????2. Visa：179億美元

????2. Visa: $17.9 billion

????世界上最大的支付卡網絡運營商Visa于2008年3月推出IPO，當時正值全球金融危機最嚴重之時，也是美國新股市場自2001年以來最糟糕的時候。Visa將其IPO發售價格定為每股44美元，高于市場預估區間，共籌集179億美元，成為當時美國史上最大的IPO。

????該公司的成功上市使得市場觀察人士錯誤地以為美國股市最糟糕的時刻已經過去。事實上，標準普爾500指數在1年以后的2009年3月6日才觸及經濟衰退的底部。

????對于那些及早買進Visa股票的投資者而言，它是一個不錯的投資標的。該股股價自首日上市以來已上漲了一倍多。

????3. 意大利國家電力公司：165億美元

????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

????在意大利電力行業市場化改革后，意大利國家電力公司于1999年赴美上市。該公司以每股4.3歐元的IPO發行價格發售了30%的股份，共籌集165億美元。意大利國家電力公司于當年11月1日啟動上市交易，一躍成為世界上最大的公開上市電力公司。

????目前該公司已經不在紐約證券交易所（NYSE）交易。由于交易量低，該公司于2007年從該交易所摘牌退市，目前在米蘭上市交易。

????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.
