Should You Be Worried About Insider Transactions At Quidel Corporation (NASDAQ:QDEL)?

Simply Wall St

We've lost count of how many times insiders have accumulated shares in a company that goes on to improve markedly. The flip side of that is that there are more than a few examples of insiders dumping stock prior to a period of weak performance. So shareholders might well want to know whether insiders have been buying or selling shares in Quidel Corporation (NASDAQ:QDEL).

Do Insider Transactions Matter?

It is perfectly legal for company insiders, including board members, to buy and sell stock in a company. However, such insiders must disclose their trading activities, and not trade on inside information.

We don't think shareholders should simply follow insider transactions. But equally, we would consider it foolish to ignore insider transactions altogether. As Peter Lynch said, 'insiders might sell their shares for any number of reasons, but they buy them for only one: they think the price will rise.

Quidel Insiders Are Selling The Stock

The last quarter saw substantial insider selling of Quidel shares. Specifically, Senior Vice President of Information Systems & Business Transformation Karen Gibson ditched US$306k worth of shares in that time, and we didn't record any purchases whatsoever. This may suggest that some insiders think that the shares are not cheap.

Insider Ownership of Quidel

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. I reckon it's a good sign if insiders own a significant number of shares in the company. It's great to see that Quidel insiders own 9.0% of the company, worth about US$209m. This kind of significant ownership by insiders does generally increase the chance that the company is run in the interest of all shareholders.

So What Does This Data Suggest About Quidel Insiders?
