Stock Analysis

Shareholders May Not Overlook Mesa Laboratories Insiders Selling US$634k In Stock

Last week, Mesa Laboratories, Inc.'s (NASDAQ:MLAB) stock jumped 19%, but insiders who sold US$634k worth of stock in over the past year are likely to be in a better position. Selling at an average price of US$111, which is higher than the current price, may have been the best move for these insiders because their investment would have been worth less now than when they sold.

While insider transactions are not the most important thing when it comes to long-term investing, logic dictates you should pay some attention to whether insiders are buying or selling shares.

The Last 12 Months Of Insider Transactions At Mesa Laboratories

In the last twelve months, the biggest single sale by an insider was when the CEO, President & Director, Gary Owens, sold US$572k worth of shares at a price of US$114 per share. While we don't usually like to see insider selling, it's more concerning if the sales take place at a lower price. It's of some comfort that this sale was conducted at a price well above the current share price, which is US$73.14. So it is hard to draw any strong conclusion from it.

Does Mesa Laboratories Boast High Insider Ownership?

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. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Insiders own 3.0% of Mesa Laboratories shares, worth about US$11m. While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.
