CapitolRadar analysis
16 tracked STX trades split into 7 buys and 9 sells
Seagate Technology Holdings plc (STX), a Technology / Computer Hardware company, recorded 16 tracked trades by four distinct traders between May 19, 2021 and September 30, 2026. The activity comprised seven buys and nine sells, so sells represented a modest majority of the disclosed transactions. The sample remains small: 16 trades across four traders is not enough to establish a broad or persistent trading pattern.
The quarterly record is uneven. The largest cluster was 2022 Q2, with five trades and two buys. That was followed by 2022 Q4, when all three tracked trades were buys. By contrast, 2024 Q1 and 2025 Q4 each had two trades and no buys. The 2026 data show one buy in Q2, followed by two trades and no buys in Q3. One additional buy occurred in 2021 Q2.
6 of the 7 buys came from Ro Khanna
Ro Khanna accounted for six buys, with the latest dated April 13, 2026. Marjorie Taylor Greene accounted for the remaining buy, dated May 19, 2021. Together, these two disclosed buyers represent all seven tracked STX purchases in the dataset. Because the buying side is concentrated in only two people—and primarily in one trader—the record should not be read as evidence of widespread buying among the four tracked traders.
1 buyer overlap appears across six other tickers
Among the STX buyers, one also bought LEN, one bought MDT, one bought NFLX, one bought PFE, one bought REGN and one bought STE. The supplied data do not identify whether the same buyer accounts for each overlap, nor do they provide dates, values or transaction counts for those other purchases.
Disclosure timing and valuation limits apply throughout. Congressional transaction reports can appear up to 45 days after a trade, so disclosure dates may lag the underlying activity. Reported transaction amounts are generally ranges rather than exact values, making any dollar totals estimates. The limited number of trades and traders further constrains comparisons across quarters.
