What is the BCG (Boston Consulting Group) matrix?
The BCG matrix is a portfolio analysis tool used to evaluate a company’s products or strategic business units (SBUs) based on market growth rate and relative market share, helping managers decide where to invest, hold, harvest, or divest.
Why is relative market share important in the BCG matrix?
High relative market share suggests cost advantages due to economies of scale, learning effects, and stronger bargaining power, which improve profitability.
What are the two dimensions of the BCG matrix?
- Market growth rate (vertical axis): indicates market attractiveness and future potential.
- Relative market share (horizontal axis): measures competitive strength compared to the largest competitor.
What does market growth rate indicate?
Market growth rate reflects the stage of the product life cycle and signals how much investment is needed to compete effectively in the market.
What is a Star in the BCG matrix?
- High market growth
- High relative market share
- Require heavy investment to maintain leadership
- Likely to become Cash Cows as market growth slows
- Strategy: invest and defend position
What is a Cash Cow in the BCG matrix?
- Low market growth
- High relative market share
- Generate more cash than they consume

What is a Question Mark in the BCG matrix?

What is an unbalanced portfolio in the BCG matrix?
A portfolio with too many Dogs or Question Marks and too few Cash Cows, leading to cash shortages and weak long-term growth.
