Growth Industry: Definition, Drivers, Characteristics, and Measurement

What is a growth industry?

A growth industry is an economic sector that expands at a faster-than-average rate compared with other sectors. These industries often arise from new technologies, shifting regulations, or changing consumer preferences that create demand for novel products and services. They typically attract heavy investment and public attention as firms within the sector report rapidly rising sales and future growth potential.

Key drivers of growth industries

  • Technological innovation
    New or improved technologies can create entire markets or transform existing ones. Examples include the smartphone revolution, virtual reality (VR), machine learning, big data analytics, and other digital platforms that enable new products and business models.

  • Regulatory change
    Loosening or reform of laws and regulations can enable previously restricted markets to expand. Examples include healthcare and insurance policy shifts, energy-market deregulation, and legalization or decriminalization of certain substances.

  • Changing consumer preferences and lifestyle shifts
    Greater disposable income, more leisure time, and new delivery channels (e.g., apps and platforms) can spur growth in travel, shared-economy services, and experiences. Companies like Airbnb and ride-hailing platforms illustrate how consumer behavior can create fast-growing sectors.

Common characteristics

  • Rapid, consistent revenue growth across firms in the sector
  • Heavy investment inflows and strong media attention
  • Elevated valuations driven by expectations of future expansion
  • Higher volatility and risk compared with mature industries

Typical risks

  • High cash burn and slow or absent profitability despite strong revenue growth
  • Overvaluation and speculative bubbles
  • Technological setbacks or competitive disruption
  • Regulatory reversals or legal uncertainty

Measuring growth: CAGR

Analysts often use the compound annual growth rate (CAGR) to compare and assess growth over multi-year periods. CAGR smooths year-to-year volatility to give an average annualized growth rate.

Formula:
CAGR = (Ending Value / Beginning Value)^(1 / Number of Years) – 1

Example: If an investment grows from 100 to 150 over three years:
CAGR = (150 / 100)^(1/3) – 1 ≈ 0.1447, or about 14.5% per year.

Note: CAGR summarizes growth but does not capture interim volatility or external market conditions.

Examples

  • Technology sector: rapid innovation across hardware, software, and platform services has produced major growth companies and market shifts.
  • Renewable energy and electric vehicles: technology improvements and supportive policies have driven investor interest (e.g., high valuations for some EV firms).
  • Medical and recreational cannabis: regulatory changes and increasing research and commercial activity have created new markets for products and services.

Takeaways

  • Growth industries expand faster than the economy at large, driven by innovation, regulation, and consumer change.
  • They offer significant upside but come with elevated risk, including volatility, cash burn, and regulatory exposure.
  • Tools like CAGR help compare growth performance, but investors should complement such metrics with qualitative analysis of technology, competition, and regulatory environment.
