Stock Analysis

Non-Executive Director of CML Microsystems Nathan Zommer Buys 81% More Shares

Those following along with CML Microsystems plc (LON:CML) will no doubt be intrigued by the recent purchase of shares by Nathan Zommer, Non-Executive Director of the company, who spent a stonking UK£1.5m on stock at an average price of UK£2.62. That purchase boosted their holding by 81%, which makes us wonder if the move was inspired by quietly confident deeply-felt optimism.

CML Microsystems Insider Transactions Over The Last Year

In fact, the recent purchase by Nathan Zommer was the biggest purchase of CML Microsystems shares made by an insider individual in the last twelve months, according to our records. Although we like to see insider buying, we note that this large purchase was at significantly below the recent price of UK£3.20. Because it occurred at a lower valuation, it doesn't tell us much about whether insiders might find today's price attractive.

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. I reckon it's a good sign if insiders own a significant number of shares in the company. It appears that CML Microsystems insiders own 36% of the company, worth about UK£18m. While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.

What Might The Insider Transactions At CML Microsystems Tell Us?

It's certainly positive to see the recent insider purchases. And the longer term insider transactions also give us confidence. But on the other hand, the company made a loss during the last year, which makes us a little cautious. Insiders likely see value in CML Microsystems shares, given these transactions (along with notable insider ownership of 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. Every company has risks, and we've spotted 2 warning signs for CML Microsystems (of which 1 is concerning!) you should know about.
