“Rule Breaker Investing” Highlight Reel

We’re launching a new series—10 Years Later—where we open a time capsule, revisit a 5-Stock Sampler on its 10th birthday, and see what really happened. First up is our original (9/2/2015) sampler, 5 Stocks for the Next 5 Years: a motley mix that spanned Latin American e-commerce, rural convenience, blockbuster gaming, frontline cybersecurity, and kitchen-tech roll-ups. Longtime Fool Rick Munarriz joins as David’s sidekick to share the what, why, and when of these stocks’ march through the decade.

How did each of these stocks do? How about the sampler’s overall outperformance? David & Rick extract the key lessons. Rule Breaker Investing isn’t just about keeping score; it’s about learning how (and why) we win.

August 2025 Mailbag: Sports Bettor Turned Investor

To close out the 2025 Authors in August series, we flip the script—and the mic. Chris Hill, longtime Fool and creator of Motley Fool Money (and host of Money Unplugged) returns as guest host to grill David about his forthcoming book, “Rule Breaker Investing.”

David reveals his first-ever Rule Breaker stock (before he’d even coined the phrase), the inspiration for his discipline… he names names on current dark clouds investors may be able to see through, and brings Rule Breaker thinking across diverse topics, from portfolio construction to sports betting.

Finally, it’s Chris who leads a round of Buy, Sell, or Hold, with David!

Authors in August: “Rule Breaker Investing” with David Gardner & Chris Hill

Continuing our eighth annual Authors in August series, David welcomes Sam Horn, renowned communications strategist and founder and CEO of the Intrigue Agency, based in Austin, Texas. Sam gamely plays a little book roulette. She starts by detailing how to nail a sixty-second pitch, then walks us through how to handle rude people, blamers, shamers, complainers, non-stop talkers, people who refuse to cooperate, and those who ignore rules or boundaries. 

They also reveal the word that David is trying his best to avoid saying, and finish with a raucous round of Buy, Sell, or Hold.
