Why is it recommended that the Stars and Cash Cows of the BCG Matrix receive more marketing support than the Question Marks and Dogs?

Stars and Cash Cows in the BCG Matrix are typically high-performing products that generate significant revenue and have strong market positions. Investing more marketing support in these categories helps to maintain their competitive advantage and maximize profitability. In contrast, Question Marks may require substantial investment to determine their potential, while Dogs often do not justify further marketing efforts due to low market share and growth prospects. Therefore, prioritizing Stars and Cash Cows ensures a more effective allocation of resources for sustaining growth and profitability.
