The 5 Best and Worst IPOs

The market for equities has gone through numerous crises, bubbles and ups and downs, but when an initial public offering hits the market, it can create lots of excitement for investors and can generate perhaps billions of dollars for the company.

Market conditions can be a major factor in determining when companies decide to file, and market optimism or pessimism can influence the value of shares, often to the detriment of the company or the investor.

In 2000, companies filing IPOs generated $96.9 billion in the market, but after the dot-com bust, many of these offerings proved significantly overvalued and the market for IPOs dropped to a decade-low $15.2 billion in 2003, according to Renaissance Capital.

This year, Facebook is expected to raise as much as $16 billionthrough its offering, which would be more than double the $12 billion proceeds from 68 IPOs so far this year. After being reported that Facebook’s IPO was oversubscribed,the company increased its price range, as well as shares offered.

With the hotly anticipated Facebook public listing in mind, the CNBC Analytics team looked into IPOs from 2000 to the present to see which ones have been the most — and least — successful in the market since their first offering. The companies are ranked by the total percentage increase and decrease from original listing prices as of market close on May 14, 2012. All IPOs included in this data set have had gross proceeds of $1 billion or greater and excludes SPACs (Special Purpose Acquisitions Company), closed end-funded, and non-operating trust deals.

So, which IPOs had the best and worst performance since 2000? Click ahead to find out.
