Redefining the Innovation Economy: Why Traditional Industry Classifications No Longer Work
Introduction: The Yardstick Problem
The tools we use to measure the economy can blind us to its transformation. For decades, investors, analysts, and policymakers have relied on the Morningstar Global Equity Classification System—a framework designed for an era of factories, smokestacks, and raw materials—to group public companies into tidy sectors like “Industrials,” “Consumer Cyclical,” and “Basic Materials.” Yet as the business landscape tilts toward technology-driven industries, this industrial-era yardstick increasingly distorts what it claims to measure.
The core thesis is straightforward: as the innovation economy advances—driven by technology, intellectual property, and knowledge-based industries—traditional industry labels become not just imprecise but actively misleading. A company that generates most of its value from software, network effects, and data cannot be accurately compared to one that manufactures physical goods, even if both appear in the same sector. This mismatch creates blind spots for portfolio construction, valuation, and even macroeconomic policy.
In response to this growing disconnect, a November 2023 report from Morningstar and PitchBook introduced the Morningstar PitchBook Global Unicorn Industry Vertical Indexes. These indexes aim to provide a new classification lens—one rooted in emerging technology research rather than legacy industry silos. They represent a recognition that the innovation economy demands fresh tools, and that clinging to old ones risks missing the most significant sources of growth.

The Mismatch: Why Traditional Classifications Fail Innovation
“Traditional industry groups that are used to classify securities still largely reflect the foundations of the industrial economy,” the report states, highlighting a fundamental friction. Consider Tesla: a company that has redefined the automotive sector while simultaneously functioning as an energy storage firm, a software platform, and a data company. Under most legacy classification systems, Tesla sits squarely in “Automakers,” alongside Ford and General Motors. This grouping obscures the fact that Tesla’s competitive edge lies in its integrated software stack, battery technology, and autonomous driving algorithms—attributes that align more closely with the technology sector than with traditional manufacturing.
The Morningstar Global Equity Classification System, a widely used framework, categorizes companies primarily by the products they sell. Yet in the innovation economy, the most valuable firms often defy product-based categorization. Amazon is classified as a retailer, but its profit engine is cloud computing and advertising. Alphabet is classified as a media company, yet its core asset is search algorithms and artificial intelligence. Such classifications create peer groups that share little in terms of business models, growth drivers, or risk profiles.
The hidden economic logic behind this mismatch runs deeper. Industrial-era classifications assume linear supply chains, stable input costs, and predictable geographic boundaries. A steel company buys iron ore, produces steel, and sells it to automakers or construction firms. Its value chain is straightforward. Innovation-economy firms, by contrast, thrive on non-linear, platform-based value creation. Their inputs are data, code, and intellectual property; their outputs often exhibit network effects, where each new user increases the value for all others. Consider a fintech unicorn that connects lenders, borrowers, and payment processors—it is simultaneously a software company, a financial intermediary, and a data analytics firm. No single industrial category captures this cross-sector disruption.
Evidence of this mismatch is visible in index composition. As the economy tilts further toward technology-driven industries, legacy indexes may underweight disruptive firms or misrepresent their genuine peer groups. For example, many “Consumer Cyclical” companies today derive significant revenue from subscription models, advertising, and digital services—attributes traditionally associated with technology. Yet they remain grouped with apparel retailers and auto parts manufacturers, diluting the index’s ability to reflect economic reality.

