This is false. A CEO's job is to run the company. The Board's job is to protect a shareholder's investment, which does not mean maximizing it.
The lie that a CEO's job is to maximize shareholder's value didn't become a popular meme until CEOs were suddenly awarded large stock compensation grants during the Reagan era, and is entirely about CEOs maximizing their personal holdings to the detriment of every other shareholder.
CEOs raiding short term coffers is a different issue.
This is defending the short term stock value and nothing else.
