Hmm you are right. But looking closer at the methodology, I find myself even more confused.

It seems the metric is something like "most successful stewards of shareholders' investments" which I guess is interesting. But now I'm tripped up on why the metric would only consider founders rather than CEOs more generally. Imagine Gates didn't start Microsoft, but instead became its CEO a month after some other founder started it and that founder sat on the beach in Hawaii while Gates did well, what he did. The founder would appear on this list but not Gates.

Edit: basically, all my intuitive "this doesn't make any sense" alarm bells are going off, but I think I need someone who really knows what they're talking about to help me understand exactly why, or what would be a more sensical version of this
