We've lost count of how many times insiders have accumulated shares in a company that goes on to improve markedly. On the other hand, we'd be remiss not to mention that insider sales have been known to precede tough periods for a business. So before you buy or sell Atrion Corporation (NASDAQ:ATRI), you may well want to know whether insiders have been buying or selling.

Do Insider Transactions Matter?

It's quite normal to see company insiders, such as board members, trading in company stock, from time to time. However, most countries require that the company discloses such transactions to the market.

We don't think shareholders should simply follow insider transactions. But it is perfectly logical to keep tabs on what insiders are doing. 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'.

Atrion Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider purchase was by Independent Director Preston Athey for US$66k worth of shares, at about US$661 per share. So it's clear an insider wanted to buy, at around the current price, which is US$667. Of course they may have changed their mind. But this suggests they are optimistic. If someone buys shares at well below current prices, it's a good sign on balance, but keep in mind they may no longer see value. In this case we're pleased to report that the insider bought shares at close to current prices. Preston Athey was the only individual insider to buy during the last year.

Does Atrion Boast High Insider Ownership?

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Atrion insiders own 16% of the company, currently worth about US$191m based on the recent share price. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.
