Negative

  • Dispositions of 8,411 shares reported across multiple sales at high weighted-average prices (~$627.56 to $628.89), reducing direct holdings to 7,131.9435 shares.
  • Significant transaction volume (total shares bought and sold equal 8,411) may be viewed by some investors as notable insider trading activity given the large absolute share counts.

Insights

TL;DR: Insider reported matched purchases and sales totaling 8,411 shares, leaving ~7,132 shares directly owned.
