Speculative Bubble

Speculative Bubble

A situation in which prices for securities, especially stocks, rise far above their actual value. This trend continues until investors realize just how far prices have risen, usually, but not always, resulting in a sharp decline. Speculative bubbles usually occur when investors, for any number of reasons, believe that demand for the stocks will continue to rise or that the stocks will become profitable in a short time. Both of these scenarios result in increased prices.

A famous example of a bubble is the dot-com bubble of the 1990s. Dot-com companies were hugely popular investments at the time, with IPOs of hundreds of dollars per share, even if a company had never produced a profit and in some cases, had never earned any revenue. This came from the theory that Internet companies needed to expand their customer bases as much as possible and thus corner the largest possible market share, even if this meant massive losses. NASDAQ, on which many dot-coms traded, rose to record highs. This continued until 2000, when the bubble burst and NASDAQ quickly lost more than half of its value. Other famous examples include the tulip mania of the 1630s and the housing bubble in the early 2000s.
