The most commonly used classification system for stock market sectors is the Global Industry Classification Standard (GICS), which divides the market into 11 sectors. This system was developed in 1999 by MSCI and S&P Dow Jones Indices.

Here are the 11 GICS sectors:

  1. Communication Services: Includes companies in telecommunications, media, entertainment, and interactive media services (e.g., Google, Meta, Verizon).
  2. Consumer Discretionary: Companies that produce non-essential goods and services, whose demand is sensitive to the business cycle (e.g., Amazon, Tesla, Nike).
  3. Consumer Staples: Companies that produce essential goods and services, whose demand is relatively stable regardless of the economic cycle (e.g., Procter & Gamble, Coca-Cola, Walmart).
  4. Energy: Companies involved in the exploration, production, refining, and marketing of oil and gas, as well as coal and other consumable fuels (e.g., ExxonMobil, Chevron).
  5. Financials: Banks, insurance companies, real estate, and diversified financial services (e.g., JPMorgan Chase, Berkshire Hathaway, Visa).
  6. Health Care: Companies involved in pharmaceuticals, biotechnology, healthcare equipment, and healthcare services (e.g., Johnson & Johnson, UnitedHealth Group, Pfizer).
  7. Industrials: Companies that produce capital goods, provide commercial services, and offer transportation services (e.g., General Electric, Boeing, UPS).
  8. Information Technology: Companies in software, hardware, IT services, and semiconductors (e.g., Apple, Microsoft, NVIDIA).
  9. Materials: Companies that provide raw materials for various industries, such as chemicals, construction materials, metals, mining, and paper (e.g., Dow Inc., DuPont).
  10. Real Estate: Companies that own, develop, and manage real estate, including REITs (Real Estate Investment Trusts) (e.g., American Tower, Prologis).
  11. Utilities: Companies that provide electricity, natural gas, and water (e.g., Duke Energy, NextEra Energy).

It’s worth noting that there’s another widely recognized classification system called the Industry Classification Benchmark (ICB), developed by Dow Jones and FTSE Russell. While it has some differences in its hierarchical structure and how it categorizes certain industries, it also generally aims to group companies into broadly similar sectors, with a similar number of top-level categories.
