ABSTRACT
For the public at large, financial rumors correspond to mythical phenomena. The very term "finance" immediately conjures up spectacular buyout operations on the stock exchange, historic crashes, insider information leading to the swift amassing of colossal fortunes, and so on. The study of financial rumors poses certain particular problems that make it both very difficult and all the more fascinating. These rumors are very localized and fleeting. By concretely examining financial rumors, one could see why, theoretically speaking, financial rumors are inevitable. In theory there is no room for rumors in the world of high finance. Financial markets are supposed to represent models of rationality. In practice, the Stock Exchange and other financial markets run rampant with rumors. Quite simply, the Stock Exchange and other financial markets contain within themselves most of the parameters that favor the natural blossoming of rumors. At present financial decision made at the Stock Exchange is a wager or gamble on the future.
