CapitolRadar analysis
46 CMCSA trades trace to one filer
46 tracked trades in Comcast Corporation span February 11, 2021 through July 7, 2026: 27 buys and 19 sells. The activity comes from one distinct trader, so the eight-trade difference between buys and sells reflects a single disclosure history rather than a broad pattern across multiple members of Congress.
27 buys are attributed to Ro Khanna, with the latest reported purchase dated July 7, 2026. Because the sample contains only one trader, the buy count should not be interpreted as a consensus signal among congressional filers.
5 trades made 2025 Q3 the busiest listed quarter
5 trades appear in 2025 Q3, including three buys, making it the most active quarter among those provided. The other listed quarters are smaller: three trades with one buy in 2024 Q1; two trades with one buy in 2026 Q1; and one trade each in 2023 Q4, 2024 Q3, 2025 Q4, 2026 Q2 and 2026 Q3.
1 buy was recorded in each of 2023 Q4, 2026 Q2 and 2026 Q3. The single trades in 2024 Q3 and 2025 Q4 were not buys. These quarterly observations are small, and the supplied quarter list does not cover every quarter within the full tracking period.
6 other tickers overlap with the sole CMCSA buyer
6 companies—AME, BK, CMG, DIS, FTNT and IP—were also bought by the tracked CMCSA buyer. With only one buyer in the sample, each overlap represents that same individual and does not establish a wider cross-filer pattern or explain timing or rationale.
45 days may separate a transaction from its disclosure, so reported activity is not necessarily contemporaneous. Transaction values reported as amount ranges produce estimates rather than exact dollar figures. Those disclosure limits, together with the one-trader sample and small quarterly counts, constrain broader conclusions.
