Materialise Insider Confidence Rewarded, Stock Hits US$336m Market Cap

Simply Wall St · 3d ago

Last week, Materialise NV (NASDAQ:MTLS) insiders, who had purchased shares in the previous 12 months were rewarded handsomely. The shares increased by 13% last week, resulting in a US$41m increase in the company's market worth, implying a 16% gain on their initial purchase. Put another way, the original €160.5k acquisition is now worth €186.3k.

Although we don't think shareholders should simply follow insider transactions, we do think it is perfectly logical to keep tabs on what insiders are doing.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

The Last 12 Months Of Insider Transactions At Materialise

In the last twelve months, the biggest single purchase by an insider was when Founder & Chairman Wilfried Vancraen bought US$80k worth of shares at a price of US$5.35 per share. Although we like to see insider buying, we note that this large purchase was at significantly below the recent price of US$6.21. While it does suggest insiders consider the stock undervalued at lower prices, this transaction doesn't tell us much about what they think of current prices.

Insider Ownership Of Materialise

I like to look at how many shares insiders own in a company, to help inform my view of how aligned they are with insiders. A high insider ownership often makes company leadership more mindful of shareholder interests. From our data, it seems that Materialise insiders own 2.0% of the company, worth about US$6.7m. We do note, however, it is possible insiders have an indirect interest through a private company or other corporate structure. Whilst better than nothing, we're not overly impressed by these holdings.

What Might The Insider Transactions At Materialise Tell Us?

It doesn't really mean much that no insider has traded Materialise shares in the last quarter. On a brighter note, the transactions over the last year are encouraging. We'd like to see bigger individual holdings. However, we don't see anything to make us think Materialise insiders are doubting the company. So these insider transactions can help us build a thesis about the stock, but it's also worthwhile knowing the risks facing this company.
