What happens when everyone is bullish in a downturn?

[Samuel Gostnell]

Just about everyone expects a downturn to occur soon, although probably not nearly as impactful as 2008. Most of the investors I know are anticipating, if not excited, for a downturn to happen. In retrospect, 2008-2013 had a lot of great opportunities, and people want to capitalize on that. Let’s say a downturn happens, and investors are ready for it, won’t that counteract the effects of a downturn? I hope I explained that effectively... any thoughts?
