June 2026 Mailbag: “Do You Know Its Market Cap?”

**David Gardner** (0:00)
Should public companies report to their owners four times a year or just two?
That's not a theoretical question, it's a real proposal now being considered by the SEC. And this month, many a fool is taking the time to write the commission directly to explain why we believe transparency matters, and we have a great listener take on that coming up. Meanwhile, on this Mailbag, another listener asks when to add to a winning stock. Another shares a week so extraordinary that he does so anonymously, and another is a German police officer raising two daughters doing pretty much, I think, everything right, to the point that he asks, what creates the greatest opportunity for a meaningful and fulfilling life? Well, I'll try to answer a delightfully motley collection of notes, questions, stories and reflections from fellow fools around the world. It's the last Wednesday of the month, which means it is time for your Mailbag, only on this week's Rule Breaker Investing.

It's the Rule Breaker Investing Podcast with Motley Fool co-founder David Gardner.

Welcome back to Rule Breaker Investing. We had three earlier podcasts this month, three Wednesdays already. On June 3rd, I kicked off the month with I Fought the Law and the Law 1, Volume 3 where I brought back six more memorable laws, principles, mental models that help explain how our world works. We range from Sutton's Law this time and the Diderot Effect to Dunbar's Number, and even, yep, Gardner's Law, all in service of making us a little more aware of the patterns quietly shaping our lives. While I take some pride in always presenting new material, I want to admit an error that I made, and I fought the law and the law won, because I presented Sutton's Law, as I mentioned, which is basically, keep it simple, go where the money is, and I had forgotten I had already presented that on I Fought the Law and the Law 1, Volume 2, so we have a rare repeat of a point made, and I did so earlier this month without even remembering that the previous time I had already presented Sutton's Law. Anyway, mea culpa. Then on June 10th, we gathered around the campfire with Five Fellow Fools. It was Stock Stories, Volume 12, Time Travel Investing. That's a series, yeah, we've done it 12 times now because gathering around the campfire and telling stories is what humans have done for thousands of years. And in particular, this go-around, we connected around a surprisingly powerful theme, and that is that for great businesses, it is often not too late. We heard tales involving Google, IBM, Life 360, a biotech shell company that refused to die, and one fool just beginning his journey with individual stocks in his 50s, Stock Stories, Volume 12 And then last week, it was the Market Cap Game Show, the King Sharon Rule debuts. Charlie Travers and Jason Moser joined me and you for the 42nd installment of our long running game as we introduced our first major rule change in years. Along the way, we talked market caps, food delivery, spices, ski resorts, luxury cars, airplane parts, some more airplanes, some more cars. Somehow we learned a little bit more, not just about the stocks and the market caps, but how our world works as well. Through the lens of business. So that is the month that was, and I want to mention before I go into my Twitter ex hot takes for this Mailbag, that you can follow this podcast on Twitter ex at RBI podcast. And I'm at David G Fool. And I want to underline something because next week, it is our annual repeating what you've done to create financial freedom podcast. And because that is itself a Mailbag, that is listener driven. And we often with our Mailbags run a few weeks behind. I urge you to write me right away with something that you've done to enable financial freedom either for yourself, for family members or friends of the world at large over the past year. That's right here in the United States of America. We're celebrating our 250th anniversary as a nation. And every year on July 4th is Independence Day. And yet here on Rule Breaker Investing, we celebrate financial independence. And whether you have it yet or not, we're all seeking it. And I've always found it inspiring to hear from each of you what you have done to create financial freedom in the past year. So write us our email address is rbi at fool.com. You can again also tweet us on Twitter X at RBI podcast. What have you done to create financial freedom over the past year? All right. Now just a couple of Twitter X hot takes. Actually, the first one wasn't from Twitter. It was just from email, but it closed the loop on last month's Mailbags of Thayne Walton. Thank you for your note. You wrote, Hello, David. I told you I'm usually a week behind in my listening, but not this week. Got a text from a church buddy on Wednesday who declared, I'm famous. I immediately listened to Rule Breaker Investing. Again, this was last month's Mailbag. Always fun to hear a nice shout out. From the Motley Fool folks, you guys are great. I appreciate the one-sided friendship I feel as I listened to all of you. I then shared the episode with all my stock picking friends, and even my wife listened to it and came over and said, wow, he gave you a lot of time. Well, Thane, it wasn't hard to give you a lot of time. You're so welcome because it was a great note that you shared last month. So thanks for closing the loop. And then one other hot take, this one is from TwitterX at GaravK investor, Garav Kumar. You wrote in, reacting to last week's Market Cap Game Show. Love this. Come for the Market Cap Game Show, you tweeted and stay for the info on how cars work. And we did talk a lot about what happens under the hood last week's podcast. Part of the fun of putting the Market Cap Game Show together every quarter is randomizing which stocks will be covering and sometimes themes emerge of course randomly. And oh my gosh, cars and food last week. Well, it was a really fun Market Cap Game Show. Congratulations again to Jason Moser, who advances to this coming March's, March 2027 Market Cap Madness. All right, we've got seven Mailbag items this week.
