Thematic Investing in Practice using Industry and Supply Chain Mapping
Identifying stocks best placed to win across a thematic or industry value chain
Hi, its Andy West. This week, we’re focusing on an exciting topic - thematic investing and how you can put it into practice using our tools. Below there’s a fascinating freebie for you - a complete 65 page thematic report into the Humanoid Robotic Industry create with Inferential Investor IP.
The allure of a grand theme has always tempted the investor’s imagination: Electric vehicles, artificial intelligence, renewable energy, quantum computing. Each represents progress, possibility, and potential profit. Yet behind every theme lies an important question: Which companies will ultimately win and produce the best returns?
To answer this entails detailed investigations of an ecosystem of manufacturers, suppliers, production lines, and balance sheets which can be an incredibly daunting task. The implicit realization is that some firms will capture and accumulate the wealth such revolutions create, while others will merely pass it through. How does an investor solve this puzzle? How much time does it take to piece together a confident picture of the value chain, relative economics and likely winners?
To research and invest wisely in a theme is to understand not only the vision but also the industry participants that enable it and to distinguish where the growth and economics reside at different stages of the theme’s evolution. The prudent investor starts this process by mapping it in detail. The Inferential Investor’s Thematic, Industry and Supply Chain Prompt has just exited testing and optimization and has been added to the Professional Prompt Library for paid subs. This has been engineered to address each of the considerations discussed in this article and present the investor with detailed insights on a reasoned short-list of potentially best placed stocks within a thematic.
As tangible proof of what this prompt can do, I’ve attached here for free, a downloadable 65 page PDF primer on the exciting Humanoid Robotics Industry. With many OEMs like Tesla moving now to prototype plants and potential IPOs of some players on the horizon, this report presents a gold mine of information on those companies exposed. The insights here, gained early in a theme’s evolution, pay for multiple annual subscriptions alone.

The Nature of Thematic Investing
Thematic investing begins with a premise: that a structural change in technology, policy, or society will reshape industries and capital flows. It offers the chance to participate in the evolution of entire sectors rather than single firms. But themes can be abstract; they describe direction without detail as to economics or timeframe. Investors are drawn to them because they promise compounding growth but the risk is imagination can outpace real world practicalities that control returns.
The discipline lies in distinguishing the theme from the industry dynamics. A theme describes what is changing; the industry dynamics dictate how it changes, how long it takes, who enables it, and who profits from it. Each theme manifests as a web of firms, technologies, and supply dependencies. To understand and map these relationships is to start to see where value may accumulate as adoption scales. Themes themselves cannot be owned even if investors often attempt this with overly diversified thematic ETFs; only the businesses that turn them into earnings can.
Mapping the Industry
Every transformative idea eventually coalesces into an industry with definable inputs, players, processes, constraints and outputs. The investor’s first task is to draw this map - to trace the movement and transformation of capital and materials from raw resources and intellectual property, to finished product and the customer.
An industry typically divides into three layers: upstream suppliers that provide critical materials or technologies; midstream manufacturers that assemble or process them; and downstream players that deliver products to end users. The economic balance and competition among these layers determines who earns and who subsidizes. In many themes, the quiet enablers, that is, firms selling key components or production tools, capture better margins at early stages than the celebrated brand names, provided they have protected IP.
Think of OpenAI and NVIDIA in the artificial intelligence theme. OpenAI developed the scalable decoder-only architecture that led to the ChatGPT-3 breakthrough launch in 2022. While its value has gone from zero to an estimated $500bn, at the same time, NVIDIA, as the primary enabler (the picks and shovels of AI) has added trillions of dollars in value. Why? OpenAI’s generative AI models have significant competition, are hugely capital intensive and being progressively commoditized. NVIDIA’s IP however has so far proven a critical enabler, with limited competition facilitating pricing power, huge margins and relatively low capital intensity. The value economics have so far accrued to them.
By mapping the structure, one can observe barriers to entry, switching costs, pricing power, potential margins and capital intensity. The layers that combine technological uniqueness with customer dependence tend to hold pricing power; those defined by commoditized competition tend not to. Industry mapping helps surface these asymmetries and replaces thematic shotgun diversification with targeted hunting.
The Supply Chain as Microscope
The supply chain is the investor’s microscope. Its strategic research can reveal the hidden dependencies beneath the narrative. Each product can be decomposed into its bill of materials - what goes into it, who supplies each part, and how costs behave as volume grows.
New technologies begin with fragile supply chains. Inputs are costly, suppliers scarce, and production inefficient. As industries scale, costs fall, but the decline is uneven. Some components commoditize rapidly; some get in-sourced but others remain scarce and profitable. Electric Vehicle manufacturers have now fared better than Lithium miners in the EV thematic, whereas that was not the case early on in the thematic. Both are part of the same industry chain and experiencing growing demand overall, but rapid capacity additions in lithium supply destroyed the economics of that part of the value chain, even as costs reduced for EV manufacturers and volumes scaled to make them profitable.
Studying the supply chain allows the investor to locate these choke points and how they are evolving over the life of a thematic. The questions are simple yet revealing: Which components determine capacity? Which suppliers possess proprietary processes? Where will cost declines erode margins, and where will scale enhance them?
Capital, Competition, and Value Capture
Themes can attract torrents of capital: venture funding, IPOs, subsidies, and speculative flows. But abundance of funding does not in the end ensure durability of profit. Indeed, when money is cheap and plentiful, capital-intensive industries often multiply unprofitably (sound familiar?). The wise investor studies not just where goods flow, but where money pools, and which firms can sustain themselves when that tide recedes.
