Insider cluster: 2 insiders, $1.2M total
Actionable Insight • Neutral

Insider cluster at MIAX shows a director and an EVP selling $1.21M in open-market sales (0.03% of market cap) plus several non-cash derivative exercises and tax-withholding events. The net cash outflow is modest relative to the $3.8B market cap, and the filings carry non-informative grant and tax transactions. Sentiment is neutral given the small proportional size of the cluster sales and the lack of a clear catalyst.
