IPOs—Cramer Separates the Best From the Rest

If you've been looking for new ideas, chances are you've been looking at stocks about to go public.

"So far, 2013 is turning out to be a real good year for IPOs," Cramer said. "We've seen seven deals since the new year began, and at this point all of them have made you money."

Four of them, Bright Horizons, LipoScience, CyrusOne, and Norwegian Cruise Lines all popped by double digits on their first day of trade. The other three were master limited partnership IPOs that were not so hot in their first day of trading, but have since bounced back.

"That's a darned good track record, especially when you consider that we've got five more IPOs coming next week, including Zoetis, which is the spin-off of Pfizer's animal health division," said Cramer.

However, not all IPOs are created equal.

"While January has been a fabulous month, they can't all be winners," Cramer said.

And one of the best ways to separate the best from the rest is too look back at 2012 and identify a theme. "That's a great way to figure out what's working and what isn't working," he said.

If you can extrapolate a common idea from last year's winners, chances are you can apply that idea to determine which forthcoming IPOs may have the greatest chances at success.

Following are some of 2012's best performing IPOs.

VipShop Holdings - a Chinese social media IPO. "They're a leading player in China's nascent flash sales market," Cramer explained.

Proto Labs - a company that rapidly manufacturers custom parts for prototyping. "Their technology is allowing them to take share for the traditional rapid injection molding businesses," Cramer said.

HomeStreet - a full-service community bank that operates in the Pacific Northwest. "They have a highly profitable mortgage business. Remember the housing resurgence and the rise of the regional banks are two of my top ten favorite themes for 2013," Cramer said.

Guidewire - a tech company that provides software systems to the property and casualty insurance business. "It's a niche software company with rapid growth, defensible barriers to entry, and highly visible earnings streams," said Cramer.

Intercept Pharma - an orphan drug developer. "Intercept's lead drug had very strong data and a large market opportunity. It's a company with growth that's protected and predictable," said Cramer.

Nationstar Mortgage Holdings - the largest specialty mortgage servicer in the country. "Nationstar has been aggressively taking share in the $10 trillion mortgage servicing market," Cramer said.

Eloqua - a service company that's a leader in the revenue performance management space. "Eloqua provides companies with a platform that helps them figure out the value of their marketing initiatives; that's a big challenge for many businesses," said Cramer.

WageWorks – a provider of on demand employee spending account benefits programs. "Just like companies can outsource your payroll to an ADP or a Paychex, companies can outsource the management of their flex spending accounts to WageWorks," said Cramer.

What's the one thing that all these winning IPO's have in common?

"Simple. One word. Growth," said Cramer.

"Last year, the IPOs with real, sustainable, unquestionable growth were the best performers, and this is a dynamic that should continue in 2013," he said. "I don't expect the market's appetite for growth to be easily sated."
