2018 Corporate Longevity Forecast: Creative Destruction is Accelerating | InnosightImagine a world in which the average company lasted just 12 years on the S&P 500. That’s the reality we could be living in by 2027, according to Innosight’s biennial corporate longevity forecast. There are a variety of reasons why companies drop off the list. They can be overtaken by a faster growing company and fall below the market cap size threshold (currently that cutoff is about $6 billion). Or they can enter into a merger, acquisition or buyout deal. At the current and forecasted turnover rate, the Innosight study shows that nearly 50% of the current S&P 500 will be replaced over the next ten years. This projection is consistent with our previous analysis from 2012 and 2016, which Innosight originally conducted with Creative Destruction author Richard Foster.
