Investor psychology
Investors should learn to recognize market patterns. Study market history in order to better understand the implications of today’s events. Ironically, investor psychology and market cycles — which both seem flighty and unpredictable in the short term — fluctuate in ways that have more for regular patterns when viewed over the long term .
Watch for moments when most people are so optimistic that they think things can only get better, an expression that usually serves to justify the dangerous view that “there’s no price too high.” Likewise, recognize when people are so depressed that they conclude things can only get worse, as this often means they think a sale at any price is a good sale.
