CapitolRadar analysis
5 disclosed trades, all tied to one trader
5 tracked CMS trades were disclosed from May 31, 2023 through January 29, 2026: 3 buys and 2 sells. The activity came from one distinct trader, making this a very small sample rather than a broad pattern across multiple filers. CMS Energy Corporation is classified in the Utilities sector and Regulated Electric industry.
3 buys were attributed to Ro Khanna, with the latest dated October 30, 2025. Because the same individual accounts for all tracked activity, the buy-versus-sell split describes one trader’s disclosures and does not show agreement or disagreement among a wider group.
2 trades in 2023 Q2, then isolated quarterly activity
2 trades occurred in 2023 Q2, including one buy. The remaining activity was spread across three separate quarters: one buy in 2024 Q2, one buy in 2025 Q4, and one trade with no buys in 2026 Q1. Given the total of only five trades, quarter-to-quarter changes can be driven by a single disclosure and should be read cautiously.
6 other tickers appeared in the buyer’s disclosed purchases
6 companies were also bought by the CMS buyer: ADI, ARES, CARR, CSCO, EW and HD. Each overlap represents one buyer—the same size as the entire CMS buyer sample—so these co-purchases provide portfolio context but not evidence of a recurring multi-trader theme.
45 days is the relevant potential disclosure lag, meaning reported activity may become public well after the transaction date. Disclosed transaction amounts, when presented as ranges, are estimates rather than exact values; no transaction amounts are provided here. The single-trader, five-trade sample is too small for broad conclusions about congressional trading interest in CMS.
