Market share is best described as which of the following?

• A. A Group of Consumers Within a Larger Market Who Share One or More Characteristics
• B. The Percentage of Total Sales of a Product or Service That a Company Expects to Capture in Relation to the Competition
• C. The Total Number of People in a Particular Age Group
• D. Refers to Customers in a Particular Part of the Country

Answer: (B)

Market share measures the portion of total sales in a market that belongs to a single company, usually shown as a percentage. It captures a company’s relative size and competitive strength within that market by comparing its sales (or units sold) to the market’s total sales. This is the best description because it directly defines market share as a slice of the overall market demand, reflecting how a company performs relative to competitors. The other options describe a market segment (a group of consumers with shared characteristics), a demographic population (size of an age group), or a geographic subset of customers rather than a company’s share of total sales. Market share can be calculated using revenue or units and is a key measure for evaluating competitive position and guiding strategy.
