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 just cheering 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
OK, after a lull in the IPO calendar the last two weeks, things are heating up again this week. We're looking at a busy calendar, including interesting deals from Airvana, Dice, Netezza, and Orbitz, but MF Global may blow past them all to eclipse Blackstone (NYSE:BX) as the richest IPO of the year.

MF Global is a newly formed Bermuda-based holding company which holds the Man Financial brokerage unit of U.K. hedge fund manager Man Group. The company is the leading broker of exchange-listed futures and options in the world, and it provides execution and clearing services for exchange-traded and over-the-counter derivative products, as well as for other foreign exchange products and securities in the cash market. More than 130,000 active client accounts are serviced, including institutions, hedge funds, and other asset managers, as well as professional traders and private clients. Offices are located throughout the world, with the company's principal executive offices headquartered in New York.

According to data for the three months ended March 31, the company ranked first for the volume of exchanged or cleared transactions on various exchanges, including the Chicago Merc (NYSE:CME), and the New York Merc (NYSE:NMX). Revenue is derived from four main sources: commissions from agency execution; commissions from clearing services; markups from principal transactions, primarily consisting of client trades executed on a matched-principal basis; and interest income on cash balances in clients' accounts, most of which are maintained by clearing clients to meet margin requirements. For fiscal 2007, total revenue generated $5.73 billion and net income totaled $188 million, compared to total revenue of $2.6 billion and net income of $59.8 million for the prior year.

MF Global believes that its leading position demonstrates the success of its specialty-brokerage strategy, and feels that significant opportunities for business expansion lie ahead as it capitalizes on a trend toward diversified trading activities. The company has already grown through 17 acquisitions since 1989. Its business model is based on a diversified yet fully integrated structure that allows it to offer a variety of derivative and cash products across a broad range of trading markets through multiple distribution channels.

While there are many attractive reasons to think about investing in MF Global, bear in mind that while the company intends to file financial reports with the SEC and to discuss the longer-term trends in its business, it does not intend to provide quarterly or annual earnings guidance. Shares are expected to begin trading Thursday. 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.
