Congressional STX Filing Hits 910 Percent Gain Since Disclosure

All returns discussed in this report are measured from the disclosure date forward. These positions were filed publicly, meaning any investor could have seen and followed each one from the date it was released.

Disclosed congressional purchases continue to show striking performance in the data, with six buys from three House members producing exceptional gains after filing. The standout is a technology purchase by Ro Khanna that has returned 910.45 percent since its disclosure. Because this position is marked needs_review, we describe it as an outlier we are still verifying rather than asserting the figure. Khanna, a California Democrat, filed the STX purchase on April 10, 2025. The same member disclosed a WDC purchase on January 6, 2026 that has returned 815.31 percent; this too is an outlier we are still verifying.

Gilbert Cisneros, another California Democrat, filed an SNDK buy on February 13, 2026. This position, also an outlier we are still verifying, has returned 794.28 percent since disclosure. Cisneros' verified SPHR purchase, disclosed May 6, 2025 in the communication services sector, has delivered a 443.38 percent return. Lisa McClain, a Michigan Republican, disclosed two technology buys on August 13, 2025. Her DELL position has returned 431.83 percent while the CIEN filing has gained 374.88 percent.

These trades, all in technology or communication services, underscore how certain disclosed congressional purchases have substantially outperformed from the moment they entered the public domain. The pattern appears across party lines yet remains concentrated in a narrow set of sectors that benefited from strong market tailwinds after the filings. With holding periods ranging from 253 to 623 days, the data illustrates the range of outcomes possible when tracking official disclosures rather than attempting to anticipate them.
