Dot-com bubble

Written By: Ehsan Jahandarpour

The dot-com bubble (also referred to as the dot-com boom, the Internet bubble and the information technology bubble) was a historic speculative bubble covering roughly 1997–2000 (with a climax on March 10, 2000, with the NASDAQ peaking at 5,132.52 in intraday trading before closing at 5,048.62) during which stock markets in industrialized nations saw their equity value rise rapidly from growth in the Internet sector and related fields. While the latter part was a boom and bust cycle, the Internet boom is sometimes meant to refer to the steady commercial growth of the Internet with the advent of the World Wide Web, as exemplified by the first release of the Mosaic web browser in 1993, and continuing through the 1990s. The period was marked by the founding (and, in many cases, spectacular failure) of several new Internet-based companies commonly referred to as dot-coms. Companies could cause their stock prices to increase by simply adding an “e-” prefix to their name or a “.com” to the end, which one author called “prefix investing.” A combination of rapidly increasing stock prices, market confidence that the companies would turn future profits, individual speculation in stocks, and widely available venture capital created an environment in which many investors were willing to overlook traditional metrics, such as P/E ratio, in favor of basing confidence on technological advancements. The collapse of the bubble took place during 1999–2001. Some companies, such as, failed completely. Others lost a large portion of their market capitalization but remained stable and profitable, e.g., Cisco, whose stock declined by 86%. Some later recovered and surpassed their dot-com-bubble peaks, e.g.,,, whose stock went from 107 to 7 dollars per share, but a decade later exceeded 400.
