CEO Daily: Thursday, June 4

• The Fortune 500 are more important than ever before. Their revenues total 72% of U.S. GDP, up from 58% in 1995 and 35% in 1955. Size matters, more than ever.

• The rapid pace of technological change is their number one challenge. We know, because we surveyed the CEOs. Technological change ranked higher than cybersecurity, increased regulation, shareholder activism, shortage of skilled workers, and other popular bogeymen.

• 57% of the companies on the list weren’t there twenty years ago. That compares to a 45% turnover in the first twenty years of the list, from 1955 to 1975.

• 82% of the CEOs say they will add workers in the next two years. Lets hope they mean it.

• 84% of the CEOs say it would be easier to manage their company if it were private. They think the public markets are a drag.

And here’s a bonus fact: We asked the CEOs to name the Fortune 500 CEO other than themselves that they admired most. Top mentions: Tim Cook of Apple and Jamie Dimon of J.P. Morgan.
