How can sales increase but market share decrease?

Sales can increase while market share decreases if the overall market is growing at a faster rate than a company's sales growth. For example, if a company experiences a rise in sales due to effective marketing or new product launches, but competitors are growing even faster or entering the market with innovative offerings, the company's share of the total market may decline. Additionally, if the company raises prices or shifts its focus to higher-margin products, it might boost sales revenue while potentially losing customers to competitors who offer more value.
