Stars: The business units or products that have the best market share and generate the most cash are considered stars. Monopolies and first-to-market products are frequently termed stars. However, because of their high growth rate, stars also consume large amounts of cash. This generally results in the same amount of money coming in that is going out. Stars can eventually become cash cows if they sustain their success until a time when the market growth rate declines. Companies are advised to invest in stars.
