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
The game schedule is picking up and includes some interesting offerings to watch this week. Remember, "interesting" doesn't always mean "lucrative," and an offering presented as a game of the week may be selected for an intriguing aspect to the deal rather than solely for its potential return.

Let's look at Aruba Networks, a California-based company formed in 2002 which manufactures wireless network components that provide secure access to corporate data, voice, and video applications. The company's products allow a user to roam freely through a corporate environment and remote locations while maintaining secure access to network resources.

Investing in Aruba Networks is not for the faint of heart. The company has yet to turn a profit, posting a $12 million net loss for last year, up from a $32.6 million loss in 2005. The company's revenue growth is its calling card, reaching $72.5 million in 2006 from $12 million in 2005, amid increased investment in product development.

A bullish stance would point out that the market for wireless networks is maturing and that Aruba Networks benefits from a strategic relationship with Microsoft (NASDAQ:MSFT). The company's customers include Burlington Northern Santa Fe (NYSE:BNI), Google (NASDAQ:GOOG), and the U.S. Air Force. Investors may also have in mind the IPO of Riverbed Technology (NASDAQ:RVBD), a computer networking company that went public last year and remains one of the top performers over the past 12 months.

A bearish view need only point to Glu Mobile, a mobile-phone-game publisher that went public last week and struggled to remain in the black by the end of the week following a solid first-day performance. While Aruba Networks may need the cash to help foster product development, you may prefer to hold onto yours while investors reassess the climate for risky tech offerings.

Shares are expected to begin trading today. 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!
