We do like to see buying, but this purchase was made at well below the current price of US$2.11. Because it occurred at a lower valuation, it doesn't tell us much about whether insiders might find today's price attractive.

Does Biodesix Boast High Insider Ownership?

For a common shareholder, it is worth checking how many shares are held by company insiders. I reckon it's a good sign if insiders own a significant number of shares in the company. Biodesix insiders own 74% of the company, currently worth about US$142m based on the recent share price. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.
