Insider Buying Week 11-17-23 Few Buyers Lots of Sellers


 There are a few insider buys this week. As usual, there are a lot of sellers. 


Name: Roland D Diggelmann
Position: Director
Transaction Date: 2023-11-13  Shares Bought: 315 Average Price Paid: $1,026.54 Cost: $323,360

He is a Swiss citizen who serves on the Nomination and Compensation Committee of Sonova Holding AG.Mr. Diggelmann has over ten years of executive experience serving customers in the pharmaceutical/life science business, a critical end market for the company.

Opinion: Macro weakness, currency, and China issues are just some of the possible reasons for the dismal performance. Is this the turnaround signal we are looking for?  It’s a modest purchase by a knowledgeable director. I’d like to see more insiders buying this falling knife before I pull the trigger, though.


Name: James C Foster
Position: Chairman, President and CEO
Transaction Date: 2023-11-14  Shares Bought: 5,620 Average Price Paid: $178.05 Cost: $1,000,641

Opinion: The Gates Foundation owns nearly 5% of CRLThis is a good size purchase. More research is warranted.  I plan on listening to the quarterly earnings call. After selling millions of dollars worth of the stock since 2019, this is the CEO’s first purchase. Based on the recent stock performance, he might be embarrassed enough by his performance that he felt compelled to purchase some stock to placate unhappy shareholders. I would.

Opinion: Two sizeable purchases after a stock meltdown should put a temporary floor on the stock. Intuit’s Quickbooks Online could be an existential threat, but at some price, this strong billing competitor is a good buy.

Position: Chief Executive Officer
Transaction Date: 2023-11-10 Shares Bought: 4,453 Average Price Paid: $28.03 Cost: $124,818

Opinion: The CEO also purchased $250k worth of stock. Another mineral and royalty dividend play, BSM, also had insider buying this week.   The 11.9% current dividend yield looks interesting, considering that natural gas is at extremely low prices, and LNG export demand is expected to grow 25-50% in the 2024-2028 time range.

 You can be an insider, too– by clicking here

Insiders sell the stock for many reasons, but they generally buy for just one – to make money. You’ve always heard the best information is inside information.  Everyone with any stock market experience pays close attention to what insiders are doing.  After all, who knows a business better than the people running it?  Officers, directors, and 10% owners are required to inform the public through a Form 4 Filing of any transaction, buy, sell, exercise, or any other within 48 hours of doing so. This info is available for free from the SEC’s Web site, Edgar, although we subscribe to SECForm4  as they provide a way to manage and make sense of the vast realms of data. I’ve tried a lot of vendors. SECForm4 is one of the smaller ones, but I like supporting Frank. He is not arrogant. He’s helpful and has great prices. He also trades on his own data, so I like people that eat what they kill.

The bar is different from selling because the natural state of management is to be a seller. This is because most companies provide significant amounts of management compensation packages as stock and options. Therefore, we analyze unusual patterns with selling, such as insiders selling 25 percent or more of their holdings or multiple insiders selling near 52-week lows. Another red flag is large planned sale programs that start without warning. Unfortunately, the public information disclosure requirements about these programs, referred to as Rule 10b5-1, are horrendously poor. Also, planned sales that pop up out of nowhere are basically sales and are seeking cover under this corporate welfare loophole. I also generally ignore 10 percent shareholders as they tend to be OPM (other people’s money) and perhaps not the smart money on which we are trying to read the tea leaves. I say generally because some 10% shareholders are great investors. Think Warren  Buffett and others

Of course, insiders can also be wrong about their Company’s prospects. Don’t let anyone fool you into believing they never make mistakes.  Do your own analysis. They can easily be wrong, and in many cases, maybe most cases, have no more idea what the future may hold than you or me. In short, you can lose money following them.  We have, and we curse aloud; what were they thinking!

We like Fly on the Wall for keeping up with what events might be happening, analysts’ comments, and whatever else could be moving the stock.  Dow Jones news service is an essential tool, but many services pick up their feed like they do Bloomberg. For quick financial analysis, it’s hard to beat Old School Value.

A big callout to my assistant Ambreen who sets up this conversation by listing the notable buys that I’ve identified.  She probes the 10k for a reasonable description of the business. I’ve found that to be the most accurate and succinct place to find out what a business actually does.

This blog is solely for educational purposes and the author’s own amusement.  Think of the blog as part of my personal investment journal that I am willing to share with the DIY investor.  There are also many parts that I am not willing to share if I think it could influence trading action or be detrimental to the Fund’s partners. We could be long, short, or have no position at all in any of the stocks mentioned and express no written or implied obligation to disclose any of that.

The Insiders Fund is for qualified investors and by Prospectus only. Nothing herein should be construed otherwise.  THE INSIDERS FUND prefers to invest in companies at or near prices that management has been willing to invest significant amounts of their own money in, but we have no requirement to do so. We also invest in many companies in anticipation of future insider buying or with the expectation that there is none at all.
