Summary

On today’s episode, Kyle Grieve discusses powerful mental models from systems thinking and mathematics and applies them directly to investing and life. He breaks down concepts like feedback loops, kill criteria, scale, compounding, randomness, and regression to the mean to show how they shape real-world outcomes. He'll also share practical frameworks for improving decision-making, managing uncertainty, and positioning your portfolio to benefit from long-term compounding. IN THIS EPISODE YOU’LL LEARN: 00:00:00 - Intro 00:03:23 - How feedback loops stabilize or reinforce outcomes in investing 00:10:11 - How kill criteria help you make predetermined decisions in a noisy world 00:14:09 - Why the cone of uncertainty is useful for evaluating conviction and position sizing 00:17:33 - How scale changes the behavior, costs, and risks of a growing business 00:25:06 - How algorithms clarify which inputs drive the conclusions you rely on 00:30:20 - How to evaluate a company’s ability to reach critical mass and become self-sustaining 00:35:35 - The hidden forms of compounding that are just as powerful as the visible ones 00:40:02 - Why power laws should influence your portfolio concentration 00:43:12 - How randomness shapes investing outcomes, and how to take advantage of it 00:51:24 - Why regression to the mean matters during periods of strong or weak performance Disclaimer: Slight discrepancies in the timestamps may occur due to podcast platform differences.

0:00.0	You're listening to TIP.
0:02.0	Did you know that over long periods, just a handful of stocks will account for the vast
0:07.0	majority of a portfolio's return?
0:09.0	And that's even if half of your investments fail, the winners can still make up for the losses,
0:14.0	and then some.
0:15.0	Now, that asymmetry results from power laws and convex compounding.
0:19.0	And once you truly understand how these mathematical forces work inside of real-world systems,
0:24.7	it will completely change the way that you think about investing.
0:27.7	In today's episode, we're exploring the metal models from systems thinking
0:31.3	and mathematics that have had the biggest impact on my own personal investing approach.
0:36.0	We'll look at things such as feedback loops, kill criteria,
0:39.0	and the cone of uncertainty, and how these systems can be used to improve your thinking process.
0:43.4	We'll examine how scale changes a business as it grows, how algorithms help you make more certain
0:48.5	decisions, and how critical mass can propel a company into beneficial self-sustaining mode.
0:54.0	Then we'll shift over to the mathematical side of things, and don't worry, you won't need
0:57.7	to pull out a calculator to follow along.
1:00.0	We'll look at concepts like in compounding, power laws, randomness, and regression to the
1:04.5	mean, and then we'll tie them all together so you can really understand just how these
1:08.4	forces quietly shape your portfolio's long-term performance.
1:12.6	This episode is for investors who want to think more clearly, whether you're trying to expand
1:16.1	your mental toolbox, aiming to avoid common pitfalls, or looking for new ways to stress test
1:21.5	your own reasoning. If you're someone who really values long-term thinking, likes understanding
