美股历史上七宗最大的IPO

    2. Visa：179亿美元

    2. Visa: $17.9 billion

    世界上最大的支付卡网络运营商Visa于2008年3月推出IPO，当时正值全球金融危机最严重之时，也是美国新股市场自2001年以来最糟糕的时候。Visa将其IPO发售价格定为每股44美元，高于市场预估区间，共筹集179亿美元，成为当时美国史上最大的IPO。

    该公司的成功上市使得市场观察人士错误地以为美国股市最糟糕的时刻已经过去。事实上，标准普尔500指数在1年以后的2009年3月6日才触及经济衰退的底部。

    对于那些及早买进Visa股票的投资者而言，它是一个不错的投资标的。该股股价自首日上市以来已上涨了一倍多。

    3. 意大利国家电力公司：165亿美元

    Visa, the world's largest payments-card network, launched its IPO during the height of the financial crisis in March of 2008 and in the midst of the worst offering market since 2001. Visa priced its shares above the expected range at $44 each, raising $17.9 billion. That made it the largest U.S. IPO at that time.

    The offering's success falsely reassured market-watchers that the worst of the market collapse was over. The S&P 500 index would reach its lowest level during the recession nearly a year later on March 6, 2009.

    Visa V -1.12% has proved to be a good bet for those that got in on the ground floor. Its stock has more than doubled since its debut.

    3. Enel: $16.5 billion

    在意大利电力行业市场化改革后，意大利国家电力公司于1999年赴美上市。该公司以每股4.3欧元的IPO发行价格发售了30%的股份，共筹集165亿美元。意大利国家电力公司于当年11月1日启动上市交易，一跃成为世界上最大的公开上市电力公司。

    目前该公司已经不在纽约证券交易所（NYSE）交易。由于交易量低，该公司于2007年从该交易所摘牌退市，目前在米兰上市交易。

    Enel, the Italian power company, jumped into the U.S. public market in 1999 after the Italian government liberalized the power industry. The company sold 30% of its stock at 4.3 euros a share to raise a total of $16.5 billion. When it started trading on Nov. 1, Enel became the world's largest publicly-traded electrical utility.

    The stock no longer trades on the NYSE. It was delisted in 2007 due to low trading volumes and is now trades in Milan.
