• C. The proportion of total market sales captured by a brand; increases indicate competitive wins or demand growth, decreases may signal threats.
• D. Percentage of customers who repeat purchase.

Answer: (C)

Market share analysis measures how much of the total market a brand captures in terms of sales, typically expressed as a percentage of market sales and tracked over time. It can be based on value or units and shows how a brand stands relative to the entire market.

Changes in market share are a read on competitive moves. If the share rises, the brand is winning more customers or benefiting from overall demand growth faster than competitors, which can come from a stronger value proposition, better distribution, smarter pricing, or more effective marketing. If the share falls, there are threats on the horizon: competitors are drawing away customers, the brand’s offerings or access are weaker, or market dynamics are shifting in a way the brand isn’t keeping pace with.

Remember, market share is a relative measure. A brand’s sales can grow while its market share declines if the market grows faster, and vice versa. This makes market share analysis a useful barometer of competitive position and how strategy translates into market demand.
