前三

Largest Internet Bubble Ever: The dot-com bubble, peaking on March 10, 2000, saw the Nasdaq Composite index rise 600% between 1995 and its peak, only to fall 78% by October 2002, wiping out $5 trillion in market capitalization.
2000年市值蒸发榜: During the dot-com crash, companies like Cisco lost 80% of its stock value, Amazon's stock fell over 90%, and Lucent Technologies crashed by nearly 99% from its peak.
Bubble Burst Precursors: Key signs of a market bubble include rapidly climbing prices far exceeding intrinsic value, stretched valuations, irrational exuberance, high margin trading, and a loss of breadth in the market.
