Company valuations rise and fall by human emotions as opposed to business facts. The current state of human thought cannot comprehend all business in the way they should be properly valued(cash flows, profitability, and price). A business valuation should not be determined by thoughts/preceptions(our preceptions rarely correspond with reality, humans consistently make mistakes its in our nature) but by facts.
Humans are increasingly unstable, lack original thought processes, and the ability to make clear judgement. Judgement is skewed by sources influencing thoughts. As most are preoccupied filling the void with media influenced story lines. Media has no incentive to create positive news as its realized a revenue model of doom and gloom. People perceive its bad out there but the ones making the decisions actually have it good b/c they are working and earning capital to realize goods and services. So their thoughts are flawed. They have no ability to know what bad really is. What does poor economic GDP really mean? US citizens have no clue what poor economics are, poor economics are when you get bombed every couple of days, put in jail without a fair trail, property rights are determined by AK-47's, and lacking consistent edible food.
Some ultra wealthy understand the flawed human complex and thus can make long term judgments that reflect long term results. The human brain reacts to quickly and without comprehension of reality. Its more likely to choose flight over fight.
The new environment needs limited human interaction and less trading.
