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.

Games of the Week
If last week's solid performances didn't inspire you, this week's array of interesting offerings just might.

Among the players going to bat are Cellcom Israel, the leading Israeli telecom; 3SBio, a profitable Chinese pharmaceutical; and Accuray, the only maker of commercially available intelligent robotic radiosurgery systems. And don't forget J.A. Solar Holdings, a Chinese manufacturer of solar panels hoping to achieve the financial success of Solarfun Power Holdings and Trina Solar, two competitors that went public several months ago and have been performing well.

Of particular note is the offering by Fortress Investment Group, which will mark the first IPO of a diversified U.S. private equity and hedge fund. The New York-based company, organized in 1998, has seen its assets grow from $1.2 billion at the end of 2001 to $29.7 billion at the end of last September, and net income growth from $40.3 million in 2003 to $192.7 million in 2005. Nomura Holdings (NYSE:NMR) recently purchased 15% of the company.

The offering involves a piece of the lucrative pie of management fees and investment income from the Fortress family of hedge and private equity funds. The company anticipates paying dividends equaling about 75% of its annual distributable income.

While an investment in Fortress could bring glamour to your portfolio, don't expect it to serve as a conservative bulwark. Earnings over time will likely be volatile, reflective of the alternative investment experience.

The company hopes to raise up to $635 million, and shares are expected to begin trading on Thursday. A successful offering could herald an influx from other hedge funds.

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!
