Nelson C. Chan is Director at SYNAPTICS INC (SYNA). They have made 19 open-market trades across 2 companies since 2006, most recently 2025-02-05.
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 19 sales. Too few scored purchases to measure a record yet.
