We group the companies on this site into Sectors and Industry Groups using the Global Industry Classification Standard (GICS).

In the context of the hierarchy, the GICS sectors represent a hierarchical categorisation of companies based on their primary business activities. The GICS classifies companies into sectors, industry groups, industries, and sub-industries facilitating industry analysis and comparison.

The Sector Hierarchy

The GICS hierarchy starts with the highest level, which is the sector. There are 11 GICS sectors, each representing a broad area of economic activity. These sectors are:

  1. Energy: Companies involved in the exploration, production, or distribution of energy resources, including oil, gas, and coal.
  2. Materials: Companies engaged in the extraction, processing, and distribution of raw materials such as chemicals, construction materials, metals, and mining.
  3. Industrials: Companies involved in the production and distribution of goods and services used in construction, manufacturing, and transportation. This sector includes aerospace, defense, machinery, and transportation services.
  4. Consumer Discretionary: Companies that produce goods and services considered non-essential, typically related to consumer spending. This sector includes industries like automobiles, hotels, restaurants, apparel, and leisure.
  5. Consumer Staples: Companies involved in the production and distribution of essential consumer products such as food, beverages, tobacco, and household goods.
  6. Health Care: Companies engaged in the production, development, and distribution of medical goods, pharmaceuticals, and health care services.
  7. Financials: Companies providing financial services such as banking, insurance, investment management, and real estate.
  8. Information Technology: Companies involved in the development, manufacturing, and distribution of technology products and services, including software, hardware, and IT consulting.
  9. Communication Services: Companies that provide communication and content delivery services such as telecommunications, cable TV, internet services, and media.
  10. Utilities: Companies engaged in the provision of essential services such as electricity, gas, and water supply.
  11. Real Estate: Companies involved in the development, management, and leasing of real estate properties.

Each of the above GICS sectors are further divided into industry groups, industries, sub-industries, and individual companies. The GICS hierarchy provides a standardized framework that helps investors, analysts, and researchers classify and compare companies within and across sectors.
