Stability Amid Turmoil
One of the most striking things about this year’s list of the best-performing CEOs is how consistent it is with last year’s. Fully 70% of the leaders in our 2018 ranking are returnees. That stability is reflected in the average tenure of the CEOs—16 years, compared with 7.2 years for S&P 500 CEOs in 2017. These are extraordinarily turbulent times, and the longevity of our top 100 is remarkable.
