A story on the same day is not a cause, and a group move is not proof either. Group: the median of SYK, MMM, BSX and BDX that day, the largest companies in PEN’s SEC industry; “moved with PEN” means the same direction and at least half the size.

PEN against four medical device peers, a year at 100

PEN is up 28.9% in a year. All four did less: 3M (+7.9%), Becton Dickinson (+1.4%), Stryker (−21.3%) and Boston Scientific (−55.3%). Weekly closes, Oct 17, 2025 = 100, on a log scale, so the same percentage move is the same height on every line.
