The US NASDAQ index, which has a history of 29 years behind it, suddenly surged from 2800 in October of last year to more than 5000 by March of this year. Telecommunications, Internet, and biotechnology stocks soared. The price-to-earnings ratio of some individual stocks reached 500, which some ridiculed as the "price-to-dream ratio."
就如同已有二十九年歷史的美國那斯達克指數，從去年十月中旬起，突然由二千八百點一路飆漲到今年三月中的五千多點，電信股、網路股、生化類股等輪番大漲，某些個股的本益比甚至高達五百（股價是獲利的五百倍），以致被譏為「本夢比」。
