CapitolRadar analysis
33 buys and no sells across three WMB traders
33 tracked WMB trades were recorded from March 25, 2020 through August 20, 2026. All 33 were buys; none were sells. The activity involved only three distinct traders, making the directional split notable within the dataset but based on a small group.
Kevin Hern accounted for 30 of the 33 buys, or about 91% of the tracked transactions, with his latest buy dated March 25, 2024. Alan Armstrong recorded two buys, most recently on August 20, 2026. Ro Khanna recorded one buy, dated April 20, 2023. Because one trader generated nearly all of the observations, the aggregate pattern primarily reflects Hern’s activity rather than broad participation.
15 trades appear in the supplied quarterly breakdown
The listed quarters account for 15 of the 33 tracked trades, all buys. The supplied quarterly data shows two buys in 2026 Q3 and two each in 2024 Q1, 2023 Q3, 2023 Q1, 2022 Q4, 2022 Q3 and 2022 Q2. One buy appears in 2023 Q2. The remaining 18 tracked trades are not detailed by quarter in the provided facts, so no conclusion can be drawn here about their quarterly distribution.
The records span multiple years, but individual quarterly counts are small: every listed quarter contains either one or two transactions. That limits the strength of comparisons between periods.
Six other tickers show one-trader overlap
One of the three WMB buyers also bought each of AME, BK, CHTR, CVS, FDS and HOOD. The data does not identify which WMB buyer overlaps with each ticker, and each overlap involves only one trader. These are therefore small-sample associations rather than broad common-buying patterns.
Disclosure timing can lag a transaction by up to 45 days, so reported activity is not necessarily visible in real time. Transaction amount ranges, when presented, are estimates rather than exact values; no amount ranges were supplied here. The absence of tracked sells and the concentration in one buyer describe this dataset only.
