David Phillips is Director at MERIDIAN BIOSCIENCE INC (VIVO). They have made 9 open-market trades across 2 companies since 2006, most recently 2022-01-12.
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.
6 open-market purchases totalling $576K since 2009, against 3 sales. Across 6 scored buys the stock is down 4.2% at ninety days, and 6.1 points behind the S&P over the same stretch.
