Erin C. McGlaughlin is Director at YORK WATER CO (YORW). They have made 41 open-market trades across 1 company since 2017, most recently 2026-05-04.
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.
41 open-market purchases totalling $44K since 2017, never a sale. Across 41 scored buys the stock is up 2.8% at ninety days, and 0.7 points ahead of the S&P over the same stretch.
