What Happened
Earl H. Nemser, Vice Chairman and Director of Interactive Brokers Group, sold a total of 245,000 shares in open-market transactions on January 22–23, 2026, for aggregate proceeds of roughly $18.97 million. The sales were: 100,000 shares at a weighted avg price of $76.81 ($7,681,000), 84,935 shares at a weighted avg $77.65 ($6,595,203), and 60,065 shares at a weighted avg $78.14 ($4,693,479).

• Footnotes: weighted-average prices reflect multiple trades within stated ranges; the reporting person has offered to provide a breakdown of shares sold at each price on request (F2–F4). F1 indicates indirect ownership via EN Holdings LLC.

Context

• Code S = Sale (disposition). Sales do not necessarily indicate negative views about the company; they can be for personal liquidity or other reasons.
• Ownership is at least partly indirect (EN Holdings LLC) and the filing also references restricted stock units, which can affect reported holdings.
• If you track insider activity, purchases usually carry more weight as potential bullish signals; sales are informative for monitoring insiders’ liquidity events.
