• Stars are units with a high market share in a fast-growing industry. They are graduated question marks with a market- or niche-leading trajectory, for example: amongst market share front-runners in a high-growth sector, and/or having a monopolistic or increasingly dominant unique selling proposition with burgeoning/fortuitous proposition drive(s) from: novelty, fashion/promotion (e.g. newly prestigious celebrity-branded fragrances), customer loyalty (e.g. greenfield or military/gang enforcement backed, and/or innovative, grey-market/illicit retail of addictive drugs, for instance the British East India Company's, late-1700s opium-based Qianlong Emperor embargo-busting, Canton System), goodwill (e.g. monopsonies) and/or gearing (e.g. oligopolies, for instance Portland cement producers near boomtowns),^{[ citation needed ]} etc. The hope is that stars become next cash cows.

Stars require high funding to fight competitors and maintain their growth rate. When industry growth slows, if they remain a niche leader or are amongst the market leaders, stars become cash cows; otherwise, they become dogs due to low relative market share.
