The filings describe grants, exercises and other transfers rather than trades on the open market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

The record was last updated on 2 October 2026 with a share grant in ASTROTECH Corp. Filings reach the SEC (Form 4) feed a median of 8 days after the trade. Section 16 rules allow two business days to file each Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
