In the last year, many Amkor Technology, Inc. (NASDAQ:AMKR) insiders sold a substantial stake in the company which may have sparked shareholders' attention. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. 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, we would consider it foolish to ignore insider transactions altogether.

Amkor Technology Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the insider, John Kim, sold US$49m worth of shares at a price of US$25.28 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$33.27. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. However, while insider selling is sometimes discouraging, it's only a weak signal. This single sale was just 10% of John Kim's stake.
