The Best CEO In The USADefining "best" for a CEO is tricky. You could argue a visionary like Elon Musk is #1. After all, he built $TSLA, is now a board member of $TWTR and has unmatched influence in terms of social outreach. You could argue Tim Cook of $AAPL for keeping the vision alive after the passing of Steve Jobs. But one CEO has done something others haven't: saved a fading star. Over the last 7 years, Satya Nadella has taken $MSFT to new heights. He's refocused the core business, abandoning failed attempts at competing with the iPhone. $MSFT is a 2.3 trillion dollar business. It's hard to imagine it getting that far without Nadella at the helm.
