Michael J. Rossi files SEC Form 4 disclosures for CALIFORNIA WATER SERVICE GROUP. They have made 16 open-market trades across 3 companies since 2006, most recently 2025-09-16.
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.
4 open-market purchases totalling $300K since 2010, against 12 sales. Too few scored purchases to measure a record yet.
