CapitolRadar analysis
2 FSS purchases, 0 sales across two traders
Federal Signal Corporation (FSS), classified in Industrials / Agricultural - Machinery, had 2 tracked trades from February 26 through September 21, 2026. Both were purchases, with no sales recorded. The activity came from 2 distinct traders: Josh Gottheimer made one purchase on February 26, and Gilbert Cisneros made one purchase on September 21.
The transactions were separated across the year rather than clustered in one reporting period. One purchase fell in 2026 Q1 and the other in 2026 Q3. With only two trades and one transaction per buyer, this is a small sample. The 2-to-0 buy/sell split describes only the disclosed activity supplied here and does not establish a broader trading pattern.
4 stocks were common to both FSS buyers
Both FSS buyers also purchased SAIL, MSFT, AMD and CRWD. That gives each of those four tickers an overlap count of 2 among the 2 tracked FSS buyers. The shared purchases show that FSS was one of several names appearing in both buyers’ disclosed activity, rather than the only common security listed in the supplied data.
Additional overlap was narrower: ADI was purchased by 1 of the 2 FSS buyers, and CDW was also purchased by 1. The facts do not identify which buyer purchased ADI or CDW, nor do they provide dates, amounts or sale activity for those other tickers.
Disclosure timing and transaction-size limits
Congressional transaction disclosures may carry a reporting lag of up to 45 days, so the listed trade dates should not be treated as real-time signals. Transaction values in disclosure records are generally reported as ranges, making any amount derived from those ranges an estimate rather than an exact figure. No FSS transaction-size ranges were provided here, so the activity can be counted but not quantified in dollar terms. These timing and sizing limitations are especially important given the two-trade sample.

CapitolRadar signal history
NEW PICK 2026-10-13
Rep. Gilbert Cisneros disclosed buying $1,001 to $15,000 of Federal Signal stock. The panel passed mainly because he has no verified trading history against the S&P 500, so this buyer signal is unproven. A documented record of his prior purchases consistently outperforming the market would have strengthened the case enough to change the verdict; the exact purchase price is also unknown.
