How oil becomes plastics, where a company's margins actually come from, and why some industries concentrate into a handful of players while others don't.
Understanding how companies, industries, and supply chains actually work — and how they connect.
These articles trace real systems. How raw materials move through supply chains and where bottlenecks form. How a company generates revenue, what makes its position durable, and where its structural vulnerabilities sit. How financial patterns emerge from physical constraints, capital flows, and the coordination problems that every industry solves differently.
The topics range from individual company mechanics to industry-wide observations — and they connect. A supply chain article about semiconductors links to the business models that depend on it. An investment concept like capital allocation connects to the patterns visible in the screener. The articles form a network, not a list — follow one thread and it leads to others.
Supply Chains
A supply chain is the full path that materials, components, and products travel from their origin to their end use — crossing organizational, geographic, and regulatory boundaries at each stage.
Screener Guides
Practical guides for using the screener to explore structural patterns — what each diagnostic identifies, how to interpret the results, and what the screener can and cannot tell you.
How to Analyze a Company
The foundational dimensions the screener measures — profitability, growth, leverage, liquidity, and more — explained as structural properties of a business, not just numbers on a spreadsheet.
Pattern Stories
Structural narratives of individual companies — how their systems evolved over time, what patterns shaped them, and what their current structure reveals about constraints and dependencies.
Investment Concepts
Structural concepts that describe how businesses, industries, and financial patterns work — the vocabulary for understanding what financial data reveals about underlying reality.
Business Models
A business model describes how a company creates revenue, manages costs, and sustains itself over time — the structural mechanics that determine whether a business works, not whether its stock price moves.
Investor Profiles
How notable investors think about markets, risk, and value — not as advice to follow, but as distinct frameworks for understanding how different structural assumptions lead to different investment approaches.
