CapitolRadar analysis
18 trades split between 8 buys and 10 sells
Teradyne, Inc. (TER), a Technology / Semiconductors company, had 18 tracked trades by four distinct traders from February 23, 2021 through May 1, 2026. The activity comprised eight buys and 10 sells, leaving sells ahead by two transactions. This is a small sample spanning more than five years, so individual filings and low-count quarters can materially affect the apparent balance.
The supplied quarterly entries account for 14 of the 18 tracked trades. Among those entries, 2022 Q2 was the busiest period, with four trades split between two buys and two sells. Both trades in 2022 Q3 and both in 2022 Q4 were sells. The listed activity also includes one sell in 2022 Q1, one buy in 2023 Q2, one sell in 2023 Q4 and one sell in 2024 Q2.
2 buys mark the listed 2026 Q2 activity
2026 Q2 contains two trades, both buys. Ro Khanna recorded four TER buys overall, with the latest dated May 1, 2026. Michael McCaul recorded one buy, dated April 29, 2026. The other disclosed buyers were Susie Lee, with two buys and a latest date of April 1, 2021, and Tommy Tuberville, with one buy dated March 29, 2021. Together, these four traders account for all eight tracked buys.
6 other tickers show two-buyer overlap
Among the TER buyers, two also bought each of AJG, INTU, BSX, WDAY, DHR and MA. The supplied data does not identify which two buyers overlap on each ticker, transaction timing, or amounts, so the pattern should not be read as coordinated activity or a shared rationale.
Congressional transaction disclosures can appear with a 45-day reporting lag, meaning filing visibility may trail the trade date. Reported transaction values also use amount ranges, so any dollar totals derived from them are estimates; no amount ranges were supplied here. These timing and valuation limits are especially important for this small set of 18 trades and for quarters containing only one or two disclosures.
