CapitolRadar analysis
22 disclosed ON trades split 13 buys to 9 sells
The tracked record for ON Semiconductor Corporation covers 22 trades by three distinct traders from October 10, 2019 through May 1, 2026. Buys account for 13 transactions, compared with nine sells. That produces a modest buy majority by transaction count, but the sample is small and does not show the relative dollar size of buying versus selling.
Activity was concentrated in a few reported quarters. The largest listed quarter was 2024 Q1, with seven trades: four buys and three sells. The next-largest was 2023 Q4, with three trades, including two buys. Both 2023 Q2 trades were sells, while both 2022 Q4 trades were buys. The listed 2026 activity consists of one sell in Q1 and one buy in Q2, underscoring how little evidence each recent quarter provides on its own.
8 buys from Ro Khanna lead a three-buyer sample
Ro Khanna recorded eight ON purchases, the most among the three named buyers, with the latest dated May 1, 2026. Josh Gottheimer made three purchases, most recently on January 11, 2024. Susie Lee made two purchases, with the latest on August 20, 2021. Together, those counts account for all 13 tracked buys, although the limited number of traders makes broad conclusions inappropriate.
2 buyers also purchased ADI, FCX, GOOGL and PANW
Two of the ON buyers also bought each of ADI, FCX, GOOGL and PANW. One also bought APP, and one also bought BRO. These overlaps describe disclosed transaction histories only; they do not establish a common strategy, sector thesis or motive.
Congressional transaction disclosures can be reported with a lag of up to 45 days, so trade dates should not be treated as real-time signals. Disclosed transaction amounts are reported in ranges, making any dollar totals or comparisons estimates rather than exact figures. The 22-trade, three-trader sample is also too small to support strong generalizations.

CapitolRadar signal history
NEW PICK 2026-10-13
Rep. Gilbert Cisneros disclosed buying $15,001–$50,000 of ON stock. The panel passed mainly because he has no verified trading history versus the S&P 500, so the buyer signal is unproven despite another tracked buyer. A documented record of prior purchases outperforming the market would have strengthened the case; the biggest caveat is that the trade-date price is unavailable, preventing a return check.
