This Insider Has Just Sold Shares In Alphatec Holdings

We wouldn't blame Alphatec Holdings, Inc. (NASDAQ:ATEC) shareholders if they were a little worried about the fact that Mortimer Berkowitz, the Independent Lead Director recently netted about US$998k selling shares at an average price of US$15.97. However, it's crucial to note that they remain very much invested in the stock and that sale only reduced their holding by 4.9%.

Insider Ownership

I like to look at how many shares insiders own in a company, to help inform my view of how aligned they are with insiders. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Alphatec Holdings insiders own 9.6% of the company, currently worth about US$216m based on the recent share price. Most shareholders would be happy to see this sort of insider ownership, since it suggests that management incentives are well aligned with other shareholders.
