Marketing Dynamics: Theory and Practice
Star: High-growth market leaders are
called stars. They generate large
amounts of cash. The Star companies
represent probably the best profit
opportunity available to a company, and
their competitive position must be
maintained. If a star’s share is allowed
to slip because the star has been used
to provide large amounts of cash in the
short run or because of cutbacks in
investment and rising prices (creating
an umbrella for competitors), the star
will ultimately become a dog. The
ultimate value of any product or service is reflected in the stream of cash, it generates net of its own
re-investment. For a star company, this stream of cash lies in the future growth to obtain the real
value, the stream of cash must be discounted back to the present at a rate equal to the return on
alternative opportunities. It is the future payoff of the star that counts, not the present reported profit.
For GE, the plastics business is a star in which it keeps investing. As a matter of fact, the company
has even acquired Thomson’s plastics operations (a French company) to further strengthen its position
in the business.
Cash Cow: Cash cows are characterized by low growth and high market share. They are net
providers of cash. Their high earnings, coupled with their depreciation, represent high cash inflows,
and they need very little in the way of reinvestment. Thus, these companies generate large cash
surpluses that help to pay dividends and interest, provide debt capacity, supply funds for research and
development, meet overheads, and also make cash available for investment in other products. Thus,
cash cows are the foundations on which everything else depends in the business. Technically, a cash
cow has a return on assets that exceeds its growth rate. Only if this is true will the cash cow
generate more cash than it uses. For example, the tyre business can be categorized as a cash cow
for Goodyear Tyre and Rubber Company. The tyre industry is characterized by slow market growth,
and Goodyear has a major share of the market.
Problem Child: Products in a market with a low share are categorized as problem child. Because of
growth, these products require more cash than they are able to generate on their own. If nothing is done
to increase market share, a problem child will simply absorb large amounts of cash in the short run and
later, as the growth slows down, become a dog. Thus, unless something is done to change its perspective,
a problem child remains a cash loser throughout its existence and ultimately becomes a cash trap. What
can be done to make a problem child more viable? One alternative is to gain share increases for it.
Because the business is growing, it can be funded to dominance. It may then become a star and later,
when growth slows down, a cash cow. This strategy is an expensive one in the short run. An abundance
of cash must be poured into a question mark in order for it to win a major share of the market, but in the
long run, this strategy is the only way to develop a sound business from the question mark stage.
Another strategy is to divest the business. Outright sale is the most desirable alternative. But, if this
does not work out, a firm decision must be made not to invest further in the business. The business must
simply be allowed to generate whatever cash it can while none is reinvested.
