CapitolRadar analysis
4 trades across four quarters, with 3 buys and 1 sell
COHR has 4 tracked trades from November 3, 2022 through May 1, 2026: 3 buys and 1 sell. The activity is spread across four separate quarters rather than concentrated in a short period. The quarterly record shows 1 buy in 2022 Q4, 1 sell in 2023 Q2, 1 buy in 2025 Q4 and 1 buy in 2026 Q2. Each active quarter contains only a single transaction, and there are no additional tracked trades in the supplied data.
The overall direction is buy-heavy by transaction count, with purchases representing 3 of the 4 disclosures. However, this is a small sample, and transaction counts alone do not establish the relative dollar weight of buying versus selling. Any disclosed transaction amounts are reported as ranges, so derived dollar values should be treated as estimates rather than exact figures.
1 trader accounts for the full COHR record
All 4 tracked COHR trades come from 1 distinct trader. Ro Khanna is identified as the buyer, with 3 purchases and a most recent buy dated May 1, 2026. Because the dataset contains only one distinct trader, the apparent pattern reflects one person’s disclosures rather than broad participation by multiple congressional or insider filers.
Disclosure timing is also an important limitation. Congressional transactions may be reported with a lag of up to 45 days, so the public filing date may not coincide with the underlying trade date. That delay can make the activity less timely when viewed after disclosure.
6 other tickers appear alongside this buyer
The same COHR buyer also bought ACGL, AMZN, BR, CPRT, EME and GOOGL. Each overlap is attributed to 1 buyer—the same size as the entire COHR buyer sample. These cross-holdings span the supplied ticker list, but the data provides no trade amounts, timing relationships or stated rationale connecting them to COHR. Given the single-buyer sample, the overlaps describe that trader’s disclosed activity and should not be interpreted as a wider group pattern.
