Just like opening day at the ballpark, investing in new IPOs holds the potential for shining promise and crushing disappointment. If you 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 Geovera Insurance. Given the recent strong performance of Caymans-based property and casualty reinsurer Greenlight Capital Re (NASDAQ:GLRE), which went public on May 23 and has since gained 24.4% from its offering price, this offering could be the most popular from this week's lineup.

Geovera was formed in 1993 as a division of United States Fidelity and Guaranty, which through various mergers became a unit of Travelers (NYSE:TRV) before being acquired by an investor group in November 2005. The Bermuda-based company provides specialty residential property insurance products, focused on two business lines that it believes are enduring dislocations and in which it has strong underwriting expertise. Specialty homeowners products, accounting for 59.8% of the company's business last year, are sold through a network of about 30 wholesale surplus lines brokers on a non-admitted, or excess and surplus lines basis, in hurricane-prone states. Residential earthquake products, accounting for 40.2% of the company's business last year, are sold through about 1,600 independent brokers and agents on an admitted basis in earthquake-prone states.

Geovera's finances are strong, seen in the A- rating given to its insurance subsidiaries by A.M. Best, as well as its statutory capital and surplus of $248.9 million as of Dec. 31, 2006. The company is also indemnified by United States Fidelity and Guaranty for all losses occurring prior to Nov. 1, 2005. Geovera generated revenue of $175 million and net income of $35.5 million in 2006. Through the end of the quarter closed in March, the company generated revenue of $50.3 million and net income of $13.4 million, compared with revenue of $40 million and net income of $6.3 million for the same period a year ago.

Management believes that Geovera's emphasis on its target markets; its automated, "no-exceptions" individual risk underwriting platform; and its flexibility as a non-admitted primary insurer (complemented by its strong balance sheet), will help it continue to compete profitably and to grow. The company selectively targets new areas with specialized products and focuses on profitability rather than market share. Proceeds from the offering will be used for the capital of its insurance subsidiaries, among other things.

Shares are expected to begin trading Wednesday. 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.
