Irrational people like Calhoun expect a crash at all times.
Yes, but also equally there's people that ignore all the warning signs, when the probability actually does favor a larger pullback. That is equally as weak of logic and irrational. However, to be fair equity markets are naturally bullish bias, so it's general better to have that view, than to be a perma bear. You have to look at the case, technical analysis and facts. Not just say "well this person is always calling for a crash so he must be wrong".
