The FINANCIAL -- Bubbles belong to the most fascinating phenomena in a market. Suddenly, people are willing to pay prices which are completely out of touch with the fundamental economic values of assets. In the stock market bubble of the 1920s, persons who had never before considered to become investors borrowed money and bought shares, so as not to miss out on the chance to become rich. Euphoria grew and grew, until even housewives, dock workers, and cleaning personnel had no other topic to talk about but the news from the stock markets. All this went on until in 1929 the bubble burst, triggering off the infamous World Economic Crisis.
