William H. Miller III is 10% Owner at Wright Investors Service Holdings, Inc. (IWSH). They have made 2 open-market trades across 2 companies since 2020, most recently 2025-12-19.
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.
2 open-market purchases totalling $331K since 2020, never a sale. Too few scored purchases to measure a record yet.
