Could not find a ticker for this position, may be a filing error
A digital healthcare company that makes wearable heart monitors, best known for its Zio patch — a small peel-and-stick sensor patients wear for up to two weeks, including in the shower, to continuously record their heartbeat while AI software helps spot irregular rhythms. A cardiologist, Dr. Uday Kumar, founded it in 2006 after struggling with bulky Holter monitors that missed intermittent heart problems. The Zio patch, worn comfortably during normal daily life, was designed to be water-resistant so patients could shower and exercise while being monitored.

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 all recorded history: -3.96M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
