He is the man who, in the blink of an eye, is able to process huge amounts of data, draw rational conclusions, and can act without any emotion-24 hours a day, 7 days a week. Homo Economicus has an Oscar-winning role in the aforementioned theories, for their mantra is that all investors should, as a group, act the same way he does.