True value creation occurs where innovation meets scarcity and long term value capture is retained where pricing power persists. A company may advance a technology yet fail to retain the economic rewards if its product quickly becomes interchangeable or it does not protect the IP such that it can be replicated in house by an OEM. The objective is to identify the businesses that possess differentiation, IP protection, switching costs, and capital efficiency. These are structural features that allow them to outlast early narrative enthusiasm.
History offers many reminders: solar panel manufacturers struggled under relentless competition, while suppliers of specialized materials and equipment earned steady returns. The glamour of the final product is not necessarily the predictor of where the profits ultimately reside.
Timing the Theme
Even when the structural winners are clear, timing matters. Early in a theme’s development, upstream suppliers often benefit first as demand for components surges (eg Lithium miners early in the EV theme). Later, once processes stabilize and capacity scarcity is addressed, downstream brands may gain as costs normalize. Each stage of the chain experiences its own cycle of optimism and consolidation, often at different stages.
Understanding these sequences prevents premature investment in unprofitable layers of the chain. Within the AI revolution, NVIDIA as the gatekeeper of the core processing technology surged early, while memory manufacturers lagged. In 2025, that leadership has reversed as incremental growth in GPUs decelerates, but the memory cycle turned, as demand surged on inference loads and data center additions, while excess supply was finally absorbed. A correct theme expressed in the wrong names at the wrong time, is no better than a wrong one. Patience and stage awareness transform thematic enthusiasm into strategy.
Thematic Investing in Practice: Industry and Supply Chain Mapping with The Inferential Investor
To convert these principles into a practical research method, a comprehensive Industry and Supply Chain Mapping Prompt is provided in the prompt library:
This is a structured framework designed to dissect an entire sector from top to bottom and pinpoint interesting choke points and companies.
It begins by examining the history, maturity, and technological direction of an industry or theme: what problems it solves, how it evolved, the challenges it has already faced and which forces - scientific, regulatory, or economic - drive its expansion. The investment research workflow expressed in the prompt then triangulates market projections from multiple credible sources to form a balanced view of market size, growth, timeframes, and competitive landscape.
It identifies and profiles the key players, brand owners, OEMs or other leaders in the industry and synthesizes from press releases, interviews, news, presentations through to stock write-ups, the respective company’s ambitions in the theme, funding raised, their key personnel, milestones achieved, leader or follower status, key competitors, timeframe to commercialization, partnerships and suppliers.
Next, it dissects the main product categories and their functions. Each product is broken where it can into its bill of materials, identifying major component areas and their respective purposes. This granular breakdown clarifies which inputs dominate costs, how these costs are expected to decline with scale, and where substitution or technological improvement might shift margins.
The prompt then extends into supply chain mapping, tracing upstream to find the suppliers of those key components. Each supplier is profiled for its level of exposure to the theme, its competitive position, and whether its margins may expand or compress as adoption grows. Public or private status, geographic footprint, and recent strategic moves are all documented. The outcome is a top-down visualization of how value flows through the industry, from raw materials to end-product and which firms stand at the points of leverage.
By following this logic, investors move from narrative to evidence and potential actions. They see how an exciting idea becomes gradually tangible for the investor. In practice, this method transforms thematic investing from guesswork or a shotgun approach, into an organized study of production economics. It helps investors distinguish between the firms promoting the theme and those profiting from it.
The outcome of the Inferential Investor research workflow is a well structured and detailed report on an industry and its supply chain, technologies, products, economics and most interesting opportunities. The investor can then delve deeper into each short-listed company using additional copy/paste research workflows in the library (such as earnings analysis reports, stock initiation reports, transcript summaries and analysis, news impact reports, red flag reports, consensus forecast checks etc), to round out a full assessment of the investment attractiveness of that stock. In other words, the prompt library allows you to perform an entire investment process that would previously have taken weeks, in your spare weekend hours.
Closing Reflections
Thematic investing, pursued with structure and process, can be rewarding and engaging. It is the careful study of how innovation reorganizes economic relationships and transforms our lives. By using the tools we provide and grounding analysis in industry and supply chain mapping at the start, the inferential investor gains the perspective to see beyond just the surface excitement to the deeper and far more tangible architecture of value creation and associated winners and losers.
As always,
Inference never stops. Neither should you.

The Inferential Investor
This is genuinely one of the most valuable frameworks for thematic investing I've encountered - institutional-grade methodology made accessible. Your distinction between themes describing 'what is changing' versus industry dynamics dictating 'how it changes, how long it takes, who enables it, and who profits' cuts to the core challenge most thematic investors miss. The OpenAI vs NVIDIA comparison crystallizes this perfectly: OpenAI added $500B in value but NVIDIA added trillions because GPUs remained a critical, defensible enabler while generative AI models became capital-intensive and commoditized. The supply chain microscope approach is brilliant - decomposing products into bill of materials to locate choke points that persist as industries scale. Your EV example showing manufacturers outperforming lithium miners after initial capacity surges destroyed mining economics demonstrates how rapidly competitive dynamics can shift even within a single value chain. The observation that early-stage upstream suppliers often benefit first (eg NVIDIA in AI, lithium miners early in EVs) while downstream brands gain later as processes stabilize and costs normalize is the timing insight that separates thoughtful positioning from thematic enthusiasm. What resonates most is the philosophical discipline: 'True value creation occurs where innovation meets scarcity and long term value capture is retained where pricing power persists.' This is the filter that distinguishes sustaniable compounders from narrative-driven speculation. The 65-page Humanoid Robotics report demonstrating practical application of your prompts library methodology is exceptional value delivery.
