We analyzed 30,763 congressional stock trades filed under the STOCK Act from 2018–2026. Buying every congressional trade indiscriminately underperforms the S&P 500 by 2.40% at 180 days — Congress, in aggregate, is not a better stock picker than the index. But filtered for bipartisan clusters with committee relevance, the same dataset produces +6.22% alpha at 180 days. The ~9-point spread between the baseline and the signal is what Signal Congress finds.
Read our full methodology and statistical caveats →Starting from all 30,763 congressional trades, we applied progressively tighter filters. The unfiltered baseline loses to the market. The right filter finds significant alpha. Each strategy below is independent — not a funnel.
The strongest bipartisan buy clusters the engine flagged, ranked by cluster strength, each shown with the realized 60-day price move that followed. Outcomes appear as-is — gains and losses alike. Ranking is by signal strength, not by return, and every cluster from this period feeds the aggregate stats above; nothing here is selected for performance.
