Neuronetics, Inc.
A maker of non-invasive medical devices that treat mental health conditions, Neuronetics built the NeuroStar system, which uses focused magnetic pulses to stimulate areas of the brain involved in mood. Founded in 2003, it became the first company cleared by the FDA to use transcranial magnetic stimulation for depression that didn't respond to medication. The name blends "neuro" with "kinetics," hinting at its technology that applies moving magnetic fields to nudge underactive brain regions back into action.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -407.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
