How Steve Jobs Helped Guarantee Tim Cook’s Success At AppleLast week, Tim Cook celebrated his anniversary of being Apple s CEO. He assumed this role before Steve Job s death and has done what my British friends would be called a Bang-Up job. The two charts below show exactly how successful Cook has been since he took over the CEO role. Apple s market cap went from billion to trillion in those ten years. And Apple s share price grew tenfold under his leadership.Apple s share price growth under Tim Cook’s leadership for the last ten years.When Tim Cook took over as CEO, I was bombarded with media and other industry requests about Cook and was asked if I thought he could be successful. I went on record on both TV and in print saying that Tim Cook was not only the right person to take this role, but that I was extremely bullish about his success potential. I was certain of this because I had a strong knowledge of Job’s role of preparing Cook for the CEO position. I got a lot of negative feedback for my viewpoint, and those who remember this time saw a lot of negative commentary about Cook that neither he nor anybody else could replace Steve Jobs.
