Some Madrigal Pharmaceuticals, Inc. (NASDAQ:MDGL) shareholders may be a little concerned to see that the CEO, President & Director, William Sibold, recently sold a substantial US$3.2m worth of stock at a price of US$446 per share. That's a big disposal, and it decreased their holding size by 12%, which is notable but not too bad.

Insider Ownership

Looking at the total insider shareholdings in a company can help to inform your view of whether they are well aligned with common shareholders. I reckon it's a good sign if insiders own a significant number of shares in the company. Madrigal Pharmaceuticals insiders own about US$1.1b worth of shares (which is 11% of the company). This kind of significant ownership by insiders does generally increase the chance that the company is run in the interest of all shareholders.
