 105 sells. Buys represented about 71% of the transactions. The estimated disclosed buy volume was approximately $10,026,629, calculated from the midpoints of reported amount ranges. That figure is an estimate rather than an exact measure of capital deployed because congressional disclosures report transaction values in ranges.
The record covers a broad set of 120 tickers rather than a small group of securities. Even so, transaction counts do not show portfolio weights, holding periods, realized returns or whether one reported trade was substantially larger than another.
54 trades in 2025 Q4 led the listed quarters
Activity varied considerably across the eight listed quarters. The busiest was 2025 Q4 with 54 trades, including 34 buys, followed by 2025 Q1 with 38 trades and 29 buys. The record shows 36 trades in 2024 Q4, 28 in 2026 Q1 through February 25, and 23 in 2025 Q2. Smaller quarterly samples include 11 trades in 2025 Q3, seven in 2024 Q2 and five in 2024 Q3. Those low-count quarters are too small to support strong conclusions about a sustained trading pattern.
Three tickers tied at six disclosed buys
AMAT, ADBE and GS were the most frequently purchased tickers, with six buys each. LRN, LRCX and MSFT followed with five buys apiece, while UNH and LLY each had four. These are frequency rankings only; they do not establish which positions received the most estimated dollars.
No performance grade is available: zero buys have been scored, while five are required for a grade. The backtest sample is therefore insufficient. Disclosures can also appear with a 45-day reporting lag, so reported activity may not reflect current holdings or positioning.
