The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The latest filing, published on 17 December 2025, reports a transaction in Liberty Media Corp. Typically, a trade is published a median of 4 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
