For sure. Traders are (or at least were) a special breed. It was mostly young white men, a lot of them with quick reaction times and poor impulse control. The job required outsized self-confidence, and then rewarded it with a lot of money, which often turned into fast living. I worked with some who were pretty decent people, but the median trader on the floor then was an arrogant, braying jackass.
This is middle school stuff. Plenty of adults act this way under certain circumstances.
