NASDAQ and other similar systems allow computerized trading, linking investors with brokers and dealers both on a domestic and an international level. Such systems quote the highest bids and lowest asking prices on all securities, giving investors the opportunity to make optimum deals. In 1986, the London Stock Exchange created a computer-based network similar to NASDAQ with its deregulation move called "Big Bang." It connected London to a group of international securities dealers, making the city's trading floor largely obsolete.

Many contended that securities fraud of this sort was a result of deregulation of the securities industry since at least the early 1980s, with an attendant relaxation of supervision by the U.S. Securities and Exchange Commission (SEC). The 1990s saw a renewed and accelerated effort by the SEC and other regulatory agencies to regulate the securities industry. In the early 21st cent. regulation once again eased while a number of widely traded financial products relating to securities, such as credit default swaps, remained unregulated; this, in addition to the housing bubble and resulting credit crunch, were widely regarded as contributing to the stock market meltdown in Sept.–Oct., 2008.
