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
When there's only one game on the schedule, one might as well pay attention.

Oculus Innovative Sciences is a California-based pharmaceutical company formed in 1999, which develops products aimed to prevent and treat infections arising from wounds. The company's main technology is Microcyn, a topical non-toxic super-oxidized water solution designed to treat organisms which cause disease.

The company believes that the cost-effectiveness and ease of use of its products can help it become a global leader in wound care. Oculus does not yet have regulatory approval to market Microcyn in the U.S. As with many start-ups, the company has a history of losses. For the past six months ended Sept. 30, the company had an accumulated deficit of $59.3 million.

Oculus hopes to raise $31.5 million, reduced from its original $40 million goal. While some medical-related companies achieved great performances last year, others were wash-outs. A safer bet, in order to guard against any infection in your portfolio, would be to sit this game out and forego some potential upside while waiting for FDA clearance and further signs of viability.

As always, make sure you do your own warm-ups, and read a company's offering documents before getting in on the game!

Groupies & fan clubs
If you don't want to declare your loyalties for specific players, but still want to enjoy the action, consider subscribing to an IPO-focused mutual fund or exchange-traded fund. Of course, do your scouting homework here, too, and make sure you read their prospectuses before buying season tickets.

Last week, the IPO-focused funds performed better than the general market, with the IPO Plus Aftermarket (FUND:IPOSX) mutual fund scoring a 3.9% gain, and the First Trust IPOX 100 (AMEX:FPX) ETF rising 3%. Still turning in solid returns, the Nasdaq posted a 2.8% advance, and the Russell 2000 gained 2.5%.
