One of the patterns we like to see with insider buying is a long-serving Director of the company purchasing shares opportunistically. If that Director also happens to have an investing background, we like it even better. The cherry on the top is the company also buying back stock on the open market. We saw all these factors come together last week when Thomas Gayner purchased 5,000 shares of Cable One (NYSE:CABO) for Markel (MKL). Investors that follow Berkshire Hathaway and Fairfax Financial are also familiar with the third leg of the trinity of holding companies, Markel. This interview by Barry Ritholtz of Thomas Gayner on his Masters in Business podcast provides an excellent overview of Markel and its Chief Investment Officer and Co-CEO, Thomas Gayner. The little exchange they have about Mr. Gayner, as a 22 year old, discovering Berkshire when the stock was trading at around $375 and not buying it until the stock had gotten to $5,750 was amusing.

So, it was 1984, I was 22 years old, and I — I went into Joe’s office and I said, “Hey, Joe, have you ever heard of this guy named Warren Buffett.” And Joe was sort of a crusty fella, and he says, “It’s a Buffett, you idiot, and threw me out.”

Well, I went to the cutting-edge technology of the day, which was the Standard & Poor’s tear sheet.

And I — and I looked at the Berkshire Hathaway page. And my training is as an accountant. I started out as a CPA with PricewaterhouseCoopers. And I looked at those numbers, and I could tell without resorting to four decimal point calculations, they were good.

Mr. Gayner has served on Cable One’s board since 2015, when the company was spun out of Graham Holdings (GHC). He has also served on Graham Holdings’ board for over 15 years. Graham Holdings currently holds education services company Kaplan and a group of other diverse businesses after selling Washington Post to Jeff Bezos in 2013, two years before the Cable One spinoff. Getting back to Cable One, the company announced an additional $450 million share buyback program last month. The prior repurchase program established in 2015, still has $75.4 million remaining. It is interesting to see the company choose to buyback shares instead of paying down its considerable debt.

Despite declining nearly 26% year-to-date, the stock isn’t exactly cheap at the moment, trading at a forward P/E of 19 and a forward EV/EBITDA of 12. The company reported Q1 2022 earnings of $12.97 per share that beat analyst estimates by $1.66. Revenue of $426.73 million was up 25% year-over-year but down sequentially. Four analysts revised their earnings estimates higher during the last 90 days.

The rest of the top insider purchases this week were an odd bunch of companies including a development-stage oncology focused biotech, two companies that went public through SPACs and an electric car company. Each of them are down significantly this year and I covered the dismal performance of SPAC business combinations in a Twitter thread last week.

Welcome to edition 622 of Insider Weekends. Insider buying decreased last week with insiders purchasing $60.26 million of stock compared to $115.85 million in the week prior. Selling also declined to $802.51 million compared to $944.38 million in the week prior. For a second week in a row we saw a decline in both the number of insiders purchasing stock as well as a decline in absolute dollar terms.

Sell/Buy Ratio:

The insider Sell/Buy ratio is calculated by dividing the total insider sales in a given week by total insider purchases that week. The adjusted ratio for last week went up to 13.32. In other words, insiders sold more than 13 times as much stock as they purchased. The Sell/Buy ratio this week was unfavorable compared to the prior week when the ratio stood at 8.15.
