Congressional stock purchases in the technology sector have produced exceptional performance when measured strictly from their disclosure dates forward. Each of these positions became visible to the public on the filing date, meaning any investor reviewing the disclosures at the time could have tracked the subsequent returns. Data from disclosedcapitol.com identifies six such buys by three House members that have posted gains ranging from 327 percent to 817 percent since those filings were released.
Ro Khanna, a California Democrat, disclosed a purchase of STX on April 10, 2025. This position, which we are still verifying as an outlier, has returned 817.29 percent since disclosure. The same member disclosed a WDC purchase on January 6, 2026 that we are also reviewing as an outlier, showing a 786.25 percent return from the filing date. Gilbert Cisneros, another California Democrat, filed for SNDK on February 13, 2026. This too is an outlier we are still verifying, with a return of 660.49 percent since it became public.
Verified filings show similarly strong results. Cisneros disclosed a buy in SPHR on May 6, 2025 that has gained 420.42 percent since disclosure. Lisa McClain, a Michigan Republican, filed two technology purchases on August 13, 2025. Her DELL position has returned 371.53 percent from the disclosure date while the CIEN purchase has delivered a 327.71 percent gain over the same measured period. These trades, primarily in technology with one in communication services, carried holding periods between 237 and 607 days.
The consistent outperformance across these independently filed positions highlights how certain disclosed congressional trades have aligned with strong sector moves after the information reached the public domain. While the outliers require additional verification before final confirmation, the verified trades alone demonstrate returns well above broad market benchmarks from the moment the filings were available. Market conditions, sector tailwinds in data storage and networking, and broader technology spending trends likely contributed, though exact causation remains unclear. Investors tracking such disclosures should note that future results may differ substantially from past patterns observed here.
