Just like opening day at the ballpark, investing in new IPOs holds the potential for shining promise and crushing disappointment. If you simply can't bear to just cheer on your favorites from the sidelines, at least be careful about investing in this league. Many new issues swing for the fences during their first trading days, only to slump once marketing hype has given way to mundane earnings reports.

Don't commit an error by stocking your entire portfolio with rookies. Allocate just a small percentage of your risk capital to IPOs. Scout your potential phenoms carefully, and be choosy about composing your own rotisserie league. Investing with an eye for a season extending long beyond opening day will reward you with quality players capable of staying in the game. With that in mind, we offer our Foolish scouting report of the latest IPOs.

Game of the week
Let's take a look at LDK Solar, which looks to shine brighter than the biopharmaceuticals with which it is sharing the field this week.

The Chinese solar wafer manufacturer, founded in 2005, employs roughly 3,145 employees. The company produces multicrystalline solar wafers which are the principal raw material used to make solar cells that convert sunlight into electricity. The majority of the company's sales so far have been in China. 

LDK Solar generated revenues of $105.5 million and net income of $25.9 million in 2006, compared to zilch in the revenue column and a net loss of $274,000 for the prior year. Through the end of the quarter ended in March, the company generated revenues of $73.4 million and net income of $21.6 million compared to no revenues and a $440,000 net loss for the same period a year ago.

LDK Solar believes that its rapid growth and strong market position are attributable to its status as a pure-play multicrystalline solar wafer manufacturer, cost-effective production, large-scale manufacturing capacity, strong relationships, and experienced management. The company seeks to strengthen its position by increasing production capacity and improving cost competitiveness. Proceeds from the offering will be used to expand its production capacity, secure polysilicon feedstock which is in short supply, boost research and development, and for general corporate purposes, including potential acquisitions.

Demand for solar cell manufacturers has been strong. Since December 2005, eight IPOs have been priced. First Solar (NASDAQ:FSLR), the only U.S. firm, leads the pack in terms of aftermarket performance, returning 233.6% as of last Friday. The other seven are Chinese companies, which have also performed well. Trina Solar (NYSE:TSL), which debuted in December, is now up 164.5%, and the most recently priced company, China Sunergy (NASDAQ:CSUN), which went public May 16, is now up 24.1%.

Shares are expected to begin trading Friday. As always, make sure you do your own warm-ups and read through a company's offering documents, including the risk factors, before getting in on the game!
