What Happened

• Judson Teekell, a director of Miami International Holdings, sold a total of 8,545 MIAX shares in open-market transactions on September 2, 2026. The sales consisted of 5,545 shares at a weighted-average price of $41.58 (proceeds $230,561) and 3,000 shares at a weighted-average price of $40.89 (proceeds $122,670), for combined proceeds of approximately $353,231. This was a sale (not a purchase); sales are often routine and do not necessarily indicate a change in insider sentiment.

Context

• Because part of the stock was sold under a Rule 10b5-1 plan and part in an executor capacity for an estate, these sales are likely planned or administrative in nature rather than spontaneous insider moves—limiting how much they reveal about the director’s view of the company. For retail investors, purchases by insiders tend to be a clearer signal of confidence; sales can be routine (taxes, estate administration, pre-set plans).
