CapitolRadar analysis
4 disclosed DCO trades, concentrated in two quarters
Ducommun Incorporated (DCO), an Industrials company in the Aerospace & Defense industry, recorded 4 tracked trades by 2 distinct traders from October 11, 2023, through August 7, 2026. The activity comprised 3 buys and 1 sale, so purchases represented three-quarters of this small set.
The disclosures were concentrated in two periods. The third quarter of 2026 accounted for 3 trades, including 2 buys; given the overall totals, the remaining Q3 transaction was the single sale. The fourth quarter of 2023 contained 1 trade, which was a buy. With only four observations across two traders, the record is too limited to establish a broad or persistent trading pattern.
2 buyers, with Gilbert Cisneros accounting for most purchases
Gilbert Cisneros made 2 of the 3 tracked DCO buys, with the latest dated July 10, 2026. Josh Gottheimer made 1 buy, dated October 11, 2023. Cisneros therefore represented two-thirds of purchases by transaction count, while Gottheimer represented one-third. The provided data does not identify the trader responsible for the sale, so no attribution can be made beyond the disclosed buyer records.
4 stocks overlap across both buyers’ other purchases
Both DCO buyers also purchased Goldman Sachs (GS), CrowdStrike (CRWD), Microsoft (MSFT), and Advanced Micro Devices (AMD). Additional purchase overlap was narrower: 1 of the 2 buyers also bought CDW, and 1 also bought Glacier Bancorp (GBCI). These co-purchases describe portfolio activity only; they do not establish a connection between those companies and DCO.
Disclosure timing is an important limitation: reported trades can appear up to 45 days after execution, so the dates available to the public may lag the underlying activity. Transaction amounts, when reported as ranges, are estimates rather than exact values. No amount ranges were provided here, and the four-trade sample is small.
