Eric Wei is Director at CCC Intelligent Solutions Holdings Inc. (CCCS). They have made 18 open-market trades across 4 companies since 2010, most recently 2025-11-07.
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 $1.0M since 2010, against 17 sales. Too few scored purchases to measure a record yet.
