In business and finance, a sector refers to a distinct category or grouping of companies, organisations, or industries that share similar characteristics, products, or services.

What is a sector?

Sectors are used to classify and analyse various parts of the economy based on commonalities such as the nature of the business, target market, and production methods. Understanding sectors is crucial for investors, analysts, policymakers, and business leaders as it provides insights into economic trends, investment opportunities, and risk assessment.

Characteristics of a sector:

  1. Common attributes: Sectors typically consist of businesses that share similar characteristics, such as production processes, customer demographics, and market dynamics.
  2. Market focus: Sectors are defined by the markets they serve. For example, the technology sector focuses on products and services related to information technology.
