Congressional trade disclosures continue to surface purchases that recorded outsized gains after entering the public record. These returns are measured from the DISCLOSURE date forward, and the public could have seen each of these positions when they were filed. Our review of the latest filings identifies six notable examples across four lawmakers where post-disclosure performance has been particularly strong, spanning technology, healthcare, and communication services sectors. The data we analyzed shows clear outperformance relative to broader indices in the periods following each filing.
Topping the list is Rep. Lisa McClain's purchase of SNDK, disclosed November 21, 2025. This position, an outlier we are still verifying, shows a return of 891.32 percent. Rep. Ro Khanna recorded a buy in CCG disclosed on February 6, 2026. This too is an outlier we are still verifying, returning 764.2 percent since the filing. Khanna's separate purchase of MRNA, disclosed January 6, 2026, is likewise an outlier we are still verifying and has returned 593.7 percent from that date. Each of these filings was available to any investor reviewing official disclosures on the specified dates.
Among positions not marked for further review, McClain's CIEN buy disclosed August 13, 2025 has delivered a 387.77 percent return. Rep. Tim Moore purchased TZA with a disclosure date of July 9, 2025, producing a 310.19 percent gain since then. Sen. Mark R Warner added TEAM, disclosed May 1, 2026, which stands at a 264.67 percent return. These verified trades, like their counterparts, involved amounts ranging from $1,001 to $15,000 and occurred at prices that subsequent market moves turned into significant appreciation. Days held range from 191 to 647, demonstrating both shorter-term and multi-year holding periods.
The four distinct members involved represent both parties and both chambers, with technology appearing most frequently. Current alpha figures for these trades range from 252 to 877 points above benchmark performance in the same windows, according to our calculations from the filing data. While such results do not predict future patterns and individual trade sizes were modest, the consistency of post-disclosure strength in these names merits attention from investors tracking official filings. Market conditions, sector tailwinds, and company-specific developments all contributed, yet the overlap in timing between disclosure and subsequent price appreciation is notable in the data set.
