CapitolRadar analysis
69 tracked ASML trades split nearly evenly
ASML Holding N.V. has 69 tracked trades from seven distinct traders between October 15, 2019 and April 17, 2026. The activity comprises 33 buys and 36 sells, giving sells a three-trade edge across the full period. ASML is classified in the Technology sector and Semiconductors industry. Although the overall record spans several years, seven traders remain a small sample, so individual activity can materially affect the totals.
38 trades across the latest eight reported quarters
The eight quarters from 2024 Q3 through 2026 Q2 contain 38 trades: 15 buys and 23 sells. Buying was concentrated in 2025 Q2, when seven of nine trades were buys. By contrast, all two trades in 2024 Q3, all five in 2025 Q4 and both trades in 2026 Q2 were sells. Other quarters were mixed: 2024 Q4 had three buys among eight trades; 2025 Q3 had one among three; 2026 Q1 had three among eight. The single 2025 Q1 trade was a buy. These quarterly counts are small, particularly in quarters with only one to three disclosures.
12 buys led by Michael McCaul
Michael McCaul recorded 12 buys, the most among the named buyers, with the latest dated June 26, 2025. Ro Khanna followed with eight, last dated January 9, 2026, and Marjorie Taylor Greene had seven, last dated September 11, 2025. Josh Gottheimer recorded three buys, Jared Moskowitz two and Kevin Hern one. Among these buyers, three also bought META and three bought PANW; two each also bought AJG, FCX, IFNNY and BAX. These overlaps describe disclosed activity only and do not establish a common rationale.
Congressional disclosures can be filed up to 45 days after a transaction, so reported dates may not reflect real-time positioning. Disclosed dollar amounts are generally ranges rather than exact values, making any amount-based estimates approximate; no transaction amounts are provided here.
