The CEO is the throughline in a history
    of billion-dollar blunders

Since the IPO, he created an annual ROI of 21% for his investors. Taking risks means blunders are part of the way I would say.

For comparison:

He outperformed the Nasdaq 100 which made 18% (plus dividends) in the same time.

And he way outperformed Warren Buffet who made 14% in the same time.
