This Form 144 is routine and immaterial. No trading action warranted based on this filing alone. Monitor for any future Form 4 filings if the sale is completed, but the amount is too small to carry a signal about insider sentiment.
Price Chart
Executive Summary
Former director Thomas G. Wiggans filed a Form 144 notice of intent to sell 1,000 common shares of Annexon (ANNX) with an approximate market value of $5,605. The shares were acquired via stock option exercise on the same filing date. This is a de minimis sale relative to Wiggans' likely holdings and the company's ~$922M market cap, and he is a former director (no longer insider for insider-trading purposes). The filing carries no material information and is not indicative of any change in business fundamentals or outlook.
Key Facts
