Michael A. Pisetsky is CLO & VP at SI-BONE, Inc. (SIBN). They have made 11 open-market trades across 1 company since 2025, most recently 2026-10-02.
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 11 sales. Too few scored purchases to measure a record yet.
