The phrase "dot
-com bubble" refers to a time when there was a rapid increase and then sudden crash in the value of technology-based companies, specifically internet-related ones, during the late 1990s and early 2000s. Many investors were overly optimistic about these companies and their stock prices soared, only to plummet later when people realized their value was not as high as initially thought. So, the "dot
-com bubble" represents the rise and fall of these internet companies and the loss of investor confidence.
