How many have law degrees? The majority of CEOs in the top 100 were not engineers it seems.
And performance is stock performance/TSR, if I understand correctly.
Edit: How is it sea lioning if your link is not establishing what you claim? An intrinsic link between being an engineer and being a high performance CEO would, for example, be that proportionate more engineers than MBAs, etc. are good CEOs.
That just compares MBAs and engineers (not sure what happens if someone has both), not the many other non-engineer educations CEOs can have (law, mathematics, physics, ...). MBA is quite US centric.
Yes, that's what we are all saying.