The New Yardstick: Morningstar PitchBook Global Unicorn Indexes
Against this backdrop, the Morningstar PitchBook Global Unicorn Industry Vertical Indexes offer a fundamentally different approach. These indexes are based on a new industry classification system that stems from PitchBook’s emerging technology research, which has tracked private market innovation for years. Rather than grouping companies by product category, they target “unicorn” companies—private or public—that define the innovation economy: firms valued at $1 billion or more, with business models rooted in technology, intellectual property, and knowledge-based assets.
“The new economy is characterized by the advancement of technology, intellectual property, and a focus on knowledge-based industries,” the report notes. The indexes cover 27 industry verticals, ranging from artificial intelligence and fintech to health tech, clean tech, and cybersecurity. What sets them apart is their integration of private and public markets—a critical feature in an era where many high-growth innovation companies remain private for longer than ever before. Historically, classification systems have been designed exclusively for public equities, ignoring the vast and growing universe of unicorns that have not yet IPO’d. The new indexes close this gap, offering a holistic view of the innovation landscape.
For example, the AI vertical includes companies developing machine learning platforms, natural language processing tools, and autonomous systems—whether they are listed on major exchanges or still in private hands. The fintech vertical spans digital payments, lending platforms, and blockchain-based services, recognizing that these firms compete on technology rather than on traditional banking metrics. By creating a taxonomy built on technological capabilities rather than end-product categories, the indexes better capture the cross-sector nature of innovation.
This framework also addresses a long-standing critique of legacy classifications: their inability to evolve with the pace of technological change. The PitchBook taxonomy is regularly updated based on emerging technology trends, meaning that a new vertical (say, “generative AI” or “quantum computing”) can be added as it gains commercial relevance. In contrast, traditional industry codes are revised on multi-year cycles, often lagging behind market reality by a decade or more.

Why This Shift Matters for Investors, Valuations, and Policy
The implications of adopting a new classification lens extend far beyond academic debates about index construction. For investors, transparent and accurate industry grouping is essential for identifying growth opportunities, managing portfolio concentration, and performing peer-relative analysis. If a portfolio manager believes they have sufficient exposure to “technology” but their classification system hides tech-enabled companies under “industrials” or “financials,” they may inadvertently underweight the innovation economy. The new indexes allow investors to deliberately allocate capital to specific verticals—such as “health tech” or “clean tech”—without the noise of generic sector labels.
Valuation models also need to evolve. Traditional valuation frameworks often rely on comparable company analysis within the same GICS or ICB sector. But when a software-enabled healthcare company is grouped with hospital operators, the peer set becomes meaningless. The unicorn vertical indexes provide a more relevant peer universe: companies that share similar revenue models (e.g., platform-based, software-as-a-service), similar intangibles (patents, data moats), and similar growth trajectories. As the report points out, intellectual property and knowledge-based assets increasingly drive enterprise value—factors that traditional classifiers ignore.
For policymakers, the stakes are equally high. Economic statistics such as GDP, productivity, and labor market data are often aggregated using industry codes that predate the internet. If unicorns are misclassified—for instance, a gig-economy platform counted as “transportation” rather than “technology”—policymakers may underestimate the true size and contribution of the innovation economy. This can distort decisions on R&D tax credits, antitrust regulation, and infrastructure investment. The new indexes offer a more accurate baseline for measuring the economic weight of emerging technology sectors.
The economic logic behind this shift is compelling. Traditional GDP accounting treats services and goods as the primary outputs, but innovation-economy firms often produce intangible value: algorithms that reduce energy consumption, platforms that connect millions of freelancers, or AI models that accelerate drug discovery. These outputs do not fit neatly into “manufacturing” or “services” categories. The unicorn verticals implicitly recognize that the most dynamic parts of the economy are built on data, network effects, and intellectual property—and that measuring them requires a new classification language.

Conclusion: Embracing a New Lens
The innovation economy is not a niche—it is the engine of modern growth. Yet the tools used to measure it remain rooted in a bygone industrial age. As the Morningstar PitchBook report underscores, “embracing this new yardstick is crucial because the future of growth is driven by technology.” The Global Unicorn Industry Vertical Indexes represent more than just an alternative taxonomy; they are a response to a fundamental economic transformation.
For anyone navigating tomorrow’s markets—whether as an investor, a corporate strategist, or a policymaker—the lesson is clear: clinging to legacy classifications means flying blind. A company’s true identity today lies not in the product it sells but in the way it creates value. The unicorn indexes provide a framework that captures this reality, grouping firms by their technological core rather than their superficial sector. As the lines between industries continue to blur, the ability to see the innovation economy clearly will become not just an advantage but a necessity.
