Bubble Characteristics

A basic characteristic of a bubble is the suspension of disbelief by most participants during the "bubble phase." There is a failure to recognize that regular market participants and other forms of traders are engaged in a speculative exercise that is not supported by previous valuation techniques. Also, bubbles are usually identified only in retrospect, after the bubble has burst. Economist Hyman Minsky identified five stages in a typical credit cycle – displacement, boom, euphoria, profit taking and panic. Although there are various interpretations of the cycle, the general pattern of bubble activity remains fairly consistent.
