Thomas L. Williams is CEO & Chairman at PARKER HANNIFIN CORP (PH). They have made 19 open-market trades across 2 companies since 2006, most recently 2025-04-04.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
1 open-market purchase totalling $240 since 2006, against 18 sales. Too few scored purchases to measure a record yet.
