Roots and Branches

An epistemological framework for investing developed by Nima Shayegh (Rumi Capital Partners) in a 2023 speech at Columbia University, later a shareholder letter. The framework distinguishes between the visible surface of a business (branches) and the qualitative causal forces that determine its future (roots).

Branches — quantifiable surface metrics: last quarter’s margins, unit growth rates, credit card spending data, web-scraped revenue proxies, inflation prints. Visible, precise, and widely available. Branches describe the present state of a business.

Roots — qualitative forces causally upstream of economics: management motivation, company culture, product quality, customer alignment. Not quantifiable, not in any spreadsheet. Roots determine the future economics of a business.

The diagnostic: almost no investor compounds capital at very high rates for long, despite the proliferation of expert calls, algorithmic data, and PhD computer scientists. Shayegh’s explanation — the industry has swung toward branches while roots remain largely uncontested territory, because accessing roots requires intuition rather than tools.

The foundational principle, from Lou Simpson: “All investing is figuring out the future economics of a business.”

The perception problem

Why does everyone not focus on roots? Because roots require qualitative perception — pre-intellectual awareness that is subjective and hard to communicate in a research report or investment committee presentation. This creates both a difficulty and an opportunity.

The Persian concept of cheshm del (“eye of the heart”) — a thousand-year-old formulation — captures what is required: a faculty of perception capable of grasping non-material truths. Trustworthiness, sincerity, ambition, and beauty cannot be modelled, but they can be directly perceived. Robert Pirsig’s pre-intellectual cutting edge of reality is a parallel formulation from a Western philosophical tradition.

Shayegh argues that every human has this perceptual capacity. It is not a superpower to develop but a natural capability to uncover by removing what blocks it. What blocks it is the ego.

Ego as the distorter

The ego operates from fear and self-preservation. It creates:

Institutional bias: “I can’t own that stock because it will make fundraising harder.”
Inability to admit error: holding a losing position rather than acknowledging a mistake.
Illusion of control: the belief that one more spreadsheet row brings you closer to reality.

These ego-driven decisions systematically produce bad investment outcomes because they distort perception of the roots. Emotion, by contrast, is not the distorter — it is often a signal. Becoming more impressed with a business over years of ownership is a meaningful data point.

“Blowness” — Shayegh’s informal label for the physiological quality signal: the experience of encountering something clearly extraordinary (Tesla’s full self-driving navigating a car park; the first iPhone; Amazon same-day delivery). The experience is emotional and physiological, not quantifiable, but it is repeatable and diagnostically reliable.

The roots of a great business

Shayegh’s application of the roots framework to specific investment cases:

Appfolio (property management SaaS): roots are partnership culture (never extracts excess rent from customers), sits at the centre of all workflows (deep stickiness), non-promotional (no Q&A on earnings calls — frustrating to Wall Street but a root quality). Result: over 30% compound annual return over ten years, mostly misunderstood.

Costco (via Charlie Munger): in markets where Sam’s Club was opening stores directly across the street, Costco cut its own prices. A surface analyst doing channel checks saw no pricing power and wrote a sell note. Munger, focused on roots — “product quality improving, management ethical, culture meritocratic” — held through a full decade of flat stock price (2000–2010).

Brookfield: management invests billions of personal capital alongside LP capital. Alignment is a root quality — it can be mimicked through structural incentives but the real version is perceived rather than contractually guaranteed.

Connection to qualitative value investing

The roots and branches distinction is a systematic account of what Howard Marks calls “feel” and what Andrew Marks formulates as: widely available quantitative information on the present is unlikely to be the source of superior profits. See Value Investing §Market efficiency and the shrinking edge.

Brad Stulberg’s Involved Engagement concept converges on the same epistemology from a different direction: Pirsig’s Quality is pre-intellectual, present before intellectual analysis begins, the thing Steph Curry’s jump shot and Rothko’s canvases share. Both frameworks point to a mode of perception that bypasses the ego-driven analytical machinery.

Where mainstream views differ

Quantitative investing: Systematic strategies (factor models, algorithmic screening) hold that the roots Shayegh describes are either priced by the market or unmeasurable with enough reliability to systematically exploit. The consistent outperformance of great concentrated investors is attributed to luck (survivorship bias) rather than qualitative perception.

Due diligence as process: Institutional investment practice places qualitative judgments inside structured processes (management interviews, reference checks, scoring rubrics) specifically to reduce the role of individual perception — on the ground that individual perception is unreliable and ego-prone. Shayegh inverts this: the process itself becomes the ego structure that blocks clear perception.

Pre-intellectual awareness as non-transferable: Even if qualitative perception is valid, it may not be teachable or scalable. Simpson could transmit it by example to one apprentice; it may not be the basis of a repeatable institutional process.
