Paul Graham in 2015:
It would have been a good deal for Apple's board to give Steve 95% of the company.
Market cap when he came back: 1.73b.
5% now: 33b.

Today, 5% of the company is 50 bilion. Jobs became de facto chief after then-CEO Gil Amelio was ousted in July 1997 (wiki). So that would make an annualized AAPL gain of 17.3 percent, excluding dividends. Even more impressive.
