An industry is a classification system for a group of companies that have similar primary business activities. The classification focuses on the core nature of operational activities, leading to a grouping of businesses that share common paths in production, services, or technology. For instance, companies that manufacture automobiles form the automotive industry.
Industry Classifications
Primary, Secondary, and Tertiary Sectors
Industries are commonly divided into three broad categories:
- Primary Industry: Involves the extraction and harvesting of natural resources (e.g., agriculture, mining, forestry).
- Secondary Industry: Entails manufacturing and construction, transforming raw materials into finished products (e.g., factories, construction companies).
- Tertiary Industry: Also known as the service sector, includes businesses that provide services rather than goods (e.g., banking, retail, healthcare).
Standard Classification Systems
Several standardized systems exist to categorize industries, making it easier for analysts, economists, and investors to compare businesses across different regions and periods:
- North American Industry Classification System (NAICS): Used by North American countries to classify businesses primarily for statistical purposes.
- Standard Industrial Classification (SIC): An older system primarily used in the United States that categorizes industries by a four-digit code.
- Industry Classification Benchmark (ICB): Often used in Europe and internationally, providing a hierarchical industry framework.
Applications in Investing
Sector-Based Investing
Investors often use industry classification to identify potential investment opportunities and diversify their portfolios:
- Sector Funds: Mutual funds and ETFs that focus on specific industries or sectors, enabling targeted investment.
- Comparison Metrics: Analysts use industry benchmarks to compare performance metrics like price-to-earnings ratios, growth rates, and profit margins within similar companies.
Economic Health Indicators
Analyzing industry performance can serve as a proxy for broader economic health:
- Leading and Lagging Indicators: Certain industries, such as construction, are considered leading indicators of economic cycles, while others like utilities might lag.
Historical Context
Evolution of Industry
Industries have evolved significantly over time:
- Industrial Revolution: Marked the transition from agrarian economies to industrialized ones in the 18th and 19th centuries, particularly in Europe and North America.
- Information Age: In the late 20th and early 21st centuries, the rise of the internet and digital technology transformed industries, giving rise to sectors like information technology and e-commerce.
Special Considerations
Emerging Industries
New technological advancements often lead to the creation of emerging industries:
- Green Energy: Driven by environmental concerns and advancements in technology.
- Fintech: The intersection of finance and technology, disrupting traditional banking and investment models.
Declining Industries
Conversely, some industries decline due to technological disruption or shifts in consumer preferences:
- Coal Industry: Declining due to environmental policies and alternative energy sources.
- Print Media: Facing challenges from digital media consumption.
