Some tech firms’ fortunes have faded after their founder’s departure. Tim Cook has failed to put a shine on Apple since taking over from Steve Jobs. On July 23rd Apple said it made a profit of $6.9 billion in its latest fiscal quarter, a 22% drop compared with the same period of 2012.
Except that Tim Cook has been CEO since August 2011 (and interim CEO for months before that), a period which led to the massive run up in profit.
I’m not saying you can’t make this argument in a certain way, I’m just saying that’s a stupid metric by which to do it.
