There are some fund managers ceo's with very high iq's, ie 170's, I didn't say that was normal though. I do argue that they would have iq's in the 130 and above range, bare minimum. Afterall the guys who make it to the top are probably a fair bit smarter than the average finance grad. I would estimate that most ceo's are in the 130's atleast and most fund managers are in the 140's atleast. Plus a fund manager has to be intuitive as well, in predictions which isn't measured by these tests. And for all the talk of female intuition, I've rarely heard of any who actually make real money in the stock market, most of them are too risk averse.
At 130 there are about twice as many men as women and going beyond that, the 140's is 2.5 etc the gap widens. You're right, the average finance grad is about 125, physics is 133. However its becoming a lot more common for stem grads to now become hedge fund managers or work in the investment field. They have the best minds in aggregate and the securities industry is where the money is.
Frankly that's one of the big complaints in academia right now, that all the super smart people are becoming fund managers instead of becoming scientists, because of the money.
