Insiders At Materion Sold US$718k In Stock, Alluding To Potential Weakness

Materion Corporation (NYSE:MTRN) shareholders might have a reason to worry after multiple insiders sold their shares over the last year. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. However, shareholders should take a deeper look if several insiders are selling stock over a specific time period.

While insider transactions are not the most important thing when it comes to long-term investing, we would consider it foolish to ignore insider transactions altogether.

Materion Insider Transactions Over The Last Year

The VP, General Counsel & Secretary, Gregory Chemnitz, made the biggest insider sale in the last 12 months. That single transaction was for US$316k worth of shares at a price of US$105 each. That means that an insider was selling shares at slightly below the current price (US$126). As a general rule we consider it to be discouraging when insiders are selling below the current price, because it suggests they were happy with a lower valuation. Please do note, however, that sellers may have a variety of reasons for selling, so we don't know for sure what they think of the stock price. It is worth noting that this sale was only 16% of Gregory Chemnitz's holding.

Insiders in Materion didn't buy any shares in the last year. You can see the insider transactions (by companies and individuals) over the last year depicted in the chart below.

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. We usually like to see fairly high levels of insider ownership. Insiders own 1.1% of Materion shares, worth about US$29m. We've certainly seen higher levels of insider ownership elsewhere, but these holdings are enough to suggest alignment between insiders and the other shareholders.

So What Do The Materion Insider Transactions Indicate?

There haven't been any insider transactions in the last three months -- that doesn't mean much. Still, the insider transactions at Materion in the last 12 months are not very heartening. But it's good to see that insiders own shares in the company. While it's good to be aware of what's going on with the insider's ownership and transactions, we make sure to also consider what risks are facing a stock before making any investment decision. In terms of investment risks, we've identified 3 warning signs with Materion and understanding these should be part of your investment process.
