Edward F. Smith is CFO at MARINUS PHARMACEUTICALS INC (MRNS). They have made 5 open-market trades across 1 company since 2018, most recently 2021-03-09.
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 5 sales. Too few scored purchases to measure a record yet.
