Amkor Technology, Inc. (NASDAQ:AMKR) shareholders might have a reason to worry after multiple insiders sold their shares over the last year. When evaluating insider transactions, knowing whether insiders are buying is usually more beneficial than knowing whether they are selling, as the latter can be open to many interpretations. However, when multiple insiders sell stock over a specific duration, shareholders should take notice as that could possibly be a red flag.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, logic dictates you should pay some attention to whether insiders are buying or selling shares.

The Last 12 Months Of Insider Transactions At Amkor Technology

In the last twelve months, the biggest single sale by an insider was when the Lead Independent Director, Winston Churchill, sold US$431k worth of shares at a price of US$36.20 per share. We generally don't like to see insider selling, but the lower the sale price, the more it concerns us. The good news is that this large sale was at well above current price of US$29.37. So it is hard to draw any strong conclusion from it.

Does Amkor Technology Boast High 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. We usually like to see fairly high levels of insider ownership. Amkor Technology insiders own about US$1.5b worth of shares (which is 21% of the company). Most shareholders would be happy to see this sort of insider ownership, since it suggests that management incentives are well aligned with other shareholders.
