Nearly 300 years ago at the London Stock Exchange formed an enormous speculative bubble. In the eighteenth century the trade brought exotic products, such as commodities and slaves with exorbitant profits. This benefited appropriate commercial companies like the trading company South Sea Company. Its share price exploded from 120 to 950 pounds.
