Kenneth H. Traub is Director at ATHERSYS, INC / NEW (ATHX). They have made 18 open-market trades across 8 companies since 2009, most recently 2023-06-26.
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.
18 open-market purchases totalling $1.9M since 2009, never a sale. Across 13 scored buys the stock is down 1.5% at ninety days, and 4.8 points behind the S&P over the same stretch.
