Sins of Omission vs. Commission in Investing

I had the pleasure of co-hosting another episode of Excess Returns with Matt Zeigler. We sat down with the one and only Tobias Carlisle — investor, author, podcast host, and all-around fascinating mind whose writing and ideas have influenced my thinking at various times.

He discusses his new book, which made me see Buffett’s investment approach in an entirely new light — and you’re about to discover why. I highly recommend both this episode and Toby’s book.

In this episode of Excess Returns, we sit down with Tobias Carlisle, founder and portfolio manager at the Acquirers Fund and author of the new book “Soldier of Fortune: Warren Buffett’s Sun Tzu and the Ancient Art of Risk Taking.”

Tobias joins Matt Zeigler and Bogumil Baranowski to explore how timeless strategic principles from The Art of War apply to investing and how Warren Buffett embodies many of those ideas—from invincibility and victory without conflict to the disciplined avoidance of ruin. The conversation connects Buffett’s real-world decisions—from Apple to General Re to Japan’s trading houses—to broader lessons on temperament, risk, and wisdom in markets.
