CapitolRadar analysis
24 ECL trades split between 11 buys and 13 sells
Ecolab Inc. (ECL), a Basic Materials company in the Specialty Chemicals industry, had 24 tracked trades from January 11, 2022 through May 1, 2026. The activity comprised 11 buys and 13 sells, making the disclosed direction nearly balanced but with two more sales than purchases. All 24 transactions came from one distinct trader, so the record reflects a single person’s disclosures rather than a broad pattern across multiple congressional or insider traders.
2 buys in 2026 Q2 followed a sale-only first quarter
The latest reported activity was two buys in 2026 Q2, with the most recent purchase dated May 1, 2026. Ro Khanna was the sole tracked buyer, accounting for all 11 ECL purchases. The immediately preceding quarter, 2026 Q1, contained one trade and no buys. Earlier disclosed periods were uneven: 2025 Q3 had one trade with no buys; 2024 Q1 had two trades with no buys; and 2023 Q4 had one trade with no buys. In 2023 Q1, one of three trades was a purchase. The strongest buy concentration in the supplied quarterly data was 2022 Q3, when all four trades were buys, while 2022 Q4 had one trade and no buys.
1 buyer links ECL with six other disclosed tickers
The same tracked ECL buyer also bought AME, BK, CMCSA, DHR, FTNT and IP. Each overlap represents one buyer because the ECL buyer sample contains only Ro Khanna. These co-purchases show disclosed ticker overlap, but the sample is too small to establish a broader trading pattern or infer intent.
Congressional transaction reports can appear up to 45 days after a trade, so disclosure timing may lag the underlying activity. Reported transaction amounts, when shown as ranges, are estimates rather than exact values. The one-trader sample and the small trade counts in most quarters also limit comparisons and general conclusions.

CapitolRadar signal history
NEW PICK 2026-10-12
Rep. Ro Khanna disclosed buying $1,001 to $15,000 of Ecolab stock. The trade fell short mainly because Khanna has no verified history of beating the market after similar purchases, so the signal is unproven. A reliable backtest showing repeated outperformance after his trades could have changed the verdict; the biggest caveat is the 28-day disclosure delay and unknown purchase price.
NEW PICK 2026-09-14
Ecolab director Eric Mark disclosed an open-market purchase of about $88,733 in ECL stock. The panel passed mainly because he has no verified trading history versus SPY, so the buyer signal is unproven despite the prompt disclosure. A documented record of his prior purchases outperforming SPY would have provided the clearest evidence for a different verdict.
