Define Market Share in Simple Terms

Market share is complementary with a company growing or shrinking.

When the market share of a company increases or decreases, it gives analysts information on how competitive that company’s goods or services are at that particular time.

If the total market for a product or service grows, and a company maintains its market share, it means it is growing revenues at the same rate as the total market.

If it is growing its market share, its revenue is growing faster than the total market revenue.
