Mark Corrigan is Executive VP & R&D at SEPRACOR INC /DE/ (SEPR). They have made 10 open-market trades across 5 companies since 2006, most recently 2025-12-08.
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.
0 open-market purchases, against 10 sales. Too few scored purchases to measure a record yet.
