Stryker Corp
A maker of medical devices and surgical robotics, Stryker sells everything from joint replacements and spinal implants to endoscopes and the Mako robotic surgery platform, used by hospitals and surgeons around the world. It began in 1941, when Michigan orthopedic surgeon Dr. Homer Stryker, frustrated that his tools didn't work, started the Orthopedic Frame Company in his basement to sell his own inventions—including a cast cutter he built from a malted milk mixer motor. The firm was renamed Stryker in 1964 when its founder retired.

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 year: -1.35M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
