CapitolRadar analysis
25 tracked TDY trades skew toward sales
25 trades in Teledyne Technologies Incorporated were tracked from April 25, 2019 through September 25, 2026. The activity comprises 9 buys and 16 sells by four distinct traders, so sales represent the larger side of this limited record. TDY is classified in the Technology sector and the Hardware, Equipment & Parts industry.
The most active listed quarter is 2026 Q3, with six trades and no buys. Earlier disclosed activity was mixed: 2023 Q4 had three trades, including one buy; 2023 Q3 had two trades, both buys; and 2022 Q2 had three trades, including two buys. The remaining listed quarters each contained one or two trades. Because the dataset covers only four traders and 25 transactions, quarter-to-quarter changes reflect a small sample rather than broad congressional participation.
9 buys came from two disclosed buyers
Ro Khanna accounted for six buys, with the latest dated November 3, 2023. Susie Lee accounted for three buys, with the latest dated May 26, 2021. Together, their nine purchases equal the full buy count in the tracked TDY activity. The provided facts do not identify the sellers or allocate the 16 sales among the four distinct traders.
6 other tickers overlap with one TDY buyer each
One of the two TDY buyers also bought each of AMD, BAX, CASY, COF, CVS and ES. The data does not specify which buyer made each overlapping purchase, nor does it provide dates, frequencies or amounts for those other tickers, so the overlap is descriptive only.
Congressional disclosures can be filed up to 45 days after a transaction, meaning reported activity may not be visible promptly. Disclosed dollar amounts are generally presented as ranges and should be treated as estimates; no transaction-value ranges were supplied here. The small number of traders and trades also limits broader interpretation.
