Rep. Lisa McClain's purchase of SNDK stands out sharply in the latest congressional trading data. Disclosed on November 21 2025 this technology sector buy is an outlier we are still verifying showing a 937.77 percent return over 348 days held. The filing fell in the $1,001 to $15,000 range and became public record on that November date.
These returns are measured from the DISCLOSURE date forward and the public could have seen each of these positions when they were filed. Any investor reviewing official disclosures on congress.gov or the House and Senate ethics portals would have had full visibility into the tickers amounts and exact filing dates. The data reveals that positions available in plain sight have produced extraordinary gains in the periods following disclosure.
Rep. Ro Khanna added two more standout filings both disclosed January 6 2026. His WDC purchase is an outlier we are still verifying with a 662.25 percent return since filing while the MRNA position delivered 506.09 percent across 639 days. Both trades were also sized between $1,001 and $15,000 and spanned the technology and healthcare sectors. These add to Khanna's pattern of early-year activity that has aligned with significant post-disclosure appreciation.
Verified positions reinforce the trend. McClain's DELL buy disclosed August 13 2025 has returned 434.61 percent. Rep. Tim Moore's TZA filing disclosed July 9 2025 produced a 312.24 percent gain despite recent negative 90-day performance. Rep. Gilbert Cisneros disclosed a larger $15,001 to $50,000 purchase of SPHR on May 6 2025 that has returned 284 percent with a 376 percent one-year mark. Four distinct members across parties contributed to this group of outperformers with clear concentration in technology communication services and healthcare.
The alpha figures tell a similar story frequently clearing 400 percentage points above benchmark moves during the hold periods. While some trades show shorter-term volatility the multi-month returns measured strictly after public disclosure remain striking. This dataset of six purchases with minimum 284 percent gains since filing offers a fresh look at how certain disclosed congressional buys have translated into measurable outperformance once visible to the public. Ongoing verification continues for the highest figures.
