CapitolRadar analysis
45 tracked PH trades split 25 buys and 20 sells
The record covers 45 Parker-Hannifin Corporation trades by five distinct traders from July 26, 2020 through August 11, 2026. Buys account for 25 trades, compared with 20 sells. This is a small group of traders, so the balance should be read as a description of the disclosed sample rather than a broad measure of congressional sentiment toward PH or the Industrials / Industrial - Machinery industry.
The listed quarterly activity is uneven. The busiest shown period was 2023 Q4, with five trades: two buys and three sells. In 2024 Q4, all four trades were sells. By comparison, both trades in 2024 Q2 and both trades in 2026 Q1 were buys. The single trades in 2023 Q3, 2025 Q3 and 2026 Q3 were sells. In 2024 Q1, one of three trades was a buy.
18 of 25 buys came from Ro Khanna
Ro Khanna recorded 18 PH buys, or 72% of all tracked purchases, with the latest dated June 14, 2024. Kevin Hern accounted for four buys, last dated November 26, 2021. Jared Moskowitz recorded two, most recently on March 31, 2026, while Markwayne Mullin recorded one on June 12, 2024. The concentration in one buyer and the four-person buyer sample limit how broadly the purchase pattern can be interpreted.
Six other tickers overlapped across two PH buyers each
Among the PH buyers, two also bought AXP, two bought CB, two bought META, two bought HD, two bought MCD and two bought PANW. The data does not identify whether the same pair appears in each overlap.
Congressional transaction reports can be disclosed with a lag of up to 45 days, so filing visibility may trail the underlying trade date. Disclosed transaction amounts are reported as ranges, making any dollar-value estimates approximate. These timing and valuation limits are especially relevant given the small trader and quarterly samples.
