Why bullish consensus is a valuable market indicator

Bullish consensus is the percentage of people (traders, farmers, technicians, market analysts, etc.) who think the price of a given commodity or stock will move higher in the next several weeks to a few months. The concept behind bullish consensus, aka contrary opinion, is if the vast majority of market participants think a price will go up, they have already bought or stopped selling. [...]that, ladies and gentlemen, is why bullish consensus is such a valuable market indicator. A bullish consensus of 70% is over-bought; 80% means the price is very likely to crash and over 90% is when you empty your bins, sell the next two year’s crops, mortgage farm and your first born to short the futures.
