CapitolRadar analysis
28 tracked MRVL trades split evenly between buys and sells
Marvell Technology, Inc. (MRVL), in the Technology sector and Semiconductors industry, has 28 tracked trades from October 4, 2019 through August 7, 2026. The activity is evenly divided between 14 buys and 14 sells across three distinct traders. That balance describes the full disclosed record, but the sample remains small: three traders are not broad evidence of congressional sentiment toward the company or semiconductor industry.
The eight quarterly snapshots provided contain 17 trades. The busiest listed period was 2022 Q4, with four trades comprising one buy and three sells. Both 2023 Q1 trades were buys, while all three trades in 2023 Q2 were sells. More recent listed activity was buy-only: one trade in 2026 Q2 and three trades in 2026 Q3. The provided quarter list is not a complete quarter-by-quarter breakdown of all 28 trades.
11 of 14 buys came from Ro Khanna
Ro Khanna accounted for 11 buys, with the latest dated August 7, 2026. Susie Lee recorded two buys, most recently on November 8, 2019, while Gilbert Cisneros recorded one buy dated July 17, 2026. Together, those counts equal all 14 tracked purchases. Because the buying record is concentrated among three people—and especially one trader—it should be read as a limited disclosure sample rather than a diversified pattern.
6 other tickers overlapped among two MRVL buyers
Two of the identified MRVL buyers also bought each of INTU, NVDA, ETN, IBM, WMT and ACN. These overlaps show common holdings among a small buyer group, but the supplied data does not establish timing relationships, trade sizes or motives.
Congressional transaction reports can appear up to 45 days after a trade, so disclosure dates may lag the underlying activity. Reported transaction values are generally presented as ranges, making any amount-based estimates approximate; no dollar ranges were provided here.

CapitolRadar signal history
NEW PICK 2026-09-09
Rep. Gilbert Ray Cisneros disclosed buying $1,001 to $15,000 of Marvell Technology stock. The panel passed mainly because he has no verified trading history versus SPY, so this buyer signal is unproven. A documented record of similar trades outperforming SPY—or several other tracked buyers purchasing MRVL near the same time—would have strengthened the case enough to reconsider.
NEW PICK 2026-09-07
Rep. Gilbert Cisneros disclosed a $1,001–$15,000 purchase of Marvell Technology. The panel passed mainly because he has no verified trading record against the S&P 500, so the buyer signal is unproven; a documented history of similar trades outperforming the index would have strengthened the case. The biggest caveat is that the listed 2026 trade and disclosure dates are future-dated and cannot yet be verified.
