BCG matrix
Also written BCG analysis · Boston Consulting Group matrix
The Boston Consulting Group's grid classifying a company's business segments as Stars, Cash Cows, Question Marks or Dogs by market growth, market share and cash generation.
In plain language
Porter's model and PESTLE look at industries and economies. The BCG matrix looks inside one company, at its business segments, as a portfolio.
Each segment is placed by how fast its market is growing and how strong the company's position in it is, and that placement says what the segment does for cash: generate it, consume it, or neither. A company with a healthy mix uses its cash generators to fund the bets that might become tomorrow's leaders.
How it works
Section 6.6.3 describes the matrix as looking at segments "through the lenses of market growth and cash generation", and defines the four boxes:
| Box | Market | Company's share | Cash | Workbook example |
|---|---|---|---|---|
| Star | Growing rapidly | Large | Increasing cash generation over time | Cera Sanitaryware |
| Cash Cow | Low growth | Established | Steady cash; little investment needed to hold share | Navneet Publications; Colgate |
| Question Mark | Fast-growing | Low | Right strategy and investment can grow share, but may consume cash and never generate enough | Tata Nano (did not succeed); Bajaj Pulsar (succeeded) |
| Dog | Slow growth, intense competition | — | Low cash generation | — |
On Navneet, the workbook's reasoning is the textbook cash cow: steady, predictable growth, a strong brand, a penetrated distribution channel and a strong balance sheet — all the company needs to do is update content when syllabuses change.
The workbook concludes that the matrix gives "an interesting sense of the businesses/segments in terms of their attractiveness for the investors".
A worked example
Illustrative figures, Rs crore. A diversified consumer company with four segments:
| Segment | Market growth | Company share | Annual cash flow | Box |
|---|---|---|---|---|
| Packaged snacks | 18% | 30% | +220 | Star |
| School notebooks | 4% | 35% | +400 | Cash Cow |
| EV charging points | 40% | 3% | −250 | Question Mark |
| Printing services | 1% | 4% | +10 | Dog |
Cash from Cow and Star = 400 + 220 = Rs 620 crore
Cash consumed by Question Mark = Rs 250 crore
Net after funding the bet = Rs 370 crore (plus 10 from the Dog = 380)
The analyst's questions follow from the grid. Can the notebook business keep throwing off Rs 400 crore without investment? Is Rs 250 crore a year buying share in EV charging, or just burning cash like the workbook's Tata Nano? And why is capital still tied up in printing?
For valuation, the grid leads naturally to a sum-of-the-parts approach, since each box deserves a different multiple.
Why NISM asks about it
Chapter 6 (Industry Analysis) lists the BCG matrix among the industry landscaping frameworks in section 6.6 and names Indian examples for each box. Questions typically describe a segment and ask which box it belongs to, or ask which framework looks at a company's segments rather than an industry or economy.
Common exam traps
- High growth + low share = Question Mark; low growth + strong share = Cash Cow. Swapping these is the standard error.
- A Question Mark is not a failure. Bajaj Pulsar started as one and succeeded; Tata Nano did not.
- Cash Cows need little investment to hold share — that is where their cash comes from.
- BCG analyses a company's own segments. Porter and PESTLE analyse industries and economies; the workbook draws the contrast itself.
- Stars generate increasing cash in the workbook's definition — do not assume every high-growth segment is a cash drain.
Check yourself
1.In the BCG matrix, a business segment operating in a fast-growing market but holding a low market share is classified as a:
- a)Star
- b)Cash Cow
- c)Question Mark
- d)Dog
Show the answer
Answer: (c) Question Mark
A Question Mark is in a fast-growing market but with a low market share. The right strategies and investments can grow that share, but the segment also risks consuming cash and still not generating enough. The workbook offers Tata Nano as a question mark that did not succeed and Bajaj Pulsar as one that did.
Option A is wrong: a Star is rapid growth plus a large market share, and generates increasing cash over time (Cera Sanitaryware). Option B is wrong: a Cash Cow has low growth but an established share, needs low cash infusion and steadily throws off cash (Navneet Publications, Colgate). Option D is wrong: Dogs have slow growth and intensive competition, hence low cash generation.
Star and Question Mark share the fast-growing market — the market share is what separates them.
