Quite a few Zynex, Inc. (NASDAQ:ZYXI) insiders sold their shares over the past year, which may be a cause for concern. 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 do think it is perfectly logical to keep tabs on what insiders are doing.

Check out our latest analysis for Zynex

Zynex Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Chief Financial Officer, Daniel Moorhead, sold US$170k worth of shares at a price of US$8.49 per share. That means that even when the share price was below the current price of US$8.89, an insider wanted to cash in some shares. 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. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. This single sale was just 44% of Daniel Moorhead's stake.
